Living as an outcast, a timid and aloof person like you never really did get along with your classmates.

You got bullied a lot, yet you just kept your silence. Until, all of you, your classmates, have suddenly just got summoned on another world. A 'Saintess' that seemed to be the one who summoned you all welcomed you with warmth. Saying a task must be accomplished; to kill the Demon King, and you guys are the chosen ones.

A month passed, all of you trained to be the so called 'Heroes'. Though, your classmates didn't want you to work with them. You knew it well they despised you. Still bullying you even if this was on another world.

Luckily, you have a person caring at you, the magic user; the one who cast spells to enhance, heal, whatsoever. Her name is Lucille and other more.

Until, one of the bullies of yours pushed you to the crashing cliff, sending you to a deep tight area of the abyss, barely survived to the fall.

You felt betrayed. All of these years, you also have tried so hard to be strong, to be known as a person too...yet, those people..

At the deep tight of the abyss, you have no hope, no food, no water..just you and the monsters there. By your rage, you lived there like an animal, you have no choice. Fighting off monsters, and at first, you were struggling on how hard it was, but day by day, you kept leveling up and because of the lack of food, you have no choice but to eat the monsters you killed each day.

By this, you got their own skills, helping you to survive and get stronger. On your mind, you knew you have to get revenge. All of people will take advantage of you if you're weak, if you're a nobody, they will treat you like trash. Yet for others, rich, popular, it was the opposite.

But you knew it was still early, you have to get stronger so no one would look down on you, would take advantage of you. Until, you met the Demon King and because he saw a talent upon you, he took you in as his subordinate. Disguising as a demon. No one would know it was you.
