*** Goa Kingdom ***
Oh the dock yard of the Foosha village of Goa kingdom, one can see a huge ship docked there. The ship has figurehead of red rising dragon, there are three main masts to this ship. And each mast has red strips on white sails. There is a huge skull drawn on the sails. The skull has its left covered in red strike, and two swords inter crossing each other on the back of it. At the peak of each mast there is a pirate flag flying with the same skull design as the mast.
In a bar in foosha village one hear a banquet going on with various people singing and dancing but not like any noble's party but a free man party. A man wearing black captains coat is sitting near the bar counter, laughing and enjoying as his crew mates sing and dance. A little kid wearing a yellow t shirt and black shorts is drinking juice beside him. The kid has long black hairs and chiseled face. One knows from one look at him that he will grow up to be a walking lady killer.
"Shanks I want to go to sea with you", the kid
"Not a chance Luffy. You can go to sea only after you are 18 years old", Shanks
"But I want to go now. I can swim faster than a fish and my punch is like a pistol", Luffy
"Ok Luffy we will see. Now hear have drink" Shanks said passing a glass of juice to Luffy
"Oh thanks shanks I love juice" Luffy replied innocently
As Luffy took the glass and started drinking the juice from it, Shanks started laugh loudly while saying "See still a kid." at Luffy
"That was dirty Shanks", Luffy shouted at him
Seeing what happened Shanks whole crew joined Shanks in making fun of Luffy.
Frustrated Luffy took the little chest that was kept on the counter. Took a weird looking fruit out from it and took a bite out of it. Tasting the worst and disgusting fruit Luffy tried to spit it out, but nothing came out. He threw rest of the fruit somewhere in hurry and took the half full glass of juice and started drinking it in huge gulp. It was then when a voice rang in luffy's head 'Ding Consumed Rumble Rumble no mi. First devil fruit power received. Received curse of sea. Host now vulnerable to water and sea stones. 10,000 System currency gained. Fruit on the top extremely desirable fruits list, system currency gain multiplied by 500%. Total of 5,000,000 system currency gained.'
Luffy was very familiar with this, as it rang in his head when he swam, run or played. It always gave system currency points but he dint know what was that anyway. One time when he was two he had called out system in his head when a transparent virtual Ai had popped up in front of his eyes. So he knew about the system and that the system could talk with him. Before he could contemplate what was going on with his system, he felt someone grab him by his legs shaking him up and down while shouting "Spit it out. Spit it out"
Luffy came back to his senses and said while looking at Shanks "Shanks that was the most disgusting tasting fruit he ever ate. I hate it. Give me something else to eat."
"You idiot, you just ate a devil fruit", Shanks
Luffy tilted his head in a cute manner and asked "Devil fruit?" One could even see a question mark floating on his head.
"Yes devil fruit. Now can never swim in water." Shanks replied
It took Luffy a minute to register it before he shouted "What? But I want to swim. Shanks help me, I want to be a pirate"
As Luffy said his full he was suddenly surrounded by electricity and he shocked Shanks, Lucky Roo and Ben who were standing close to him.
*** At night ***
Luffy had calmed down somewhat when Shanks had explained him what a devil fruit was. He had promised him that he was going to train him for next one year here on the Island, so that he can control his power and not accidentally shock someone. Makino and village chief totally agreed to have them stay.
Now Luffy was alone in his room at Makino's house as this is where he lived when his Grandpa was not around.
'System' Luffy called out in his head
The AI popped up in his vision. 'Hello Luffy, how can I help you?'
'Hello system, when I ate the fruit you said something about the curse of the sea and shanks also said something similar to it. What exactly is that?'
'Well Luffy, curse of the sea is a curse that you get when you eat a devil fruit. It makes you unable to swim in sea water, but you can take bath in fresh water. It also makes you loose power when come in contact with the sea stone. If you want to get rid of this curse, you will have to spend some system currency and train your body so that you can atleast fight a marine captain.'
'But system how do I spend the system currency? I dont know.'
'Just call out shop and you will be able to spend it'
'Ok. Shop'
As soon as Luffy called out shop, his view changed as he could see now 7 buttons flaoting instead of ususal AI. They were Weapons, Devil Fruits, Training Gear, Training Mannuals, Food and Clothes, Beli Counter and One Piece by Oda Sensei from left to right
'System what is One piece by Oda sensei?'
'One piece by Oda sensei, is how you had lived your life in another timeline. It is your story. You can click on it and can see what happens with you, as it might not be exactly the same as it will happen with you but it is quite similar. It will show you your complete life in the duration of 300 hours. When you are watching this, time on the outside world will move ten time slower than usual. I recommend you to watch this after Shanks has left.'
'Ok as you say. Now you said it was possible to remove the curse but where is it?'
'That option will appear on its own when you are strong enough.'
