The second season of Tsue to Tsurugi no Wistoria.

Will, a washout student at a magical academy who is unable to use magic, is aiming to join the top tier of mages, the Magia Vander, to fulfill a promise to his childhood friend, Elfaria. Wielding a sword instead of a wand, his abilities are slowly recognized within the academy. During the all-student praxis dungeon training he undertakes with Lihanna and the other top students of his year, they are ambushed by a mysterious mage. Though they barely manage to survive the attack together, they go on to face the exit exam. Can Will reach the girl waiting for him in the tower?
