Fusion Burst

Chapter 1

In the mountains far away from the city lies a house on the mountains and there was an old man watching his son Y/n train with holding buckets of water and a cup of water on his head as he was struggling to keep his strength but he lasted for around 3 hours until the old man told him to stop and Y/n did and pants for a bit

Grandpa Gohan: "Well done my son your training is going great Y/n."

Y/n: "Thanks but i feel like i should be fighting people but the problem is that their not like at the same level as I am."

As Grandpa Gohan pats Y/n's back he gave him a speech as they watch the sun came down and Y/n went out for a little flight. But as it was late when Y/n came back the house was destroyed and Grandpa Gohan wasn't moving as Y/n walked over to him

Y/n: "Grandpa please wake up..."

But Y/n soon heard laughter coming from behind him as he looked to see someone with spiked hair as he changed into ssj but with a dark golden aura as Y/n looked at him pissed

Y/n: "Who are you and What have you done to my Grandpa!?!"

???: "Hehe in due time you will know my name Mortal."

After what the person said to Y/n his rage boiles and changed to Ssj with a little Kaioken X4 added to it and charged at him as the mysterious person smirked evily as he blocked Y/n's attacks and the more he smiled the more rage build in Y/n and which cause him to changed to ssj3 and punched him with immense power until the mysterious person changed as his hair was now pink

Y/n: "What the hell is that!"

???: "Well if someone as godly as me this is called Super Sayian God Super Sayian or something better Super Sayian Rośe."

As Y/n looked at him before he riskfully used Kaioken X10 on ssj3 knowing its a dumb move because it can cause damage to himself but he didn't care and began to attack but as Y/n managed to land some good punches on the mysterious figure but he soon did disappeared and knocked him to the ground causing Y/n to change back and for the the pinked hair sayian to be sucked into a portal

???: "No i must bring justice to this world on these Mortals."

Y/n: "JUST SHUT UP!!! KA ME HA ME HA!!!!"

At that moment Y/n blasted a beam of energy to the person knocking him through the portal as it closed and Y/n heard coughing coming from the house and he quickly ran over to Grandpa Gohan as he told Y/n something to do as he said his final words to Y/n before he passed away and Y/n cried to losing someone who was a father to him and after an hour Y/n puts Grandpa Gohan in the dirt for a burial. After Y/n buried his grandfather he looked at the letter he was supposed to give to and while on his other hand holds on to the four star ball as he soon flies off to a section in Tokyo to a burnt down house as Y/n looked around to see a grave as he looked at it and it was the name of the person he was supposed to give the letter to but as he turned around to see a photo of him with what looks like a little girl with black and red hair beside him and Y/n puts the picture away and walk away from the house and heads to somewhere in Honno island to a massive school and sees a body hanged on the front entrance

Y/n: "Well what i can tell by the school and the dead body the students are a little stronger here. Well this is gonna be fun."

Y/n said as he walked in the school to see people kneeling down to a woman on top of the building making a speech that didn't make any sense at all until he saw a girl groaning as a fight was going down with a girl in a somewhat stripper looking uniform fighting against a giant football player as he knocked the girl into the wall but as the football player was charging at her he was preparing to kill her but he was stopped by Y/n as he only used one hand against and pushed him away from the girl

FP: "What the hell man do you want a piece of me as well."

Y/n: "Yeah show me what you can do and *holds out one finger* I'll use one attack to defeat you."

After Y/n said that the students were laughing except for the girl who was injured and her friend helping her as the Football player tried punching Y/n as he blocked many times before he charged something in his hands as hit became a sphere

Y/n: "Big Bang Attack!"

Y/n said as he unleashed his attack on him badly injuring him as the students looked at him scared and the lady on the building was looking at Y/n with interest in her eyes as he turned to check on the girl that was knocked into the wall

Y/n: "Hey you okay?" 

???: "Yeah but I could of handle that creep."

???: "But Ryuko didn't you see what he did to that guy!"

As Y/n looks at them and sighed and walks away as he knew being here at this school is gonna be interesting for himself
