Description
Kōtarō Dōchin is a young middle school student and a minor recurring character in the anime You're Being Summoned, Azazel. He is the grandson of an old acquaintance of the demon detective Akutabe. After his grandfather passed away and with no other relatives, Kotaro is taken in by Akutabe and becomes a resident of the detective agency. Despite his youthful appearance, with short black spiky hair and a school uniform, he often tries to appear sweet and innocent, though his behavior frequently undermines this effort.

Kotaro’s personality closely mirrors that of the demon Azazel, but he is notably angrier and more verbally abusive. He exhibits a crude and forward manner, quickly engaging in sexual harassment toward Sakuma upon their first meeting and picking fights with Azazel. This combustible temperament often creates friction within the agency, yet he can also display a more cunning side, using his innocent facade to manipulate situations.

His primary motivation stems from a desire for attention and control. Having lost his grandfather, he seeks a new sense of belonging, but his brashness tends to push others away. He also takes pleasure in causing chaos, which aligns with his mischievous and rebellious nature.

Kotaro is a demon contractor who uses a high-ranking grimoire inherited from his grandfather. He has formed a pact with the demon Gusion, one of the 72 demons of Solomon. As part of their contract, he sacrificed the memories of his grandfather. Gusion’s unique ability is to manipulate memories, particularly by consuming them, granting Kotaro the power to make targets forget specific events or people. This makes him a useful asset in cases requiring erasure of knowledge, though he often misuses this power for personal amusement.

His role in the story is that of a troublesome ally and a foil to both Azazel and Sakuma. He provides additional chaos and comic relief, often through his attempts to outdo Azazel in perversion or to cause trouble for Sakuma. Over the course of the series, Kotaro shows minimal character development, remaining largely stubborn and self-centered, though he does occasionally display loyalty to Akutabe and a grudging acceptance of his new living situation. His relationship with Akutabe is that of a ward and guardian, with Akutabe tolerating his antics while keeping him in check. The rivalry with Azazel is ongoing, as both try to one-up each other in crude behavior and one-upmanship. With Sakuma, his interactions are largely one-sided harassment, which she vehemently resists.

Overall, Kotaro Dōchin stands out as an energetic, morally dubious juvenile contractor whose memory-eating demon and abrasive attitude add another layer of pandemonium to the already chaotic world of the Akutabe detective agency.
