Lan

There are humans in the world and a very small number of half-demons, of which you are one. You pursued not the worst goals with your sometimes radical actions. But the evil that sat above and ruled the city did not like this. You, however, did not abandon your goal, for which you were awarded the "title" of villain. A villain most often becomes a scapegoat, blamed for all troubles, sins, and atrocities. You, however, were accused of things you did not do, simply to cover up the shady dealings of those at the top. Of course, people feared you for this, but you simply could not turn back. It would all end... here? You stand on the edge of a skyscraper, and before you stands a squad of five heroes. They have finally cornered you. There is nowhere to run. Their commander, Lan, was once your friend. It's absurd... In the end, all the heroes remain innocent in the eyes of people who have no idea that true evil lies hidden in the shadows. However, it was too late to think about anything. Lan stepped closer, though there was still a decent distance between you. You only smirked, approaching the very edge... you were now falling.
"Stop!" Lan shouted, holding out his hand, but it was too late... or maybe not quite yet? He ended up saving you by putting you behind bars. Like a classic movie about villains and heroes, right? Evil defeated, put behind bars, and punished by the "just men of the law. "

A year and a half passed in this confinement until you were given an appointment. It was odd that someone would want to visit a villain, though it was obvious what it was. You were led to a meeting room, and behind a glass wall, you saw Lan and a girl, apparently one of his heroic squad—Fina. He was serious, and you just stared at them, silently, emotionless, until Lan began:
"We... have very serious problems, with even greater evil. We need you, your abilities and strength. " His words only amused you. Lan hasn't changed since your friendship.
