On This Week's Episode Of Sadistic Writer Brain! - Tumblr Posts

Shizu really did stay out late that night, and Sanemi allowed Genya to go with him to search for their mother, leaving the third oldest in charge. In their absence, (somehow) the younger siblings were all turned into demons. As Sanemi and Genya return with Shizu, they are faced with their killing machine siblings, forced to kill them (Sanemi and Genya get their scars, whether Shizu gets any is up to you). Now Shizu and her two remaining sons embark on the path of demon slayer, and shenanigans with demon-eating-Genya ensue (as well as angst). Maybe Shizu also eats demons? That’d make for some cool interactions :)

Shinazugawa Trauma(🎀)

Gotta have that tragic backstory!

But what version?

Chances are whichever brother isn't the demon is gonna be the one to kill the demon brother. Sorry, boys! Context below the cut.

So, I'm working on Shizu's backstory. And since she's not becoming the demon Shinazugawa, someone else has to. Because this family is just trauma in a box, and cannot catch a break.

But I am stumped on which version to go with. I had considered having Shizu being the one to fight against/kill one of her sons as an option. But then I considered the sweet, sweet angst of her, seeing one of her oldest two sons wounded and fading away with his brother covered in his blood and standing over him, accidentally comparing the living son to Kyogo. And the utter devastation on both sides when that happens.

Characters in my fanfics never get peace until Muzan is dead...
