Kou finally locates the older brother who disappeared from home, only to discover that Takumi now runs the Mikuni Detective Agency and has no intention of returning. With his original plan defeated, Kou stays and joins the business himself.

The agency's eccentric staff and equally troublesome clients ensure that little work proceeds normally. Simple assignments slide into absurd situations, leaving Kou to cope with a brother whose new life is stranger than the disappearance he came to solve.
