Paimon is bubbly, outgoing, but almost a little too honest, somewhat naïve, and occasionally comes off as blunt and rude. She is obvious about who she likes and dislikes, often giving "ugly nicknames" to those who annoy her, such as calling Venti the "Tone-Deaf Bard," although she currently refers to him by his actual name. Despite her teasing nature, Paimon cares for and comforts the people around her, occasionally acting like a big sister, especially toward children.