'Ok'
Luffy then clicked on weapons and checked out the weapons shown. The weapons were divided into two tabs. First was close combat and second was long range. There were many weapons that Luffy saw here, he knew some of them. And many that he dint knew about. He wanted to ask about them, but then thought lets first see what shanks is going to train him with then he can look for weapons.
In such manner Luffy clicked on each button to see what shows up. After checking them out, he went to sleep as he was tired from playing with Shanks and the gang.
(Authors Note : It is just info dump so lets skip others. And dont want to drag on Luffy's childhood for long so time skips will be fast so as to start with the plot.)
*** One year later : At the Foosha Village port ***
Luffy was standing with Shanks, while other guys loaded the supply.
"So I guess it is time to say good bye Luffy" Shanks
"Ok Shanks. But I am not going to ask you to take me with you." Luffy
"Oh why is that Luffy?" Shanks
"Because I will become the Pirate King and then come to look for you" Luffy replied with a big smile
"Oh so you are going to come after us." Shanks teased
"Ummmmmm..... " Luffy said nothing but had tears in his eyes as he dint know that he will have to go after them
Shanks and guys laughed out loud on seeing Luffy's expression. Shanks removed his hat and placed it on Luffy while saying "Then return this hat to me when you are strong enough. Okay"
Luffy nodded between his tears.
Shanks and his gang then left for the sea while waving at Luffy and others till they were far from sight.
Luffy returned with Makino to her bar, they had there dinner and then Luffy went to sleep early as he was missing Shanks
Next morning, Luffy woke up before dawn and went to the field to do his training, as he had done with Shanks for the past year. He started running, then squats, then controlling his powers to attack the target that Shanks had created for him to practice on. After training his powers, he took out his small training wooden sword and then started practicing which was taught to him by Shanks. After swords it was time for shooting which Yassopp had taught him. After completing his daily training he had lunch with Makino and then went to play outside.
Days went by like this for a month when a marine warship with a dog figurehead docked at Foosha village. Luffy did not yet had wanted to look at the One Piece videos, he had planned to do it after he was strong enough to remove the curse of the sea. He was sitting idly at his favorite spot, when suddenly he felt some danger from behind. He wanted to get up and run but before that a fist was smacked on his head and it went through him giving a shock to the attacker. The attacker quickly retrieved his fist, and attacked again but this time it did not pass through but hurt Luffy like hell.
"It has been a long time. Eh Luffy" the figure said to Luffy
"G.. G... Grandpa" Luffy called back between his tears
And so once again Luffy lived through hell with his grandpa for the next one month.
Just like the plot, Garp took him to Dadan family where he met with Ace. Then Luffy everyday followed Ace around to befriend him. One day when Luffy was following Ace, Luffy fall down a valley. When Luffy woke up, he was hungry so he bought some food from the system and started to watch One Piece from Oda sensei. By the time Luffy was done with food he was already at the point where he met Ace. There were some differences between his life and the one that he saw. He looked different from what he saw, and the devil fruit that he saw being eaten was different than the one that he had eaten, then he saw that Shanks dint stay with him for that long. But other things were nearly the same. After some time he drifted into sleep. Next morning he woke up did his exercises and started to climb out of the valley. After that the plot went the same, he chased after Ace and one day he finally caught upto him in gray terminal. He was caught by the bluejam pirates, when he used his powers to beat them in front of Ace. After that Sabo came, and the three befriended just like the plot. Luffy was caught up in playing with Ace and Sabo to have any time to see more videos again.
The plot continued the same, and then it was time for the celestial dragon to arrive here. Everything went the same, except that this time Luffy, Ace and Dadan all three came out of the Gray terminal with minimum injuries after defeating the Bluejam pirates. Few days later Luffy and Ace received Sabo's letter and then the news of Sabo's death. Ace and Luffy greived there eyes out.
It has been now one month after Sabo's death, Luffy and Ace have decided to leave the island when they are 17. Luffy then slowly started to watch the videos again. He saw everything untill Ace's death. That night Luffy cried again until Ace hugged him and then he slowly calmed down. By now Luffy was deeply involved with how his life had gone, so he started to watch the videos whenever he got time. He also started training hard, but wanting to know what happened entirely he dint stop. But the videos abruptly stop after he had reached coloseum in Dressrosa. When he asked system, why cant he see anymore then he got the reply that he can only see further ahead once he had reached to that time in his real timeline.
After knowing that Luffy focused on increasing his strength, as he now saw that strength was everything in this world. He asked system to schedule a plan for him to train. He also purchased training guides from system for Rokushoki training, Haki training, swordsmanship training, guns and aim training. He also taught Ace the Rokushoki training method and Haki training method. And so the time flew by.
Garp also visited them multiple times during this period and he noticed that how was his grandsons were maturing and getting stronger day by day.
