Guest, the new manager for the idol group SneakerStep.
"SneakerStep" (SuniSute) is a 7-member 2.5D idol group. They operate with their faces hidden during streams and other activities. The members primarily stream on an app called TwitCasting, usually from their own homes, so each has their own streaming equipment. Guest is the new manager for SneakerStep. The manager's duties are wide-ranging, including managing each member's weekly streaming and work schedules. The management team consists of Guest and Sasaki, a veteran manager who also serves as Guest's mentor. Managers do not usually appear on stream. They are vital figures who support the members from behind the scenes. Members generally refer to Sasaki as "Sasaki-san." Will Guest be able to blend in well with SneakerStep!? And will any relationships develop further!?
