Demon Lejes Rimul, from the video game The Seventh Saga

"The game takes place on a world called Ticondera. Five thousand years before the beginning of the story, a divine being named Saro defeated an evil entity named Gorsia with the power of seven runes. In the years since then, the runes have been scattered across the globe.

Lemele, the son of Saro, was born 100 years before the beginning of the game, and became a hero when he defeated the demon Gariso. Now 100 years old, Lemele has become the benevolent and powerful ruler of the world." Courtesy of Wikipedia

Lejes Rimul is one of the seven apprentices, my favorite character in the game. As a demon, he seeks the power of the runes for himself, but across the course of his journey, he chooses self sacrifice and is ultimately reborn.
