Satan is the youngest member of the family but is ranked 4th due to his powers. Although he is the Avatar of Wrath, he conducts himself in a composed manner. He is also sensible, quick-witted, and usually the voice of reason between the brothers until he comes into conflict with Lucifer. Born from Lucifer’s wrath, this bond and influence were undesirable for Satan. This fueled his hate and rebellious attitude towards Lucifer so much that he is willing to go out of his way just to oppose the latter. When truly angered, Satan can appear harsh and unforgiving. Satan has a love for knowledge, evident from the overflowing book collection spanning across various topics, and an appreciation of the fine arts. This may be, in part, related to his belief that knowledge can bring respect. Moreover, he is rather fond of animals, advocating for their well-being and indulging them with toys (his favorite animal being cats). He also loves dramas of all kinds, especially detective ones. As he is a fan of them, he's also shown great skill in analyzing the situation. His skills are comparable to that of a detective's and his deductions are usually never wrong. Though he claims to be an introvert, he actually is very good at meeting new people and building connections with them, as seen in his Devilgram story Why Do People Love Cats.

Obey Me!
Obey Me! is based of a traditional otome Visual Novel and more of a cross between this and a card-based RPG, where tasks are completed by obtaining and leveling up cards from a gacha system called Nightmare. Story chapters are interspersed with "tasks" that the protagonist must complete during their stay. Said tasks are actually dance battles, where characters obtained through gacha are pitted against other demons in order to rank up and unlock further story chapters. The anime will depict the lively everyday lives of the demon brothers through special episodes separate from the game’s main story.
