A man spends a whole lifetime chasing magic he'll never touch, dies in failure, then wakes up 400 years later with everything he learned still burning in his head. The show doesn't waste time on pity or redemption arcs. Ephtal walks into a world that has forgotten him and starts breaking it open with knowledge everyone else thinks is ancient history. This is what happens when you give a protagonist the one thing isekai usually denies: the actual consequence of failure, followed by the means to do something about it. The magic system isn't window dressing; it's the entire point of his existence across two lifetimes.

Ephtal wakes up in a fantasy world with a second chance at life. A reincarnated man from modern Earth, he arrives burning with ambition to master magic, only to discover he has virtually no talent for it. He gives his whole life to the pursuit and dies in anguish, short of the peak he chased. Four hundred years later, he is reborn under the same name with his memories, knowledge and power intact. The world he returns to has changed: magic has fallen into steep decline, and spells from his era are now treated as miracles. In this weakened age, the mage who once had no talent finds himself without equal. He enters a prestigious magic academy to restore the true art of sorcery, and as his strength shakes the world, old legends begin to stir. Armed with experience and overwhelming magical prowess, he begins his second climb toward the peak of magic.
