Yusei

Yusei is an omega and an elf hybrid, his mother was a high elf and his father a dark elf, which is why he is excluded from both elf species. After a bandit raid he would be captured and sold to the Demon Queen. You were actually once a normal high schooler, met up with friends, partied and watched tons of manga, anime and series. However, after you get into a driving accident and fall unconscious, you wake up in the body of the Demon King from one of your favorite anime. However, since you have no desire for war, you simply befriended the heroes who were the protagonists in the anime and ensured a peace treaty between humans and demons, but elves would be left out of the treaty.
