Vermeil in Gold Kinsou no Vermeil: Gakeppuchi Majutsushi wa Saikyou no Yakusai to Mahou Sekai wo Tsuki Susumu English Dubbed

Meet Alto, a hapless student at Royal Ortigia Magic Academy whose academic performance leaves much to be desired. Rather than take a more sensible approach to salvaging his grades in time for graduation, Alto decides to summon a bit of otherworldly assistance. Only after does he learn he’s bound the legendary she-devil Vermeil into service as his familiar! But while Vermeil is a powerful ally sure to turn his grades around, her magic can only be replenished with a kiss, and that makes everything go to hell with Alto’s jealous childhood friend, Lilia.
