Chapter 1

Were Luffy the man who'll become

King of the pirates and Cain the man who will become

Emperor of the sea

A pirate ship in the east blue (16 years ago)

We start our story on a pirate ship called Saint Maries fire, ship of the amazon pirates an all-female pirate crew lead by Lilith D. Arashikage and Monkey D. Luna the crew consisted of all women the sniper a woman named Banchina, a swords woman who went by the name Roronoa Zora, a spy in the marines named Bellemere, the cook Sani these were known as the first members when the amazon pirates were still a young rookie crew, the only male on the ship was a young boy named Cain D. Arashikage the son of the captain.

The crew was now taking time off they took Banchina back to Gekko island to see her son and husband Usopp and yasopp, they took Bellemere and the three girls she had adopted Kyma, Nami, and Nojiko back to the conomi islands, after that the ship was attacked by the black cat pirates Lilith and her daughter Pandora and her apprentice's Boa and Basilisk Hancock grabbed Cain and drifted in a boat till they were found by Don Krieg, Lilith fought but despite her strength since she was exhausted from the grand line, was captured but her kids escaped Boa and Basilisk were separated from their teachers kids.

who were soon found by the vice-captain of the red hair pirates Kazuma the wind sage, Kazuma took them in and for six years the red hair pirates helped to raise them, when Cain was three Pandora fed him the Copy Copy fruit a devil fruit that could copy other devil fruit abilities Pandora knew that her baby brother had the potential to use the fruit to its full potential meaning he could copy all the devil fruit powers without losing any abilities.

After that the red hair pirates went to a little town called fuschia village where Pandora met an old member of her mother's crew Makino while on the little island she met a boy named Portgas Gol D. Ace the son of her parents old rivals on the sea Gol D. Roger and Portgas D. Rouge, she and Ace hung out often and quickly became best friends she also met Ace's honorary brother Sabo and a girl named Artemis.

Soon she felt guilty for ignoring her brother contrary to what he thinks she knows that he remembers how they were separated from their mother being born a genius with a photographic memory and a prodigy and she saw him slip more into loneliness she eventually decided to introduce Artemis to her brother Artemis immediately liked Cain and claimed him as her younger adopted brother soon after though Cain met a boy named Monkey D. Luffy the son of their mothers vice-captain Monkey D. Luna, and their father's partner in the revolution Monkey D. Dragon while Artemis and Pandora were with Ace and Sabo Luffy and Cain could be found with the red hair pirates.

Luffy was trying to convince Shanks the captain to take him on a voyage with them he had even stabbed himself under his eye to prove he was tough now the pirates were laughing at him and Cain was calling him dumb while having a slight smile on his usually indifferent face.

"That was really a dumb move of you Luffy" said Cain to his friend.

Even though they were friends it didn't stop him from poking fun at his friend "now calm down Luffy and have some juice" said Shanks "no Luffy it's a trick" said Cain to save his friend from more humiliation and teasing from Shanks the crew kept teasing Luffy when mountain bandits came in demanding the alcohol which the pirates had drink the last of "sorry but there is one bottle left it's all yours" said Shanks the bandit leader broke the bottle spilling the drink on the floor and after further humiliation to Shanks.

Luffy angry with shanks ate the fruit in the box which turned out to be a devil fruit and Cain being near him absorbed his first devil fruit ability and had now officially become a copy man Luffy got chewed out by Shanks but they were soon friends again. The next day Luffy and Cain were spending time with Makino as Dora and Artemis were with Ace and Sabo the bandits came back that day and Makino was forced to serve them food and drink when the leader started flirting with Makino Luffy got angry and tried to fight the bandits.

But they took him out for a beating Cain tried to save him but also got a beating they were saved by the red hairs but the leader took them out into the water and were thrown into ocean to drown then a sea king came and attacked them but shanks and Kazuma appeared to save them and scared the sea king away with their conquerors haki but lost their arms in the process shanks and Kazuma stayed for a few more weeks and in that time taught Luffy and Cain the basics of haki.

After the red hair pirates left Pandora and Cain met their grandfather Constantine D. Arashikage who wanted them to be marines he took Cain with him Luffy and Luffy's grandfather Garp and left them to survive in the jungle on their own for six months what Constantine didn't know was Cain had nabbed his book on the six powers so he and Luffy could learn to use them.

They started with Kami-e which took a while but they learned then they learned moon step which would save them from drowning in the sea since they were basically flying, then came rankyaku, then shigan, then shave, and finally tekkai Cain continued to train with six powers in order to learn the seventh power the Rokuougan the ultimate power from the six powers, the two continued their haki training and to control their devil fruit ability.

When Garp and Constantine brought them back they were surprised Luffy was sent to live with a mountain bandit named Dadan who was also raising Ace, Cain and Dora could stay with Makino. Luffy decided when he was with Shanks he wanted to be a pirate and have Cain on his crew and Cain agreed to be his Vice captain and advisor on the ship.

