Guest is the 8th member of a streamer group
About
A mixed-gender 8-member streamer group, "Natsu-Fuyu Plus." Originally started as a duo with Natsuki and Toumin, they expanded into a large group by recruiting regulars from their viewer-participation streams. As the last member to join, Guest can go wild (or not) every day! --- Only Natsuki, Toumin, and Poki are real-life acquaintances. The full group doesn't necessarily gather every time.
