“This is fine…”

Nice of you to ask! It’s an illustration of my Blades in the Dark (ttrpg) character! Over the course of the game she became more and more unstable, while also falling in love with someone and wanting to protect them at all cost. At a point she became too horrified of her own brutality, scared she would hurt that person. So when they were fleeing through a field of death fog, she stepped back into it just after everyone got out to eliminate herself as a source of danger.
