With the Summit of the Western Sky map in hand, Kahn quickly located Birka.
Because it was the next stop after Angel Island.
If not for Apayado being hurled up by the Knock Up Stream, Angel Island and Birka would simply be neighbors.
Perhaps because of that adjacency, after Enel destroyed Birka he chose Angel Island and occupied God's Island, Apayado, with its centuries of history.
"Let's go. We'll have some fun here for a few days, then visit other sky islands."
After buying the Summit of the Western Sky route map, Kahn was in no rush to depart and smiled at the four girls.
This world has luck and fate.
The Paramecia Lucky-Lucky Fruit and the Nika Fruit are prime examples.
If not for Kahn the transmigrator, the next host of the Logia Rumble-Rumble Fruit would certainly be Enel.
Enel is twenty this year.
Not too young, not too old.
He might already have eaten the Rumble-Rumble Fruit, or he might not have.
Kahn tended to believe Enel had not eaten the Rumble-Rumble Fruit.
A boy bullied from childhood for lacking wings who suddenly gains near-invincible power would first repay those bullies.
Twenty is an age when one's views are set and the body enters its prime.
But Enel destroyed Birka in Sea Circle Calendar 1514, eleven years from now.
With Enel's temperament, he wouldn't endure that long.
So at this point he likely hasn't eaten the Rumble-Rumble Fruit.
Thus Kahn decided to spend two days on Angel Island with Robin and the sisters, then use "going to see other sky islands" as the pretext to head for Birka.
After buying novel sky-island specialties, Kahn didn't carry them back with telekinesis. He had the shopkeepers deliver them to the Grantaine.
The residents of Angel Island wouldn't refuse a request from Blue Sea "tycoons."
Once the goods arrived, the Boa sisters immediately went to try the Wavers. It was their first time seeing such tiny "boats," and they were eager to figure out how to use them and how they felt.
Robin opened a parasol, sat on an outdoor sofa, and dove into the history of the sky islands.
Kahn, meanwhile, watched the sisters with innate Observation Haki while dismantling a Waver to study its internals.
He planned to visit God's Island, Apayado, tomorrow to find the extinct Jet Dial and mount it in the Waver.
Though Wind Dial and Jet Dial differ by a single word, their speeds are worlds apart.
A Waver with a Wind Dial can at most skim over water.
A Waver with a Jet Dial can even run on land.
The speed difference is like an electric scooter versus a motorcycle.
That is the speed Kahn wanted from a water scooter.
It has to be said: telekinesis is truly an all-purpose power.
Fused with innate Observation Haki, it is even more useful than Enel's mantra.
Enel's mantra only senses and eavesdrops; to attack within range he must turn his body into lightning and cast it out, with far too long a wind-up.
By contrast, Kahn's one-of-a-kind perception not only senses and reads hearts, it lets him control everything within range with telekinesis—including living people.
Though telekinesis can't directly attack the interior of a human body, it can bind a foe, then hurl nearby pebbles or branches as bullets or blades to kill targets from extreme range.
If one can't break Kahn's telekinetic restraints, anyone caught by it will struggle to escape death.
Beyond battle, telekinesis is a marvel in daily life as well.
For chores or fetching things, Kahn doesn't need to move—he just thinks and it's done.
So it was with the Waver.
With telekinetic help, he quickly disassembled it, let every part float in the air, located the Wind Dial, then reassembled it.
He took it apart again, removed the Wind Dial, and put the parts back.
Without a Wind Dial the Waver became a display piece.
Kahn dismantled it once more and reinstalled the Wind Dial he had taken out.
He twisted the throttle, found the Waver powered again, and nodded in satisfaction.
Then, wrapping himself in a telekinetic veil, he rode the Waver down to the sea to play.
Four Wavers circled the Grantaine.
The Boa sisters, unfamiliar with the controls, toppled into the sea many times.
But they quickly surfaced, and with Kahn's telekinetic aid kept riding—sometimes in a chase, sometimes just enjoying the sea breeze.
Robin, meanwhile, was immersed in her books.
When Kahn and the three returned aboard, Robin was still reading.
So Kahn, rarely, played butler, brewing her a pot of red tea and setting out some snacks.
At the sight, the Boa sisters felt a stab of guilt.
They were truly falling short.
As maids, beyond relying on Master and Robin, they could do almost nothing.
Among Kuja warriors, strength is beauty.
Not only the sisters but all Kuja train from childhood in swordplay, martial arts, archery, and Haki.
Every Kuja dreams of joining the Kuja Pirates and sailing with the Empress.
As for domestic skills, no one bothers to learn them; you'd be laughed at.
Now the sisters felt they should change.
Beyond raising their power, they needed to learn a maid's skills from Robin.
Having happened to read their hearts and notice this thought, Kahn couldn't help a silent laugh.
Just by playing butler once, he had made the Boa sisters resolve to change on their own.
