Rakudai Kenja no Gakuin Musou: Nidome no Tensei, S-Rank Cheat Majutsushi Boukenroku

After coming from modern Earth, Ephtal devoted his entire first life in a magical world to mastering sorcery, only to die believing he possessed no real talent. Four hundred years later, he reincarnates a second time under the same name, retaining his knowledge and experience and determined to reach the summit that once escaped him.

The world he returns to has changed in a way he never expected. Magic itself has declined, and techniques once considered ordinary have become legendary skills most mages no longer understand. Ephtal enters this era as someone who would once have been called weak, only to discover that everything he accumulated in his previous life now makes him a power the academy can barely measure.
