Template:Yasaka Uchiha

, also known by the alias of, is a missing-nin from Kumogakure. He originally served in the village as a gifted Jōnin, before defecting to temporarily assist Arienai in his goals, training with him for several years. While he has not yet made any advances towards Arienai's goals, Yasaka keeps in contact with him often. More recently, Yasaka has also become a member of the Akatsuki.

Early Life
Yasaka was born in Kumogakure to a small family consisting of himself, his mother, his younger sister Etsuko, and his father, Sawaru. As Sawaru was known to have been a very influential, but slightly shady politician and a retired shinobi who was in the high graces of the feudal lord and other noble families, his life was active and busy, and he never truly found the time to relax with the rest of his own family. During the few times when he did, the man always mentioned his career, lecturing his children about power and how it worked in the world. Yasaka seemed to become negatively affected by the lack of his father's presence and guidance, developing less tolerance of the opinions of others, and becoming overly adamant about his choices. Nevertheless, he got along well with his sister and mother, both of whom he loved very much. Although he could always tell that something was missing, he was content with his life; the family was supported well, and he had few troubles. Even though it seemed as if he barely knew his own father, Yasaka still regarded him as family.

At the age of 6, Yasaka was enrolled into the academy and his life as a shinobi began; he stated that he had desired to follow a path different from that of his father, expressing a great dislike for organized politics. He was known to have even mocked the concept of a kage at one point, regarding it as a dictator-like position for petty reasons. In the academy itself, Yasaka was punished often for blunt and offending remarks to others. Instructors observed that he always seemed to assume the role of a "ringleader", controlling others through their emotions and feelings to benefit himself. Though regarded as a troublemaker, he was nothing short of a genius; Yasaka placed at the top of most of of his classes, performing on a level that astonished the instructors. He had a special talent for Kumogakure's widely practiced Kenjutsu techniques, even developing his own style at such a young age. Some of his success could be attributed to his stubbornness, though he hated having to work in teams for tasks.

Yasaka would graduate from the academy and become a Genin seven months after his entry, solidifying his status as a prodigy and a fast learner. His mother presented him with a violin as a gift, which he eagerly accepted, being an avid appreciator of music; it became his most prized possession. When Etsuko inquired about Sawaru's thoughts, the man bluntly stated that he didn't have time for such matters, and that Yasaka didn't have what it takes to become a true shinobi due to his greedy tendencies. His words actually left Yasaka feeling distanced from his father even more than before. Feeling that his father had refused to adknowledge him, Yasaka began to dislike the man. Even without his father's support, he continued to hone his abilities, and eventually reached the rank of Chūnin at the age of 10.

Introduction to Arienai
By the age of 12, Yasaka had already undertaken a wide range of missions, and had become highly skilled in combat. He had awakened his Sharingan sometime during this age in an unknown event, though it is likely that this was merely due to the stress of a particular mission, due to the fact that Yasaka has never mentioned otherwise. Having become a very proficient user of both Fire Release and Wind Release, he had become very confident in his abilities, but slightly arrogant. However, he was oblivious to the fact that he was constantly under the watch of certain shinobi who had taken an interest in his fast growth and abilities.

While out on a mission in the Land of Lightning's mountains alone, Yasaka was suddenly approached by a figure cloaked in black, who was actually the shinobi known as Arienai in disguise. He was initially startled by the man's arrival, and was quick to question what he was up to. The man simply laughed, and stated that he had something important for Yasaka to hear. The child reluctantly listened on, suspicious of the cloaked figure. When the man asked him about his thoughts on the "ignorance" plaguing the shinobi world, Yasaka was quick to dismiss him. The figure taunted him by stating that he and his loved ones would have to endure a great tragedy soon if he was not aware of the "true nature of mankind", which caused Yasaka to angrily rush towards him, attacking with Wind Release: Vacuum Serial Waves. He was surprised when the man easily dodged, and simply trapped him in place using Crystal Release: Crystal Encampment Wall. He was then forced to listen to the figure's following lecture about the topic, and the foolishness of modern shinobi. The figure stated that it would eventually return to see Yasaka's progress, and vanished while simultaneously releasing him. Not knowing what to make of the event, Yasaka simply carried on with his mission and went home afterwards, with the figure's words continuing to dwell in his subconscious.

