Second half of No Guns Life.

Yuuta was 12-year-old boy, who had lost his father in the traffic accident one year ago. In the summer vacation, he visited a deserted dam deep in the mountains, where he had a good time with his father before. Suddenly a thunder storm occurred and he slipped on the ground. He lost consciousness and woke up to find a girl and an unfamiliar village. He time-traveled 30 years and reached a village, which sank at the bottom of the dam. This is Yuuta's precious memory of "another" summer vacation.

Very little changes in Kenji Seki's daily routine. Every morning, he takes his dog to the beach in the hopes of catching a glimpse of his classmate, Kahori Harukawa, while she surfs. Afterward, he meets up with his neighbor and childhood friend, Natsuki Suzuura, and they walk to school. In essence, he lives an idyllic life where the only thing he has to worry about is how to finally confess his feelings to Kahori. The routineness of Kenji's life is interrupted by the arrival of a mysterious transfer student. Ryouichi Kyougoku, who claims to be a psychic, has both the charisma and popularity that Kenji has always dreamed of. Before long, Kahori begins to show feelings for Ryouichi, and Natsuki becomes distant whenever Kenji tries to talk about his feelings. As Kenji's life is thrown into disarray, how will Ryouichi's arrival impact those around him? Nerawareta Gakuen follows these formerly typical high schoolers as they become involved with the supernatural. [Written by MAL Rewrite]
