William POV:
After four years a lot of things change.
First, the future will not be the same, as Fisher and I saved the slaves two years before the One Piece trilogy, there were no more problems, Fisher was able to recover the ships a year after they left, and he started his adventure with the sun pirate, as Koala followed me, Fisher no longer had to look for his native island, which allowed him to live.
Arlong has become friendlier to humans, although he is still suspicious of them, he still has good human friends, so he stayed with the Sun pirates, which allowed Belle-Mère to live and at the same time let Nami and Nojiko grow up with a mom.
Koala, meanwhile, she erased the ideas of being a slave, she had gone through three stages, the shy girl step, the energetic girl step, and the serene girl step, she has now sixteen years and with my training, she is strong enough that she can escape an admiral.
The biggest change was that now the fishmen have the same rank as the humans, all thanks to the ideas and perseverance's of Otohime and Fisher, and even if there is always sales of sirens, they are no longer common, and most by time we find these sales in black markets.
Otohime death is also saved, as Hody no longer has hatred towards humans or fishmen, he even entered the crew of sun pirates, and as he is a big fan of Arlong, he became under the tutelage of the latter.
Present time in Ryugu Palace:
Hmm, so you're leaving, jamon. Said Neptune.
Yes it's time to travel and see the world. Answered William.
Neptune: Hoh Hoh Hoh, if you'll see Edward, say hello from me.
William: Yes, beside take care of yourself, where are Otohime and the children?
Neptune: They are on the surface, jamon.
William: So tell them I'm gone, otherwise I think you have my Den Den mushi, so if you have any problems just call me.
Neptune, Okay, good trip William.
William: thank you Neptune, we'll see you one day.
After talking with Neptune, I went to see Koala, she must be ready for this long adventure.
Upon entering the house, I saw a teenager preparing the luggage, she is dressed with a little red skirt, a long-sleeved purple top with black buttons, and her hair is cut quite short.
Ok Koala you are ready for the trip.
Ehem, she replied.
Ok then let's go.
We go to a place where the ships are stationed, among all these ships, one that distinguish, it was big enough, and it looks like the ship corvette, but ten times bigger.
I bought the ship, by the system, it had the best technology, while resembling, to the boats of this era, it had dark black color wood, its sails are navy blue, with a large golden Kun Peng engraved on them, I did not want to be a pirate, a navy, a revolutionary... I wanted to create the emblem of my family, and venture into this world.
And the emblem that I chose, is a navy blue flag with a golden Kun Peng, some will say that I want to create a kingdom, but it's not my goal, my goal is to tell the world that I belong to no camp.
Then we boarded the ship, Koala was sailing, I stayed in a big chair, after a day we went to the surface.
I talked about other people, but I did not talk about my condition, the first thing is that I let my hair grow close to my shoulders, I was tall enough compared to children that have the same age us me, I was 1.60 meter (5.2 feet), for my strength, I can now fight an emperor, so now all that remains to me is to go to travel and discover my origins.
Go to the new world.
