Only Luffy, Robin, & Jinbe haven't made their requests. So they keep adventuring with pant-less Jon who wears speedo because of Franky's request. They stop near Marine Bases from time to time so Jon can steal treasures those marines looted from pirates they defeated.
Jinbe finally makes his request when they are in Fishman Island as they cross from the New World to Paradise. His request is to grow beautiful plants in the Fishman District that have been closed under King Neptune's order to give all Fishmen equal status.
But Jinbe grew there and wants it to be known as a beautiful place too. The Sun Pirates have tried to plant trees there, but they all failed. So Jinbe wants to try if Jon's jutsu can work there and Jon agrees immediately.
But before he uses his jutsu, they need to prepare a few things. First, they make a big bubble that covers the entire Fishman district. Then Jon uses his Mokuton jutsu to extend Sunlight Tree Eve's trunk to Fishman District so it will be a lot brighter and the light will also help the trees grow.
After that, Jon breaks down the ground as if he's plowing it and flips the soil around to make it easier for the plant roots to grow. They also add fertilizer which is organic trash from Fishman Island like leftovers from restaurants.
Jon finally uses his jutsu after all the preparations are done. To make sure the plants will grow, Jon decides to grow them from seeds instead of just creating plants out of nowhere with jutsu. He spreads seed of seafloor plants they bought in Fishman Island before using his jutsu to make them grow.
In a short time, the once dark and gloomy Fishman district becomes a beautiful garden. It can be another natural tourist attraction beside the Sea Forest. But they need to take care of it really well to make sure it stays beautiful.
After Jinbe, it's Robin's turn to ask something from Jon. She doesn't ask anything grand or strange. What she wants is just spending time together with Jon on Sabaody for a week. Basically, she asks for a date with the man she considers as a younger brother.
Among all members of Straw Hat Pirates, Jon is the one she spends the most time with. They were together in the Revolutionary Army during the 2 years training. Those 2 years were the time when they considered each other as brother and sister.
That's why Robin also thinks of Jane as her little sister because Jane is Jon's sister. She is very happy to have 2 little siblings she never had before. But now she's about to part ways with his little brother who is taking another step in life.
She feels lonely now that Jon is about to leave the crew. That's why she asks for a date because they won't see each other every day again after Jon leaves the crew. She wants to spend time with him and talk about a lot of things.
"My little brother is getting married before me, huh? Fufufu. You have grown up a lot. I still remember that one time you and Koala cried like babies because your tandem bicycle broke."
"Ugh! W-we were too drunk at that time."
Jon's face reddens as he remembers that shameful incident. He & Koala were very drunk and rode a tandem bicycle. But they crashed and broke it. Then they cried like babies when they thought that Dragon would be angry at them.
Robin then says some more of Jon's embarrassing moments when they were in the Revolutionary Army, making Jon very embarrassed. Good thing it's only the 2 of them or Jon will really die out of embarrassment.
Jane makes the next request after everyone tells her. She thought she couldn't make a request because she is Jon's sister. But the request is for everyone in the crew, which obviously includes her.
"Then, I want to sleep together with brother until we arrive in Alabasta."
By sleeping together, it really means to sleep next to each other. Jane is a system that becomes a human by Jon's request. She has always been with Jon since she was created and soon they will get separated.
At first she didn't really feel anything because she never experienced separation with Jon. But she starts feeling lonely when she imagines the time without him. So she asks to sleep together and gets very clingy to him until they arrive in Alabasta.
The crew finally arrived in Alabasta after days of leisure sailing. They really take their time and move at slow speed to stay just a bit longer with Jon. It's still hard for them to believe they will separate with one of their friends soon.
When they arrive in Alabasta, Luffy finally makes his request. He asks for an arm-wrestling, so they do it on a big boulder. They don't do it on their ship because it is a serious match and it can destroy their ship.
It isn't even an exaggeration because right when they start, the big boulder they use as the match table is cracking. Both of them are getting even more serious and exert more power. They even use their advanced haki too.
The big boulder gets destroyed when they start using their haki. A mere rock surely can't survive a clash of 2 best haki users that creates a big crater after the boulder is destroyed. Some phenomena are also created by the clash and force the Straw Hats to retreat quite far.
Black lightning strikes everywhere, pressure can be felt around them, cracks spread everywhere on the ground, slight tremors can be felt even from a fairly far distance, wind breezes in all directions which then becomes a big cyclone above them, and then the sky turns dark.
Everything happens because of 2 men having an arm-wrestling match. Well, they aren't ordinary people, but to create a crater the size of a town because of an arm-wrestling match is still something that's hard to believe if one doesn't see it themselves.
"Jon! Who's the strongest?"
"I am the strongest. Who's the best Captain, Luffy?"
"Obviously me. Who's the best ninja?"
"No shit! It's me! Who's the best pirate?"
"The Pirate King, me! Who's the best crew?"
They grin widely and answer at the same time.
""STRAW HAT PIRATES!""
*BOOM*
Both of them are exerting all their power which enhances the phenomena and increases the crater's size. Luffy is activating his Gear 5 and Jon is activating his Six-Path Mode. They are using so much power that the phenomena they caused are getting more dangerous.
*BOOM*
But then everything disappears in a blink of an eye as dust covers the whole crater so no one can see Jon & Luffy. That last booming sound was the sign that their match is over. But no one knows the winner yet because of the dust.
Franky clears the dust by blowing a lot of air from his mouth. Now everyone can see the result of the match which doesn't surprise any of them. Jon wins the arm-wrestling match because as he said, he is the strongest.
