Koyoichi Ayime

Childhood
Born into a middle-class family and raised as the son of the local blacksmith, little significance could be said about Koyoichi's infancy. Raised at such a meagre age alongside the smithy he could not help but be fascinated by the weapons his parent constructed and repaired simultaneously on a daily basis. His father however was a solemn man, and contempt when faced with deciding the future of his son. Wishing for the latter to seek out a future undoubtedly more broad than residing within the home premises, Koyoichi was sent to the village's ninja academy. Unbeknownst to all the young child possessed a unique gift (of which would later be fabricated into a personal dōjutsu), a product of his superior perceptiveness to his surroundings and in remembering all events leading up to the present, simply an epitome of his mental capacity - to be called Projection.

In secrecy Koyoichi forged his own custom kunai when he should've been studying, equipped with several camouflaged explosive tags and a wire attached to the back, he automatically graduated from the academy when he brutally slew the students in his class with the mechanism, the time of which the activity was conducted still staining the village with the title of "The Village of the Bloody Mist".

While although his son received praise from the village elders due to his bloody-deed, the blacksmith could not live with the shame of fathering such a person, due to being a humble and modest man himself and was additionally against the village's abruptly legislated graduation prerequisite; he committed suicide in front of Koyoichi whilst crafting a peculiar sabre-like blade, causing the latter to develop a cold demeanour.

Adolescence
As he gradually developed into a young man, Koyoichi manufactured a vast collection of weapons in his father's stead whilst simultaneously rejecting missions directly requesting his assistance due to his merciless feat several years back. Particularly he further developed the final blade of the late smith and paired it up with an almost-identical duplicate, save for the colouring design, of which became his signature blades.

Despite having turned down a chain of missions, Koyoichi passed the Chūnin Exams with flying-colours - not only were the twin swords his only mentionable skills; his chakra manipulation enabled him to enhance the individual prowess' of each respectively as to amplify the damage they inflict, as well as the range of which utilizing them could be considered 'effective'.

A year following his promotion to Chūnin, Koyichi was admitted to the rank of Jōnin, the circumstances to which such an action was conducted being his high level of reliability, having completed a high quantity of missions within a small time-frame with his level of success always at its maximum. During this time-span he began to develop a technique depending widely on his superior level of perception and adaptability to memorising all in sight with relative ease.

The Present
Still a Jōnin of Kirigakure, Koyoichi continues to strive for his own personal growth. He has successfully developed a technique capable of manipulating the electrical impulses in his mind into visualizing weapons wielded by another and through his superior smithing skills, conjure an almost-perfect replica of the original, of course depending on its traits and power. Over the years he was on missions, he has collected numerous weapons from his fallen opponents and created a small arsenal of unique items, mostly weapons, of which aid him on a daily basis for [almost] every task imaginable.

Personality
Due to watching his father committing suicide in front of him at a young age, the experience he had to endure impacted his general personality throughout the past onto the present, where his symbolic cold demeanour has further alienated him from the other villagers, as well as his associates. Regardless of this, he maintains a sarcastic side whenever his isn't being predominantly sadistic in both tone and action.

In all he 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 idealisms to be weak and delusional, recognizing the late Kage's mentality of "wanting to save and protect everyone" as naïve and quite frankly impossible.

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 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 armour 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 manoeuvrability.

[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 Zokuseitsuki Shīrudo 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 defence 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 favoured blades are Raitofezā & Dākufezā, 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 does appear however to possess some hand at nintaijutsu, although whilst under the effects of Lightning Release Armour he prefers to wield his blades to take advantage of his increase in acceleration and perception, as well as to decrease the risk of dislocating any bones or limbs.

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.
