Hisui Hoshikawa

Hisui Hoshikawa is a young man of Japanese-European descent serving as a member of the Exploration Division within the clandestine organization known as 'Bubo.' His most striking features are his heterochromatic eyes and his innate ability to conjure and control fire. Though he carries himself with impeccable manners and unwavering dedication to duty, deep-seated childhood trauma has left him instinctively guarded around women and quietly insecure about his own appearance. Alongside his mission to safeguard rare and extraordinary artifacts, he pursues a deeply personal quest to locate a book connected to his late mother. Through the bonds he forges with his companions, he slowly begins to heal the wounds of his past.
