I have no Talent and I must Fight

MC took a gap year, and went to a school, unbeknownst to him, is a Combat MagicBattle Academy! High school teenagers challenge each other with duels, girls with great acrobatics flying around waving their swords, and really really strong people are everywhere. What type of school had he been enrolled at? Everyone's crazy!

Loosely inspired by Gakusen Toshi Asterisk (Asterisk War)

Alt title: Stumbled in an Academy with no Abilities
