Modern AU. The Hashira and Kamaboko squad are all students (apart from Gyomei who is their friend outside of School.) Giyuu doesn't do well at school, he has long term hypothermia from when he got lost on a mountain in a snowstorm as a kid and left unconscious for weeks, almost freezing to death. If it weren't for Urokadaki, he would have died. But now the consequences get worse. Shinobu bugs Giyuu as she discovered this quickly. But theres an angry guy who will get in the way of them.. i wonder who 😭 MAIN SHIPS: Sanegiyuu, Shinogiyuu +others WARNING! ⚠️ spoilers.? - angst, blood, sh, swearing .. illness... sensitive topics etc - cringe, canon and non canon ships! NOTE: IM NOT A DOCTOR!! please note some stuff in here is probably not accurate.

this is a saneobagiyuu story, MY AU may contain smut later on, so read at your own risk this takes place in the future, modern era (all hashira were reborn after they all died) takes place in tokyo (but i've never been there so please don't get mad if anything is wrong 😅) rankings: #1 saneobagiyuu as of 1/23/2026 #1 giyuu as of 2/10/2026

so.. this was gonna be the og tea but I changed it and so basically it's very early like when Giyuu's still 18 but met tanjiro already, and Sanemi is 19(his older in my au:3333) and Giyuu basically accidentally slept with Sanemi and yk omegavese or mpreg and you'll understand it at the prologue Oh and Giyuu and Kokushibo are friends like best friends in this au Giyuu's gonna be a single parent for awhile(did not tell Sanemi he was gon be a Father that's why)

~OBAGIYUU: MARRIED AT FIRST SIGHT AU~ Obanai Iguro didn't sign up for this. Well, technically he did - but only because his best friend (Sanemi) wouldn't shut up about it. Now he's about to marry a stranger on live television. Giyuu Tomioka didn't sign up for this either. His best friend (Mitsuri) signed him up while he was feeding cats. Two introverts. One reality show. Zero idea what they're doing. What could possibly go wrong? (Spoiler: everything. And maybe...something beautiful.) !!! Updates will probably be twice a week! !! I do not own the show "Married at First Sight". Credits to the creators; it's amazing! !! I do not own cover image; Credits to the artist💖

A year and a half has passed since Sanemi Shinazugawa left for training, pursuing his goal of becoming Chief of Police. Now, with his return to Fuji, he's ready to reunite with the two people he loves most-Obanai and Giyuu. But time apart can change people, and despite his determination, Sanemi can't help but wonder: Do they still feel the same way? As the three navigate their deepening love, old feelings resurface, unspoken emotions come to light, and a future together starts to feel like more than just a dream. But with career ambitions, lingering insecurities, and the weight of their past lives still influencing their choices, the path to happiness won't be easy. READ INFO!!!

When Giyuu Tomioka is reincarnated into the new world, he regains memories of his past life as a stoic and depressed Hashira. Now moving to the bustling city of Fuji, Japan, Giyuu's quiet life is suddenly turned crazy when he unexpectedly crosses paths with his former comrades - the Hashira. An unexpected romance forms with the very two Giyuu thought hated him most: Sanemi Shinazugawa and Obanai Iguro. ~Together, the three former Hashira experience complex emotion, lustful desires, deep secrets, and heartfelt romances.

~A Sanemi x Giyu story (biologically female Giyu) ~ SPOTIFY PLAYLIST: https://open.spotify.com/playlist/3QwYn27bHAuOusVaLveZQ7 _______________________________________ Tomioka Giyu's always identified as genderfluid, but since becoming the water hashira everyone's always assumed "he" was male, though he never cared enough to correct them. ..."He" had bigger problems to deal with. No one even knew that Giyu struggled with depression, suicidal thoughts, and gender dysphoria for years - all while working along side the wind Hashira Sanemi Shinazugawa. Shinazugawa is rough, aggressive, and loud, but when he finds Giyu standing at the edge, the facade falls. ~∞Will Tomioka find a reason to continue on, or will a reason find him?∞~ _______________________________________ ∑• CONTAINS: - Lgbtq :) - Genderqueer :) - Fluff 🥹 - Smut 😏 - Self-worth issues :[ - ⚠️Suicidal thoughts ⚠️ - Enemies to lovers 😏 _______________________________________ ∑• RANKINGS: - Best ranking: (6/14/25) #2 in yaoifanfic (out of 11.2k stories) - (4/10/25) #1 in sanegiyuu - (4/19/25) #5 in demonslayer - (4/18/25) #5 in lgbtqromance - (5/20/25) #10 in giyuu _______________________________________ Vote, comment, and if you enjoy, follow and read my other stories :) *Published February to March 2025, edited October to November 2025 _______________________________________ [I DO NOT CLAIM OWNERSHIP OF ANY OR ALL KIMETSU NO YAIBA (DEMON SLAYER) CHARACTERS OR PLOT.
