Rogas Meif

Race: 1/4 Elf, 3/4 Human

Rogas is one of the Septicolor Knights and fought the demon king along with the hero Tanzent. Him and Tanzent were friends both in love with Cadrea and seeing the two getting closer, Rogas became jealous. Tasked by Medelka the Mad, king at the time who didn't believe in the odds of winning, he blew the hero up in order to defeat the demon king.

It is later revealed that Rogas is a quarter elf. He did not inherit the long lifespan of elves and is artificially expending his lifespan to take care of his ill mother until her death. He see this as his punishment for betraying and killing Tanzent.
