Happy late New Year's!!

AU:
Giyu (M!Y/n) grew up on a sacred island. The island was hidden from the world and only few knew where it was. That island held demons and the people living there were called demon slayers. To keep the demons from leaving wisteria was placed around the island and the island was cut out from the world. It was the only way to keep the outside people safe. The demon slayers were taught sword styles and soon created breathing styles. Luffy's crew ended up finding the island and exploring it. Even though the island was very dangerous the people there accepted people from the outside world and treated them kindly. The only thing they asked for in return was killing a demon (like a bounty kinda thing). But Luffy, Nami, and Zoro soon realized that the demons regenerated and couldn't be killed. That's when Giyu saved them by cutting the demons head off. Ofc luffy and crew was mad he killed the demon so Zoro(sanemi if you watched the video to a certain point) fought him. Only after their swords broke (the wood swords in the videos) did Giyu finally get the chance to explain why their island kills demons. They ended up spending a few days there and Giyu ended up coming along (make up something I'm too tired to). Giyu (MY/n) was in his later 20s before they reached Ussops hometown. During the time on the ship to Ussop Giyu went through some drastic changes (which later ends up making him look like Captinio from Genshin, watch the first video to understand).
And bam! There is the crappy AU I ended up with. It's pretty sloppy because I'm tired and sick. So feel free to make a better AU that goes with the video or fill in holes as the video goes on.

So kinda like the "backstory" for Giyu/Captinio. Giyu is past M!Y/N and Captinio is future M!Y/N. Mitsuri is past F!Y/N and Shinobu is future F!Y/N. After the whole " angry at Giyu(male y/n) for killing that person who is a demon" concluded they met Mitsuri (female y/n) as Giyu and her are close (think about those GiyuMitsu friendship/sibling reaction videos). Giyu (male y/n) and Mitsuri (female y/n) both joined the straw hats at the same time. They both went through drastic changes (Giyu to Captinio and Mitsuri to
Shinobu). They were also distant with the rest of the crew for a bit but soon became closer to them. It was hard for M! and F! Y/N to cope with the changes from their world to the great big sea they now traveled on. Often M! and F! Y/N would try to kill their opponents as they were taught back home but the crew always stopped them. Even though M!Y/N quickly learned to not kill every enemy, F!Y/N never learned it. The crew would catch her at times trying to kill the enemy but she often played it off as a joke to scare the enemy (hints to the scene with her and the spider demon when I mean scare enemy). M! and F! Y/N never opened up about their problems or troubles but loved when the crew opened up to them. They all relatively get along.

Hope this AU makes sense. Kinda made it up on the go. Just a silly little thing to go along with the video ✨