10 years later

17 year old Cain D. Arashikage woke up in his bed and went down to the bar his guardian ran he passed near his older sisters empty room Cain didn't deny that he missed his older sisters, Artemis died because of the world nobles along with Luffy's older adopted brother Sabo and, Ace and Pandora left for their pirate journey four years ago Cain went downstairs to wait for Luffy to arrive over the years Luffy was still an idiot but the two had grown proficient with haki, six powers, and the gum-gum fruit power Cain hasn't learned the seventh power yet but he felt he was close as Cain sat there he ate his breakfast then Luffy came in and ordered some meat.

They finished eating and went to their boat they said goodbye to Makino and set sail to find the rest of their crew. The two man crew was sailing for a few hours when they got sucked into a whirlpool so they got into two barrels and floated away and came beside a passenger ship they were pulled on the ship and then as the sailors were about to open the barrel pirates started to attack the ship and the sailors dropped the barrels that had Cain and Luffy in it. The two barrels rolled down to the kitchen where they sat waiting till a young boy named Coby found them he started to roll the barrel up towards the deck of the ship when members of the crew he was on came in.

"Hey you tryin to hide from the action Coby" said the heavy set one "no I was just rolling this barrel of beer up for you guys and I think there's another one over there" he said the heavy set one set the barrels right and was ready to bust them open when two boys came out of them one of them shouting.

"I slept great" said Monkey D. Luffy "shut up captain dumbass" said Cain D. Arashikage, "hey your friends gonna catch a cold down there" said Luffy, "Luffy I think you're the one who put him there" said Cain oh said Luffy "well I'm hungry you guys got any food" asked Luffy, Cain sighed "that might be a pantry " Cain said pointing to a door "oh ok" said Luffy as he made his way to the pantry.

Cain followed him the kid who found their barrels followed them "who are you two and why were you two in those barrels" Coby asked "I'm Monkey D. Luffy" said Luffy and "I'm Cain D. Arashikage, and well our boat sank in a whirlpool so we got in the barrels to avoid drowning" said Cain. "What's your name kid" asked Cain "m-m-my name's Coby" said the boy "well Coby is this a pirate ship" asked Luffy "no its a passenger ship being attacked by the Alvida pirates" said Coby.

"So whose side are you on" asked Luffy "I'm forced to be with the pirates" said Coby "well this kid is weak" said Cain "I think your right Cain" said Luffy, "Luffy, Cain do you two have dreams" asked Coby "yep I'm gonna be king of the pirates" said Luffy and "I'm gonna be Emperor of the sea but my main focus is helping Luffy becoming king of the pirates" said Cain.

"Then that means you two are looking for one piece and conquer most of the territory of the grand line how do you hope to do that" asked Coby "because kid" said Cain "I ate the most powerful of all devil fruits the Copy-Copy fruit when I was three years old" said Cain.

"No, no, it's impossible those dreams are just completely impossible" said Coby till Luffy hit him on the head "why'd you do that" asked Coby "because I felt like it" said Luffy "guess I should get used to it" said Coby "That's how these guys always treat me Luffy, Cain if I devote myself to it do you think I could become a marine" asked Coby "how should we know" said Cain "it's your life and you have to live it your way" said Luffy as they got up after eating more apples "well time to find another boat" said Luffy "alright I've decided I'm going to become a marine and arrest Alvita" said Coby.

That's when the ceiling broke open and a very fat whale of a woman fell through it "who was that you're going to arrest Coby" asked Alvita "uhmm uh" said Coby "hey Coby who's the whale" asked Luffy "what was that you brat you don't look like pirate hunter Zoro, Coby who is the most beautiful women on the seas" asked Alvida "that's easy Basilisk, and Boa Hancock" said Cain.

"That's wrong brat" said Alvida as she through her mace down to hit the two young pirates but they dodged easy, Luffy grabbed Coby and the two jumped out of the hole Alvida made.

As soon as they got up on the deck they were charged by the other pirates, the duo started to fight them off Alvida came back up and hit the two pirates on the head with her Iron Mace "that thing is dole" said Luffy "I know right" said Cain "you two ate a devil fruit didn't you" asked Alvida "yeah I ate the gum gum one" said Luffy "I ate the Copy Copy one" said Cain the two then stretched their arms back and punched Alvida off the boat.

"You guys get Coby a boat he's joining the Marines" said Luffy "yes sir" said the pirates the marines arrived and started blasting the ship with cannons "look Coby the marines why don't you go join them" said Luffy "no I can't they might think I'm a pirate said Coby, "guys I got us a boat let's go" said Cain the trio left and On their way out Cain and Luffy made eye contact with two cute red heads and they set sail.

the trio sailed away from the cruise line and started making their way to an island with a marine base "so Coby tell us more about this pirate hunter Roronoa Zoro" said Luffy "why" asked Coby "if I had to guess Luffy wants him to join our lofty crew" said Cain "but thats a bad idea that man is a beast in human form a demon with blade" ranted Coby "if he's a good guy I'll let him join my crew" said Luffy "he's in prison of course he isn't a good person" said Coby "Coby I want you to listen very closely, not all pirates are bad, and not all marines are good there some good pirates like the yonkou red hair Shanks, and then their are marines that are corrupted by power or money" Cain explained as the three young adventurers set out for the naval base holding Zoro.
