Makina Oda has crash-landed into Eichou High with all the force of a shooting star, and Yotsuba's already fragile social life has been caught in the blast! It would be bad enough if Makina were just a nationally renowned idol who also happened to be Yotsuba's childhood friend, but the fact that she's also dead set on winning Yotsuba's affection has dialed the chaos—and awkwardness—up to eleven. Then, just when it seems like things can't possibly get any worse, the annual cultural festival arrives and Makina, Yuna, and Rinka are thrown together in a project that could bring all those conflicts to a head at the same time!

Can Yotsuba navigate the interweaving needs of her friends and girlfriends, the pressures of an oncoming festival, and her own crippling social anxiety to save the day and make everyone happy? Not alone, that's for sure! Where's Koganezaki to help when Yotsuba needs her most?!

No, really... Where is Koganezaki?
