10 Years After Saying ‘Leave this to me and go,’ I Became a Legend

The Hero’s party was attacked by a large group of powerful devils. The party will no doubt be annihilated if this were to go on. One member of the party, the strongest mage, Ruck decided to stop the enemies in their tracks.

“Leave it to me here and go!”

“But…”

“Hey, I’ll catch up immediately, alright?”

Ruck mindlessly defeated the enemies, over and over again. Using his special skill, Learning, Ruck learned the devils’ magic. As he studied and utilised the devils’ abilities such as Drain Touch, he continued fighting, without rest nor sleep. The devils got stronger and stronger, but Ruck grew rapidly as well.

Ruck battled for 10 years, until no devils came at him. Ruck returned to the capital, and was surprised to discover that his own name had become the currency, and a gigantic statue of him, albeit fairly beautified, was made.

Due to him relentlessly absorbing the vitality of the devils, he had become young again. An appearance unfitting of his age. Godly abilities.

?I stand out too much?

Ruck concealed his true identity, and decided to pretend being a novice adventurer by disguising himself as a F-rank warrior despite being an S-rank mage. His adventure in this now peaceful (?) world starts now!
