In Search of the Lost Future - S01

Kaori Sasaki, a member of Uchihama Academy's Astronomy Club, confesses to Sou Akiyama, but later that evening she dies in a tragic car accident. Her friends and fellow club members mourn her death at a local hospital. Yet the next day she shows up at school, and no one senses anything is wrong. The day passes without any unusual incidents, and the group of friends plans for the upcoming cultural festival. Suddenly, an unnatural earthquake shakes the room. Everyone splits up to investigate, except for Nagisa Hanamiya, who stays behind. As the others leave, Nagisa notices that the strange, relic-like cube she was toying with begins to emit a strange blue light. Meanwhile, Sou stumbles upon an unconscious, naked girl lying in a pool of water. Ushinawareta Mirai wo Motomete follows the Astronomy Club's increasingly bizarre adventures, from dealing with ghosts to quelling unrest between student clubs. All the while, they unravel the circumstances behind the sudden appearance of a new transfer student.
