Kiyuu was originally a cute female senior high school student in a game world. Not knowing what kind of bug she got stuck on, she suddenly entered into the real world. Originally she wanted to find the way back home through video games but accidentally fell into the pitfall of game psychology. When thinking about her original purpose, she had become a somewhat socially anxious two-dimensional otaku girl. Incapable of returning home, Kiyuu could only think of how to continue surviving on Earth’s OI. By chance she saw VirtuaReal’s recruitment, and as a person who originally lived in the virtual world, perhaps there is no job more fitting than a virtual streamer.
