Drifting Classroom (or Classroom Adrift in the Galaxy)

A school building that carries the dead and drifts to various places around the world. This place of learning was called the "Galactic Drifting Classroom" by the dead 'students' who attended it. Every three days, the school building randomly drifts ashore somewhere. When the 'students' leave the school and remain in that place, they 'graduate' and are reborn to walk their next life. Chitose, a girl unable to begin her next life due to her lack of attachment to living. Yuri, the "class representative," looks after such a girl. One day, the Galactic Drifting Classroom drifts ashore in Sakuragicho, Yokohama City. Yuri shows a shaken expression as she gazes at the Minato Mirai scenery visible from the classroom window――.
