Chapter 1:The Beginning

This Story begins with a 10 year old kid with stitches under his left eye look and a straw hat on his head with at his friend in the boat with a lady with green hair next him and a old man on the other side of the kid and other people behind him.

This kid is named Monkey D. Luffy and the person he is looking towards to is his 17 year old 'brother' "Fire fist" Portgas D. Ace.

"I hope you have a fun time being a hero bro."Luffy said as he waved to Ace."Don't get a cold Ace."The lady said waving towards him."Don't do anything stupid,you hear me!"The old man yelled at Ace."Hey Luffy,I hope you can be a great hero when I come back and thank youAce said while waving to everyone on the dock."I'll be a lot stronger when you come back from your journey."Luffy said smiling at Ace.

Luffy just watch Ace leave while barely listening to the other people say their goodbyes and started to walk towards the woods and stops at a rock and hear a voice in his head telling him what to do.So he crouched down a little bit and leaned back and launched his arm at the rock and as it stretched using his Gum Gum quirk,he destroyed the rock with just one punch.He pulled back his arm and looked at the broken rock and smiled.

-A Couple of Hours Later- 4:30 pm

A kid who looked like Luffy's age stands on one side of a riverbank with Luffy being on the other side.The other kid is named Katsuki Bakugo or katsu by luffy and Bakugo's Explosion quirk starts to flare up on his hands."So luffy,do you really think you can actually win against me deku?" Bakugo said with a smirk on his face with his hands beside him."I will beat you this time katsu,count on it."Luffy said putting his left hand forward and other hand by his face and looking at bakugo with a straight face.The two stared at each other for a few seconds before both of them running towards each other and started fighting.
