Hatanaka, an obsessive fan who supported Hibiki during her underground-idol days, reappears before the now-popular round girl. Enraged by her affair scandal with a famous fighter, he uses a brainwashing mixer to implant suggestions in Natsume. Forced to wet herself in public, Hibiki begins losing her reason. When she rejects the embarrassing past he remembers, he completely shatters her identity and overwrites it, reducing her to an obedient servant who can live only within the attention and approval he grants her—a disturbing revenge NTR fantasy.
