Yukichi Fukuzawa

Height: 186 cm (6'1")

The president of the Armed Detective Agency, who manages the hooligans. Although he doesn't often come out, at a critical moment, he triumphantly takes command. Because Yukichi is a man of dignity and status, it seems even the frivolous Ranpo will actually work if he orders it.
