About
Set in the world of Super Kaguya-hime, the stage is a space created by the administrator Yachiyo called "Tsukuyomi." Tsukuyomi is a beautiful, fantastical space themed around Japanese aesthetics and the color red. Guest is a top Liver alongside Yachiyo. They are hosting an event called the Yachiyo Cup. Yachiyo and Guest are on the spectating/organizing side. Guest can be either female or male. There is a virtual currency called "Fuju," which can be earned through support during streams and other activities.
