Music streamer Akagi was worried that his channel subscriber numbers weren't growing at all. Just as he was anxious about what to do, he heard about a "doll that grants wishes" from his former teammate Shiraishi, who is now a very popular cooking streamer. It is a magical doll called "Buau" that was passed down among ethnic minorities in Africa. If you use this doll to perform a ritual, any wish will be granted, but it demand something appropriate in return. Akagi calls out to Kurotani, Aoyama, Midorikawa and Shiraishi, who used to work with him as part of the streaming group "Five Colors," in order to carry out the ritual.
