Арідзука Такао

A high-ranking officer from the Tokyo Metropolitan Police Department with the rank of Superintendent, he is feared by low-ranking officers since his mere presence in a police station during inspection would mean the end of someone's career as he always bring a notebook with him. However in reality, he is lenient and willing to make arrangements (even if he has to make personal sacrifices to make such an arrangement possible as is) to accommodate the need of his subordinates so long as they get the job done in the end.
