Luffy stood in front of his battalion. Normally, as an Admiral in the Marines, he has the ability to command several thousand marines, but he chose to only take 750 men to make a headquarter for himself. Zoro returned before Luffy returned and since there were no casualties for the Marines, Luffy had the same amount of troops he did before rescuing the villagers.
Anyway, Luffy stood in front of his troops and waited for Ace to come onto his ship. Luffy stood, excited that he was able to see his older brother after not having seen him for a long time. Robin held Luffy's arm as several jealous marines tried to glare at their admiral. However, one look from him made those marines shake with dread as they knew that they were no match against their admiral.
When Ace got on board, several marines attacked with their guns and swords. Smirking, Ace jumped up and let the marines crash into each other. When one of the officers jumped up to face him, the officer swung his sword at Ace. The sword went through his body and melted after around 5 seconds. Ace, still smirking, kicked the officer to the deck. When he got down, Luffy ran forward to meet him head on. Ace continued to maintain his smirk and made contact with Luffy. For 2 hours, they fought to a standstill. Both were holding back many of their destructive powers. Finally, exhausted from the battle, both fighters laid down next to each other. Looking at each other, Luffy and Ace grinned and started laughing as they tiredly hugged each other. The marines, under the command of Robin, silently crept away. Before leaving, Robin glanced at her boyfriend wistfully, then continued on her way back to their HQ. Both brothers put arms around each other's shoulder as they started to head toward Luffy's HQ.
Now you may be wondering why the marines did not arrest Ace. That is because Ace was a member of the Whitebeard Pirates and since Luffy is an extremely high ranking officer in the Marines, the World Government cannot touch Ace or the Whitebeards. Therefore, both sides formed a pact where the World Government will acknowledge the Whitebeards as allies and in return, the Whitebeards were to help out the World Government by bringing in other pirates that had bounties on them.
As both brothers got to Luffy's HQ, Robin was outside, waiting for Luffy. He smiled and saw Robin blush but smile as well. Luffy introduced Robin to Ace and told him that he now had a girlfriend. Ace smirked and asked, "So are you not dense around women anymore?"
Luffy grinned and said, "Shishishishishishishishi, Robin is the only one who I will be with. Any other women doesn't catch my interest."
When Luffy had said that, Robin's blush increased and her smile grew wider. She thought, em"I can't believe I am so lucky to have a boyfriend like Luffy. I love him so much."
Ace smiled at this and grabbed his brother, putting him into a headlock. Then, Ace noogied Luffy. Afterwards, Ace looked at Robin and bowed his head slightly saying, "Please take care of this brat for me. And please make him happy."
Robin smiled gracefully and replied, "I wouldn't dream of hurting the only man I could ever love. Thank you for accepting our relationship."
Luffy grabbed Robin's hand and brought her closer. Robin blushed but placed her head on his shoulder. Ace smiled, then asked Luffy when they would be eating. Luffy, becoming wide-eyed, immediately ran to the kitchen where he demanded the cooks start preparing a feast.
"I want a LOT of MEAT!"
Ace shook his head, but smiled as his brother was happy with his life and now he had a girlfriend.
"Should I tell him the news?" thought Ace. Seeing his brother acting immature, he shook his head and said to himself, "I'll do that later."
