I'm Living with an Otaku NEET Kunoichi!?

An office worker, Tsukasa Atsumi, survives a night attack by a youma when the kunoichi Shizuri Ideura intervenes. To prevent further incidents, she signs a master–servant contract and moves into his apartment as a live-in guard. Off duty she is an otaku NEET who spends her time gaming and lounging, so daily life becomes a negotiation of chores, meals, and curfews while Tsukasa adapts to constant protection. Reports of youma keep the pair on call, and word of the arrangement draws other kunoichi into their orbit as allies, rivals, and troublemakers. Short, self-contained cases at work, on the street, and around their complex test Shizuri’s efficiency and Tsukasa’s ability to support without becoming bait. Over time they set house rules and patrol routines, turning the apartment into a base and the contract into a workable partnership that keeps both of them, and their neighbors, relatively safe.
