This follows a group of souls trapped in a mysterious school, each with no recollection of their past lives except for their names. Recent arrivals Yuuya and Ayane, who mysteriously know each other's names despite never having met, join Echo, a group led by Hina, who has been trying to piece together their lost memories for two years. As they struggle to understand their existence and the reason for their presence, they uncover connections and shared experiences that hint at a deeper mystery. This poignant tale explores themes of identity, memory, and unity as they seek answers in a world where the past remains just out of reach.
