On a seemingly ordinary August day, the entire third-year class at a Tokyo high school suddenly vanishes, along with their school building, and reappears adrift in a strange, otherworldly dimension. This surreal and philosophical anime follows the students as they discover they have been granted bizarre supernatural abilities, ranging from controlling gravity to communicating with cats. At the heart of the story is the quiet and observant Nagara, who awakens with the power to teleport to any "world" he can imagine, and the enigmatic transfer student Nozomi, who seems to know more about their predicament than she lets on. As the students struggle to survive and navigate this new reality, they are forced to confront their own identities, desires, and the fragile nature of their society. The series unfolds as a meditative and often dreamlike exploration of adolescence, isolation, and the search for meaning, where the line between reality and fantasy blurs with every strange new world they encounter.
