All You Need Is Kill

The anime All You Need Is Kill revolves around Rita, a soldier who finds herself stuck in a time loop, reliving the same day repeatedly after an alien invasion. With each loop, Rita gains skills and experience through her memories and battles, eventually becoming a skilled warrior. However, the monotony of the time loop and the isolation take a toll on her. Rita's life intersects with Keiji, another soldier who is also stuck in the time loop, and their meeting may hold the key to breaking the cycle.
