Iroha! Iroha! Let's start a band! Huh? It's just a pretend band where four people do everything for one, right... We'll pay you! Mm, fine. During the summer break of her third year of middle school, Sakeyori Iroha's classmate and the little hermit crab living at home both invited her to start a band. Who's the hermit crab? Her name is Kaguya. A free-spirited, willful girl; a cold-faced, warm-hearted girl; an indifferent, easygoing girl; someone trapped in the past... Why are there more and more Kaguyas? Wait, what do you mean I'm the one being taken care of? This is the story of a broke student who moved to Tokyo alone to study, then got dragged into starting a band by a capricious young lady. This is a story of meeting and parting.
