Akuma Umare is a nobody. He always dreams of going to another world and being the hero. But when he is Isekai'd, he's transported with the school pretty boy. Being discriminated all his life for his oddly colored hair and being treated like trash, he swears to defeat the demon before the hero. What he doesn't know is that the summoning ceremony has gone wrong. The people summon the hero but also summon the demon king. But Akuma, oblivious to this, sets out to surpass the hero in strength. But there is more to this world then meets the eye.
