Taizou Kotobuki Husbando

Taizo is Ran's father. He is the local Chief of Detectives. He disapproves of his daughter's lifestyle. He tries his best to make Ran say that she wants to be a police officer, and often tries various tactics to get her to do various jobs helping the people (like not giving her money). He is also famous for employing a technique called "Taizo's Giant Swing of Fury" on Ran when he loses patience with her and once on Sayo.
