Hardgore Alice from "Magical Girl Raising Project" by Alexa Cassaro

"MGRP" is a more recent horror magical girl story, focusing on a group of girls turned into magical warriors by a mobile game...

And then told there are too many and half of them will be killed to reach the desired quota.

Hardgore Alice was introduced later in the story as a new magical girl with the power to revive from any injury. ANY injury. No matter how bad. No matter if Alice is reduced to a puddle of blood and guts, she WILL heal like nothing happened.

I found Alexa's artwork while looking through the artist's alley page on the con website and thought she was a good match for Alice.
