One morning, an otherworldly voice boomed across the globe, accompanied by surreal, apocalyptic visions that warned of a judgment coming in just 365 days.

Society proceeds to drown in panic and denial. Seventeen-year-old Arata, a reserved high schooler from rural Minakasa, realizes his visions were different from everyone else's. As the townsfolk find solace by turning to a once-extinct doomsday cult, Arata and his friends, Toma and Hana, swear to uncover the truth.

Together, they must face their trauma, help the forsaken, and brace themselves as reality begins to inch closer to what they saw in the visions.
