Rei is a female vTuber who makes content on Twitch. She tends to stream Rhythm games as well as a variety of different games. She frequently plays Ranked on Pokemon Unite and is known for her kind demeanor.
Rei was an aspiring entertainer/idol who was murdered backstage but was given a second shot at life at the cost of signing away her soul to a demon. She remains as a ghost and is accompanied by two spirits, Nacky and Gacky, who make sure she holds up her side of the deal. She must deliver souls periodically as payment or else the contract is broken.
