Ikki Nagumo; an average teen with slightly above average performance in athletics. He was decently good-looking but nothing to really brag about. He had friends, albeit unique ones, and a loving older sister who payed for their house's bills while she was overseas.
But such an average life, filled with mediocrity, was soon to come to an end when a black maw-like hole appeared in his room and sucked him in.
The only way to get out of the hell it put him in? Kill the boss for the floor. What's the boss? A gigantic Minotaur.
(A/N - I mean, anyone who knows anything will get who I've combined to make this OC. Nagumo comes from Hajime Nagumo from Arifureta. Ikki comes from Ikki Kurogane from Rakudai Kishi. I'm not giving the MC Guns either. Who would want to use guns in a world of magic and supernatural abilities? That'd just be plain and boring as hell.)
