great story but please don't make a harem, it destroys the story and makes it boring to see him go after a woman, it would be perfect if he didn't even have a woman, you decide ...
Wait a minute what? He said there was no trace of Shiki’s will so how would he be able to use Conqueror’s Haki? That’s nonsense, he’s got the weak willpower of a nobody.
Thank you for the prologue !!! The start is great to continue like this !! That he is a floating island like ship, that he saves part of the inhabitants of Ohara (without anyone knowing) while protecting Robin and Ace's mother to give birth normally all by giving Ace to Garp. That he recruits Boa Hancock and Perona (saving them and making them fall in love), Enel before he eats his fruit, kuina. For his age he is looking for Myskina Acier, the scientist who created "pure gold" so as not to grow old or grow younger since he is still young. Thank you I made you by just some ideas.