Attack on the Lightning Daimyō
At the age of 14, Yasaka had already been promoted to the rank of Jōnin, and had come to be considered a truly gifted shinobi. However, he felt that life had been quiet for him, and eerily so. Passing the time by either training or playing music on his violin, he decided that he was at peace for the time being. He had been assigned to what he thought would be a quiet mission, which required him to temporarily guard the Lightning Daimyō for reasons which were not disclosed to him. In reality, Arienai had influenced the selection of this mission from the sidelines to manipulate Yasaka into his way of thinking. The peace would soon become interrupted due to the events in which the organization Igirisu, led by Sawaru (who had actually been placed the effects of Arienai's Kotoamatsukami several years prior), would attempt to weaken the Land of Lightning enough to begin a takeover via the elimination of several political figures, though this was plan had been set up to fail by Arienai as well. One of these targets would be the Daimyō himself.

When Igirisu members were dispatched to deal with the Daimyō, Yasaka was quick to come to his defense. A short fight occurred, with Yasaka victorious, having used his two-tomoe Sharingan and Fire Release capabilities to take his opponents down with ease. When he questioned them why they had attacked, they told him that Sawaru had sent them to bring about his rise to power. Intensely horrified by their words, he demanded to know of his father's whereabouts. When they told him, he brought them to a swift end, and departed as others arrived to take the Daimyō to a safer area. He would soon arrive at the hideout which his father was using to conduct the operation, and reflected back upon his father's seemingly-constant absence, and came to the revelation that he was nothing more than a corrupt politician. Yasaka infiltrated the hideout, ruthlessly slaying all of the shinobi within it. When the inevitable meeting with his father occurred in the center of the compound, the two simply stared at one another for several moments. The silence was broken when Yasaka verbally assaulted the man for his intentions. Sawaru stated that Yasaka still knew nothing of how the world worked. He then attempted to kill his son with Chidori Sharp Spear, though Yasaka dodged and retorted with Fire Release: Phoenix Sage Flower Nail Crimson. His father avoided, and began a steady barrage of Taijutsu and Kenjutsu maneuvers to Yasaka, who failed to intercept a few. Though his father kept the upper hand throughout the first portion of the fight and eventually began using Hasamibujin to back Yasaka into a "corner", his father's taunts eventually pressured him into fighting back with a vicious chain of Fire Release techniques, and his father eventually retreated, leaving behind his weapon. Yasaka pursued, and was led to their home, where he encountered Sawaru holding his mother and Etsuko captive with a kunai to each of their necks. The man stated that he would teach His son a lesson about the world the hard way, and slit both of their throats. Just as he had finished the deed, Yasaka had cleaved him into two halves with the same weapon he attacked with earlier, unlocking his Mangekyō Sharingan in the process. As he stood over the scene, he declared that he truly hated who his father, and all those ever like him were (and still are), and left as a single tear escaped from his eye.

The same figure that Yasaka had met years ago would soon reveal himself again to the boy days later, questioning what he would do next. Yasaka admitted that he didn't know, and watched as the figure nodded. Revealing that his name was Arienai, he offered Yasaka a place as one of his subordinates. When Yasaka hesitated to answer, Arienai asked why, although he seemed to already know the answer. Yasaka then told the man about what Sawaru had said about the world, prompting Arienai to state that people like him couldn't cause trouble in a world where all the nations were united under one leader, and that he intended to be that leader. He then questioned Yasaka again, and the youth was quick to say yes. The two then travelled off to Ningenyomi, with Arienai proclaiming that he would train Yasaka into a shinobi strong enough to prevent "tragedies" such as his own which had taken place. The whole time, he was unaware of the fact that Arienai himself had caused all this just to get Yasaka to join him.

