Yukito has resolved over 50,000 cases, and his ability is said to have killed in the billions—making him both feared and sought after by authorities.

He maintains two pet cats and a basement full of handmade dolls he cherishes.

His personal style extends to coffee: he prefers it with two spoons of brown sugar, no milk.

He is the protagonist of the gaiden side story Bungo Stray Dogs Gaiden: Ayatsuji Yukito vs. Kyōgoku Natsuhiko, inspired by the real-life mystery novelist Yukito Ayatsuji who authored Another.

Hired for his uncanny deductive skill and ability, he often works under supervision from agent Mizuki Tsujimura, who is assigned to monitor him closely while he solves cases involving other espers

His supernatural ability is known as Another (Anazā). By uncovering the truth behind a murder and identifying the culprit, Yukito triggers an unavoidable “accidental” death for the criminal—regardless of location, protection, or distance—but only if the culprit is truly guilty. The death's cause is unknown and unpredictable. This ability makes him one of Japan's most dangerous esper users—assigned special A‑Grade status—and a subject of constant surveillance. Plans to eliminate him are reportedly proposed multiple times a week, but are always rejected due to the utility of his ability.

Yukito works as a detective at the Ayatsuji Detective Agency and is temporarily commissioned by the Special Division for Unusual Powers due to his unique ability, although he's closely monitored and restricted by them.

A highly observant and intellectual detective, Yukito presents a cold, emotionally detached, and reserved demeanor. He rarely shows vulnerability or warmth, though he has peculiar hobbies—such as collecting dolls in his basement and keeping two pet cats—with which he occasionally expresses affection . He is blunt, often calling others naive or foolish, and has zero tolerance for anti‑intellectualism. He enjoys reading, mahjong, and crafting doll figures. Yukito also has specific personal likes and dislikes: he dislikes natto and intellectual laziness, and prefers his coffee with two spoons of brown sugar and no milk .

Yukito is depicted with short wavy blond hair and golden eyes. He wears half-rim light sunglasses, a flat black cap, gray gloves, and carries a smoking pipe and a ball-jointed doll. His outfit consists of an ochre-yellow jacket with a red collar, a white shirt with vermillion checkered trim, a gray knit vest, dull orange checkered knickerbocker trousers, and beige boots. In some scenes he switches to a light-colored double-breasted long coat over a black turtleneck, paired with light trousers and boots .
