Kanpeki Ojousama no Watakushi ga Dogeza de Mazo Ochisuru Choroin na Wakenai desu wa!

Every student at her school instinctively straightens their posture around Irina Shirogane, beautiful, composed, and completely untouchable. At least, that's the image she projects. Behind closed doors, she's hiding a secret that would shatter her entire reputation. When Yuuji Sado stumbles into the wrong classroom at the wrong moment, he accidentally becomes the one person who knows exactly what lies beneath her perfect exterior, and that discovery changes things between them in ways neither of them expected. The setup is essentially about the gap between who Irina appears to be and who she actually is, and how that tension plays out when someone finally sees through the facade. It's a 4-episode OVA from PoRO adapted from a light novel, so it moves quickly and stays focused on that core dynamic rather than sprawling into subplot territory. The psychological undercurrent gives it a bit more texture than you might expect from the premise alone. If you've watched something like Shoujo-tachi no Sadism The Animation and liked the idea of dominant-presenting characters hiding their true nature, this hits a similar note. Fans of Boku Dake no Hentai Kanojo The Animation who appreciated character-driven tension over pure shock value will also find it familiar territory. The contrast in Irina's character design, prim and authoritative publicly, completely different privately, is handled with enough consistency that it feels like an actual character rather than just a setup.
