Ashura Kokuhou is a third-year student at Mikuriya High School with shoulder-length strawberry blonde hair secured in a low ponytail and amber eyes. He typically wears a white button-up dress shirt layered over a burnt orange shirt, black pants, and shoes. Ashura exhibits a hot-headed temperament, particularly when encountering pretentious behavior, as demonstrated by his immediate irritation toward Hina Satō during their first meeting. He shares a close four-year friendship with Youta Narukami, dating back to junior high, and both now focus on university entrance exams. Their study breaks often involve basketball games, reflecting a shared history in the sport. During junior high, Ashura played shooting guard alongside Youta until a car accident caused a severe leg injury. Medical assessments confirmed he could never compete at a competitive basketball level again, ending his professional prospects. Within the series, Ashura primarily appears during Youta's interactions. His skepticism about Hina's claim of divinity prompts him to leave their initial encounter early, abandoning Youta with her.
