Cosplay Change: Pure-kei Joshidaisei no Kiken na Seiheki – Episode 1 (EN)

Aima Imoko, a stunning 165cm tall college girl with an impressive 89-52-86 figure, is a pure-hearted ojou-sama and hardcore fujoshi who falls for anime characters, scaring off real suitors with her quirks and mysterious ability. Her power activates through "Cosplay Change": wearing a costume summons her into an anime world synced with reality, often twisting it into something wildly sexual.

One day, while browsing a shady shop, she discovers a revealing giant-breasted youkai detective outfit from her favorite anime. Overexcited, she tries it on inside the store, triggering the change. Suddenly, she transforms into the seductive "Hyakkiya Tantei Hikari" (complete with her iconic line echoing: "Any case solved in a flash~! Hyakkiya Detective Hikari here!! Nyan!"). The perverted crossdressing store manager gets pulled in too, becoming her chaotic partner in this fantasy realm.

As the "investigation" unfolds, her overflowing curves strain against the skimpy costume, driving the manager wild. He launches relentless lewd assaults amid the bizarre, erotically altered mystery—leading to intense, white-fluid-soaked encounters. Will they solve the case, or succumb fully to the dangerous fetish-fueled fantasy? This premiere episode sets the tone for Aima's dual life: innocent pure girl vs. hyper-sexual cosplayer.
