The Evil God Is Reincarnated, Starting in the Ladies' Room of the Noble Academy

I'm Kira. I was once a legendary killer, and countless heroes fell under my sword. Although some people say that I am despicable because I always carry out sneak attacks and assassinations, I never refute it. This is my way of survival. It may not be glorious, but this is how my legend is written. After death, I saw a goddess, not the Alicia I knew, but a higher-level existence. He said, I will be reborn and become an insurance - to prevent Alicia's world from collapsing.
