Description
Taizo Kotobuki is the father of the series protagonist, Ran Kotobuki, and serves as the local Chief of Detectives. He comes from a family deeply rooted in law enforcement, as his wife Kiyoka, eldest son Yamato, and youngest daughter Sayo are also involved in police work. This background shapes his strict and traditional worldview, leading him to openly disapprove of Ran’s chosen lifestyle as a fashionable and independent kogal in Shibuya.

Taizo is characterized by his persistent and determined efforts to steer his daughter away from what he sees as a frivolous path. His primary motivation is to have Ran follow the family tradition and become a police officer, a goal he pursues through various tactics. These strategies often involve cutting off her allowance or assigning her tasks that involve helping others, hoping to instill a sense of duty and responsibility in her. Despite his stern exterior and clashes with Ran over her career choices, his actions are driven by a father's concern for her future.

In the story, Taizo serves as a primary source of comedic conflict with Ran, embodying the generational and ideological gap between the old-fashioned discipline of law enforcement and the free-spirited youth culture of Shibuya. His role as the police chief also grounds the series in the local community, often contrasting with the trouble Ran and her friends get into. His key relationships are with his family members. He is the patriarch of the Kotobuki household, which is portrayed as a family of cops, and his dynamic with his daughter is central to the series' ongoing subplot about her future. He also has a wife, Kiyoka, who shares his profession, and other children, Yamato and Sayo, who have embraced the family calling without the same level of rebellion.

Taizo exhibits moments of development in his relationship with Ran, as their frequent clashes are balanced by an underlying mutual care. Although he rarely admits defeat in his quest to reform her, he is shown to be a capable and dedicated officer who values justice. His notable abilities include his authority as the chief of detectives and a particular physical technique he is famous for using when he loses patience with his daughter, known as the Great Swing of Taizo's Fury. This over-the-top disciplinary action underscores his frustrated but ultimately loving relationship with his headstrong daughter.
