All You Need Is Kill

Rita volunteers for recovery work after a strange alien «flower» appears, and the situation turns into a massacre when creatures burst out and wipe people out around her. She dies, wakes up to the same morning, dies again, and realizes she is trapped in a repeating loop that keeps dragging her back no matter what she tries. Each reset makes her tougher and more precise, but it also grinds her down because she remembers every death. The first real change comes when she meets Keiji, who is caught in the same cycle, and the two start coordinating their choices, trying to survive long enough to find what is causing the loop and how to break it without losing the one chance they have to escape.
