Fubi Kase

At just 28 years old, Fubi Kase has already carved out a formidable reputation within the Metropolitan Police Department as a sharp and seasoned detective. She frequently crosses paths with her long-time collaborator Kimihiko Kimizuka at crime scenes, their partnership built on years of mutual reliance. On the surface, she projects an air of cool detachment laced with biting sarcasm, while privately waging a losing battle against her smoking habit—her ever-present cigar has become something of a personal trademark. Beneath this exterior, however, lies a far more consequential truth: Kase is the 'Assassin' of the Twelve Tuners, a covert group sworn to uphold the world's balance. Guided by an unwavering and ruthlessly pragmatic worldview, she does not hesitate to take extreme measures when the stakes demand it.
