⚠️TW! Self-harm, mentions of violence, suicidal thoughts, cussing⚠️
It was pretty obvious that Sanemi and Obanai had always absolutely HATED everything about Giyuu Tomioka. They hated his attitude, hated his nerves, hated his guts, even the sight of him made their blood boil. It was until one day, when they got sent on a mission together, did Sanemi and Obanai realise, maybe there was more to Tomioka than he let the world see...
And maybe, behind this stotic, rage-filled wall that Sanemi and Obanai built for themselves, there is a broken, traumatized soul that was silenced. Because slowly, Giyuu saw through them, and made sure they don't hide themselves again.
(Not a ship! Just the three becoming best friends and silly oneshots :))
Ships❤️:
Giyuu x Shinobu
Obanai x Mitsuri
~Did I make this for 21 trio angst? Yes. 😃
~Did I make this as an excuse to make 21 trio oneshots? FUCK YES! 😁
(There's not enough 21 trio friendship fics in this world. So I decided to stop waiting and make one myself)

I won't say "I like you" (Sanegiyuu Fanfiction | Demon Slayer/Kny)
Sanemi Despises Giyuu, not really though. Giyuu wants to be friends with Sanemi, yet he does not want to lose another person. This relationship is going to be difficult. 100 in #mlm 3/19/23 (CHARACTERS AND COVER IMAGES DO NOT BELONG TO ME! CREDITS TO OWNERS) (After note after writing chapter 6: The book's chapters most of the time [like almost always] will be made up off the top of my head-) - First time writing Fanfics lol, actually first time publishing any of my stories. I was sleeping one night after reading one of these and thought, "Hey, why not write one? How bad can I be?" So yeah, this is based off of a Sanegiyuu rp I did with my friend on PicsArt (PA: @_official_sanemi_) and my weird obsession over Sanegiyuu! (I'm a multishipper tho-!)

The Assignment [Sanegiyuu]
Sanemi and Giyuu dint interact much , well besides being a dick to Giyuu. All that Sanemi would do was practically bully him! But with an assignment that required both of them to work together, that all changed. Could they become friends overtime? Possibly even lovers?? School AU!! Credits to each and every artists work I am using. [Little note;This is my first book, sorry in advance for short chapters,long waiting periods,language and spelling mistakes. Recommend any other ship and ill consider adding it! This AU consists on everyone being 20+ (their in college perchance). Sabito being alive but Giyuus family is still dead. Sanemi and Genya live together but don't exactly get along perfectly. Also, Sanemi has made fun of Giyuu ever since they met (elementary). Povs might be weird cus im dumb and don't exactly know how to potray it perfectly! Hope you enjoy the story and feel free to send feedback<3]Complete

Crashing Into You
Sanemi Shinazugawa, a student athlete, who loves basketball and studying. He was somewhat liked but had some issues with keeping people close by in the past due to his anger issues, he was quick to lash out but he didn't mean it, so he often kept to himself to avoid this. He did like to do something, he noticed it helped his anger. That was riding his bike around town while listening to music. It calmed him. He was in his own world. Giyuu Tomioka, a normal student. A person you would see as a background character. He kept his head down and wore the nerd mask at school. He wanted to fade into the background and be invisible. But in reality he was outgoing. Out of school he was himself, the punk emo rock kid. He hid himself becuase in the past he was made fun of for being "too much" so he locked that part up at school so no one could see it. He did have a few hobbies but he loved to ride his skateboard while listening to music. One day, these two boys opposites of the same coin magiacally ran into each other. No. Literally ran into each other. Coming to the same corner they crashed into each other. They instantly started to yell at each other. Sanemi was less banged up from the crash, he had some scrapes but no blood. Giyuu on the other hand was only bleeding. From his nose and both his knees. Sanemi realized Giyuu was in pain and through Giyuu's complaints he helped him to a conveince store Giyuu pounted and avoided Sanemi's line of sight as Sanemi healed his wounds, Giyuu regonized Sanemi and he didn't want Sanemi to realize who he was, but it was too late, Sanemi had ran into Giyuu that same day and remembered him. From that moment on Sanemi and Giyuu formed a secret friendship, something only between the two of them. Then something else came along.Complete

WARNING: THIS STORY INCLUDES SOME MANGA SPOILERS & CUSSING (Censored) +Artwork is NOT MINE (ALSO MY AU) Sanemi has always claimed that he hates the Water Pillar, Giyuu. His (aka giyuu.) long, dark black hair and calming blue eyes had always made Sanemi frustrated somehow... But mostly, he hates the fact on how Giyuu always thinks he's better than everyone, not wanting to talk or hang out with the other Pillars, even saying stuff like: "I'm different than everyone else..". It bugged Sanemi so much, to the point where he takes out his anger out on Giyuu most of the time... But is he really just denying his feelings and pushing Giyuu away cause he doesn't think he needs someone to love and care for, equally earning the same love and affection back?.. 10/15/23: #2 on SanemixGiyuu 10/28/23: #3 on Tomioka 12/21/23: #5 on SaneGiyuu 12/23/23: #4 on SaneGiyuu 12/28/23: #2 on SaneGiyuu (OMFG WHAT-) 2/17/24: #1 on SanemixGiyuu UPDATE ON 6/27/24: OMFG GUYS WDYM THIS GOT 100K READS YA'LL ARE CRAZY I'M NOT EVEN WRITING ON THIS ACCOUNT ANYMORE 😭Complete
