{9 years ago)

In random place

Y/N was training with his brother Giblet.

After 30 minutes they were exhausted.

(I do not own this photo)
Y/N: Ha...We finally..mastered Super Saiyan God without ritual.

Giblet: Of course...We were both born with god ki. We have the blood of super saiyan god in our veins. 

Then they heard a sound from the house


Y/N and Giblet's mother: Hey you both, we have dinner now!!

Y/N and Giblet: OK!!

Then they both went back to their house and have their dinner

While they were eating, their father asked them

Y/N and Giblet's father: You both have mastered Super Saiyan god right?

Both: Yes!!

Y/N and Giblet's father: Good, then the next step is to master Super Saiyan Blue, it will be harder than mastering Super Saiyan God.

Y/N: Even though that is very hard, I still will try to master it!

Giblet: Me too!

Then their father smiled

Y/N and Giblet's father: Good! That's how my son should be!

Y/N and Giblet's mother: Btw, did you both do your homework?

They both were silent

After few second

Y/N and Giblet: Hmmmmmmmm...

Y/N and Giblet's mother:'madly tone'DO YOUR HOMEWORK AFTER DINNER!!

Both: HAI!!

Suddenly their father sensed something

He shouted: YOU GUYS GET DOWN!!!

Then the house exploded


But fortunately, they didn't get any injuries


After the smoke disperse they saw a man with a black coat but couldn't see his face

(I do not own this photo)

Their father tried to attack him but that man shot a death beam through his heart

Y/N and Giblet watched and they felt fury, but they didn't dash and attack him as they know that their attack is useless

The black coat man teleported in front of their mother and grabbed her neck Y/N and Giblet's mother: Run....quick!!

Then she gets killed also

Giblet couldn't control himself anymore 

Giblet:'extremely mad tone'How dare you...HOW DARE YOU KILLED MY DAD AND MUM !!!!

He then transformed to SSG and dashed in front of the black coat guy and gave him an energy blast


But that was useless

It didn't give him any damage

The black coat man teleported behind him quickly and gave him a blast

Then giblet was heavily injured and fell to the ground

Y/N saw the scene but he didn't do anything

The first time he felt his fear

After a few seconds, he tried to help his brother but that was useless

The black coat man kicked him into the burning house

Then Y/N tried to get up but he was heavily injured also

He only can watch the black coat man pick Giblet up and go into the portal

Y/N whispered: Mum...Dad...Brother...

Then he lost his conscious

(present)

Y/N suddenly woke up from the bed

He put his hand on his head

Y/N: Why this dream again...
