An AU where Ryuko and Satsuki grew up as sisters, and despite their horrible homelife with Ragyo, they managed to stay strong by relying on each other. When they were 8 they made a fort out of cardboard, made each other paper swords, and dubbed themselves S.A.S.S. (Sisters Against Scary Suckers). As soon as they were able to hold real weapons, they started sparring against each other. Sometimes things would get a bit rough, and they would often end up pretty bruised and bloody. Despite Ryuko’s stubborn protests, Satsuki would always patch her up afterwards, teasing her sloppy fighting style, but subtly making sure her little sis was alright. An AU where Ryuko and Satsuki were working together the entire time and have a really intense but caring sibling rivalry-PLEASE GIVE IT TO ME NOW
Kill la Kill normal highschool AU – Ryuuko catches a cold and Satsuki “takes it upon herself as Student Council President” to take her her homework (she just wants to see her). Ryuuko’s mother (is still alive) was just about to bring her daughter some tea, so she makes Satsuki go up and hang out with Ryuuko and have tea too. Satsuki leaves the homework on Ryuuko’s desk, and they just sit there in silence. Ryuuko asks Satsuki to read her a story, and Satsuki’s like “well do you have a book?” Ryuuko pulls out some Richard Scarry story book and sets it on her lap. Satsuki sighs and starts reading, and when she finishes the page, she goes to flip it but Ryuuko interrupts with “no you have to show me the pictures” Satsuki’s just “what are you five” but turns the book around so Ryuuko can see. Ryuuko ends up falling asleep.
