we are friends

A week has passed since Seth and Whis fought. Within this time, Seth's started training with Whis. of course, Whis asked for two reasons, which was one his talent and two the food.

"Keep this up, and soon you would have the strength to match a god of destruction," Whis said to Seth, who was wearing strange clothes which were extremely heavy.

"I know, but to think you are actually stronger than a god. Now I most not just surpass you, I most also surpass the world power it's self," seth said with gritted seth as he ran.

"what do you want to much power for?" Whis asked.

"because... I want to be strong to protect my family and friends, and I can't do that if I'm weak. I will never let anyone close to me die again, that I promise." seth said with gritted teeth.

'now I have to come up with a back story for my seth, troublesome.' seth said as he tried to do push-ups.

Whis just smiled at his words as he took out some food seth gave him.

'I should wait for Cell, but it's all cool. I will stay here for 500 years. Why rush thing.' seth thought as he started running around the small planet he was on.

"all of these noises." a purple cat said as he walked out of a house as he rubbed its eyes. (hairless cat)

"A cat?" seth asked, seeing him.

"that's Beerus, the god of destruction you said you want to surpass," Whis said as he hid the food.

"Whis explains," Beerus asked with a frown as he looked at seth.

"that my student, can you believe he is so close to mastering Ultra Instinct in just a short two weeks," Whis said with a huge smile.

"Ultra Instinct?!" Beerus said as he looked Seth up and down.

"I Seth... what to fight?" seth asked with a smile.

"...sure I just got up. A little fight would do," Beerus said with a smile.

seth nodded as he took off the heavy clothes as he started walking towards Beerus.

After a moment of each other looking at each other, seth made the first move as he rushed towards Beerus.

Boom

Beerus was sent sliding backward, but he wasn't injured. Wait narrowed eyes, he looked at seth before disappearing.

'behind me.' seth thought as he sent a kick towards Beerus, he just appeared behind him. a smile appeared on both Beerus and seth face.

"it seems like I have to use around 80% of my power," Beerus said as he punched seth stomach, which seth Dodge at the last moment.

'Ultra Instinct.' Beerus thought as he too used using his level of Ultra Instinct, which was a bit low.

seth and beers started blow for blows until Beerus got the upper hand, giving Seth a nice kick to the stomach.

seth covered his stomach in pain. When Beerus was bout to knock seth to the ground, he froze as he looked at seth, who was eating with Whis.

'a clone... no, it was an illusion. I should have broken out of it if I wasn't so forced on a battle.' Beerus thought as he floated down towards the group.

seth smiled, seeing Beerus had broken out of the illusion. This also helped seth realize just how strong he was.

'I'm equal to a god of destruction, but he was also holding back. And wish is at least five times stronger than Beerus, and then you have his slightly stronger sister than him and their father... I should take my time and grow slowly in this world. When I have the chance to kill Zero, then I will do as I wish.' seth thought with a smile.

"you have skills, but if I used Hakai, I could have destroyed that illusion," Beerus said calmly

As the God of Destruction, Beerus possess the ability to destroy anything, which includes Gods and ghosts. By extending one of his hands, with his four main fingers straight up and his thumb crossing his palm horizontally, Beerus can cause his target to disintegrate into nothing regardless of who or what it is, without any effort or waste of energy. this is hakai

"I know you god of destruction have such cool abilities," seth said as he throws a cookie at him.

"What is this," Beerus asked

"..." whis didn't say a word as that world give up the information that he knew something.

"it's called a cookie, try it," seth said with a smile.

"a cookie?" Beerus said as he eats it as he. His eyes widened.

"incredible, give me more," Beerus said as he started fighting over it with Whis.

"I'm going to train... can you show me the Hakai." seth asked with a smile.

"why?" Beerus asked

"I want to see if I can learn it," seth said with a smile.

In the anime, goku was able to learn it after seeing it. Why can't seth, who has a higher comprehensive ability, then goku do it?

"sure," Beerus said calmly as seth threw a large rook at him.

"Hakai," Beerus said calmly as seth was looking at this with 100% of his attention.

"ok, let's see," seth said as he tapped his foot on the ground as a large tree grew out of the earth.

"Hakai!!" seth yelled as the tree started turning onto nothingness.

"What!!" Whis and Beerus said with wide eyes.

"I was born to be the god of destruction," Seth said with a smile.

"... will I really have to give up my seat of the god of destruction to this kid," Beerus said in a low voice to himself.

"don't worry, we are friends. Why would I take something you want away from you," seth said with a smile as he went to train.

"friends?" Beerus said to himself as he looked at seth.
