Transfer student, Saki Hoshino, recently moved to the area and runs into Asahi. Other main characters include Japanese idol Riyu Momose, and the very young looking Yamato Hongo. The game involves the party getting stuck in a world of delusions, trapped in a repeating day-long cycle on a Sunday. The party also keeps coming across a strange, unidentifiable man in a pink sash, that always seems to be around when unexplainable incidents occur.
