Majuu Jouka Shoujo Utea

When two high school girls stumble into a secret war against supernatural creatures, things head in a complicated direction fast. Karen discovers that her classmate Mitsuki has been living a double life as a magical girl named Grace, fighting off Lust Demons that prey on their city. Rather than run from it, Karen gets pulled in herself, transforming into Charm alongside her. The setup has that familiar magical girl skeleton — mysterious fairy, transformation sequences, powers tied to personality — but this is a 4-episode OVA from T-Rex adapted from Suzu Suzuhane's manga, and it leans hard into adult territory from the start. Don't expect Madoka Magica's psychological depth or a clean action story. The tone is suspenseful in places, the character dynamic between Karen and Mitsuki has some genuine intrigue, and Mitsuki's sudden disappearance partway through gives it a thread worth following. If you've watched something like Kuroinu and want a shorter series with a magical girl framing built around it, this scratches that itch. The transformation system — Charm and Grace forms with distinct abilities — adds some structure to the fantasy, and the soundtrack actually does some work keeping the atmosphere consistent. It's a niche watch, clearly aimed at fans of the hentai genre who also want a recognizable plot wrapper around everything. Manage expectations accordingly, and it delivers what it promises across its four episodes.
