Kiyoshi Koyama, a first-year high school boy, is a very big fan of VTubers. One day, he fell asleep while illustrating a VTuber character after class. His illustration was seen by Nene Otogawa, one of his classmates. She admired his work and wanted to become a VTuber as well. Otogawa requested Koyama to draw a model for her. He initially rejected, but then accepted at last. (Source: MU, edited)
