Eita Akutsu is an introverted, lonely, and hopelessly inexperienced mecha otaku. But even he has a crush—on the popular gyaru, Makina Wagatsuma.

However, Makina’s true identity is no ordinary high school girl—she’s an AI-powered robot designed to seduce men.

Armed with nothing but half-baked (and wildly inaccurate) knowledge about seduction, Makina tries to manipulate Eita.

Now stuck in an unexpected cohabitation arrangement, Eita helps Makina blend into human society while keeping her true nature a secret.

Back at school, Makina slips on a banana peel and nearly falls apart—literally. Eita is always on edge, terrified that her left leg will break off.

Determined to clear things up, Makina secretly calls Mamimi from the apartment. But Makina ends up making some very suspicious noises over the phone.
