*first book* This is the modern au and my au, so tanjiro is the student and giyuu is the teacher Giyuu is deeply in love with tanjiro so he will kill anyone that is in his way or if they hurt him. Read to find out if giyuu is successful or not.

Tanjiro Was going to a party with a few friends. Then he meets a guy and starts randomly kissing on him. Because He was drunk. But, the man didn't seem to mind. In all honesty, I think he likes it.

Giyuu and Tanjiro have been dating for 8 months, though they have not told anyone besides •Nezuko •Shinobu •Uzui •Mitsuri •Kanao All though Shinobu and Mitsuri found out without being told. ☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎ Giyuu and Tanjiro always wait for one another to get off a mission. So when one day, Tanjiro completes a mission with Zenitsu and Inosuke, there's no reason for them to not be suspicious when Giyuu is always waiting for Tanjiro to get back. They feel like their is something going on between them so Zenitsu decides that they should start following them. They then start to follow them around to figure out why Giyuu and Tanjiro are so close and why they are always together. Sooner or later Giyuu and Tanjiro starts to feel like someone is watching them, but they don't pay any attention to it, though they feel like they should limit what they do just in case. ☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎☾︎•☽︎ What happens when they forget about the person watching them and they get a little bit to close to just be called friends..

Giyuu has always had the feeling of loneliness even with his new friends in the hashira, but when he meets Tanjiro the feeling just goes away. Eventually, a new feeling started to appear while around Tanjiro. After Giyuu and Tanjiro got close the redhead started to notice that Giyuu has had sleeping problems so he's set out to help the boy. Tanjiro has tried everything... Or at least he thought till one night... This is a Solemate AU wear you feel safer around your solemate than anyone and your solemate has a smell that you can only smell, they always release it but they might release more to calm you down plus many more reasons or they might stop the sent for a few minutes for lots of reasons but you can only stop the sent for 3 minutes you do have to at me smell your mate once a week since you find each other the less you smell them the weaker you get. Also you have to be older than 16 to meet your soulmate. In this AU The demon slayers travel with another slayer if the slayer Is their mate or they just travel with their mate so they don't run out of energy. In this AU Giyuu is 18 not 21 This might be a short Story depends on how many people read and like it plus on how bored I get with writing my other stories I also don't go slow like it sounds and I kinda have tanjiro find out about the problem of sleeping the first day he's there but other than that I'm trying to stick to the plot.

DISCONTINUED What would become of Water Hashira Giyu Tomioka had he become demon? If he had come just half a day earlier? Well, that we'll never know. But, what about later on? What should happen if he fell into the hands of darkness, sinking into the depths of evil? Could he possibly be brought back? Or perhaps he'll give in to bloodlust, and a solution be found far too late. Would Giyu Tomioka feast on human blood before a cure could reach him, or will a strange feeling only experienced once before prevent the horrid fate of slaughter? ••• First chapter or so may kinda suck, I'm bad at beginnings ->- latter chapters should be better! 2024: Y'all got this to #1 in giyuxtanjiro how the hell- ••• AU NOTES: 1. An AU where Tomioka Giyuu has been turned into a demon, and Tanjiro seeks out a way to cure him. Along the way, Giyuu seems to give off new emotions and grows closer to Tanjiro, possibly revealing something to the demon slayer as time goes on. 2. Everyone has been aged up to around four years for legal reasons. Those ages can be seen as follows: Tanjiro - 19 | Giyu - 25 | Zenitsu - 20 | Nezuko - 18 | Inosuke - 19 | Muichiro - 18 | Kanao - 20 | Genya - 20 | Aoi - 20(?) | Uzui - 27 | Rengoku - 24 | Mitsuri - 23 | Obanai - 25 | Sanemi - 25 | Gyomei - 31 | Shinobu - 22 3. Nezuko has already been cured and all of the pillars are alive. This won't match up with the manga, though I can't guarantee that I won't make some references to it.
