In a rush of fists and kicks, Black couldn't withstand my assault. Black's transformation became undone and was on the floor on his knees.
Sage: Hahaha, you being on your knees infront of a mere mortal must mean you are ready for something. I knew you sucked but to be ready to do it literally, hahaha.
Black: AAARRRRRRHHHHHH
I activated my Rinnegan, put my hand on Black's head and used the Ningendo (Human path) to extract Black Zamasu's soul. I pulled it out slowly to make it painful. Black could't yell out but the pain he felt added flavor to the finishing touches. Black's body laid there lifelessly with the soul in my left hand. With my right hand I made an energy blade and chopped the body up into meatballs. After lightly cooking the meatballs with energy I made into a flame, I finished the cooking as I began eating Black. The others were horrified as I finished devouring Black. I threw the soul at Zamasu and with the incoming surge of power coming from me eating Black I needed to channel it into solidifying Migatte no Gokui (Autonomous Ultra Instinct).
The energy pulses through my body as the wounds that were inflicted healed almost instantly, my muscles bulged and Ki burst out. Even the almighty immortal Zamasu was shaking as he held the soul of his counterpart. It seems that I only hit the initial stage of Migatte no Gokui but it was still a stable form. My hair was outlined in silver, now I have to apply it to my True Super Saiyan God form to advance further. In order to prepare for it I turned into regular Super Saiyan God. I plan on solidifying my forms by constantly being in regular Super Saiyan God form. Once I turned back into Super Saiyan God I looked at Zamasu holding his other soul with a smile on my face.
Zamasu: YOU…YOU FUCKING MORTAL!!!
Sage: (I patted my pants as if I was looking for something in my pockets) It seems I ran out of fucks to give. (I looked at Goku) Hey Goku-san are you done with him or is it my turn?
Goku: Haha hell no, we just started.
Sage: (I looked at Zamasu) You should absorb that soul if you want to hold any chance of winning.
Zamasu looked at me as if he wanted to tear my heart out. His plan came to a grinding halt with Black gone. I couldn't help but laugh at his despair. In anger he ate the soul. Zamasu was not that strong but he was immortal and the only way to get rid of him was to undo the immortality which is impossible to gather Super Dragon Balls in such a short amount of time. Other options include sealing him away or I could take his soul out and send him to hell. In order to get Zen-chan to come out though I want to see if this Zamasu will still multiply and spread out like a virus like he did in the original story.
Once Zamasu ingested his other soul he became stronger but not enough to threaten me only enough to have Goku and Vegeta have a good fight. At first Goku had no problem dealing with Zamasu because from appearance the only one who had the majority of fighting experience was Black and since Zamasu is immortal I think he didn't train at all. Black trained his body but I doubt that would strengthen his soul. I cannot completely commit to that assumption because the souls of Kais may act differently. Goku is not having too hard a time but can't give good damage as Zamasu, which I previously said, is immortal granted by the Super Dragon. Vegeta was agitated and attacked together with Goku.
After a few minutes there was no change but the stamina drain on Goku and Vegeta. The situation was looking desperate until I stepped in. In my Super Saiyan God mode Zamasu stood little to no chance of winning. I used an energy blade to chop him to pieces. From the pieces, Zamasu began to multiply. I smiled as the story progressed normally. This universe was fucked when Zamasu came into it so it didn't matter that Zen-chan would erase it.
Sage: Hahaha it doesn't matter how many of you there are, you are still going to lose.
Zamasu: (Multiple Zamasu in unison) With my perfect immortality, how can I lose?
Sage: Please. How are you perfect when you can't beat us? You just have an immortal body nothing more. Take that away and all you are is trash.
I began using Hakai energy to destroy multiple Zamasus. I beat them into a pile and destroyed them but even though I could destroy them they only turn into ash and from that he gathered and went into the atmosphere. At this point there is nothing to be done but call Zen-chan to eliminate him for good. Like in the original story line, Zamasu had multiple faces in the sky covering the planet which was very creepy.
Sage: Goku-san!
Goku: Sage do you have any way to stop him at this point?
Sage: Goku-san use the button Zen-chan gave you. Zamasu may have killed the other Gods of Destruction and the Kais but I highly doubt he would have the balls to try and kill the King of All.
Goku: That's right there is a Zen-chan in this timeline cause no can go up against him.
Sage: Just don't be surprised by what Zen-chan does. I will ready a portal to go back so stay close everyone.
Goku pressed the button and this parallel universe's Zen-chan popped out. I didn't tell the others that this universe is done for because panic and doubt will set in. Once Zen-chan wipes out the universe along with Zamasu, we will just leave that way I can bring parallel Zen-chan back to be friends with the current timeline Zen-chan.
Zen-chan: Who are you? Did you call me here?
Goku: Hey Zen-chan, I'm Son Goku! I'm friends with you in my world.
Zen-chan: Hmmmmm, what happened here? It looks terrible.
Goku: (Pointing at the Zamasu covering the atmosphere) Those guys…they did this.
Zen-chan: Theres so many faces. It's all their fault?
Goku: That's right. They're all bad guys.
Zen-chan: It feels creepy. It really bugs me.
Goku: Right. Don't you think we'd be better off without them?
Zen-chan: Yes, you're right. Better off…without a world like this.
Goku, Vegeta & Trunks: WORLD?!
Sage: This is not gonna be pretty, everyone into the portal.
Zen-chan was charging up his power to eradicate the world. I say world but really it was the whole universe. When we all passed through the portal we landed in Bulma's back yard where we were met with Bulma, Chibi Trunks (little), chibi Pilaf, Mai and Shu. Beerus, Whis and Supreme Kai were there as well waiting on the news of the battle.
Goku: Beerus-sama, we managed to take care of Zamasu!
Beerus: Hmph! From the looks of things, he gave you a run for your money huh. I bet you couldn't manage against him at all with your power.
Goku: Well, we could manage but Sage overpowered him and even used your technique. The moment he turned into ash he made himself into the sky itself.
Sage: The atmosphere, Goku-san.
Goku: Right, that. So after he became that we couldn't touch him so I called the King of All. He wiped out the world in the process though.
Trunks: But by doing so, we were able to defeat Zamasu and we were able to protect the other parallel worlds. So we really didn't really have a choice.
Whis: I suppose having too many parallel worlds wasn't a good thing in the first place.
Beerus: You're right. I guess it's good we had a chance to trim them down.
As the conversation progressed, Bulma figured out how to travel to alternate universes but wasn't there yet according to her. I told Goku that we could bring the Zen-chan from Trunks' alternate universe here so he could be this Zen-chan's friend. Goku thought it was a great idea. After eating and getting dressed I used Yomotsu Hirasaka to pick up Zen-chan.
