Mannenhira Kyoushi no Shien Majutsushi, Saikyou no Kenja ni Naru: Funinki no Shien Majutsushi wa Kyuuryoudorobou dato Majutsu Daigaku wo Kubi ni Natta ga, Shuss

Thor, a former hero’s party member, teaches unpopular support magic at a magic university—until saving a student gets him fired. With nowhere else to go, he follows that very student, Reina, to the empire next door, where a princess hires him as a court magician.Though he underestimates himself, Thor’s support magic is actually extraordinary, and his former students are already achieving greatness worldwide. Determined to at least look cool in front of them, the “useless” teacher begins his new life, unwittingly as the strongest sage.
