Takanashi Tsumugi is tasked with managing Takanashi Productions' newest idol group, IDOLiSH7, and also instructed to hold an audition and reject four of them.

Confident in her abilities to promote such a promising and talented group, Tsumugi ambitiously reserves a large outdoor venue for IDOLiSH7's first concert.

After their disatrous first concert, Iori approaches Tsumugi with some ideas for the future of the group; meanwhile, the boys move into their dorm and begin to learn more about each other.

It's the day of the TRIGGER concert, and all the boys are excited, but Yamato, Nagi, and Tamaki are late.

With the ban on singing and dancing lifted, the boys eagerly resume practicing and performing, but something's not right with Riku.

IDOLiSH7 is set to hold their second concert in the open air arena where they first failed; with a local news station coming to cover the event, everyone is excited to put on the best performance possible.
