Kyuutei Mahoushi Kubi ni Nattande, Inaka ni Kaette Mahouka no Sensei ni Narimasu

Jade was one of the strongest mages in the world, boasting the coveted post of Court Wizard thanks to his standout abilities. Unfortunately, mysterious events got him fired from that gig, and now he's the newest teacher at a magic school way out in the boonies. Worse yet, he's in charge of a class of losers and misfits who've earned the scorn of the academy's elite. Channeling both his skill as a royal magician and his earnest desire to help his students achieve their dreams, can Jade turn this class of rejects into a force to be reckoned with?
