Rinko Sakuma is still bound by contract to the lustful demon Azazel, and Akutabe's demon detective agency keeps taking cases that require summoning worse company. This second season picks up directly after the first, throwing Sakuma back into schemes with Beelzebub, Undine, and the rest of Akutabe's rotating cast of demons. The agency's jobs grow more chaotic and the crude gags and outrageous set pieces escalate from where the original run left them.