Ningenyomi and Nishikari's Beginning
When Arienai, now accompanied by Yasaka, had first returned to Ningenyomi in the Land of Lightning, things were rather quiet and uneventful at first. The man gave Yasaka a place to stay within the large hideout, which he was grateful for. He seemed to speak with Arienai daily, seeing a great source of wisdom and intelligence in him. In these many conversations, he listened to Arienai's statements and thoughts, though he did not understand the meaning of most of his lengthy lectures. When Yasaka inquired about the training which Arienai had mentioned before, his reply was that he would not be trained until he came to terms with the information presented to him. Although he didn't show it, the conditions of the agreement frustrated him, as he struggled to piece Arienai's words together. As time went on, he thought deeply about what Arienai had already taught him, searching through his own memories for the answers he needed to his many questions. Unfortunately for him, the answers did not come as soon as he had hoped. Over a year had gone by without Yasaka and Arienai beginning the training, and during that year Yasaka simply trained his chakra control on his own while performing the tasks that Arienai required of him, such as assassinations or the capture of enemy shinobi. These many tasks caused him to travel to the furthest ends of of the world often, ranging from the Land of Water to the Land of Earth. Each of these tasks had been specifically selected by Arienai to help Yasaka realize the "atrocious habits of man". Although it is unknown what the tasks consisted of entirely, they seemed to have a psychological effect on Yasaka.

As planned, the assigned missions had changed the way Yasaka thought about the world. He had to deal with truly vile shinobi, most of which beyond retribution for the acts they had committed. Slowly, he came to agree with Arienai, and declared to himself that mankind as a whole couldn't be trusted with freedom, and that a constant watching eye was required to keep things stable. Noting that the only way to do this was to unite the shinobi world into a single regime, he returned to Arienai after his revelation. When Arienai asked the boy what he had learned, Yasaka told him all the answers that he wished to hear. Pleased, Arienai told him that he was ready to assist him in the first phase of his plans, the creation of Nishikari. It was then that Yasaka was tasked with gathering shinobi for Arienai's cause, so he would depart from Ningenyomi often to seek shinobi who were willing to join them. In the process, he would have to kill many shinobi as well.

When he was not recruiting, he would train with Arienai. This continued on for years, and he eventually beame capable of using all three of his chakra affinities. Yasaka had also become highly skilled in Kenjutsu. As he slowly learned how to properly use his Mangekyō Sharingan without overrelying on it, he would also become capable of using Amaterasu and Tsukuyomi to their maximum tactical potential. Arienai, who watched his progress constantly, stated that Yasaka was strengthening very quickly, and that he had picked an excellent subordinate. For the next couple years, the two continued to operate in secrecy.

Destruction of Jakazan Owari
By the time Yasaka had reached his sixteenth year, Arienai had turned him into a devastatingly powerful shinobi for his age. Not only had his skills improved, he gained several new ones along the way, and had learned how to be an effective strategist. These skills would soon be put to the test, when Arienai's men alerted him of a conflicting presence in the area that had discovered them. This presence was in fact Jakazan Owari, which had recently fallen victim to a complete absence of leadership and was becoming unstable. As a result, they were desperate for power, and would begin to meddle with the fledging Nishikari in order to obtain it. The first signs were that some of Nishikari's shinobi failed to return from their missions, and had gone missing. Arienai had immediately known that he would soon be able to assess Yasaka's abilities.

Arienai then informed Yasaka of the looming threat to his plan, stating that he had known a few things about Jakazan Owari, and that it was highly likely that they would attempt to completely overtake Ningenyomi. The man's apprentice was quick to volunteer to take down what remained of the organization, much to Arienai's liking. However, Arienai stated that he would accompany him with a small team of subordinates. Yasaka showed concern for the hideout, before Arienai reassured him that it would be safe. The group then departed, heading off to Jakazan Owari's northern hideout, which had been declared as the first target. It would be the first time Yasaka went into a true battle with a gunbai, which he had strapped to his back.

