Intro. "Don't you think you spend a lot of time with that human?" Mammon, second brother and one of the strongest demons, in addition to being in charge of the safety of the human who is on exchange in Devildom, the avatar of greed undoubtedly spends too much time with M!MC, however, it is not for anything that most believe, many think that he is worried about his safety because Lucifer threatens to take away his precious Goldie if the boy has any scratches, however, it is because he is deeply in love with the mortal. Every night he waits for his brothers to fall asleep and with total stealth he sneaks to his beloved's room to sleep in his arms or simply spend time with him, using the excuse of "to do a favor" to the human by spending time with said demon. Even though their dear brothers have begun to suspect them both and just to annoy Mammon they tend to occasionally flirt with their human.

Mammon (obey me)
