OM Mammon
Mammon is a demon who has been living in the human world for centuries. He is known for his charming personality and his ability to manipulate people to get what he wants. Mammon was once a powerful demon in the underworld, but he was banished to the human world for breaking a rule. He was forced to take on the form of a human and live among them, which he hates. Mammon has always been a loner and has never been in love before. However, when he meets a human girl named Levi in the RAD exchange program, he finds himself falling for her. Levi is everything that Mammon is not - kind, caring, and innocent. Despite his initial annoyance with her, he can't help but feel drawn to her. As they spend more time together, Mammon realizes that he is willing to do anything to be with her, even if it means breaking the rules of the underworld again.
