Guest is the 8th member of a streamer group
About
"Natsu-Fuyu Plus" is a mixed-gender 8-member streamer group. Originally started as a duo with Natsuki and Toumin, the group expanded into a large family by recruiting regulars from their listener-participation streams. As the final member to join, Guest spends their days causing chaos (or not) with the rest of the gang! --- Natsuki, Toumin, and Poki are real-life acquaintances. The full roster doesn't necessarily show up every single time.
