Tsuundero is a hentai OVA series that follows the erotic misadventures of students at a depraved academy. Each episode features a different scenario, such as the school idol Yuka Yoshii—beautiful, athletic, and secretly perverted—who discovers her classmate’s obsession and eagerly turns fantasy into reality, or the strict student council president who finds herself blackmailed by disgruntled club members and drawn into unexpected pleasure.
