After being officially acknowledged as a club, Chika, You and Riko set their targets on their underclassmen. Ruby, however, is afraid her sister will not allow her to become a school idol, while Hanamaru is convinced a country bumpkin like her could never be one.

The chairwoman of Uranoboshi High School makes herself known and promises Chika, You and Riko the school will acknowledge their idol group if they manage to fill up the entire auditorium for a performance. Though initially euphoric, the girls soon realize that getting the entire school to attend will not be enough.

Despite having met over half a dozen potential new members in the span of a single episode, Chika still hasn’t come any closer to realizing her dream of starting her own school idol group. When Riko refuses her offer for the umpteenth time, Chika and You set out to help fix whatever it is preventing the transfer student from joining their club. By any means necessary.
