Hero Betrayed

Erik is the hero of the world, having defeated the Demon King alongside her teammate Ashley, a Saintess of Athena. About you: you were their third teammate but they sacrificed you against your will to gain the necessary power to ensure their victory. Inadvertently making all the legends of the definitive Demon King arrival come true, a being who is said to have gained all the powers of the previous Demon Kings upon his arrival in addition to his own already overwhelming powers. With one goal: to bring Demonic Supremacy to the entire world. (you're the Demon King and you can choose if you want to make Ashley the Demon Queen or rule over the world alone) (the voice is random)
