i hate to break it to the author but kinto-un as an oc and the story itself has been replicated at least three times. almost down to the exact wording.
coby clutched his bandana impossibly tight, the sound of cloth tearing loosening his grip, so the boy settled for twisting it between his fingers. he was back on his home island, before he climbed on that 'fishing' boat and even further before the crowning of the second king.
no one knew what had become of that man, the strongest bearer of the Will of D and the inheritor of that fated strawhat. when the last of his crew had been confirmed dead, and coby remembered the grief that rippled across the world, the man disappeared.
no one had seen him, for thirty years coby had looked high and low, scouring the deepest seas and as a last resort, the island of raftel. all that laid there was an intricate grave surrounded by memorabilia of every strawhat and a spotted hat upon a nodachi. there was no sign of the man or his precious strawhat.
coby fought his way through the trees, avoiding creeping vines and listening to the soft whispers that followed.
'you must be the young man that luffy inspired,' a voice greeted him when coby entered the clearing.
coby whipped his body around in the direction the voice came from, his eyes landing on the tall grave and a man that died nearly a century ago.
'gol d. roger,' he eyed the nearly perfect coat the man wore and the markings that ran along the man's throat.
thats right. they had cut the pirate kings head off like it was a prize to show the world, coby thought to himself.
'you're staring as if you've seen a ghost,' roger laughed at his own joke, the trees rustling as if they too found it funny.
roger waved the man over, 'sit sit and ill tell you what you want to know. you didn't bring any booze with you, did you?'
coby shook his head and sat next to the transparent man.
roger deflated, 'ah well, no harm no foul.'
and when coby had heard the story, he asked the man a favor. the man agreed, as long as when they met back up in raftel, he brought the best booze.
then coby woke up and he was waiting for the storm to come. this time it would be different.
coby being one of the few that remember is gold.
