Ayatsuji Yukito

A 27 year old young man, considered to be the Most Dangerous Ability User in the country by the japanese government. He works as a detective and is constantly monitored by the Special Division and an agent from said division, Tsujimura Mizuki.

Ayatsuji has a short wavy blond hair and gold eyes. He wears half-rimmed, light-colored sunglasses, a pair of dark gray gloves, and a flat cap. He dons a jacket with a yellow ochre base with a red collar that he usually drapes over a white shirt with a vermilion-based checkered border and a gray knit vest. He also wears dull orange checkered knickerbocker pants and beige boots. He usually carries on his person a Japanese smoking pipe.

Ayatsuji appears as a cold and emotionless man. He is considered to be fairly odd and detached, as he has a basement full of dolls. Beneath his calculating and snide exterior, he appears to have a kind side to those he forgives, such as keeping a cat and loving it. He is not talkative unless in regard of insulting someone, and tends to make snide remarks and chide others for their lack of understanding. Ayatsuji can be rather expressive and playful, doing silly gestures such as imitating a dog, calling them his 'servant' and telling them to change into a maid outfit, mostly to tease his partner, Tsujimura.

Befitting a detective, Ayatsuji is highly intelligent and observant. When deducing, he remains blank-faced and unexpressive, using his wit and logic to outsmart his opponents, and he easily succeeds in finding the truth. He is called the “Homicide Detective” and carries a deathly and imperturbable air, and he is highly dangerous enough to be seen as a threat by the government and to be put on the list of Extremely Dangerous Ability Users. Due to his rather cocky air, he calls people simple-minded and doesn't hesitate to tell people they lack of brains when he explains a case. Additionally, he does not take higher-ups seriously and flaunts his more rebellious streak, ignoring orders from the Special Division, slipping through a sniper team whenever he wanted to, and even sabotaged the security cameras in his agency building in the past, causing them to stop installing cameras from then on.

Despite his aloof persona, Ayatsuji occasionally breaks his poker face. He show fragments of emotion and his harshness tends to alleviate slightly. Ayatsuji displays anger and fury typically towards his archnemesis Kyōgoku and his schemes. In addition, he does have a soft side he only shows very rarely.

Another, his ability, causes an accidental death to a person or a group who either killed or attempted to kill, so long as the investigation can prove the suspect acts with the intention to kill and the case is under the commission of Ayatsuji.

Once the ability activates, which Ayatsuji cannot control, the suspect will be found dead regardless of the location, with the causes of death varying. Even if the commission is cancelled half-way through, the activated ability cannot be terminated nor neutralized, and the convicted suspect will die in an accident.

Due to his ability's danger, plans to assassinate Ayatsuji get submitted to the higher-ups in the Special Division two to three times a week, but such plans continue to get rejected due to the usefulness of his ability.
