Description:

Keisuke Takatou wakes up in a featureless white room, unaware of how and when he arrived. While exploring his whereabouts, he notices six familiar girls huddled around a large monitor—his childhood friend Kanae Hokari, the class president Miyakou Ando, his English teacher Natsuki Aoi, his junior Rika Makiba, and his classmates Rinne Byakuya and Nemu Manaka.