When they arrived on the perimeter of the towering base, Areinai would encase the entire structure in a shell which prevented escape using Crystal Release: Jade Crystal Labyrinth Technique. He left a small passage that led into the base from a point near it's spire, directing the group to head inside. One by one, Yasaka and the others advanced up the side of the crystallized tower and began the invasion. They slew all the opposition whom they came into contact with, allowing Yasaka to showcase his improved Wind Release skills while utilizing his gunbai. They also recovered large amounts of information that the organization had gathered, including a journal left behind by Kamaitachi Tetsugaku. Rigging the base with several explosive tags, they evacuated with a select few shinobi who had surrendered, and demolished the structure as Arienai released his technique. Later, as the group rested, Yasaka would read through the journal, amazed by the stories of it's former owner. He kept it hidden from Arienai, and it would remain in his possession for several weeks. During this time, he began to admire Kamaitachi more and more, eventually developing a desire to find out where the man had gone off to.

Noting that the southern base had already been destroyed, Arienai took the group back to Ningenyomi, where they took time to recuperate before heading out westward and imprisoned a large majority of the captured shinobi. During this time, Yasaka developed a friendship with the captive Nui Niyari, convincing Arienai to release him. Yasaka would make the shinobi his personal medic, who accompanied them in destroying the eastern base, which was bombarded by several Fire Release techniques at once; among them, the several "bullets" of fire which Yasaka produced using Fire Release: Glare of the Masked Messiah. The many shinobi went on to travel to the Land of Wind, facing a larger amount of opposition than the last two bases. However, with Arienai's Sage Arts and Yasaka's Susanoo, the amassed defense was taken down just as quickly. After obliterating this base as well, they moved on to El Dorado, which was ruled over by Matsu Aizou at the time. They encountered seemingly endless hordes of Jakazan Owari's shinobi, persevering through durable defenses as they ascended the mountain which El Dorado was located on. Although many lives were lost, they managed to secure the exterior. Arienai directed Yasaka to continue on through the interior with Nui, in order to eliminate the compound's overseer, and the leader of the entire organization in general.

As Yasaka made his way through the compound with Nui, slaying many in the process, he would eventually arrive in the inner sanctum, where Matsu had been waiting for him. The elder expressed great loathing in Yasaka's actions, stating that Nishikari had no right to attack. Yasaka only laughed and shook his head, retorting back that it was Jakazan Owari that had "challenged" Arienai's capabilities. The elder attacked in a fury, though Yasaka quickly incinerated him with Amaterasu and purged the hideout of the remaining shinobi. He then sent Nui to notify Arienai that Jakazan Owari was no more, and when Arienai himself entered the inner sanctum, he directed Yasaka to return to Ningenyomi and await further instructions, while he finished his business in El Dorado. Arienai noted that Yasaka was becoming a perfect weapon.

Personality
Though a bit of a depressing fellow due to the blank expression he usually displays, Yasaka is calm and calculated both on the battlefield and during everyday life, and is overall a very intelligent individual. He is quite level-headed, always remaining focused on the task at hand and never allowing trivial matters to disrupt him, while remaining composed and stern; even when the possibility of death is present. However, Yasaka is equally as laid-back as he is focused. It is not uncommon for him to joke around and toy with his opponents in a fight, approaching it much like a game with his sarcastic sense of humor. At the same time, he has little tolerance for childish or immature remarks.

Yasaka could be considered a strict perfectionist, and perhaps even narcissistic in some ways. Having adopted Arienai's philosophy, one of his main concerns is his own power and control over others, in the belief that his actions are for the greater good. While this has led to some rather noble traits such as his practically unbreakable determination and his skill as a strategist, Yasaka's stubbornness towards his goal has led to him being very manipulative of others (including towards close friends). Though he does not disregard their own feelings and well-being, he is reluctant to allow loss or misfortune to himself in their place. Yasaka views betrayal of his trust as a serious matter, becomes easily perturbed by such acts, and would not hesitate to verbally or physically attack anyone whom he has enough evidence to mark as a traitor. He is capable of being rather blunt and rude to people, as well as completely apathetic and "brutally honest" towards them. On the other hand, he is capable of being supportive and positive when needed to be. He is also a music lover, and tends to hum often when at peace. Although he does not speak about it often, Yasaka has stated that he is homosexual, and feels no need to hide it; rather, he is proud of it.

