Yukito Ayatsuji

Yukito Ayatsuji (綾辻 行人,) is a detective and one of the main characters in the spin-off novel. He is currently one of the top-ranked person on the Japanese government's list of dangerous ability users.

Appearance
Ayatsuji has a short wavy blonde hair and gold eyes. He wears a half-rimmed, light-colored sunglasses, and a black hat. He also wears a jacket with a yellow ochre base with a red collar, a white shirt with a vermillion-based checkered border and a gray knit vest, dull orange checkered knickerbocker pants, and beige boots.

In his hand, he carries a smoking pipe and a doll.

Personality
Ayatsuji appears as a cold and emotionless man, though is considered to be fairly odd, as he has a basement full of dolls. He also seems to have a kind side to those he forgives, such as keeping a cat and loving it. He's not very talkative, and often plays with Tsujimura and makes fun of her.

Ayatsuji is also very intelligent (as expected of a detective), and he may or not be just on the same level as Ranpo.

But Ayatsuji is a very dangerous man, dangerous enough to be seen as a threat by the government and to be put on the list of Extremely Dangerous Ability Users.

Ability
Another allows Ayatsuji to see through the criminal in a murder case. Once the criminal behind a murder is identified, the killer will face certain death through an "accident".

Background
He is on the list of Extremely Dangerous Ability Users, and is thus being closely monitored by the Special Division for Unusual Powers; agent Mizuki Tsujimura is assigned to watch him.

A plan called 'Exterminate Extremely Dangerous Ability User, Ayatsuji Yukito’ gets submitted to the higher-ups in the Special Division 2-3 times a week but continues to get rejected due to the usefulness of his ability.
