Mahou Shoujo Yuusha-chan

Meet Arihara Yuna. She’s a prim and proper athletic honor student by day and Magical Holy Angel Cat Princess Yuusha, the magical defender of good girls and the bane of Badguy by night!
Except she’s actually a total masochistic slut with ginormous boobs who always loses to Badguy and turns into his plaything. Her real magical girl name is Magical Horny Angel Cat Princess Yuusha.
This is her story.
