Natsuki D. Subaru: Pirate In Another World.

Prologue

400 years ago, before the great calamity and the sealing of Satella, a man came to the Kingdom of Lugunica, by some unknown means. He claimed that he wasn't from the area and that he was something called a pirate, as well as being from the great waterfall.

He was a complete mystery, and he was strong enough to the point that he could handle the Seven Witches Of Sin as well as fighting the Sword Saint on equal grounds and actually defeating him. To the people, he was a hero, a kind man that would help anyone despite him being a pirate, an outlaw. But to the government, he was a threat due to how powerful he was, they wanted him to be under their control, they were afraid of him because of his mysterious powers and feared that if he really wanted to, he could put the kingdom into disarray.

When he found out about how they were planning to hunt him down, he decided to leave so that the people involved with him wouldn't be hunted and possibly executed. But before he left he said that he left some belongings of his across different parts of the world and took one book with him, claiming that one day, someone of his bloodline of the next generation would find them. After that, he left and never came back.

This man later on became a legend, as people would tell stories about the pirate and how he came from and made it across the great waterfall and lived to tell the tale, something no one has ever accomplished before, something that everyone thought was impossible. His name was...

400 years later

In the Land of Wano, the region of Kuri, in Okobore Town, we can a see 7-year old boy named Natsuki D. Subaru along with his mother Natsuki Naoko waiting for the arrival of Natsuki D. Kenichi, the father of Subaru and the husband of Naoko as well as a powerful pirate. You see today was Subaru's 7th birthday and the little boy was excited, he couldn't wait to see what gifts his father brought with him from the outside world.

"Mooooom, when is dad gonna get here?! I can't wait any longer!" complained the already excited Subaru.

Naoko looked at her son with a loving and caring smile as she replied. "I'm sure your father will be here Subaru, you know the rules that the country follows don't you?"

"Yeah..." said Subaru as he looked down as he remembered what his mother told him about the country's policy.

You see, Wano follows a strict policy of isolationism, meaning that contact with outsiders such as pirates and other countries is prohibited. Leaving the country's borders is also considered a crime and outsiders who enter the country are immediately attack on sight.

This policy was maintained as a result of the country's geography that makes an invasion very difficult, as well as it's powerful samurai warriors. But luckily, whenever Kenichi would come back after his voyages, it would always take him a awhile to make it back to Okobore Town because according to him, it wouldn't be fun without any action, so he would fight his attackers before seemingly disappearing into thin air, quickly getting out of that area.

And due to the poor environment of the town, Kenichi would go to the other regions and steal food from the wealthy people that didn't give a damn about the others who were poor but themselves, as well as stealing some money and bringing it back to the town, so that way them and his family wouldn't starve, and whenever food or money was stolen, he would already be gone without a trace, so they never knew who was stealing the food or money. To the town's residents and Subaru, Kenichi was the greatest, he was a hero in their eyes, and Subaru wanted to be just like him when he got older.

Right when Subaru was done reminiscing about the past, he heard a familiar voice, which caused him and Naoko to look towards it's direction, in the center of the town stood a man with a white buttoned up T-shirt, and an extremely long, black cape behind him.
