Kaito used his quirk on Shin I'm that small timeframe.
Shin jumped back and found his arm disintegrating slowly till his elbow. It stopped there.
Kaito only used little ki in that attack as he didn't want to drain all his ki and then end up fighting Kibito in a weakened state.
Shin gripped his arm cried out in pain. "You lowly mortal. You dare do this to a God. You are going to pay for this."
Shin also looked lown on mortals, but not to an extent like Zamasu.
(Even in the show, he looked down on mortals until he saw Goku and Gohan's power.)
Kibito said "Now, I shall remove you from the world of the living." and rushed at Kaito after healing Shin. He only managed to stop the bleeding.
Kibito fired a ki blast at Kaito, who fired his ki blast to block it.
There was an explosion, followed by a dust cloud that blocked his view. Kibito was Shin's bodyguard and knew how to fight.
He used the dust cloud as a cover and got closer to Kaito. He also solidified his ki in his palm and made a sword.
Kaito could sense Kibito coming towards him so, when Kibito came out of the dust cloud, it didn't surprise him.
He prepared himself and stretched out his hand towards Kibito to hold the sword.
Kibito got closer and swung the sword towards Kaito's chest. Then suddenly, Kaito had a shocked expression.
He didn't move his hand to block the sword. Or rather, he couldn't.
He couldn't move his body and was frozen in his place. He looked around and found Shin sitting and extending his arm towards Kaito.
'Shit! How did I forgot this? This idiot can immobilize people. Argh! I was careless.' Kaito thought.
Shin liked the look of fear on Kaito's face and said "Now, prepare to die. We actually thought of asking about the other fruit you stole, but we cal always find it after you are dead."
Kibito thrusts his palm, with ki around it shaped like a sword, through his chest.
It managed to come out from behind and made a hole in the place his heart was supposed to be.
Kaito puked out a mouthful of blood and had an angry look. He was filled with rageand glared at both Shin and Kibito.
Kibito said "Are you glaring at us? Do you really think you can do anything now. Honestly, I wanted to slowly kill you for what you have done to the Supreme Kai. I will get rid ofy pent up anger now." and started slashing at Kaito.
Kibito slashed at various places at incredible speed. Kaito had cuts on almost all over his body.
Shin was also smiling even though his missing arm still pained. He was waiting for Kaito to die so that he can be completely satisfied.
Shin then noticed something strange. He thought 'This mortal is dying and his ki should decrease gradually, but instead of decreasing, it is increasing to a level above mine. What is happening?'
He sensed something was wrong and shouted to Kibito "Kibito, quickly cut off his head."
Kibito turned to look at him and asked "Is something wrong?"
That's when Shin noticed the smile on Kaito's face. Kaito said "Too late my friend."
Shin felt his hold. on Kaito was weakening. He used all his ki to hold Kaito in place and shouted "Move fast Kibito. I can barely hold him in place now."
Kibito rushed towards Kaito as he also felt the growth in Kaito's ki, but was late.
He was thrown back by the force Kaito released when he powered up. He didn't shout when he powered up this time.
He was in his super saiyan form, with red aura around him, but also had a black aura around the red aura.
"What is this ki? How can a mortal have this much ki?" Kibito said.
Shin had a shocked expression, but not for the same reason. He asked "How do you have both gook ki and evil ki in you and how are still alive with a hole in your chest."
Kaito asked "What hole?" and the hole closed with flesh growing and healing the wound.
Kaito said "I thought I had less ki compared to you when you arrived because I didn't want to use the evil ki. Although I can make them cooperate in my body, when I start using it, I will gradually loose control. So, I refrain from using it.
Only now did I realize that it is same as the good ki and can be used if controlled properly. Now I am able to use both and my power has increased to a whole another level."
Kibito said "Shin, I guess we don't have a choice. I was told that in case we are in a life and death situation, we have to take out one earrings on opposite ears and then it is supposed to help us."
"Why didn't I hear about this?" Shin asked.
"I was told it is to be used as the last resort. I guess now is the time." Kibito said and removed the earrings on his left ear while Shin removed the one on his right.
They both waited to see something happen and then suddenly, they moved closer to each other, more like they were pulled closer.
Then there was a light which blinded Kaito and when the light died down, there was a figure that appeared from the light.
"Oh! It sure is great to see them fuse." Kaito said.
"Fusion, what do you mean?" they said and then looked at themselves.
"What happened? Did we really fuse as that mortal said?" They said.
"Do you really don't know about the Potara earrings. When two people wear them on opposite ears, they fuse. Their power also increases but, your fusion is going to be permanent." Kaito said.
