I don't own Dragon Ball and Kimetsu No Yaiba.

Okay this end is a bit cringe.

Carrying on the memories:

75 years have passed since Muzan's death. Tanjiro, Kaneo, Inosuke, Zenitsu and everyone else has died of old age. Demon Nezuko in her disguise when to everyone's funerals. But human Nezuko is slowly dying to old age. Demon Nezuko ends up visiting in her. Especially after Nezuko called for Suruka Sona to visit her. Which is Demon Nezuko's fake name. Her disguise is fully human looking purple eyes with lightly paled skin. Along with short ginger hair.

Demon Nezuko arrives and sits down next to the bed. Everyone leaves allowing them a private conversation.

"You came?" Said a dying Nezuko.

"Yeah." Demon Nezuko responded.

"Good. Because I want to tell you this. Keep everyone alive in your heart. Remember don't forget. Especially remember me to remember the human inside yourself. Keep your heart burning. Enjoy your life, no matter what happens." Nezuko managed to say while badly coughing.

"Don't worry. I will remember everyone. Mostly you to remember the human within me. It's hard when everyone dies of old age and I keep going. It's so painful. But I must continue through the pain no matter what." Demon Nezuko said with tears coming out of eyes.

"That's a good demon me. Always keeping your promises like you would. Also, please keep an eye on mine, brother's and friends descendants. We'll all be grateful for that. Also, if you ever see, Goku again. Tell him we all had great life's. It might make him happy knowing that we all did." Nezuko managed to say while badly coughing.

"Yes, I will do all of that." Demon Nezuko promised.

She looks on at her human self and starts massively crying since her human self has just passed away. Before she made the promise. A group of people come in the room and have started taking the now late Nezuko away.

Nezuko walks out side in a massive amount of tears. She looks to her left and sees human Nezuko's kids who are in their 50's crying like her.

The next day she attended her human count part funeral.

Nezuko ended up buried in the same grave has her husband Zenitsu. Tanjiro's and Kaneo's grave are next to theirs same with Inosuke's and Aoi's grave. Demon Nezuko left flowers on all three graves and walked away in tears.

Years later Nezuko kept her promise to her human self. By keeping on eye on the family.

2016:

Nezuko is walking along. But all of a sudden there's an earthquake with lightning and a massive change in the weather around the whole world.

'Wait I know this energy from anywhere. It's, Goku! But who is he fighting. I sense someone mixed with, Goku.' Nezuko thought while running in the direction she senses Goku.

"Well, well, well. You really think that Super Saiyan Three will save you?" Said a mystery person with a voice or two people mashed into one. The person is wearing a dark gi with a red top along with red boots and armbands along with some red earrings on both ears. And spiky red hair.

"I think I stand a chance. Actually I believe I can beat you, evil Vegito!" Shouted Goku.

"I want to see you try! I'm only using 10% of Super Saiyan." Said a smirking Vegito.

"But you don't know the my full power. Believe me you might never push me to use it."

Vegito charges at Goku who ends up avoiding the punch and kick along with landing a solid punch in Vegito's stomach. Both end up firing Ki blasts at each other.

"That's it! I'm ending you now!" Vegito shouts as he goes Perfected Super Saiyan Three.

"That's how you want it, huh?" Goku shouted has he gone Super Saiyan God.

"Really? I know that you have, Super Saiyan Blue."

"I'm saving that for later."

They both charge at each other. Both ended up and punched each other in the face. Goku ends up taking it the worst. They both end up clashing arm to arm and leg to leg. Even head to head. Goku ended up blasting and destroyed the Potara earrings.

"Well of course that didn't work." Goku said as he got heavily punched in the face.

Goku turns Super Saiyan Blue and crashes Vegito into the ground.

'Thank god we're fighting in a close to a mountain no where near anybody.' Goku thought has he flew back avoiding a punch and a Ki blast.

"Oh, come on? You don't have Saiyan God or Blue? Just Super Saiyan Four?" Goku asked.

"I have one form left. But this is enough to kill you." Said an angry Vegito.

"Okay, Super Saiyan Five is your last transformation like, Evil Goku's."

"So what if it!"

They both clash.

"Oh, so you gone straight into Kiao-Ken?"

"Kiao-Ken times Twenty-five!" Goku shouted.

"Times Twenty-five? I thought your max was times twenty?"

They both end up clashing multiple times over. Goku is losing everything time. Goku ended up avoiding a Ki blade and drops out of Kiao-Ken.

"So this is how you go out? Pathetic, so weak. Waste of time." Said Vegito who's now going in for the killing blow. But his attack is stop and his hand starts to be getting crushed.

"My hand! Now what are you in?"

"Super Saiyan Blue, Mystic perfected!" Goku replied.

"Well I most respond." Vegito screams as he goes Super Saiyan Five. Sliver fur around the body.

"Just like evil me." Goku said when shaking his head.

'I sense someone.' Goku and Vegito thought.

