A young man who has been abandoned many times is the twelve angel wings of Satan Lucifer, who was once the leader of the 12 angels in heaven, and the strongest fallen angel. One night, the young man who was abandoned by his girlfriend was struck by a lightning bolt and came to the chaotic space where Lucifer was in. He got Lucifer's body, Lucifer's power, Lucifer's memory, he is the new Satan Lucifer. The family abandoned me? I don't hold a grudge, at most your family will perish. My lover abandoned me? I won't hate you, I will only make you regret it, I regret the hurt you did to me at that time. The cold and noble school beauties, the sexy and enchanting royal sister, the heroic policewoman, the charming teacher, the pitiful big star, the unreasonable and unreasonable lady. So what about the royal sister, what about the loli? Didn't you faint when you see my appearance? See how the new 12-winged fallen angel Lucifer once again breaks this hypocritical paradise and how to wander the city.
