Sin and Ash were both walking inside one of the ships.

"They took all the documents and important stuff from this one too," said Ash, this was the third ship they searched, but they didn't find anything important except a total of 40 million berries.

"Let's check the dungeon," said Sin.

"Thank you so much man!" cried a prisoner in joy.

"Did you really beat an admiral?" asked a blue-haired woman.

"We forced him to retreat" Said Sin with a smile.

"Do you mind if I join your crew?" she asked after a great deal of hesitation.

"And why should I accept you?" said Sin, amused and also interested.

"Because I'm going to be the world strongest swordswoman," she said with her eyes gleaming with determination.

"What's your name?" asked Sin, he had a feeling that this woman is special.

"My name is... Kuina" she said.

"They forced you to retreat!!!"Sengoku's loud voice came from the Den den mochi.

"We were in the sea, and I was escorting artifacts to the holy land, I couldn't go all out," said Kizaru.

"We need to change the bounty again," said Sengoku.

And like that the duo's bounty was doubled.

"...After that, I faked my death and came to the grand line and was caught by the marine who believed that I was one of the pirates" said the blue-haired Kuina.

'This is the girl that managed to defeat Roronoa Zoro 2000 times!' Sin was listening, but inside he was shocked.

"I believe you," said Sin.

"Huh" Kuina

"I believe you are going to become the world's strongest swordswoman, I also believe that one day you will beat even Dracula Mihawk," said Sin seriously.

"Eh, but I'm a woman..." she said with sadness.

"That's just an excuse, it's not about physical strength or about gender, it about your will, if you gave up halfway or if compare yourself to others, you will never succeed," said Sin.

*Sob**Sob*

Sin opened his arms and gave Kuina a hug.

"2986*Swosh*...2999*Swosh* 3000*Swosh*" Kuina was swinging a giant tree.

"We are going to train haki after that," said Sin.

"Hm" nodded Kuina.

"Ash!!" yelled Sin.

"Yes, young master," said Ash as jumped from the dark cloud.

"How are you observation haki?" asked Sin.

"Am close to breaking through to the 2nd level" he said.

"I need you to teach Kuina how to train her observation haki while I teach her the armament," said Sin.

"By the way why do you always keep calling Sin Young master, is he a noble, or even a prince?" asked Kuina while stealing glances at Sin from time to time.

Ash hesitate before Sin gave an 'It's okay' look since he didn't want to lie to Kuina.

"My young master... is a Celestial dragon" After seeing that Sin didn't have a problem with revealing his origin, he said.

"What!?" Kuina looked shocked, but couldn't believe it, but after seeing Ash's serious face and Sin's calm face, she could only accept it.
