Rokugatsu no Time Machine (2025) - Kissasian

As the town broadcast announcing the opening of the festival rings out, high school student Kashiwagi Aoi meets his childhood friends Ryusei, Issa, Momoka, Midori, and Akane for the first time in a long time.

“Tonight, Naozumi will be killed–” Ryusei tells everyone, and Aoi and the others are unable to hide their shock. Ryusei witnessed the death of his childhood friend Naozumi, and activated the time machine in the basement of his mansion, returning to the “present.” Furthermore, it turns out that all six of them, including Aoi, have experienced a time leap… In order to prevent the “future death of their childhood friend,” Aoi and the others repeat the time leap and get closer to the truth of the incident.
