A/N: Decided to make the MC 17 years old.
The Hashira were having a meeting about the Kamado siblings when a man fell from the roof and landed in front of Kagaya who seemed surprised. The hashira immediately took out their weapons and faced Gojo who slowly got up while wincing in pain. The Hashira got a good look at the blindfolded man. Gojo took a quick sweep of his surroundings and immediately sighed in relief. The flame hashira asked with a big smile on his face "Who are you!" Gojo replied with an equally big smile "Gojo Satoru!" The flame hashira spoke to the others "I like his personality." The others shook their heads in disappointment.
Kagaya asked another question "What are you doing here?" Gojo thought of the most believable excuse he could and spoke out loud "I am here to help as I am a Jujutsu Sorceror that deals with cursed spirits and supernatural!" Kagaya nodded as he took this all in. Gojo continued and said "My goal is to help you get rid of Muzan then I'll be on my way." The other Hashira were skeptical as this man was saying that he would defeat Muzan and his tone was implying that it would be easy.
Sanemi asked the question that everyone was wondering about. "Why are you so confident in defeating Muzan?" Gojo smiled as he turned around and spoke outloud "Cause like I said I am the strongest Jujustu Sorceror and we shamans use Jujutsu techniques to exorcise cursed spirits and some are stronger than Muzan." Sanemi was skeptical and Gojo noticed that. "I'll let you try to stab me. Don't worry I'll be fine." Sanemi steeled himself in case of murder and rushed to stab Gojo in a spot that would not be fatal.
The other Hashira watched as Sanemi's katana was about to pierce the Gojo's throat only to stop. Giyu spoke "Why did you stop Sanemi he said that he was confident in surviving." Giyu stopped speaking when he noticed the others looking at Sanemi's trembling hands indicating that he was trying to pierce something.
Gojo decided to enlighten them, "This is my inherited Technique, Infinity" Shinobu stood up and made her way to Gojo before she tried to stab him as well. The blade had the same reaction as Sanemi's. Soon all the Hashira's were taking turns in experiencing Infinity.
Kagaya was about to continue until Gojo's stomach rumbled indicating that he was hungry. His face grew a bit shy as this was incredibly awkward. Shinobu volunteered to take Gojo to the Butterfly Estate. Shinobu took him to Aoi who greeted Gojo and provided some biscuits while he waited for the meeting to end. Shinobu simply gave a smile and a wave before leaving back to the meeting.
Aoi asked Gojo the moment Shinobu left. "Why do you wear a blindfold?" Gojo gave a smile and said "I'm not blind but I won't say either." Aoi just stared while trying to think of the possible uses of the blindfold before giving up in the end.

Timeskip:
Gojo had met Kanao and was joining her in visiting the Kamado boy. Kanao opened the door and noticed that Tanjiro was awake. Gojo studied Kanao's expressions and noticed that him being here was really awkward. Gojo walked out and sighed "I really do not fit here"
Tanjiro had broken his sword so he was going to visit the blacksmith village despite the warning letters.
"Hate, Hate, Hate, you can got to hell."
"Fuck you, Fuck you go to hell."
"I have no sword for you."
Gojo saw this and decided "I need a souvenir!" so he got permission from Kagaya to visit the village with Tanjiro. The Kakushi didn't know that Gojo could still sense and see with his blindfold on so they let him just follow by putting his hands on a Kakushi. Gojo spent his time memorising the path to the village just in case.
The Kakushi finally stopped as they left Gojo and Tanjiro there. The two visited the chief before heading to the hot springs. Kanroji, the love pillar suddenly came bounding down while Tanjiro was shouting for her to stop lest her breasts spill out. The two of them walked to the springs and changed when Tanjiro noticed Genya and jumped in while shouting. Gojo just silently changed and enjoyed the springs in piece with only Infinity of his head. Gojo watched in amusement as he saw Tanjiro getting his head smashed into the water by Genya.
Genya noticed the other boy with a blindfold and white hair before giving him a glare. Gojo noticed the glare and just gave a dazzling smile that seemed to be the bane of Genya's existence.
Gojo got out and looked for a souvenir to take with him before he could hopefully settle in a home world. He saw Tanjiro talking to Kanroji and figured that it was about the Yoriichi bot.
Gojo finished his purchase of a small custom mini keychain with a tiny katana attached. Noticing that Tanjiro had almost disappeared out of sight he quickly followed and saw the emotionless boy Muichiro.
Gojo just went and followed Muichiro after he got the key. Muichiro was confused as to why Gojo was following him but simply shrugged it off.
Gojo decided to wait until nighttime and slept for the rest of the time.

Gojo awoke to see the house around him being blown away.
The fan demon blew away the house only to find a man wearing boxers? Gojo saw the demon and quickly put on his clothes before asking "Well that was awkward?" The demon lunged at Gojo with the intent to kill.
Like always the attack stopped just before Gojo as he gripped the demon's head before ripping it off. Tanjiro just looked while Gojo proceeded to head back to the butterfly estate.
Gojo found himself actively hunting for MJ after staying here for a while but he could not find MJ.

Timeskip:
Muzan was facing off with Tanjiro and the other pillars who had survived and when all hope was lost they saw the man that was supposed to destroy Muzan. Muzan turned his head to the newcomer.
[GOJO SATORU ENTERS THE FIGHT]
Gojo spoke out loud "I have surpassed your moon walk MJ" Muzan was looking confused until Gojo started sliding backwards but it looked like he was trying to move forward. Gojo spent countless hours practising the moonwalk before combining it with infinity to make it the infinite moonwalk. His feet were not touching the ground as they glided over the air.
Muzan was utterly confused and sent a tentacle at Gojo who continued to moonwalk around Muzan before disappearing. The water pillar was confused as they saw Gojo disappear then reappear a few seconds later with Shinobu.
Gojo had found the corpse of the barely alive Shinobu and used a reverse technique before taking her back.
Gojo simply was tired, he wanted to go to a good world and settle down in some peaceful place eating sweets and basking in the cool wind all day. Maybe even a beach, then he remembered the reason why he was still here. Muzan watched as Gojo's veins started popping from anger.
"Curse Technique Amplification: Blue"
"Curse Technique Reversal: Red"
The Hashira watched as purple energy started forming a vortex in front of Gojo before his words broke them out of their stupor.
"Imaginary Curse Technique: Hollow Purple"
Gojo appeared in front of Muzan before releasing the death beam in point blank range. The Hashira were slack jawed as they watched the forest being decimated with the beam of erasure.
After the sight they were left with a gaping straight gash in the ground extending through the whole forest.
The hashira were looking at Gojo as if he was an alien.
Gojo just chuckled and thought.
"Awkward!"

Ophis could be seen looking in a cupboard. "Onii-chan?" Ophis was going around every cupboard she could find and opening them.
The ORC club got a shock when Ophis appeared and looked in their cupboard "Onii-chan?" Ophis looked in the fridge thinking something would be there. A beautiful cheesecake was there waiting for her. "Cheesecake"
