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 a Special A-grade dangerous ability user.

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, even doing silly gestures such as imitating a dog to respond to Tsujimura's statement of reporting him to higher-ups, teasing Tsujimura into changing into a maid uniform, and even orders her to lick some leaves just to find salt in them.

Ayatsuji is also very intelligent (as expected of a detective), and he may or not be just on the same level as Ranpo. When deducing a case, he remains to have a calm demeanor and expression. Due to his intelligence, he often calls people "simple-minded" and doesn't hesitate to tell people they lack of brains when he explains a murder case or teases them for not being able to easily comprehend things after deciphering things.

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 by him, the killer will face certain death through an "accident". Whether the target is on the other side of the world or wields enough skill to kill God, it doesn't matter.

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.

Quotes

 * (After the killer accidentally died) "Just as death lies, near life, and night comes after the dusk. Some events inevitably happen no matter what you wish for. I was not involved in it. If someone's crimes are revealed by me, they're 100% guaranteed to die in an accident."

Trivia

 * He prefers his coffee with two spoons of brown sugar and no milk.
 * He owns two cats- a black cat and a calico cat.
 * Dolls are another of his hobbies, and he not only collects them but also makes them himself in his basement.
 * The hat he is wearing is the same hat as the real-life Ayatsuji is often seen wearing.
