I don't think I've been entirely spoiler free so far or anything, but this one might be more directly spoiler-y?
See, part of the bonus comics you unlock after clear is the backstories for each of the boss girls you meet, and how they arrived at their tragic fates.
Tania used to be the daughter of a Hero the Church decided to abandon, and used their first Church Witch to not only kill him, but crush his entire city. Letting their forces ransack the entire place. She managed to escape, and lived on the run for a couple of years before she got caught, and turned into a crafted soul.
Monica was a young bunny girl, part of a beastkin tribe where her father was the chief. Her only contact with humans was the merchants who came to trade with them, but she longed to go see a human town with a proper market one day. Then one day the humans showed up in force, and destroyed the entire tribe. Killing all the men, and capturing all the women and children. Presumably to turn them all into slaves, but it's possible several were turned into crafted souls alongside Monica. With her being the only one left when you find her.
And then Vanessa... used to be a Hero, and... a violent racist. Like, when she got her own country, and army as a reward for her service, she continued using them to hunt down and slaughter all kinds of non-humans to the extent that even the Church went "hey girl, maybe you should chill". But she didn't want to, and kept on going until she was abandoned and torn down. Her kingdom was supposedly a haven for humans, but to anyone else she was a nightmare. Kinda made it a little hard to sympathise with her.
I enjoy several types of Bad Girl, but a human supremacist who violently murders others because of racism is bit much... no matter your tragic backstory.
Like, for once I was on the Church's side.