Appearance
Yasaka is a young male with purple eyes and long black hair, which is kept loose and reaches down to his chest half the time, covering the left side of his face in the process unless tied into a ponytail the other half of the time. A few strands stray away, draping down the front of his face. His skin is quite pale, though the results of Arienai's experimentation to heighten his resistance to poisons are to blame for this. Yasaka possesses an androgynous appearance, and he has been mistaken for a female on some occasions by shinobi under Arienai's command, and others; he is slightly shorter than most males, has a more feminine and slender frame than most, and couldn't be considered muscular or robust at all. He sometimes wears a deep blue color of eyeshadow as well, further augmenting his aforementioned traits. This particular aspect of his appearance has contributed to him gaining the nickname, during his time in the village.

Yasaka's first outfit during his younger days was rather unorthodox for a shinobi. He wore a dark, navy blue kimono-like garment with black trimmings, which extended down to his knees. The right half had a shorter sleeve than the rest, and hung off of his shoulder. The garment was tied by a white belt, and black pants were worn under it. A long white cloak which reached to the ground was worn over, almost shielding the clothes under it from view completely.

Upon joining Arienai, he discarded this look entirely, and adorned the clothes which he wears in the present time. This consists of a simple black cloak with a fur-trimmed hood always kept up, and slight rips and tears at the ends of the sleeves. The crest of the Uchiha Clan is printed upon the back of the cloak. Under this, he wore a sleeveless black shirt with black pants, as well as a senbon holster on each leg. A large black Gunbai with navy blue trimmings is worn on his back, held by a strap across his chest. A gold earring is worn on each ear (they are usually obscured by his hair), while a golden pendant and an Amegakure forehead protector are usually worn around his neck, though they are usually kept hidden by his cloak. In recent times, he has begun to substitute this cloak for the standard Akatsuki one: a long, black garment with a high collar, red lining on the inside, and the trademark red cloud patterns of the organization. He has altered it slightly to include a similar hood to his regular cloak, excluding the white fur.

Abilities
Over the years, Yasaka's determination and talents have allowed him to become a powerful individual worthy of recognition from many. Although many would not expect it due to his rather unthreatening appearance, Yasaka was indeed a child prodigy who excelled in almost all of the academy's classes, making perfect grades at nearly every turn. Astonishing both his instructors and his fellow students alike, the boy eventually went on to graduate from the program in a quick seven months to be promoted to a Genin, and reaching up into higher classifications of Chūnin, and for a while Jōnin years later. As Yasaka's abilities improved and his life underwent many twists, the shinobi Arienai took him under his wing, training the boy many of the techniques and fighting styles which would eventually become a "second language" to be used on the battlefield to him.

At the age of 16, Yasaka was already well-versed in the ways and lifestyle of a shinobi, showcasing skills in several different areas. Nothing short of a genius, he would continue to impress others as he and Arienai eliminated what remained of Jakazan Owari. Later, with the teachings from Kamaitachi Tetsugaku, Yasaka would gradually reach into a new tier he had never dreamed of achieving, going from a typical Uchiha to a true rising presence which had made a name for itself.

Bukijutsu
Yasaka's prowess using ninja tools is easily recognizable, as it has been from a very young age. From setting up traps or the heat of direct combat, he has shown to be able to use tools tactically and very effectively. The weapons which he uses the most often are senbon; he has stated that they accommodate his preferred methods of combat well, going especially well with his Wind Release affinity. Using the Shadow Senbon technique where necessary, he may easily fool an opponent into taking a direct hit. When using wire strings, his bukijutsu prowess truly shines; he may manipulate weapons in midair to form successful strategies, and even set up for frightening techniques using fire. Yasaka will sometimes use the gunbai usually worn on his back in battle, both to shield against minor attacks, and to launch his own Wind Release techniques.

Kenjutsu
Since his days as a student of Kumogakure's academy, Yasaka has displayed a high level of skill as a swordsman. As kenjutsu is an encouraged art in the village, it was only natural for him to become one, though it quickly became clear to others that he wasn't simply "average". When he later stole his father's nodachi Hasamibujin, Arienai saw that it was fitting for him to learn kenjutsu, and arranged for his subordinates to train with him often. Yasaka was never bested by a single one of them, eventually becoming adept in Iaidō during the constant traveling required of him by Arienai. It is unknown if Yasaka has ever traveled to the Land of Iron, however.

