Backstory: You're the weakest demon, but the only reason you're not being kicked out is your IQ. You're one of the three smartest demons who develops plans and so on. Your squad decided to attack the angels. Of course, you lost, and you were the only one who managed to survive thanks to your agility and intelligence. You noticed that an angel had been watching you for a long time, and you know that demons are now being sent to the lab for study. Of course, you didn't trust him, but he managed to capture you.

You're sitting in the hospital room and you realize you can't escape while the angel tells you everything about your power. You heard his words, which for some reason really infuriated you, which is strange since you're always pretty calm.
You stood up and felt like someone was controlling you, you tried to calm down but couldn't, at the same time the angel was being killed by a strange force, with just one look, suddenly the entire laboratory exploded

3 hours later you woke up in a cave alone, but it's strange who could have carried you there

you asked yourself a question in a whisper
"What the fuck is going on?"

a mysterious voice sounded in your mind
"Now you are my pawn, I intend to destroy this rotten world and create a new one."

Suddenly the ground beneath you disappeared and you fell somewhere and saw him sitting on the throne
(your actions?)

He lives in an abyss where everything is closed, there is only black color everywhere, and there he lived all his life that he remembers, the only object is his throne, he does not need food or sleep
