After learning that Kahn helped them improve their strength by using a Devil Fruit's ability to increase their biological age, Robin, Hancock, Mary, and Sonia were filled with anticipation for their eighteen-year-old selves.
Next, Kahn and his crew began their journey to find someone specific.
Capable of draining the blood Kaido has been sucking for twenty years without being drained dry, Wano is clearly a large island.
On this island, there are six cities: Kuri, Ringo, Hakumai, Udon, Kibi, and the capital of Wano—the Flower Capital.
These six major cities have many small towns and villages in their regions.
If you don't know the appearance and information of the person you're looking for, but only know they exist somewhere in Wano, it would take a lot of time to find them, even for Kahn and Hancock, who have unique perceptions.
Fortunately, Kahn is a time traveler and knows Shinobu's current location.
The death of Kozuki Oden and the time when Momonosuke traveled through happened last year.
When Kozuki Oden led the Akazaya Nine to defeat Kaido, Shinobu also joined the battle.
But in the end, after Kozuki Oden and the Akazaya Nine were defeated, because Kozuki Oden pretended not to know Shinobu, Shinobu escaped and wasn't imprisoned.
After Kozuki Oden's death, Shinobu and the Akazaya Nine fled to the Kuri region together.
Kuri is the stronghold of the Kozuki family, and Oden Castle is in this area.
Tama, who ate the Paramecia-type Kibi Kibi no Mi two years after the original story, lives in Amigasa Village, which is also in the Kuri region.
Therefore, Kahn doesn't need to go to the other five regions, but only needs to search through the Kuri region to find Shinobu, who is hiding somewhere.
As for where the Kuri region is, Kahn didn't know.
However, this problem is not difficult for Kahn, who has natural Observation Haki.
Bringing Robin, Hancock, Mary, and Sonia to a crowded town, Kahn just pretended to accidentally bump into a pedestrian, controlling the force precisely to knock the pedestrian to the ground.
Then Kahn supported this person in time, and his natural Observation Haki instantly read the other person's memory, soon learning the location of the Kuri region.
What surprised Kahn even more is that their current location was actually in the Kuri region of Wano, in a small town called Bakura Town.
Since Kahn was accompanied by four delicate and lovely girls, and his demeanor was like that of a nobleman, the pedestrian who was almost knocked down didn't dare to get angry at all and left in a hurry.
Robin, Hancock, Mary, and Sonia saw the entire scene.
As a qualified maid, Robin felt puzzled but didn't ask.
The same went for Hancock and Sonia, who had gradually become qualified maids.
Only Mary, who is nine years old this year and has a lively personality, asked, "Master, was there something special about that person?"
As if he had expected Mary to ask this question, Kahn tossed the money bag he had taken to Mary. While walking towards the hotel in the small town, he said in a low voice, "Wano is a country that has been closed to the outside world for hundreds of years. They don't accept outsiders and haven't joined the World Government, making it no different from Skypiea at an altitude of 10,000 meters."
"The currency here is also different from berries used in the outside world."
"I see."
Hearing the last sentence, the four girls suddenly understood.
Mary, who was about to open the purse, glanced at the pedestrians around her and immediately put the purse into her pocket.
On the way, Kahn also explained the currency of Wano to Robin, Hancock, Mary, and Sonia.
Like Sky Island's extols, Wano's currency isn't berries but platinum, Gold and silver.
Among them, platinum is the most valuable, then gold, and finally silver.
In the later Sea Circle Calendar 1522, after being exploited by Kaido for twenty years, Wanokuni had become very poor.
A platinum coin could build a house.
And five silver coins, while not enough to sustain a family for a week, could last for a few days.
However, in this period, platinum, gold, and silver are obviously more valuable than in later generations.
When Kahn and his group arrived at the hotel, they couldn't afford a suite and had to settle for one room, costing ten silver per day.
Had it not been for the passer-by's purse, Kahn and his crew would have had to pay in gold.
Since they hadn't brought smaller denominations, the smallest piece of gold Mary had was a gold brick.
If taken out, it would definitely cause a lot of commotion and could affect their subsequent actions.
After securing temporary shelter, Kahn began searching for Shinobu in the Kuri region.
Knowing their location, just outside Bakura Town in the Kuri area, Kahn released his natural Observation Haki to its fullest extent, his perception instantly enveloping the entire Kuri.
Immediately, Kahn began to select the strongest auras from the multitude.
More than an hour later, Kahn, who was sitting on the tatami in the hotel room, opened his red eyes and smiled slightly: "...I found her!"
When Kozuki Oden and Kozuki died, the Akazaya Nine had four members accompany Momonosuke across time.
The remaining Akazaya Nine are scattered in other areas of Wanokuni.
As someone whose strength ranks just below the Akazaya Nine, Shinobu's aura was as vivid as a firefly in the night within the Kuri area.
If it hadn't been for this area being filled with many swordsmen who understand Haki, Kahn would have found Shinobu immediately upon opening his perception.
Even so, it took Kahn just over an hour to find Shinobu among the strongest auras.
Currently, Shinobu isn't the 49-year-old short, fat, and ugly woman from later years, but a 30-year-old, slender and attractive lady in a ninja costume.
For someone who appreciates beauty, Kahn couldn't forget her at just one glance.
His natural Observation Haki also functions as a beauty sensor.
After finding Shinobu, Kahn immediately got up and took Robin, Hancock, Mary, and Sonia out of the hotel, heading towards Shinobu's hiding place.
Having been separated from her companions for less than a year and still in a state of confusion, Shinobu, who was waiting for her companions to return, chose to live in seclusion in the bamboo forest not far from the burned Oden Castle.
She now lives alone in that bamboo forest.
Before realizing that she couldn't wait in vain and needed to take action, Shinobu wouldn't leave that bamboo forest for a long time.
Such a remote location makes Kahn's next actions very convenient.
