Based on an original concept by an award-winning novelist Inujun, the manga Teppen!!! is illustrated by Namamugi.
The unit consists of Mikoi Sasaki (Royal penguin in Kemono Friends), Aimi (Kasumi Toyama in BanG Dream!), and Ayasa Ito (Arisa Ichigaya in BanG Dream!).
It all started when the three members of Team Y performed manzai at an event in January 2019.
