ot8, pirate fantasy au, loosely inspired by my favorite character from one piece, you don't need to have read or watched it to understand because it's an headcanon of mine almost completely out of canon the only information you need to know is that piracy in one piece has lasted for over 800 years, auction mentioned, whump

chn is a human who can transform into a phoenix, his flames have healing properties, when he comes back from the ashes he still has important memories, in his first lives he doesn't know how well it works so always it's trial and error until he manages to use his powers to heal, to fight and to know how to fly, as time passes, people who know about his cure always end up breaking his trust, until in one of his lives he ends up at an auction, by pure coincidence 7 very unlucky pirates came into conflict with another group of pirates and almost destroyed the entire place, when the conflict ended one of the ot7 was seriously injured so chn saw an opportunity to bargain for a cure if they released him from the handcuffs, when they saw him using the flames they began to ask chn to be their crew's doctor but chn denies and continues on his way, after that begins a chain of meetings on different islands, at each moment they gain chn's trust little by little while at the same time chn is almost always getting them out of trouble until finally chn gives in because he can't stand to see these boys always getting hurt with a smile on their face so as not to worry him, so if they are going to get hurt let it be under his supervision, over time he started to love them.
In one of his past lives he wandered through places with libraries to learn more about the world and maybe find more about his species and in one of the books it said that his blood has properties to bind souls but it was just a book of legends, now that he had 7 men who would do anything for him and love him, he wants to try, after they accept and drink a few drops of his blood they feel as if they are connected by a string stuck in their hearts but it is comforting and warming like the flames of chn when he heals and when they are far from each other they feel the direction where each one is, like a compass that only points in one direction, after this life when chn is reborn another chain of encounters begins with the people he loves, they can remember a few little things here and there, they always end up forming a pirate crew, sometimes they just settle in a big house in the countryside on some island, sometimes they just go adventuring, sometimes chn is captured or imprisoned by the government because whether they like it or not their value is becoming known until they show what they are capable of if they touch a hair of his and every time they meet they fall in love.

sorry if it's long, i made changes to fit the idea of ​​my headcanon and ot8 love each other too much to stay alone in the found family
