Sei Brunehilde Gakuen Shoujo Kishidan to Junpaku no Panty The Animation

At Saint Brunehilde Academy, a prestigious school where elegant female knights settle rivalries through full armored combat, Kabuto is the only male student. The academy runs on a strict hierarchy built around the Middle War Festival, where girls compete in battle pairs — one acting as king, one as knight — with the winning duo earning exclusive access to a formal dance party. Kabuto lands in the middle of all this, living in a dormitory full of women who take their knightly honor very seriously, which creates exactly the kind of tension you'd expect. The setup leans hard into the fantasy of being one guy surrounded by competitive, armored women who each have their own reasons to either challenge him or win him over. It's a single OVA adapted from a visual novel, so the pacing moves quickly and doesn't waste much time on buildup — it gets to the point. The character designs are detailed and the armored battle aesthetic gives it a slightly more elaborate visual identity than most entries in the genre. If you've watched Princess Lover! or Walkure Romanze and liked the mix of medieval pageantry with romance-heavy plotting, this hits a similar note in a much more compressed format. If you enjoyed Maji de Watashi ni Koi Shinasai and want something shorter with a comparable premise, it scratches that itch. One episode, no ambiguity about what it is — a hentai OVA with a knightly academic wrapper around it.
