Description
Kyōsuke Kishi is an oni, a type of yōkai, who resides in the town of Sakurashinmachi. He serves as the personal secretary and assistant to Hime Yarizakura, the town's mayor, and is also a member of the Hiizumi Living Counseling Office. At eighteen years old, he stands 177 centimeters tall and was born on February 10. He has black hair, gray eyes, and typically wears glasses. A bracelet-like seal on his left wrist suppresses his supernatural oni strength; when he unleashes his true power, two small horns emerge from his head. He is the older brother of Touka Kishi and has known Akina Hiizumi since childhood.

Kyōsuke's personality blends strong professionalism with deep familial loyalty. He is sincere, formal, and adheres to a strict code of duty, taking his responsibilities as the mayor's assistant very seriously. He can appear harsh toward Akina at times, partly because he believes Akina's abilities as the oyakume have not been sufficient to protect the town, and he feels that the yōkai in the human world have suffered as a result. This critical attitude often leads to arguments with Akina, who teases him for having an intense sister complex. Despite these clashes, Kyōsuke and Akina share a close, long-standing friendship and are often seen bickering like old comrades. Kyōsuke is also extremely protective of his younger sister Touka, a trait that other characters often remark upon. He enjoys reading, and his favorite food is beef bowls.

His primary motivation is the protection of Sakurashinmachi and the peaceful coexistence of humans and yōkai within it. He takes his job seriously and works diligently to help Hime manage the town's affairs, believing that order and security must be maintained. His deep concern for Touka also drives many of his actions, as he wants to keep her safe from harm. Over the course of the story, Kyōsuke undergoes gradual development. His initial skepticism toward Akina's role softens as he witnesses Akina's growth and dedication, and he learns to temper his overprotectiveness of Touka, allowing her more independence. He remains a steadfast ally and a capable enforcer in the town's defense.

As an oni, Kyōsuke possesses superhuman physical strength, which he normally keeps contained with his wrist seal. When the seal is removed or he fully releases his power, his horns appear and his strength becomes even more formidable, making him a powerful combatant in direct physical confrontations. He often uses this strength to support the main team during battles against threats to the town. His role is that of a reliable protector and a stern but loyal friend, bridging the gap between the human and yōkai communities through his service and his relationships.
