Giyuu lay dying on his 25th birthday recounting all the good times he spent with his friends before and after the final battle with the demon king and his servants. Yet, as he takes his last breaths and finally finds solace in the life he's lived, he is mysteriously transported back a whole 8 years in the past. Now faced with a second opportunity to correct his mistakes and save the lives of those he felt indebted to, what would he do? -Certain character ages may be changed for the sake of the story (specific birthdays will be explained later). -Manga spoilers (why would anyone read a fanfic about the end of the series if they didn't finish the story)

MODERN AU! (as requested~) #1 in giyushino (more than 3 times) #366 in Anime (out of 1k plus books! That's like what?! 36.6 %?!!!!) In a world of betrayal and obsession, love is the most dangerous weapon of all. To end a brutal gang war that has already claimed hundreds of lives, the leaders of the Butterfly Syndicate and the Water Fang Clan strike a single, desperate compromise: a marriage. Cold, silent Tomioka Giyu-Water Fang's most feared executioner-and the venom-tongued Shinobu Kocho-Butterfly's deadliest strategist-are forced to share a territory, a house, and a wedding band neither wants. If the truce fails, both families will burn. If they fail each other, the city will drown in blood. Shinobu sabotages every mission to spite the man who embodies everything she loathes. Giyu counters by exposing her carefully guarded vulnerabilities. Nights blur into tense arguments, thin walls, and unspoken longing neither of them dares acknowledge. Giyushino~ (might get dark...) None of the characters belong to me~

Hello everyone. This is my first ever fanfic, I have read many different giyushino fanfics and decided to create my own. If you have any feedback or ideas that would be greatly appreciated. This AU is set in modern time. There will be an explanation of characters and setting in the first chapter of the story. This story is about investigating crime scenes as well as drama outside and inside the work environment. Yes, this story mainly focuses on GiyuShino, However, I don't want to make a story solely focused on the 2. Id like to incorporate the other characters as well. I feel a good story should have multiple themes to it rather than just romance, such as; action, etc. If you're looking for just romance between the two then this story may not be for you. But, if you're looking for a story thats thrilling, but also incorporates other themes like romance, action and suspense then this may be what you're looking for. Other ships include: Sanekana Obamitsu And the usual canon ships Grammar is a big thing for me. A pet peeve of mine is improper grammar. I understand writing long stories are bound to have mistakes so I will try to keep things at a minimum but if you notice any errors feel free to correct me. If you have any ideas for filler chapters please comment them. If I use your idea or make a chapter based on inspiration of your idea I will credit you either in the beginning or in the end of the chapter. I do not own any characters of the demon slayer world.

Status: On-going P.S: this story seriously needs fixing lol, please bear with the grammatical errors and misspelled words, I will work on them when I have time - I literally meant when I'm in the mood.

{THIS IS MY FIRST STORY!! So its not as fancy decorated like others!!😭 but I will work on it as I make more chapters!!} and I deeply apologize if the characters do not act their canon personalities to me they are really unpredictable😓 This is also my own AU! So some things slightly might not be canon accurate!! ... As Giyu and Shinobu spent more time together, their connection deepened in unexpected ways. The initial awkwardness soon gave way to a comfortable camaraderie, allowing them to share quiet conversations beneath the stars, with smiles lingering just a bit longer than usual. Giyu admired Shinobu's vibrant spirit and her unwavering dedication to helping others, while she valued his calm demeanor and protective instincts. Their playful teasing became a familiar part of their interactions, filling the quiet corridors of the Demon Slayer Corps headquarters with laughter and warmth. Facing numerous challenges side by side, they built a strong sense of trust and intimacy. They found comfort in one another's presence, providing support through the struggles inherent in their roles as demon slayers. Gradually, what started as a friendship evolved into a deeper bond, as they both acknowledged the feelings that had quietly blossomed between them, drawing them ever closer as a couple. 💜
