In front of Naishi, an introverted high school student living in Kyoto (voiced by Carpenter Kitamura), the 26-year-old suddenly appeared from 10 years later (voiced by Tauri Matsuzaka). The truth of the future told him that he would soon fall in love with glass (voiced by Hamamabe Meibo), but then she would die because of an accident at the fireworks display. In order to save his lover, the 16-year-old straight involved in this real and virtual memory world, experienced a series of unimaginable things. Even if the world ends, I still want to see you again.
