Luffy watched as three thirteen year olds jumped down from the roof, he wanted to join but being at the small singular number of age eight he wasn't allowed too. So he came to a conclusion why not stop them?
It started with a simple sentence of: "Hey guys want to play with me?"
Obviously being shot down and ignored made the small child puff out his chest in annoyance and anger. Brows furrowing, eye twitching, pouting lips, puffed out cheeks he watched as the three boys yet again jumped down from the roof.
Thus with tons of stupid determination he marched to where he surprisingly calculated perfectly where they would land and laid down, his tiny limbs spreading out as his eyes set on oncoming trio obviously thinking they would stop and play with him.
That wasn't what happened though, all three the older boys jumped. It was too late to move and they couldn't stop gravity and that's how the weight of three barely teenagers fell on top of a small fragile left leg.
Ace and Sabo ran towards Makino, Ace screaming: "I didn't mean too, I couldn't stop in time. I'm so sorry!" Over and over again Sabo just had a pained expression on his face while he tried keeping in the tears the frantic brunet in front of him couldn't stop.
The explanation would've been finished quicker if Ace hadn't kept screaming and yelling apologies while his older brother kept trying to explain what happened, Makino gently placed her hand against Ace's mouth silencing him in hopes that Sabo could finally finish the story only for a few uncontrolled hiccups and whimpers interrupting the short. "We jumped on Lu's leg and broke it."
By the time Makino got towards her youngest son only to find him out cold – probably from the pain while Marco - the boys best friend - just sat there looking guilty. The woman gave him a gentle smile before rushing to get little Luffy to the hospital. And that was how he ended up wearing a cast for six months and couldn't run around... karma much? Or just stupidity of an eight year old?
This was how i broke my leg, I dont know what ran through my mind to come up with the splendid idea either...