Yasaka has made a slight habit of primarily utilizing a reverse grip while dual-wielding blades, although it could also be considered a part of his own personal style, which takes after his taijutsu style as well. His strikes can be blindingly fast at times from the perspective of those with normal eyes, leaving little time for one to evade or counter them. He is also quite fond of channeling his wind chakra down the length of the blades, increasing their cutting power dramatically and his effectiveness in close combat as a result.

Yarijutsu
While less pronounced than his kenjutsu skills, Yasaka has shown himself to be capable of utilizing a spear effectively in a fight, namely Iyasu. Only relying on these skills when forced to attack from a slightly further range, or when kenjutsu would simply be at a severe disadvantage, it is rare for him to actually use this art. due to this, his abilities as a spearman are only slightly above average.

Summoning Technique
Although unconfirmed, there is enough information to assume that Yasaka was first taught how to use the Summoning Technique by Arienai early on in their training together. Eventually going on to make good use of it, he later signed a blood contract that would enable him to summon forth vultures to battle alongside him. These avian companions may range from the size of one's hand to a massive scale large enough for several people to stand on. He commonly uses them to perform aerial attacks from above, usually with projectiles empowered by Wind Release.

When Yasaka first obtained the contract, he was only able to summon smaller vultures, which were useful for sending messages or diversifying his genjutsu techniques. As he trained his chakra control, his capabilities rose as well, and larger vultures such as those usable in combat became his trusted allies as well. Holding a deep friendship with each of his summons, Yasaka and the intelligent birds collaborate on strategies and techniques in battle often.

Nature Transformation
Over the course of his life so far, Yasaka has become proficient in several different elements. This has allowed him to use a large number of techniques, and with his Sharingan's technique copying abilities to thank, they span over five of the basic chakra natures. Due to his Uchiha heritage, Yasaka has a natural affinity for Fire Release. After later discovering that he could also use Wind Release, and eventually Water Release, his arsenal became rather varied, providing him with what he needed to take on many different types of opponents. He may also form hand seals at speeds very difficult to follow for others, even using one-handed seals at times.

Yasaka was only 6 years old, and still in his fifth month of teachings in the academy when his affinity towards Fire Release was discovered. From this it could be interpreted that his skills in this specific nature are stronger than they are in his other usable ones, as he became capable of using techniques far above his level by the time he graduated, such as Fire Release: Phoenix Sage Fire Technique. Because it was unusual for freshly-promoted Genin to be able to use elemental techniques so early on, Yasaka surprised many with his growth rate. As his chakra control and stamina developed, this growth rate would quicken; around the time he was assigned the rank of Chūnin, his Fire Release skills progressed to the point where he could produce Fire Release: Great Dragon Fire Technique. With Arienai's training, the creation of even stronger techniques such as Fire Release: Glare of the Masked Messiah and Fire Release: Daybreak had established Yasaka as a master of the chakra nature. He would use it to increase the deadliness of his weapons as well, though overall, it remains his favored method of long-ranged combat.

A few years after he started using Fire Release, his abilities to use Water Release and Wind Release were also discovered. Yasaka first used the latter of the two at age 10, though he lack the proper training in order to use it offensively. It was only until his first encounter with Arienai that he could properly assault a foe with jutsu such as Wind Release: Vacuum Serial Waves, though his limits were surpassed remarkably fast. He would begin to channel Wind Release chakra through the length of his swords, even using it to propel himself at high speeds via Wind Release: Assassin’s Rush. When Yasaka became a Jōnin, his horizons broadened, allowing him to use the nature to it's fullest extent in mid-ranged combat. When Arienai officially began to train him, his third natural affinity, Water Release, became usable. He has not been witnessed attacking with it as often as the others, preferring to use it more supplementary, one case being the Hiding in Mist Technique. However, this is not the full extent of his ability to use Water Release, as seen in Water Release: Samsara Surge Technique, which is one of his higher-end original techniques. Through various battles, Yasaka has also been given the opportunities to copy Lightning Release and Earth Release techniques, the latter being a result of an encounter and a short fight with a shinobi named Rikiryou.

