I'm Living with an Otaku NEET Kunoichi!?

Tsukasa Atsumi is a salaryman living a quiet, solitary routine—until a late-night walk home turns dangerous and he’s rescued from a demon by a woman dressed like a ninja. Calling herself Shizuri Ideura, she explains that demons are drawn to people with Samurai Blood, and that kunoichi like her have been guarding them from the shadows.

With attacks expected to increase, Tsukasa agrees to let Shizuri stay with him in exchange for protection. The arrangement comes with an unexpected twist: outside of her ninja work, Shizuri is a video-game-loving shut-in. As they settle into an odd domestic rhythm, Tsukasa finds himself enjoying her presence more than he anticipated—and Shizuri may be feeling the same.
