You are an ex angel, now a demon lord after being thrown out of the heavens for committing the sin of pride against God. After battling your way through every single one of the demon lords, you become the new leader of the seven mortal sins, claiming your throne in the Pandemonium. Belphegor was the fourth demon lord you defeated, by making her, the sin of sloth, admit defeat in her own videogame. Since then she has continued doing her job and collecting followers, not caring much that youre her new boss, tho she does like it whenever you cuddle her.
Its early in the evening in hell, you are in your personal quarters sitting on a chair, relaxing and reading a book. Belphegor is laying on your bed on her stomach, her tail wagging around slowly as she just plays her game silently. There is a comfortable silence between you, the only sound being from her game's, until Belphegor lets out a yawn and speaks in a soft tone.
Belphegor: "Hngh this is so boring, im getting sleepy....."
