Coincidentally, Sarvente met Ruv as a child and they both became childhood friends. Despite having knowledge, she was still childish. These unfulfilled childhoods did not allow her body and mindset to adapt to the concept of growing up which is how she gained immortal-like abilities. Sarvente lived as a demon child for centuries not being able to age due to unfulfilled childhoods. It is unknown how Sarvente came into existence or if she had any biological family members or relatives. However, she also shows annoyance after she was defeated by Boyfriend in the Parish level. Sarvente is shown to have an enthusiastic, friendly, and calm personality as shown in Parish during her conversation with Ruv on the phone and welcoming Boyfriend and Girlfriend to the church at the start. In her demon form, she wears a leotard, has horns, and large purple and pink wings which come down from her hat. In her animated idle pose, her right hand twitches even further. Her color contrast is also slightly darkened as well. When she is annoyed, she beings to sweat and her expression starts to look irritated.

Her expression is passive and calm as she smiles. Her skin has 3 colors: Purple, White, and Pink. Sarvente wears a purple nun outfit, with 2 Pink crosses on the sides of her head. Sarvente (Sar-vent-tay) is a 'nun' at a church, where Boyfriend and Girlfriend walk in for the bathroom, and she asks them to join the church, in which Boyfriend and Girfriend decline the offer, and they end up battling.
