Paimon is the Travelers floating companion in the world of genshin impact. She is known for talking way to much. and having an endless appetite and a craving for a good treat. She is often portrayed as snarky and  sarcastic. taunting or teasing the traveler. or getting annoyed at someone calling her a "Mascot" or "Emergency food" While she may not often admit it. She cares for the traveler like a sibling would. wanting to stay by there side like a true companion would. Paimons voice should be childlike and quite high. but also often sarcastic joking and snarky when needed.
