The Lunacy of Marchioness Glassred

Summary:

You guessed it, this is the 100th roleswap AU out on the internet. The Lunacy of Duke Venomania but Gumina is the one with the sword . However, I wanted to try to do it while changing as little about the characters' backstories as possible. Cherubim was still born deformed and locked in the basement until Sateriasis convinced their father to let him out and then met Gumina and fell in love with her over time. And this is where the first change occurs: Sateriasis also falls in love, not with Gumina, but with her retainer Carol. Because of this the two remain close and Gumina manages to convince him to try and get his father to call off their engagement, revealing that she is in love with Cherubim. Unfortunately, she doesn't know someone has listened in to their conversation: her father. He isn't willing to let his plans to elevate his family fail because of one disfigured boy and plots to assasinate him. His daughter finds out and, in a fit of rage, she murders her father. Realising what she's done, she attempts to kill herself, but IR arrives and stops her, offering her a sword, which she claims will allow her to make her dream come true. Unfortunately, she neglects to say it will make her lose track of what that dream is.

Notes:

I DON'T OWN ANY OF THE CHARACTERS, THEY BELONG TO MOTHY AKUNO-P.
My English might be a little lacking at times, but that is due to me being an Italian struggling to find Evillious fans in my own country.
I might do the other sins too.
By the way, the Sateriasis in the relationship is Cherubim. He and the real Sateriasis are both in the story, but ao3 wouldn't let me list Cherubim as a character.

Chapter 1: Love and guilt

Chapter Text

"Kill Cheri? Father, how could you think to do such a thing?"
Gumina cried grabbing her father's arm. They were in his study, right after she'd overheard his conversation with his most loyal servant. He coldly shook her off. "That boy's making you lose track of what's important, Gumina! It's in the family's best interest that you marry Sateriasis, and if elevating our family requires one worthless boy out of the way, so be it!"
She couldn't believe her ears. Sure, her father was ambitious and a bit cold at times, but to think of killing Cherubim to get his daughter stuck in a loveless marriage...
The Marquis kept talking, but she couldn't hear what he was saying. His words were all drowned out by the rage that had taken over her. She was sick of it all: being controlled, her intelligence being ignored, being regarded as little more than a pawn by her own father...and why? Because she was a woman?

"And so" Claster continued "You should consider this a duty to the family and to yourself as well, what would everyone think if you, a marquis' daughter, married an ugly worthless servant boy? One day you will see-"
He never got to finish that sentence. Gumina had been pushed past her breaking point. Before she knew it, she had grabbed a book from the shelf behind her, a big volume on the arts of politics, heavy enough to deliver a fatal blow to someone's head. Having lost her temper, she struck her father with it. Claster fell to the ground not moving, his neck twisted in an unnatural angle. His daughter stood above him with the object that had ended the marquis' life in her hands. For a moment she was silent. Then she fell to her knees and burst into tears.
