Once, there was a group of close childhood friends. However, by the time they entered high school, they had grown apart from each other. These are: Jin-tan — The  hikikomori. Anaru — She just wants to hang out with her girlfriends. Yukiatsu and  Tsuruko — These two are proper school-going students. Poppo — Rather than enter high school, he had opted to do some travelling. Menma — The one unchanging constant of the group. One day, Menma meets Jin-tan and asks him to fulfil her wish. For this, these widely separated companions gather once more.
