I thought this was going to be my happily ever after. Isekai, fantasy academy, magic, beauties everywhere. Sure, gender roles are reversed and men are the weak sex here - so what? I'm a Transmigrator! Any minute now, they'll hand me some imbalance class, and I'll show everyone what I'm made of. Yeah, my body fits the local standards for men - no muscles to speak of - but that'll be more than made up for by the POWER And make up for it they did! S+ rank - sounds great, right? But the class... Catalyst "You'll make an excellent support and healer, the perfect backup!" ...huh? Okay. it's not THAT bad. Then I'll just live a quiet life and work as a medic But then... A cute student tried to devour me. Her head split open vertically, and she was about to bite my head off. And this is just my first day at Dienhell Academy Why has my isekai turned into a horror?!
