Kurase Sora was a TS reincarnator.

Ten-plus years after reincarnating, Kurase Sora, now a high school student, was using her summer break to play a popular FPS game with redmoon, a friend from high school.

While helping redmoon rank up, redmoon suddenly falls asleep.

Kurase Sora somewhat continued the game, but it turned out redmoon was a super popular Vtuber.

Her peerless performance, while single-handedly covering for her sleeping friend, was broadcast worldwide... and on top of that, she ends up becoming a Vtuber...!?

Thus begins the Vtuber life of this TS girl!
