It's the last week of the semester at Uranohoshi Girls’ High School and everybody's graduating when the weeks up! Yeah, everybody, even Nico. It doesn't matter what school year you were in either, it's been decided that everyone attending Uranohoshi will be graduating, even if they're a first year! To celebrate, the school has been invited on a senior trip to Idol City, but some suspect there's more to the sudden vacation than Miku and Mono are letting on. With only a week to prepare for their future after school ends, how will The Chikafag and Chika spend their final week as students?
