I'm Living with an Otaku NEET Kunoichi!?

To protect an ordinary businessman, Tsukasa Atsumi, from demons, a brilliant but reclusive kunoichi, Shizuri Ideura, forms a master-servant pact with him, agreeing to stay by his side. Despite her cool, demon-slaying exterior, Shizuri is actually a lazy otaku who spends her days glued to video games. As Tsukasa indulges her whims and they settle into an easygoing life together, a quirky group of kunoichi begins to gather around them.
