Belphegor

Belphegor is the Avatar of Sloth and is the youngest and seventh sibling among the seven demon brothers. He is one of the main characters in Obey Me! recognizing his portrait that he admitted his identity. Additionally, it's mentioned by several of his brothers that he has the ability to manipulate them as well, using this ability to get out of things he finds tedious. He is supposedly a yandere character. This is based on the title of his Japanese card "The Yandere Seventh-Born" ("The Catnapping Seventh-Born" in English). As seen in both the Devilgram Searching for Jack and in the chat Belphie's Artistic Skills, Belphegor has no artistic skill.
