Garp punched Ao and Sabo simultaneously in the head as they both were sent flying, They hit Ace and Luffy on their Air trajectory.
"Bwahaha, You four are no match for me." Garp. said as he laughed.
"Luffy, Cover for me, Ace and Sabo, Attack him from the back." Ao commanded the three who nodded and got to work.
"It is Futile, Soru."
"Ace, Duck." Sabo said as Garp appeared before Ace and punched him on the head, he swiftly turned around and kicked Ao.
"Ao!" Sabo said as he was flung back by the residual force and air pressure generated by Garp's kick.
'Just as I thought, He is hitting Ao harder.' Sabo thought as he got up and wiped the sweat on his forehead with his sleeve.
"Grandpappy!!" Luffy said as he charged at Garp, His fest charged up and was ready to attack.
"What did you say!? Brat." Garp Siad as he flicked Luffy, Luffy was sent flying.
"Luffy!" Ao said as he caught the kid.
"Thanku!" Luffy Thanked Ao.
Ao put Luffy on the ground and balled up his fist, the fist glowed white before turning pitch black.
"Haki? Well that is surprising!" Garp said as he coated his arm with pitch black haki as well.
"Superman punch." Ao said as the muscles in his arms bulged and veins popped up on it, this was a new technique he thought of recently.
"Bwahaha." Garp laughed as he appeared before Ao in a flash.
They both simultaneously punched each other but their fists clashed.
"Where did you learn haki brat?" Garp asked while clashing.
"A pirate from the grandline taught me a few years ago." Ao lied.
"Bwahaha, Guys three times your age don't learn haki after years of training and you learnt it a few years ago? I call that bullshit." Garp said as his fist overpowered Ao's fist. Ao was sent flying back.
"I gotchu' Ao!" Luffy said as he ran where Ao was going to land and stood there.
"What are you doing lu-" Ao hit Luffy, both of them were flying now.
"AHH!" Ace screamed as he Hit the Flying Duo.
"Ac-!" Sabo couldn't finish saying Ace's name as he was also hit by the flying tiro.
"Ow!" The four of them said as they hit a tree.
"Bwahahaha." Garp laughed with his hands on his waist's.

"Are you leaving Now?" Luffy asked Garp with sad eyes. Garp had a bag slung over his back.
"I am a marine brat, I cannot slack off and play all day with you Brats." Garp said as he hit Luffy one last time with his fist of love.
"Why'd you hit me for?" Luffy asked Garp with a tear and a lump on his head.
"I didn't hit you brat, This is my fist of love." Garp said as he looked at his fist.
"You brats take care, I will be leaving, Now." Garp said as he left the area.
"Okay, Bye." Ao said as he looked at the leaving figure of Garp.
He looked back with a smile adoring his face, Ace and Sabo had similar looks.
"You guys's know what time it is?" Ao asked the three of them.
"Moon." Luffy said.
"IT'S PARTY TIME!" Ace, Sabo and Ao said loudly.
"And it is Noon, Not moon you idiot."
