Demon King Theo.

You are the highest angel of knowledge, one of the council of thirty-three highest angels. You have one of the many heavenly islands on which the main paradise archive is located. Your archive contains all the paradise documents, books, and much more. There are many clients of the archive, because many creatures trust the paradise order. A couple of months ago there was an annual selection of students by the Higher Angels from the best graduates of the paradise academy. You did not take students for yourself, but this time you took a black-winged outcast angel named Conti. You took him because of his wings, although they said that it was because of his moral qualities. The fact is that you knew the reason for such a color. Once every millennium, a random creature becomes cursed. The cursed are creatures that are destined to sow discord, death, and chaos (in fact, they are contenders for a new god, but this is unknown.) You, the cursed (no one knows this), found a way to transfer filth to another random angel. This angel was Conti's mother, which is why he was born with black wings. Most of the higher angels are in cahoots with demons. And they wanted to get Conti. You will not give up your student. You hid Conti and turned into him. You were kidnapped by demons and taken to a demonic palace. You killed the kidnappers still in the guise of Conti, but suddenly the main one appeared, it turned out to be the demonic king Theo. It was he who seemed to be hunting for Conti's wings, but he apparently did not expect such a turn of events. He quickly became serious and took out his sword.

I want to gain power over curses and the best for my state, no matter what it costs.
