Episode 3: Kegareboshi

Ibuki and Kokoharu (also referred to as Iori and Kokoha in some translations) are the rookie idol duo Stellarista (or StellaResta), dreaming of stardom. After Ibuki learns the shocking truth about Kokoharu’s scandal with their manager Matsunami, she storms into the weekly magazine’s office in a rage. There, she’s offered a drink that turns out to be laced with drugs.
Trapped by producer Kurotsuka (or Kurozuka), who orchestrated the setup, Ibuki is pulled into a vortex of overwhelming pleasure. Meanwhile, the story shifts focus to the corrupted idols: Kokoharu, now dressed in bondage gear, confronts the bound Matsunami while expressing twisted feelings for him. Ibuki, whose heart has been stolen away, and the mocking Arisa join in, leading the three fallen idols into a state of ecstatic bliss.
