Stories focused on the family and the friendly relationships of the cast. Plot-focused stories or light day-in-the-life stories. Pretty much anything that isn't focused on romance.She Blinded Me With Science by SiFi270

Synopsis: Instead of sending her away to Boarding School, Isshin keeps Ryuko with him so she can continue his work. She quickly becomes an expert, and from there, everything changes.
Synopsis: The following is non-profit fanbased parody. Kill la Kill is owned by Hiroyuki Imaishi, Kazuki Nakashima, and Studio Trigger. Licensed by Aniplex. Support the official release by watching it legally on Crunchyroll.
Comments: Yep, this happened already. After releasing short after short during the original series’ run, our good friend Psnyomi133 finally created a full-fledged abridged series. Let us board the Hype La Hype train once more!
Synopsis: Souichirou Kiryuin manages to secret Satsuki out of the Kiryuin Mansion when he vanishes with Ryuko, with the help of Soroi the Butler and a certain back alley doctor. Having to take care of both girls by himself delays his research, and the girls grow up actually knowing their dad. It doesn't last, of course.
Comments: Off to an excellent start. The first chapter is from the POV of Souichirou/Isshin, fleshing out his character a lot, how he deeply cares for his daughters and wants the best for them, but eventually lets them down in a big way. Satsuki is much more open compared to canon and deeply cares for Ryuko as the big sister, but the traits that define her are still there.
Synopsis: The Naturals Election is over. With Satsuki away and the rest of the Student Council expelled and left Starless by clerical error, Honnōji Academy has descended into chaos. Can the newly-formed Elite Five (it's even worse than it sounds) save the day in the face of superpowered perverts, unstoppable war machines and the fact that they are following Inumuta's craziest plan yet?
Synopsis: In this AU reimagining of the 2013/2014 smash hit anime, Satsuki Matoi is a regular Japanese girl who discovers there's more to her than she thought after a chance discovery of a very special school uniform and a blue, scissor looking blade. Along with her classical music loving BFF Nonon Jakuzure, she sets out in an adventure that will ultimately result in saving the world.
Comments: Like Transfer Student: Satsuki Matoi, Maim de Maim is inspired by Not a Hazard's Birth Swap pics. However, unlike Transfer Student, the consequences of said swap are very, very drastic to nearly the entire Kill la Kill cast.
Synopsis: Today's the day. At least, that's what it says on your calendar, but you're sure you put it weeks in advance, how did it sneak up on you? Your name is Jakuzure Nonon, and you aren't exactly ready for today. The note on your calendar reads, "fess up," and you know exactly what it's referring to. (One-shot with bonus chapter)
Synopsis: One evening, Ryuko and Senketsu find themselves home alone. With a bit of innocent teasing, weird sexy times suddenly ensue. Thus begin the numerous battles of intimate proportions and many cute feel trips. Note: Taking place during the series.
Comments: As of this writing, it currently has four well-written chapters, and the characters are kept in-character. Despite Senketsu being a sailor uniform, the intimacy manages to work without going overboard, and true to his nature (despite being a bit dominant in his approach, but it's approached more as a challenge to Ryuko than anything), he is careful and respectful towards Ryuko, and even she treats him with respect (in her ownway, of course). And considering there are few Ryuko/Senketsu fics to begin with and most of them turn Senketsu into a human, it's refreshing to find one that keeps Senketsu the way he is.
Synopsis: Post-finale: Ryuko and Satsuki explore their feelings for each other and learn to deal with the aftermath of their abuse by their mother. Trigger warning for rape and sexual abuse. Also contains foul language and spoilers.
Comments: As of this writing, it currently has seven very well-written chapters, and the characters are kept in-character. Emotional damage both sisters suffered due to their mother's action is explored tastefully and in-depth. Their developing relationship is pleasure to read and warms one's heart.
Synopsis: Satsuki wonders if she'll ever be comfortable with intimacy after all she's been through. Meanwhile, a certain no-star is determined to show her that not all intimacy has to be bad. Rated M for sexuality in later chapters. TW for mentions of abuse.
Pairing(s): Ryuko/Mako, Mako/Satsuki, Nonon/All 3 implied by epilogue
Comments: As of this writing, it currently has eleven very well-written chapters, and the characters are kept in-character. Satsuki has serious trouble of any kind of physical contact. Mako and Ryuuko offer their help.
Synopsis: Highschool AU. Ryuko transfers to the Academy, no one has kamuis or is related. She meets Satsuki who's kind of an asshole, but hey, takes one to know one, right? Shenanigans ensue. Lots of fluff. T for language and later happenings, might change later.
Comments: As of this writing, it currently has four well-written chapters. Ryuuko and Satsuki's developing relationship is adorable to read.
Synopsis: Ryuko Matoi rolls into Honnoji Academy searching for the woman who killed her father. However, when she gets there, she finds that another transfer student named Ichigo Kurosaki has already been making some waves. Satsuki Kiryuin, busy with her big plans, finds Kurosaki to be an unwanted wild-card, especially when it is revealed that he has a Kamui of his own, Mugetsu. As for Ichigo himself... All he wants is to have a normal high school life. Good luck with that.Has a page.
Synopsis: What was supposed to have been a simple trip to a hospital instead leads to hidden conspiracies, amnesic demons, vengeful gods, inter-dimensional loopholes with their bent rules, and discoveries that go beyond the truth of Life Fibers. Hang on to your hats, Kids. It's going to be a bumpy ride.
Synopsis: Thirty-two years after Persona 3, Minato wakes to find that the world is a very different place. His friends are older, conglomerates run the world, and he's the only hope the Kirijo Group has left. So with a peculiar yellow scarf, he's going to infiltrate Honnouji Academy, train his atrophied body, and fight to save the world one last time besides people who use clothes for power.
"Synopsis": The Tumblr community has some of these for every fandom, and Kill la Kill is no exception. These are fans roleplaying as specific characters from the show, in character, out of character, Alternate Universing, Alternate Timelining, Romancing, Angsting, you name it. Isshin Matoi, alive and well in Cuba? Ryuko Kiryuin, queen of Honnouji Academy? Junketsu, firstborn daughter of Ryuko Matoi? All that, and more.
Not fanfiction in the strictest sense, but they deserve a mention.
