Yatsuki Nishizuru works a dead-end job at an Akihabara junk-parts shop and counts himself ordinary apart from one thing: he sees yokai, and mostly copes by ignoring them. That ends when Rokka, a rokurokubi who looks like a teenage girl, moves into his apartment and leaves him the sole protector of a growing household of yokai women. Kazuki Funatsu's ecchi action-comedy runs Yatsuki's routine off the rails through one spirit encounter after another.
