I don't own One Piece but I do own the plot of this story.
A young raven haired boy stood in front of an old man. "What are you talking about grandpa?" The old marine hero sighed. "Sengoku has found out about all three of you Luffy. He made a decision you either come and join the marines or they are going to execute you, Sabo, and Ace."
Luffy looked down at his shoe's silently. "Gramps if I do this Ace and Sabo will be safe right?" Garp, Luffy's grandpa, sighed nodding. "Sengoku will not go back on his word both Ace and Sabo will be safe until they do something to catch the marine's attention."
The raven took his precious straw hat off looking at it fondly. "Alright I'll go, but gramps can we drop my hat off at Dadans?" Garp nodded sadly hating what he had to make his grandson do.
The two made it to the bandit house and Luffy said his goodbyes to them. He handed Dadan the hat grinning sadly. "Give this to Ace and Sabo and tell them I said sorry but I can't join them on the seas and to not worry about me I'll be just fine!"
Dadan watched the two walk away sadly knowing how much this was going to hurt all three of the brothers. Luffy looked around the trail. "Gramps where will I be going when we get to the marine place?" Garp looked down. "You'll be joining a group called CP9 they work secretly."
The raven frowned. "Will I get to sail?" Garp clenched his fists looking away from the young boy. "You won't be able to do much Luffy. You'll be under constant supervision and won't have any freedom."
Luffy looked down sadly. "Oh." He looked up grinning but it was forced the usual light in his eyes wasn't there. "It's alright gramps! I'm sure I can make some friends and have fun! Even if I'm not going to be free…I I'll manage. I have to!"
Garp felt his anger rising. 'Damn you Sengoku! Making me do something like this to my family!' Luffy stared out at the open sea knowing this was probably going to be the last time in a long time that he saw the sea. Or anyone for that matter.
Sabo was the first one awake the next morning and was instantly on high alert when he didn't see Luffy in his bed. Sabo rushed to his freckled brother shaking him wildly. "Ace wake up Luffy is missing!"
Ace shot up looking frantic. "Luffy's missing? Where is he? When did he leave?" Sabo shook his head worried. "I have no idea I haven't seen him at all. He was here when we went to sleep so he must have left while we were sleeping!" "Why would he do something like that?"
The blonde shook his head not knowing the answer to that. "Let's just go check the bandit's place he might have went there for some reason." Ace nodded in agreement following the blonde out of their tree.
The rushed all the way to the bandit's house. The two brothers knocked frantically on the door. Dogra opened it and frowned seeing the two boy. Sabo and Ace rushed in passed the bandit looking around.
Ace stepped towards Dadan. "Where is Luffy? Has he been here?" Dadan sighed looking down. She handed the strawhat over to the two boys. They stared at it at first in shock then fear.
Ace slammed his hands on the small table infront of her. "Where the hell is Luffy? What is this?" Dadan turned them eyes red and puffy. "That damn geezer of your took him! Luffy chose to go with him to become a marine for some reason neither of them would tell me! He wanted you both to know he was sorry he couldn't go out to sea with you! He didn't want you to worry about him and to just let him go!"
Sabo shook his head in denial. "That's bullshit! There's no way Luffy would do something like that! He loves pirates! He would never willingly leave his hat here it's his treasure!" Dadan glared. "Don't you think I know that? That boy didn't want to leave but for some reason he chose to leave!"
Ace clenched his fists in anger eyes blazing. "That shitty old man! I won't let him steal Luffy's dream away from him! Luffy deserves to be free not some caged bird!" Sabo nodded his eyes stone cold. "Luffy must have been forced. There's only one thing that could make him become a marine and that would be us! He did it to protect us!" Ace turned his back on the bandits heading for the door.
When the two brothers made it out of the house Sabo looked to Ace. "So what's our plan Ace? I know we're not going to just let him go." Ace glared ahead of him. "As we are now we aren't strong enough to get Luffy back. We are going to train ourselves to get stronger! We'll do whatever it takes to get stronger and when we turn 17 we will go and get Luffy back from those bastard! We won't let them get away with this!"
Sabo nodded eyes set in determination. "We'll cut down anyone who gets in our way of saving our little brother!" Ace nodded "we can't stop when we turned 13 we will leave Goa kingdom and find someone to train us so we can become stronger we can't leave Lu alone any longer than seven years!"
Ace passed the strawhat to Sabo. "Hang on to this your better with handling things carefully unlike me." Sabo nodded holding the hat tightly to his chest. All the two brother could think about was Luffy and the bastards who took him!
Both brothers held a fire in the veins and they both vowed they would do anything to save their little brother. He was their brother and they would be damned if they let some stupid marines steal away all his happiness!
