Satoru vs Aoi(Disguised Satoru).

I see that some of you in the comments are confused about how Satoru could just kill his fellow Clan members without care.

Well, your answer is in chapter 2 where he wiped out half the Universe. For Satoru killing people or organisms, he doesn't know is easier than killing people or organisms he is acquainted with or is attached to.

This will be shown much more clearly in the future.

Also, Fugaku isn't dead, he is just near death. And for the others, Satoru specifically avoided making friends or being familiar with anyone in the Clan so that when the time comes he wouldn't be hesitant.

--------------

Seeing the Clan Head fall many of the Uchiha Clan Forces halted in shock. This gave Satoru the chance to thin them out.

Slashing and scratching them with Murasame, Satoru managed to hit 12 people of the Uchiha Clan. Black marks started to appear in their bodies as they all died within seconds.

With Fugaku out of the game, nervousness hit the Uchiha Shinobi as their formation broke apart. Satoru slashed another guy and took his sword and slashed another guy.

Dual wielding Satoru proceeded with the slaughter and at the end of it, all that was left was Satoru with two blooded swords and a lot of dead including the Cursed Corpses and half dead people.

"Oops I was supposed to leave one for questioning," Satoru acted his arrogance of his Shadow Clone being bought over.

"I guess I will just have to heal up one of them with Reverse Cursed technique," Satoru said out loud so that the half dead people he had left alive as witnessess could hear him.

As Satoru walked towards one of the half dead people, a child-like voice came from behind.

"Oto-san," A white-haired blindfolded boy went running towards Fugaku's body and a red aura appeared in his hands as Fugaku's injuries healed and he was safe.

"Ho, if it isn't the brat I was looking for, perfect timing I was just done warming up,".

"..." Satoru said nothing and focused on healing Fugaku.

"Well, then introductions shall we, I am Aoi, nice to meet you Gojo Satoru and farewell because, You're next Gojo Satoru!,".

Satoru was done healing Fugaku as he stood up and stared at the man named Aoi. He clenched his fist tight as muttered,

"Yarou, AOI!," Satoru started to slowly walk towards Aoi.

"Ho? You are approaching me? Instead of running you're coming right to me? Even after seeing the scene right in front of you,"

"I can't beat the shit out of you without getting closer,"

"Ho ho! Then come as close as you like," Aoi also started walking towards Satoru as they both prepared for a clash.

While the two approached each other the people who had brought Satoru(Clone) over here were holding there breaths as they tried to escape for the monster named Aoi.

And Fugaku who was just healed up slowly opened his eyes and weakly looked around and saw Satoru and the enemy approaching each other, he panicked as he tried to move but couldn't.

Satoru and Aoi were now 2 meters apart from each other but both didn't stop or slow down but instead,

Satoru took off his blindfold and punched whereas Aoi shook off the blood on his swords and swung them.

They exchanged several blows but neither of them got hurt until. Aoi found Satoru's torso open and kicked him towards a house.

Breaking the concrete walls of the house Satoru flew inside as Aoi rushed in and came several noises of metal clashing with eachother.

And Satoru flew out of the house breaking through the concrete walls again. And then proceeded to be kicked again.

"As I thought you have only recently awoken your technique and Rikugan haven't you," Aoi shouted out loud.

"If you were using it, you would have no problem defending yourself from my attacks," Aoi said stepping on Satoru's chest pinning him down.

"But it looks like you have no idea about it, you Inherited Technique that is," Aoi lifted Murasame and stabbed it towards Satoru but before Murasame could reach Satoru,

'Amaterasu'

Aoi somersaulted out of there as black flames appeared in his previous position. The source of these black flames was none other than Fugaku.

It was now a 2v1 not that it made difference..., unless,

A sword attack came towards the right side of Aoi which he blocked with Murasame and attempted to stab the attacker mid-air with his regular sword which was dodged by a hair lenght.

Landing on the ground the attacker backflipped and made some distance before throwing a Kunai tied with a paper bomb.

BOOOOM!!

The paper bomb exploded as smoke covered the area. Satoru looked at the individual who had just entered the scene.

"Itachi nii-san,"

The one who had entered the scene just now was the Chad, the one we hated at first then we loved, the goat himself, Uchiha Itachi.

"Satoru To-san are you alright,"

"Be careful he won't even be injured by this," as Satoru was saying Aoi came out from the smoke swinging Murasame.

'Amaterasu'

Fugaku used Amaterasu, Satoru threw a stone, and Itachi tried Genjutsu.

The genjutsu didn't work since you know, no Chakra and all, the stone did nothing but Amaterasu did make Aoi dodge.

"Itachi, genjutsu won't work on him, this one doesn't have Chakra but there's something else entirely involved. He can use ninjutsu or something similar to ninjutsu," Itachi nodded as he understood what Fugaku relayed to him and started strategizing.

Satoru looked at Itachi and thought, 'So our plan was busted from the beginning, huh, well it is a good thing I switched it,'

Satoru and Fugaku stood up as Itachi asked,

"How much longer,"

"As long as possible, I can heal up anytime and heal anybody anytime," Satoru said.

"I am better than before and keep on going, also be careful of that sword, one strike and you're dead," Fugaku said.

"hmhmhmhm, hahahaha, you still going at it,"

"Uchiha Clan Head, wouldn't it have been better to sacrifice your son and save your own and your subordinates' lives instead of this," Aoi said pointing at all the corpses around them.

"But seeing their arrogant attitude, I can't say this scene wouldn't have repeated itself, you guys have been on the top for quite some time and deteriorated,

"Calling yourselves the great Uchihas knowing nothing about reality and here you all are, the greatest strongest clan in Konoha at present taken down by a single person, just like Ultron said,

"You rise... only to fall,"
