Yuki Akatsui

Yuki Akatsui is the seventh child of Taiko and Judith Akatsui. He was raised as a doctor but was then sent to join the Cheka police, only to later become a Pro Bounty Hunter.

Appearance
Yuki is an average height, fairly muscular teenager with big green eyes and curly brown hair. He wears a long sleeve black and white striped shirt, with a variation of dark colored shirts over it, and black pants.

In the Barracks Yuki wore the standard Cheka outfit, tying the headband around his left shoulder. He chose his outfit to be two sizes too big, allowing for more concealment, and tucked in his pant legs into his boots.

During raids as a Bounty Hunter, Yuki wears the outfit designed for his division, which consists of a collared white sweater with a baggy black hoodie over it, and black pants. Both his hoodie and pants have a single green stripe running through the middle that represents his role in the division. He switches between wearing the hoodie up and down depending on the situation.

Personality
Yuki is initially introduced as a very selfish narcissist who places great emphasis on material wealth. Despite his assertions that he is only in the military because he was forced to, he eventually reveals to Zed and Knox that he willingly joined the Barracks to learn to fight. He believes that all things in the world (lives, dreams, etc.) can be earned through combat and that by joining the Cheka he will become a better fighter. Due to his first spat with Zed, it seems that he has a sensitivity for those who don’t take him seriously or treat him with disrespect. His real priorities seem to be his friends first, then his combat abilities, then everything after.

Despite being brash and self-centered, Yuki has an inferiority complex and questions every move he makes. He keeps these traits incredibly well hidden and few people realize them, which in turn worsens them. In battle, he often balks when he could easily attack as he can’t decide what to do in time. This leads Zed and Knox to force him to take on a more passive role in combat, which he despises. After realizing what friendship truly is, Yuki believes that he should help his friends over any other goal, but has trouble coming to terms with this when it actually matters, and often saves himself over his allies in times of need. He feels extreme remorse after these events occur, but can’t bring himself to change. At the height of the Killjoy Arc, Yuki is able to overcome his fear and help his teammates instead of retreating, fatally injuring him in the process. After this event, Yuki proceeds to slowly stop doubting his actions and trusting his instincts.

Background
Yuki was born as the seventh and youngest child of a family of known doctors, the Akatsuis. His parents, Taiko and Judith Akatsui, wished for all their children to follow in the medical field. From a young age, Yuki showed promise as a doctor and had his Keiyaku chosen to be a syringe.

Around the age of 10, Yuki started showing interest in combat and distancing himself from healthcare, angering his parents. They locked him in his room and forced him to do nothing but study for three years, and after frequent escapes and flees his parents decided to send him to the Barracks to become a soldier, in hopes that Yuki would be scarred by the horrors of war and return to medicine.

Equipment
Satchel: Yuki carries a black satchel everywhere he goes, containing medical items and miscellaneous objects.

Throwing knives: Yuki keeps five throwing knives around his belt and one in his right shoe for combat purposes.

Abilities & Powers
As an Akatsui, Pro Bounty Hunter and retired Cheka soldier, Yuki holds authority over most people. He achieved the rank of Notorious in the Fight Clubs. During his training as a soldier, he was praised for his analytical skills and extensive knowledge of the world due to his studies. In battle, Yuki is often considered a dirty fighter who doesn’t show any of his cards unless he has to. His instincts are incredibly accurate and often give him the upper hand in combat, if he chooses to listen to them.

Keiyaku
Yuki’s Keiyaku is a medical syringe filled with O- blood. The most practical use for this Keiyaku is in the medical field, however Yuki uses it both for medicinal purposes and in combat.

Kotsu
Yuki is nearly 100% a Jotai user, which means he can change the makeup of his Keiyaku. Because he studied medicine and botany as a child, Yuki is able to convert his Keiyaku to any blood type, as well as anaesthetics and most medicinal drugs.

Ability - Fuck Your Mental - Jotai

Yuki throws his syringe towards the direction of his opponent, then converts it to sleep anaesthetic and throws his knives through it. If the knives connect with his opponent, they will inject sleep anaesthetic into their bloodstream, effectively knocking them out.

Goals/Motivation
Yuki is primarily motivated by spite towards his family. After being excommed from the Akatsui family, Yuki decided that he wanted to make more money than any of his siblings through an unorthodox profession, which became combat.
