Evil God Reincarnated: From the Start, in the Noble Academy Girls' Bathroom

I'm Kira.

I was once a legendary assassin, and countless heroes fell to my sword.

Some called me despicable because I always relied on ambushes and assassination. I never argued. That was how I survived. It may not have been glorious, but it was how my legend was written.

After I died, I met a goddess, not the one I knew, Alicia, but a being of a far higher order.

She told me I would be reborn as a safeguard, to prevent Alicia's world from collapsing.
