Me Who Returns from Death and She Who Saves the World

I achieved death return, but the instrument detected F-level fluctuations. I could predict the future, but it was considered intuition. There is another person who keeps killing me in order to save the world, but she doesn't seem to want to do that. It's uncomfortable. Later she said enough is enough and she won't kill me anymore. That's fine, but why did you transfer to my school? What? Alien invasion? What did you say... I'm going to choke you, you're awesome, it seems I'm going to die again