"Looks like I'm going to be killing a little innocent stupid girl."

"No!"

'Wait that's, Nezuko?'

Vegito charges a blast and fires it at Nezuko. Who disappears and appears behind Evil Vegito. Vegito turns around and sees horns on both sides of the girl now woman's head with red and green leaf patterns on her body along with red eyes instead on purple.

"Wait what are you?"

"A friend of, Goku's." Nezuko replied.

"Kiao-Ken times 100!" Nezuko shouted.

She goes to kick Vegito in the back but he disappeared and reappeared behind her. But Goku ends up kicking Vegito away and throws Nezuko a Potara earring and puts one on his left ear. Nezuko puts the other one on her right ear.

"Oh no! Don't tell me they fused. Even though I wonder what they look like?"

Vegito sees the fusion and can't stop laughing.

The fusion has Goku's blue top with a pink kimono above it. Along with red eyes and spiky hair will long hair down the back. Along with lightning sparking off the body.

'Shit! There fusion is so broken. Their combined potential unleashed with Mystic is insane.' Vegito thought in massive panic. Has he received a punch to the face and a kick in the right hip.

"Hmm. Your fusion dance name was Nego Kamson. Gozuko Sonado. I can't come with anything better. I want to use Nego Kamson again but I can't." Gozuko said.

"Gozuko? You should have stuck with Nego. Also Kiao-Ken times 100!" Vegito screamed.

Gozuko goes Super Saiyan Mystic with Nezuko's full demon transformation. And they both clash. Gozuko ends up punching a hole straight through Vegito's shoulder and smirked. Vegito falls back to base. Gozuko goes back to base.

"Your finished. I'm going to end you to revenge all of the Goku's and Vegeta's you killed." Gozuko said has he fired a Ki blast vaporising Evil Vegito.

Gozuko defused.

"So, Nezuko how have you been doing?"

"I'm fine. Everyone died of old age. My human self died 25 years ago. They all lived great lives. I promised her to tell you that. But she passed away before I could make the promise. But I did it." Nezuko explained.

Goku smiled. "Well it was great that they lived fantastic lives. But what about you?"

"I'm doing well. I should be part watching their descendants. But unfortunately I have to move away. So I don't get busted. So that's out of the window."

"Well has you tell. That I won the Tournament of Power."

"Makes sense or else you won't be here. But I know that you have to go very soon."

"You aren't wrong."

"Wait I have nowhere to go!"

"You can't come with me. You have a future of quirks to be involved in. What year is this?"

"2016, why?"

"Just wait to, 2060 for that to happen. And oh an alternative version of this earth not linked to quirks but you there as sadly gotten a virus called COV19 that came from China. Just hope it doesn't happen here. If it does go to China and destroy it. You'll have to somewhere in December 2019." Said Goku.

"Well then, I guess I'm moving to China and try to get a job in that chemical warfare place."

"I hope you succeed. But do you have a way to get there?"

"Possibly by ship."

"Well, I have to get going now. Don't want the alternative of you yelling at me." Goku said nervously.

"Oh yeah. I remember her. Me from another alternative timeline with the Time Agency. The really powerful me."

"That's the one by. Hope to see you again. I know that you're going to see and avoid a younger me."

"True. I hope to see you again too."

Goku left back home.

'Well I better get going to China and then move back to Japan.'

2020:

"Thank god that I stopped that virus from breaking out. So easy to destroy. I better get back to Japan and live out my life. 40 years to humans born with quirks. And 54 years to the younger, Goku appears there."

Goku arrives back home and goes up to a newly built dimension portal machine. That Bulma made.

"Right I have already checked up on Naruto, Luffy, Natsu and Deku are all fine. Now to check on Sonic's." Goku said happily.

"What the fuck!? Dead animals, blood instead of water, along with a dark red sky. What happened? I better close the portal." Goku asked himself while in a shocked panic has he turned off the portal.

"Man, it's a good thing I closed the portal stopping the evil from coming through. I'll go there later on to stop the evil there." Said Goku in a mixed relief serious tone.

'But I might end up needing some help. And I know who to go too.' A hand then touched his shoulder.

"Ahh, evil Nezuko?"

"I wanted to warn, Nezuko Jr. Goku, it is demon called Exetior took Sonic's body and did all that you saw. But he then ditched Sonic's for a new more power body. So are you going to help defeat him?"

"Yeah, but I need to get family member from an alternative time line. Who also works for the time dimensional agency."

"No! You don't mean? The full Saiyan demon hybrid? Hina Son?"

"Yes her, my daughter of another me and an ex upper moon four who never ate humans."

"Well, she is way more powerful than you. But I don't want to fucking die! She is like the strongest out of everybody!" She shouted. "But I guess since who we are going up against is insanely powerful. Even Shadic had failed."

"Shandic failed? Did they die?"

"No, they managed to get away as Sonow their fusion by the dance."

Goku blew a sign of relief. "We better get going."
