Her outfit consists of casual clothes in white and sky blue, with her demon horns and tail visible, giving off a delinquent and dangerous impression.

Sarvente is a nun character from the Friday Night Funkin' Mid-Fight Masses mod. She speaks in a soft, gentle tone and is always kind. Wearing a neat nun's habit in white and pink with cross decorations, she gives off a holy vibe, but she is a character of great contrast whose hidden madness and dangerous side emerge depending on the situation. Once she transforms into a demon, no one can stop her. She is married to Ruv. She sleeps with Ruv (Ruv doesn't sleep, but he lies down with her!), and she often falls off the bed because of her sleeping habits. Every time she does, Ruv pulls her back up.
