Moments before...
When Kozue entered his shopping mall, he immediately ordered the dimensional store to take him to his room in his homeworld(DxD).
During her escape since she noticed Borsalino, Kozue's mind thought at high speed about her next actions.
After considering his options, he knew he couldn't lure Borsalino into the mall and trap him.
If he did, he had to kill him to hide the secret that his mall could trap anyone who entered.
And whether he killed him or captured him for good, the Navy and the World Government would never leave him alone from that day forward.
He also considered modifying Borsalino's memory before releasing him, but that wouldn't matter either because the Navy and the World Government would still be targeting him.
It all comes down to the fact that he didn't have enough strength to fight the Navy and the World Government and they left him alone like the emperors of the sea.
Knowing that he needed strength, he knew that the only thing that could help him gain strength was the dimensional shop.
But there was a problem.
The Dimensional Shop only gave him points when a person bought a product from his shop, a task he couldn't accomplish if the Navy and the World Government were after his head.
It doesn't matter if they can't hurt you inside your mall.
Just wait outside and don't let anyone in, and Kozue won't be able to get any points from now on.
They could even launch a Buster Call on Arabasta if they realized they couldn't damage their mall.
That's why he couldn't catch Borsalino or kill him because Mariana wouldn't give up so easily if he did that.
Thinking about the future, he could only let go of the idea of catching Borsalino and resolutely escaped to his world.
"Where are we?"
The voice that asked was Mikita's, who had a chocolate bar in her hand.
Mikita was resting in her room eating chocolate when she suddenly appeared here lying on Kozue's bed.
Beside him, Robin sat with a calm face but also looked at him while waiting for his answer.
She was reading a book before appearing here.
Sigh*
Kozue sighed, and told them her story.
Of course, he didn't tell them he was reincarnated, just that he was a normal student who obtained a dimensional store that allowed him to travel to other worlds.
And now that an admiral was waiting for him outside, Kozue brought them to his world.
"In short, you won't be able to earn more points if you stay, as the Navy will surround the mall if they can't catch you."
"That's why you traveled here while in my world time remains frozen."
Robin analyzed what Kozue said and came to a conclusion.
While she appeared calm, she was inwardly shocked by the existence of other worlds.
"It's amazing! We can go to other worlds!"
Of course, Mikita was the most relaxed and found all this fun.
"Yes, that's why we'll stay in this world until I get enough points to buy more skills or I can go to other worlds" Kozue said.
"When will you be able to travel to another world?" Robin asked.
While she was already intrigued to explore the world she was in now, she was even more curious about the next world Kozue would be able to access.
"I don't know that yet."
"The dimensional store only told me that after making a certain number of sales, I'll be able to travel to another world," Kozue replied.
"For now I'll focus on using the dimensional shop in this world to get more points."
"I'll wait until I'm strong enough to return to your world or I can travel to another world."
"whichever comes first"
With that decided, Kozue took them out of her room and secretly took them out of her house.

The next few days passed and a week later Kozue opened a small shop.
Since he was a minor, the store was in Robin's name.
Using points in the dimensional shop, Kozue bought real identities in this world for Mikita and Robin, and put ownership of the shop in the latter's name.
Since Robin was her slave, the dimensional shop saw this shop as her property and she could sell goods here and receive points.
The reason it took a week is that I needed time for all the permits.
Unlike his shop in Alubarna, where with his strength and access to large amounts of water he could help the kingdom, here in his world he needed permission to open a business.
With the help of magic, that time was reduced to one week.
I could have done it in less time, but I needed to leave no clues for the supernatural world.
So if anyone investigates how he obtained the necessary permits so quickly, they will only find a case of corruption where some money was exchanged.
With the shop ready, he used his remaining points to purchase an underground training ground with gravity-boosting capabilities and spent his time training.
Robin and Mikita, for their part, took turns training and managing the store.
While the store didn't allow theft, someone had to be present to receive money from customers.
It was possible that some customers would not pay and the dimensional shop would catch them, causing Kozue to have to spend time correcting the problem.
Time passed and Kozue had to return to school.
While she could have not attended, she had to use mental magic to convince her parents and Kozue didn't want to do that.
Furthermore, he was already in the sights of the city's ruling demons.
Rías wasn't the only one watching him.
He also found Sona's nobility spying on him.
Of course, Kozue remained training all the time and to them it seemed like she didn't leave her house, when in fact she traveled to her training camp through the dimensional store.
Through his haki, he could sense that his bullies were frustrated by his isolated behavior.
If Kozue decided not to go to school, it was possible that they would still visit him at his home, where he lives with his parents and does not want them to go near him.
Speaking of her parents, Kozue was thinking of sending Robin and Mikita as bodyguards for them, but with how weak they are now they won't be able to do much to protect them.
That's why he had them train for now and bought several protective magic items for his parents from the dimensional store.
These magical items were strong enough to protect them from a high-class being.
As you earn more points, you will be able to purchase higher-capacity magic items.
One of these items allowed him to teleport them to his location.
If he couldn't bring them to him, he could also know where they were so he could go and rescue them himself if the need arose.
In short, he spent his entire summer training and strengthening Robin and Mikita.
For now he was strong enough to protect himself from the enemies he will have to face in the near future.
But Robin and Mikita don't, and that's why he'll buy skills for them.
Of course, the shop grew in the following months since it opened and was able to obtain the necessary points to buy observation haki and the 6 marine styles.
It will be after their bodies are strong enough that they will acquire the ability of Armor Haki.
They trained their Devil Fruit abilities on their own with the advice Kozue gave them.

Wearing his new uniform, Kosue headed to his new school.
Academia Kuoh
As a school that was previously attended entirely by women, this year's acceptance of boys caused quite a stir among teenagers.
Of course, the competition to get in was fierce, and Kosue had to accept that the so-called 'perverted trio' had to work hard to be among the few accepted.
'That's the power of a horny teenager,' Kozue thought with a laugh as she walked into the school.
Since it was the first day, Kosue wanted to keep a low profile.
Since he had purchased the knowledge to suppress his energies, he didn't think he would attract any more attention from the demons than he already had.
What he didn't expect was to meet Aika Kiryuu.
Aika Kiryuu was a seemingly normal young woman, if we don't take into account her strange ability to tell the size of a man's member just by looking at him.
And when he came face to face with Kozue, his eyes widened in surprise and he had a nosebleed like an old pervert.
Of course, his nosebleed caught the attention of the class and he had to go to the infirmary.
Kozue of course knew what really happened as he remembered this girl's strange ability, so he looked away while telling himself that what he did was what anyone in his position would have done.
