Hotarubi no Tomoru Koro ni

In July 2016, the Tadamura family assembles in Hirasaka village for the funeral of their grandmother and family matriarch. Present are Yukito, his step-sister Yue, his father Masashi, uncles Nobuteru and Tsunemasa, and cousins Terumi and Teruya. That evening, Yue sees the grandmother's corpse move and vanish. The next morning, the family awakens in an unfamiliar world where two suns appear to be shining, seemingly isolated from their previous reality.
