Kakushite! Makina San!!

Makina Agatsuma is actually an AI robot created to captivate men. She immediately sets her sights on seducing Eita Akutsu to make him her pawn. However, Eita is extremely uncomfortable with anything sexual. On top of that, Makina herself is restricted from accessing sexual content due to limitations in her programming...

Eita Akutsu begins living together with Makina Agatsuma to help her maintain a normal life without revealing her true identity. Carefully avoiding the watchful eyes of their landlady, the two head to a park where Eita’s close friend Mamimi is waiting. There, they’ve arranged to receive a hand-me-down school uniform for Makina.

Makina, whose mechanical identity must remain a secret, frantically calls Mamimi from her apartment to explain away the commotion caused at school. During the call, she starts making odd sounds due to Eitas ongoing maintenance, but somehow manages to keep her cover until the end. Just as things settle down, a mysterious girl suddenly appears at their apartment...

Shrunken down to a tiny size, Makina finds herself in a tense face-off with a now gigantic Mimika. However, she’s unable to make a move—Eita is being held hostage. Mimika threatens Eita, demanding that he perform maintenance on her. As Eita trembles in fear, Makina reveals a secret plan for a dramatic comeback.

Eita continues repairing Makina’s fragile left leg, but thanks to Mimika’s suggestion, they visit a riverside embankment that lingers in Makina’s fading memories. Meanwhile, Mamimi, still determined to take down Eita, encounters a new robotic warrior named Alma…

As Eita and Makina head to school the next day, Makina, thrilled by the improvements to her left leg, can’t stop smiling. But in gym class, disaster strikes—soft tennis is on the schedule! Eita just wants to keep a low profile, but Mamimi has other plans, setting a devious trap that will drag him right into the spotlight…