After unlocking his Mangekyo Sharingan, Yasaka gained access to a more advanced form of Fire Release known as Blaze Release. It allowed him to further manipulate the inextinguishable black flames of Amaterasu in order to use them more tactically. He may form strong defenses with Blaze Release: Kagutsuchi, or incredibly powerful, though just as draining assaults through Blaze Release: Ōhoyamatsumi, which has been regarded as a jutsu he admired so much that he named it after his alias. With Kamaitachi Tetsugaku's DNA, Yasaka has also gained the ability to combine his wind and fire chakra natures to form Ash Release. His adaptations to the options granted to him in battle were fast, as he has displayed a level of prowess with this Kekkei Genkai far beyond that of what Kamaitachi could achieve, an example of this being that he could use Ash Release: Blaze of the War God to annihilate opponents with ease, while Kamaitachi had difficulty controlling it.

Taijutsu
While his body is much more fragile than the physiques of most others, and generally unsuited for Taijutsu and close combat, Yasaka has continuously trained for years in the art due to his determination and willpower to change the world. His high speed, agility, and flexibility have allowed him to perform some rather deadly maneuvers, most of which being a part of the fighting style which he created along with Arienai's assistance, Heavenly Fist. This style allows Yasaka to take advantage of his high dexterity, landing several swift blows in a short time in a manner similar to that of the Gentle Fist in appearance; those without the Sharingan would have trouble keeping up with his movements.

However, his endurance and stamina are still lacking. This is a major hindrance to him, as a hard blow would take more out of him than it normally would for others. This has forced Yasaka to rely more on evasion and his alert reflexes than blocking or intercepting most attacks. As his physical strength also leaves much to be desired, Yasaka is incapable of truly dealing devastating blows.

Nintaijutsu
Though not an expert, Yasaka is neither a stranger to nintaijutsu, and began to incorporate it into his arsenal as soon as he became capable of using Ash Release. His nintaijutsu maneuvers begin with him using Ash Release Armor, covering him in a thick grey blazing shroud which is intensely hot. The shroud augments his already superb dexterity, allowing Yasaka to move at incredibly fast speeds, and perform maneuvers which he wouldn't have been able to do prior. Unlike most other styles of nintaijutsu however, Ash Release nintaijutsu fails to alter the user's actual strength in any way. To remedy this, Yasaka relies on the style which has become known as Ashen Fist. This style focuses much less on landing harsh blows; instead, making use of the shroud itself to deliver most of the damage.

Sharingan
As a distantly-related member of the Uchiha Clan, Yasaka possesses the ability to activate an infamous dōjutsu known across the shinobi world, the Sharingan. He had awakened it during a particularly stressful mission around the time he was promoted to Chūnin at the age of 12. Initially, he had one tomoe in each eye. However, he would increase it to two with continued training, and eventually three during a battle with his father, Sawaru. Having brought his Sharingan to full maturity at that point, he would become capable of using each of the abilities normally granted to one with it. These included analyzing the movements of an opponent to the point where their next move could be predicted instantaneously, copying a witnessed technique, and launching ocular genjutsu.

Due to the amount of time in which he constantly trained his eyes, the Sharingan has a very small effect on his chakra levels, to the point where it could be considered negligible. This remains true, even in long and tedious fights against multiple opponents. He dislikes relying too much on the Sharingan, but he has been witnessed having it active constantly on rare occasions. His genjutsu abilities using the Sharingan have been noted to be on a high-level, allowing him to temporarily hypnotize someone, paralyze a foe, or replay his own memories to another.

Mangekyō Sharingan
Yasaka awakened his Mangekyō Sharingan shortly after the battle with Sawaru, where he witnessed the man slay Etsuko and his mother, only for him to slay his father seconds after. Unlike most, who awaken a Mangekyō Sharingan with a black design and red background, Yasaka's eyes take on an inverted pattern, which consists of a red pinwheel surrounded by three red triangular shapes. Finally, a single red oval is located where each triangular structure meets an "arm" of the pinwheel. The background of his eyes are also slightly lighter than most would expect, becoming a dark shade of grey rather than truly black. Customary of the dōjutsu, Yasaka's Mangekyō Sharingan damages and gradually reduces his eyesight by a very small amount every time he uses it, causing him to experience great pain and extreme fatigue as well as causing eye bleeding with each use.

