Koko wa Ore ni Makasete Saki ni Ike to Itte kara 10-nen ga Tattara Densetsu ni Natteita.

A party of heroes is overwhelmed by a powerful group of devils. Rakku, the party's strongest mage, tells the others to leave while he holds the enemies off. He defeats them repeatedly, using a skill that allows him to learn their magic. Over the course of ten years, he fights without rest, growing stronger as the devils do. When he finally returns to the capital, he finds that his name has become legendary and a statue has been erected in his honor. His appearance has changed due to absorbing the devils' vitality, making him look younger than his age. To avoid attention, Rakku hides his identity and pretends to be a low-ranked adventurer, beginning a new journey in a seemingly peaceful world.
