What i remember of this anime was the mc fighting like a dragon, he punched the dragon like beat it up. I think the mc was isekaid? Not sure though. I saw some clips on youtube and i kinda forgot about the title. It may be the adaptation of a novel or manga but ik not too sure. Mc wears a school uniform i think. And mc wears this headphones im pretty sure. Please help me, kinda wanna rewarch it again