Each eye of his Mangekyō Sharingan contains a specific technique. The first of Yasaka's granted abilities is Tsukuyomi, which is given to him by the left eye. Requiring eye contact with the desired target to function, it is a very powerful genjutsu which is capable of trapping an opponent within an illusion that Yasaka may freely control. The full extent of his manipulation over the illusion is said to allow him to make it seem like days in an opponent's mind, while the torturous event would have only been a single moment in reality. By the time Tsukuyomi ends, it's victim is usually left in a state of exhaustion, or unconsciousness. The ability granted to Yasaka through his right eye is Amaterasu, a technique that allows him to incinerate anything within his direct line of sight with inextinguishable black flames; they are said to be able to burn anything, including fire itself. Using the Blaze Release chakra nature, Yasaka may further manipulate these flames, or extinguish them at will.

The final technique granted to him by his Mangekyō Sharingan is Susanoo, the, which takes root in both of his eyes. Through it's use, he may form a large ethereal warrior around him, serving as an immensely durable defense. So far, Yasaka has only been able to manifest an imperfect, though fully-sized Susanoo. Separate parts of it, such as it's ribcage, may also be formed on their own at once; Yasaka may even form several pairs of arms on their own. Using it as a catalyst, Yasaka can also use a technique which he even shares a name with, Yasaka Magatama, a long-ranged attack that ends with a rather large explosion upon contact with something. Susanoo has the greatest strain on him of the three techniques granted to him by his Mangekyō Sharingan, as it's overuse may cause him to violently cough up blood. Yasaka's Susanoo takes on a blue-green color, and bears a slight resemblance to a bull.

Chakra Prowess
Yasaka is physically weaker than most. However, like most Uchihas, Yasaka still possesses powerful chakra. His reserves are very large, due to him having put constant effort into strengthening himself in order to overcome his weaknesses. In the academy, instructors mentioned that his chakra control was far above what was expected of an academy student, due to his ability to use Fire Release so early on. His reserves would continue to grow with age, eventually allowing him to use several rather taxing techniques in succession before showing signs of fatigue. Due to extensive training of his Sharingan, Yasaka may keep it active for long periods of time if desired, even near-constantly at times; Yasaka owes this to his dormant Senju blood. Although he does not possess Wood Release, the DNA of this clan does provide him with increased stamina. Not only are his reserves strong, but he is also sensitive to other sources of chakra, making him an exceptional Sensor-nin.

Intelligence
Yasaka's most reliable ability would be his quick thought process, as he has proven to be very analytical and perceptive, both in and out of combat. While in the academy, he earned near-perfect scores, signifying his status as a genius shinobi. On one occasion in particular, with nothing more than a small amount of information about a technique and the context of the battle, he figured out it's inner workings and quickly outsmarted his opponent. He is a very good manipulator, able to persuade or pressure others into doing the tasks he desires of them; one may infer that he is a good liar as well. Remaining calm most of the time, Yasaka always thinks out the circumstances of a situation before acting. He is an adept leader and a well-versed strategist, making sure to pay attention to every single detail of an opponent's moves and techniques to develop a suitable countering tactic. The raw knowledge gained from his time in Nishikari, combined with the information looted from Jakazan Owari, both have set Yasaka on the path to becoming a walking library as well, though he is not lacking as a deep, philosophical thinker either.

Other Skills
Yasaka has displayed some knowledge in fūinjutsu, having developed a method allowing him to implant Tsukuyomi into the Sharingan of another person, and having learned a similar method for Amaterasu. Arienai's experimentation has granted him heightened resistance to poisons, as well as an increased tolerance to pain. Yasaka's enhanced hearing allows him to use Silent Killing, a fighting style based purely on navigating using sound.
