"So this is the one?" Luffy asked Sengoku as Sengoku had a child in his hand.
"Yes. This is Donquite Rosinate. He tells me his brother killed their father and has Hao." Sengoku said as he put the child in bed.
"So what are you gonna do now?"
"I am gonna prepare him for going Undercover. He will be my Undercover Guy."
5 Year Later…
"Admiral Luffy. Roger Pirates and Golden Lion Pirates are fighting in the Edd War. The Gorosei would like you to go take care of it. And bring back at least one of them." Luffy sighed. Same shit different day.
"I thought they would ask Admiral Sengoku to take care of it." Luffy said as he bit into his candy.
"They think sending you will be more effective than sending Admiral Sengoku."
"Ok fine. Where is Edd War?"
"That way sir."
Luffy proceeded to run to Edd War to see Roger starting to be outclassed. He landed besides Roger.
"Seems like you need a hand." Luffy then smashed every ship in Shiki's Crew. He then approached Shiki and bashed him hard and disabled his Haki for some time . Luffy took a Steering Wheel and slammed it into Shiki. He then took hold of the Steering Wheel and pulled him to Impel Down.
1 year later…
"You both are so cute. Who is cute? You are." Luffy played with Chiffon and Lola. Their father was responsible for them till they were old enough to Join The Big Mom Pirates. It was the Policy of Charlotte Lin Lin. Then Luffy just tilted his head to the Side and dodged a Mochi Fist.
"You are too young to try to land a hit on me. I have fought strong opponents like Kaido for 20 years and have been an Admiral for 12 years. You need to get better." Luffy said to an annoyed Katakuri.
"Don't annoy Uncle Luffy Katakuri." Big Mom said as she came with a Plate full of Candy Bars. Luffy took one and munched it. Then his Den Den Mushi rang.
"Sir Roger Pirates have just killed a Squadron of Marines and the one who escaped said that Whitebeard Pirates were also arriving there."
"Sigh, I will go stop them." Luffy took a bunch of Candy Bars and chucked them into his mouth. He chewed and swallowed as he Soru to them. He reached just in time to feel their Haki flare up and the two captains attacking each other with their Weapons.
"You should think about others too." Luffy said as both the Murakumogiri and Ace hit the Ground. Both of them looked to see the Marine Admiral and smiled.
"How about you fight without Devil Fruit like the Old times?" Roger said as Shirohige got ready too.
"Everyone get together and attack the Admiral." Both of the captains said at the same time.
3 days later…
Marco and many other lay on the ground with lump on their head. Rayleigh was also on the ground but still Conscious unlike the others. Oden was writing furiously about the power of the Marine Admiral. He also scribbled a picture of him.
Roger and Shirohige were panting as Luffy had his knucknyon and was also panting. "You are as Strong as ever. This is your win." Both the Captain said as they sat down. Luffy wiped his forehead as he started walking on the Air and back to Marineford.
1 Year Later…
"So I am to catch the Pirate King, Gol D Roger without fail. Sure why not?" Luffy said as he started walking towards where Roger was.
1 day later…
Admiral Luffy walked in with Gol D Roger as he had to destroy an Island to capture Roger. He walked to Kong and tossed Roger to the ground. "You know I was going to Surrender myself. You didn't have to send him." Roger said to Kong.
"Well you surrender or him capturing you the result is same."
"Actually can I meet Garp before I am executed."
"Sure."
1 year later…
Roger was about to be Executed. He was brought to the Stand. Liffey could see many famous Rookie Pirate in the Crowd. But his focus was only on one of them. He walked to him. He approached the 19 year old boy.
"You seem quite strong. Specially that sword of yours. What's its name?"
"Yoru."
"Ah. Quite a good sword. And how about you? What's your name and what are you upto?"
"I am Dracule Mihawk. I was thinking of being a Pirate and challenging some strong people to get strong myself."
"How about you fight strong people as a Marine? I can help you get stronger."
Mihawk observed the man for some time before nodding his head. "Very well. It seems I will benefit from that. So I am going to join the Marines instead."
Then the Den Den Mushi in Luffy's pocket rang as he brought it out. "Sir Golden Lion Shiki has escaped and is going on a rampage throughout Marineford. You are needed here. Please come quick."
Luffy sighed as he started walking up the s as it and towards Marineford. He arrived just in time to see Shiki about yo Face Sengoku and Garp. Then he made a down motion with his hands and Shiki was smashed by an unknown force.
"Take him to Impel Down." Luffy said as he walked towards his office.
1 year later…
"The Piracy has gotten out of hand so the Gorosei has decided to start a Pirate group of our own, The Shichibukai or Seven Warlords of the Sea." Kong said as many started to shout denials at him. Then Luffy raised his hands.
"I actually have a person in My Mind for a Shichibukai. The Pirate, Big Mom Charlotte Lin Lin." As soon as he said that, everyone started to be scared.
"Are you sure about Admiral Luffy?"
"Yes. I can get her approval if that's what you need."
"Fine. We were gonna name Big Mom Charlotte Lin Lin, Shirohige Edward Newgate, Clay Man Jolly Chris and Kaido of the Beast The Four Emperor of the Seas or Yonkou . But now it seems that we need to replace Big Mom with King of Hell Yagami Valor. Each of them has a bounty of over 2 Billion."
"Well then the current Shichibukai Member is Big Mom. Get some others to join as well."
1 year later…
Luffy looked on as he led the buster call at Ohara. As soon as the Buster Call began he got a message from Saul that Ohara was innocent and that Luffy had just killed many innocent people. That broke Luffy's heart. He got ready to quit as he had done what he warned others not to. He walked in with Zephyr. Both of them walking in with a letter.
"So you decided to quit too." Luffy said to Zephyr.
"I just felt that Marine is not as Good as Before."
"Same."
Both of them gave there resignation to Kong. Kong sighed. "I was hoping you would succeed me as A Fllet Admiral but it seems I will have to make Sengoku Fleet admiral and get three New Admirals. You choose them."
"Actually sit I would like a permit to sail around and recruit and train some Marines."
"Ok. You have been granted that request."
"Thank you sir."
Next Day…
"Today, Fleet Admiral Kong has been promoted to an even higher Post. As such he would like to name Admiral Sengoku as the Next Fleet Admiral. Please come onto the Stage Admiral Sengoku." Sengoku went onto the stage and took the Fleet Admiral Coat as he removed his Admiral Coat.
"The Gorosei and Kong have decided that the Admiral that succeeds Sengoku will be Vice Admiral Sakazuki. They have also decided to Give Code Names to the Marine Admirals. Hence the Vice Admiral Sakazuki will now be Admiral Akainu. Please come onto the Stage."
Sakazuki went onto the Stage and took the Admiral Coat and drapped it over his Shoulders.
"Today Admiral Zephyr and Admiral Luffy will be retiring from their post and have already choosen their successors. And hence Vice Admiral Brosalino will be Admiral Kizaru and Vice Admiral Kizan will be Admiral Aokiko from this point forward. Please come onto the stage." The four got onto the Stage as Zephyr gave his coat to Kizaru and Luffy gave his coat to Aokiji.
"You three have also been three Devil Fruit please choose one and eat it."
Luffy came out of the hall as soon as he gave away his coat. Luffy walked out and decided that he just enjoy his life now. No more being sent after Shirohige and all. Luffy smilled widely as he jumped and started walking on air.
I have decided to keep this shirt as now the Protagonists will be introduced. And I have already planned oh how to replace Big Mom later on in Whole Cake Island and then Wano. If you have any idea tell me.
