I aint a novel reader. I just buy the physical volume and read both online and it. I also heard about a spin off starring her sister in this same fantasy world. Five people have been taken out and one of them is still alive. When Yui-chan dies it will be six left.
It is the male who isekaid into a female. The story is about a killer who kills the dangerous reincarnated per request of the goddess of the fantasy world.
I feel like some of the reincarnated have a certain set of skills they acquired. Ende and Sato both have some sort of transportation ability. One disintegrate to appear wherever he wants while the other opens portals. Hyper-fast reaction time might be something they all share. They all still...
I am gonna say her powers are that from zombie films. Starting a zombie plaque and reattaching body parts whenever she needs it. I think the erasure of her deeds were from the potential danger of a zombie outbreak.
