Arifureta: Unrestrained Strongest Teacher (Dropped To The Bin)

Mikami Satoru, a teacher from Nagumo Hajime's school, is coincidentally summoned to another world with his entire class (and another teacher)! What will he do when he realized that he was summoned? Anything? Have some fun? Although, something's different from him since he had been summoned. How does he even act so normally, when there is no way home other than winning some sort of war? This, is his life in (yet again,) another world. (Note: MC is already OP from the start. Like, seriously OP. Also, he's a... little perverted.) (Probably a more original take on the Arifureta Fanfiction.)
