落第賢者の学院無双 ～二度転生した最強賢者、400年後の世界を魔剣で無双～

Ephtal was already a reincarnated man in his first life, and he spent all of it chasing magical mastery before dying in despair at the discovery that he had no real talent for it. Four centuries later he is reincarnated a second time with his memories intact, enrolling at a magic academy in an era when magic has decayed far below what he knew. Knowledge that once marked him a failure now makes him untouchable. This light novel is the original source for its manga adaptation.
