Template:Koyoichi Alter

Koyoichi Alter is an altered human, the result of one of Yūmei Luenah's many heinous experiments. Incoincidentally, he was modeled after Koyoichi Ayime.

Tenryūji
Koyoichi Alter was developed soon after Koyoichi Ayime perished in Konohagakure by Yūmei Luenah. Several months were spent perfecting him, using a high ranking member of the ANBU as a medium and a fair amount of Yliaster to create a body even better than the original. He was then released from his incubator.

Personality
Koyoichi is sarcastic and cynical. His hardened demeanor is assisted by a complex and dark personality which reveals rare occurrences of compassion and unfolds throughout the story. Though skilled with ranged weapons, he can hold his own in hand-to-hand combat. He considers selfless idealism's to be weak and delusional, identifying the mentality of "wanting to save and protect everyone" as being naïve and quite frankly impossible. He holds a distinct hatred towards Konohagakure, particularly because it resulted in the death of his original, and additionally instigated his own creation.

Appearance
Koyoichi is a fairly muscular man with relatively-grey iris' and white hair. He has sightly tanned skin of which is only noticeable when he's in a shaded area, leading to some to refer to him as a hidden beauty, disregarding his cold personality. He has black plating lining up the sides of his neck and cheeks composed of Yliaster.

He wears a black plated-torso protecting him from projectiles like kunai and shuriken, which would be deflected upon impact no matter the speed of which they're thrown unless they're reinforced with a side-effect like elemental chakra, as his armor is stored with chakra he's stored over a decade of which continually runs through white-strips on its surface. Notably it possess high resistance to slash-weapons, although leaves him susceptible to pierce-based stab wounds. Over this Koyoichi wears a red trench coat which covers most of his torso and most of his leg area, although it possesses little defensive capabilities. He wears black cloth trousers, strapped with black belts as to compress their linings together and enable him more proficient maneuverability.

[Custom] Summoning: Lightning Blade Creation
What distinguishes Koyoichi's version from the original is that he has a mass collection stored within his miniature 'treasury', whereas the typical use of this technique is to summon only the most basic ninja tools such as shuriken and fūma shuriken. A compiled list of [unique] weapons is displayed below:

Piasudoūmu
The blade of the sword coils into a spiral that can penetrate any target by creating a twisting distortion in space via chakra channelling, a simply action due to its drill-augmented structure. Due to its small size and fairly-round shape, Koyoichi prefers to fire it as a projectile where its penetration-prowess is tripled as it's physically infused with chakra; upon impact though it is powerful enough to pierce through practically any chakra-reliant defense (excluding the Yata Mirror) and most of Zokuseitsuki Shīrudo's layers. Unless the target has an unfathomable-quality physical defense their entire being would be destroyed in an instant; the area surrounding the victim would also be engulfed in flames upon the projectile's impact as it scatters as the blade reforms.

Ionka Haretsu
Koyoichi doesn't use it as a sword, but rather prefers to project and use it as a projectile by firing it from his bow. It is a pitch-black weapon, with a few small edges coiling around the thin core, spiraling around it and somewhat curving outward. Once fired, it is engulfed in chakra enveloping it in what appears to be a red light (which is really a combustion of regular chakra) that reaches speeds of Mach 10 on the most direct path to its target, and it will continue to pursue the target, even if parried, repulsed, or avoided, as long as the shooter keeps aiming at the target. While it is normally impossible to change targets after firing, he is able adjust for such possibilities and have a single path be capable of striking two enemies. He can shoot it over five times in a row, and he applies more chakra to charge the shot each time. The second shot has a charging interval of twenty seconds, and the time increases after he places more power into it, with twenty-five seconds for the third and thirty for the fourth. He can further adjust and charge the shot by taking five more seconds. It is fast enough to reach its target four kilometers away in less than a second, and it has enough force to stir the air and cause the bridge to rattle.

Kanshou & Bakuya
They are "married" twin falchions representing yin and yang, forged by Koyoichi as an adolescent. They are his favored weapons to utilize in battle, having become his symbols after wielding up to the present. He personally finds them to be extremely captivating and beautiful the weapons easily suiting his natural style of fighting. They are identical in shape with the only difference being their color. Bakuya, the black Yang falchion, is covered in a hexagonal pattern, and Kanshou, the white Yin falchion, has less of the shine of a polished metal in its ore than it has the haze of a cloud. Their quality as swords is high due to being made with the best materials at the disposal of Koyoichi with the quality of the grips, both of which are quite big and heavy, are more important than their ornamental value. The main ability of the blades is their strong bond with each other, which not only allows them to attract each other, but it is also said they will return their owner even if events cause them to be lost. If one is thrown while the other is held, the thrown falchion will return to the wielder much like a boomerang. This works well with Koyoichi's customized summoning ability, allowing an already summoned sword to identify a newly-summoned as its partner falchion. When both are wielded, reflectively so is the combat-prowess of Koyoichi - flawless. If wished, Koyoichi may channel his chakra into the hilt of the falchions as opposed to their blades, causing them to notably extend to almost twice their original size and bear a more menacing design. While although the enhanced twin swords don't possess any special abilities on their own, when infused with chakra the range of their potential strikes is doubled in length, the chakra itself considered an expansion to the blades in that despite their naturally weak physical structure, they become relatively solid and are thus, lethal.

Rho Aias
Rho Aias is a shield taking the form of seven layered barrier with the shape of an iridescent flower with seven petals. Each layer has the defensive power of a fortress wall, the second best defense as it tails behind the first, the Yata Mirror. It is necessary for Koyoichi to provide constant chakra to form the shield, and if it is damaged, he will feel pain and receive damage in accordance. Regardless of the consequences, he uses it as his main defense. This action consumes a significant amount of chakra to maintain, as it takes three times the amount of chakra as a weapon in order to keep it physical, and still leaves his arm damaged afterward. He can also summon it from a distance, although the chakra consumption is increased depending on the range.

Genjutsu
Koyoichi being a user of Projection possesses a keen level of perception, developing within him a high resistance to most Genjutsu, some of which even derived from the Sharingan are rendered null in the wake of his person. While although he possesses a few skills in this field, Koyoichi rarely utilizes them in the scenario where his opponent(s) possess a superior level of mental resistance to the techniques contained within this category in his arsenal.

Kenjutsu
Koyoichi is more than proficient in the arts of kenjutsu, being able to master practically any blade that comes into his possession through tracing, projecting and summoning another's weapon for his own benefit. His favored blades are Kanshou & Bakuya, of which are utilized to dispatch a large amount of opponents in a short timespan, especially when they're strengthened by a layer of chakra.

Ninjutsu
While although he possesses two chakra affinities, Koyoichi lacks the quantity of techniques reliant on the latter, instead manipulating them to strengthen his weapons. The majority of his supplementary techniques lack any depth into their mechanics, thus leaving him weak in the field. He is particularly proficient in nintaijutsu, more so than his original due to possessing Yliaster-empowered limbs which passively increase his physical attributes a great score.

While not being so proficient with elemental ninjutsu, Koyoichi excels with Space-Time Ninjutsu, manipulating the space surrounding himself or his opponent to take an instantaneous advantage over the opposition with the capability of turning the tides of battle with relative ease.
