Adapted from the novel of the same name by Yoshiyuki Sakura, this project is crafted by the dream team STUDIO4 °C , known for works like " Tekkonkinkreet " and "Children of the Sea." The popular voice actors from "Demon Slayer," Natsuki Hanae, Ai Mikami , and Kana Hanazawa, lend their voices to the characters. This gripping sci - fi epic follows Rita (voiced by Ai Mikami ), a young soldier whose world collapses when alien invaders decimate Earth's defenses. Alongside fellow warrior Keiji (voiced by Natsuki Hanae), she becomes trapped in a merciless time loop — forced to relive the same devastating battle, dying repeatedly in ever more excruciating ways. Each rebirth brings new horrors as their minds and bodies reach breaking point. But when their paths finally cross, a desperate strategy emerges from the cycle of destruction. Their fragile alliance could be humanity's final hope against extinction
