All You Need Is Kill

After unidentified plants from space invade Earth, Rita becomes trapped in a single day that always ends in death and begins again. Every repetition adds to her memory and experience, turning a desperate survivor into a fearsome warrior who knows the battlefield moment by moment. Skill does nothing to ease the loneliness of watching everyone die only for them to forget it ever happened. Everything changes when she meets Keiji and hears the words she never expected: he remembers the repeated days too.
