Synopsis

In "I'm Living with an Otaku NEET Kunoichi!?", Tsukasa Atsumi enjoys a quiet, solitary life as a salaryman until one night he is suddenly saved from a demon attack by Shizuri Ideura, a ninja who appears after rescuing him. Shizuri explains that Tsukasa is a target because of his Samurai Blood, a trait her clan has protected for generations. Expecting more frequent attacks, Tsukasa agrees to let Shizuri stay at his home to guard him. However, he soon discovers that Shizuri is more interested in playing video games than carrying out her ninja duties, as she is actually a NEET otaku.
