#yoshiteru

ohhh it took me a sec to remember what u were referring to, but ur talking abt this post arent u.

interesting concept anon, interesting. heres my interpretation of how things might play out :]

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

toko and yoshiteru come across a perfectly normal totally human person <3. and they act very normal abt it

Ahhhh, what a awesome and interesting ask! Well, I don’t really argue with close-minded people about something, so if they still want to be stubborn and still want to think it’s incest, best thing is to leave them be, because we know it’s not incest and Gotouge already explained it, their fault they’re stubborn not anyone else’s. 

Anyways to the ask! Without an illustration since there aren’t GIF’s or pictures:

PS: Time-travel doesn’t seem realistic to me, so excuse me if I took it into my comfort zone, I had a better idea for it!

Sumihiko and his brother were having a sleepover over the Agatsuma’s, Kanata mostly by Touko’s side, holding her hand and both smiling to one another. Sumihiko and Yoshiteru talking about anything really.

Their conversation went on, until Sumihiko brought up the story of their ancestors and how they fought with the demons and the Demon King.

Touko listened to their conversation and rolled her eyes, stating that it was just fiction, that their great-grandpa was just someone with big imagination. Upong which Yoshiteru argued her statement, earning a harsh pull on the ear.

“What if they actually existed and fought against them? Can you prove it’s fiction?”

At Sumihiko’s answer, Touko had much hesitation, she herself didn’t have any proof to her statement. So she just said she didn’t.

“What if we time-travel?”

*Of course Yoshiteru was greeted by his oldest sister’s scolding and ear pulling.

“You dummy! Time-travel doesn’t even exist! Why is it that you’re like this always! Was great-grandpa Zenitsu like this?!”

“Of course time-travel is impossible... But if they existed, then surely some memory or something may be there.” Kanata tried to reason and calm Touko down, so she could stop pulling on poor Yoshiteru’s ear, which was pretty swollen and red.

Touko stopped doing what she’s doing, smiling and giving the reason to Kanata. That boy surely made her relax a little.

“Well, great-grandpa Tanjirou fought with this katana right?” It was when Sumihiko pulled out the katana they kept as memory.

Kanata wasn’t that happy his younger brother took the memorial katana without asking.

“Sumihiko, you shouldn’t have taken it. It’s a memorial.”

“I know, I know, but I’m curious about great-grandpa and his adventures with the demon slaying job! How he and great-great-great Aunt Nezuko had it. We know the story of our three-times great uncles and aunt dying and our three-times great aunt turned into a demon, how they went throught it, so many things I want to know!”

Sumihiko’s enthusiasm was evident, and it all started to get Touko more interested in the topic. Well if they really did existed, then maybe there is something somewhere to know about them.

The four talked about the topic until pretty late, and called it a night, everyone sleeping in futons in the living room. Soon, they all started to dream. It was a shared dream. In the dream, Sumihiko woke by started, he was in a different house, didn’t seem to be Touko and Yoshiteru’s. It all looked pretty ancient, like the Taisho era.

“Eh? Where are we?” The boy looked around, and felt pretty out of place and worked out, he noticed his brother was sleeping next to him and shook him lightly. “Kanata, Kanata! Nii-san wake! We’re not in home!”

Kanata groaned and slowly opened his eyes. “Sumihiko? What are you saying-” He was quick to sit up, his brother was right, that wasn’t  home. He quickly turned to Touko sleeping by his other side and shook her. “Touko? Touko-chan, wake up, something’s up.

Touko was quick to be up and smacked her brother awake. “Wake you you dummy!”

Yoshiteru yelped and scrambled to his feet. “Wha, nani nani?!”

“We’re not home, where is here?!” Touko was becoming pretty agitated, when Kanata held her hand and she calmed almost immediately.

“Don’t worry Touko-chan, if you’re here with me, then nothing can happen to you.” He reassured her softly.

It was night in that strange place. Soon they heard some voices, turning looking in awe.

“Tanjirou! Where are we going?!” A blond with the same appearance as Yoshiteru but save from the blond to orange hair.

Then the called boy stood there, it was Tanjirou, Kanata and Sumihiko’s great-grandfather, very alike with Sumihiko, save from the earrings and the scar.

“Great-grandpa Zenitsu...” Touko whispered

“And great-grandpa Tanjirou...” Sumihiko echoed.

“It was real after all...” Touko was no convinced and Yoshiteru took advantage of it.

“I was right all this time, not Nee-san?”

“Urusai, baka!” Touko kicked him in the side, she had such a temper, once again she found herself being held by the hand by Kanata and she calmed.

“I wonder why my sister is such a hooligan...” Yoshiteru grumbled, but then quickly shut up at the glare said sister shot him.

Soon it came the time where Nezuko pulled out of the box and stood next to her brother. Many similarities with Touko. The other girl at seeing her three times-great aunt, she got a real shock, she was demon. All the stories told by their other family members were right and the diary her great-grandpa wrote also was right, she could tell that this was a time where they still were not close to defeat the threat that was Muzan.

“Woah, that kid Giichi’s ancestor” Sumihiko commented, meaning Giyuu who was with the trio, same hair but longer, same deep blue eyes and face shape. Giichi was an elementary kid he often ran into when he was in a hurry to his school, he was watching the ancestor of that kid.

Suddenly Yoshiteru had parted from the group and it was only by Touko who freaked out.

“Ah, where did that idiot go?! Yoshiteru!!” She barked, searching around, they were in an unknown territory but that kid really had to disappear just like that?

Kanata put an arm around her. “Don’t worry Tou-chan, we’ll find him, that’s for sure,” Though he really was in the same with his girlfriend of wanting to smack that kid good.

Yoshiteru had adventured himself a little in the dense forest, wanting to see a demon or see if one would come. He was curious. And his urges to do so came when out of nowhere one jumped at him. The boy screeched. “GYAAAAAAAAAAAAAAAAAAAH!”

“Oh no that idiot got into trouble!” Touko ran where she heard her brother’s scream, going along with Kanata and Sumihiko. When they got there, they froze seeing it was a demon.

Soon a voice was heard. “Water Breathing, Second Form: Water Wheel!”

The demon’s head was sliced off, and Yoshiteru turned to look at his savior, Tanjirou stood there, going over to see if the boy was okay.

“Are you okay?”

“Yoshiteru!!” Touko ran over and immediately smached her brother upside the head. “Baka! Only you would think on getting lost and into trouble in unknown territory, you idiot!” She smacked him again, having half the mind to just smack his tush for that, but restrained herself.

“I-I’m sorry Onee-san...I was scared!” he immediately started screeching with tears, but this time his sister sighed and hugged him. She turned to look at Tanjirou... her three-times-great uncle...

Tanjirou blinked. “H-hey, you kid... you look like Zenitsu..” He stared at Yoshiteru then to Touko. “You like Nezuko...” And then was Kanata. “And you like Kanao....” what got him into a freeze was Sumihiko who looked like him, saved from the earrings and the scar.

“Tanjirou, what’s wrong?” Giyuu soon joined and so did Zenitsu and Inosuke.

The four kids from many, many, many years later where stared at like they were aliens.

“G-great-grandpa...” Sumihiko started.

“Great-grandpa?” Tanjirou blinked, was this some sort of dream? Was he asleep and dreaming that he had a great-grandson? Where were his kids and grandkids then? If this kid was his great-grand son? He didn’t understand.

After a big explanation, Tanjirou understood, in the future he was to marry Kanao, have kids and grandkids, these two Sumihiko and Kanata were his last generations, therefore in the time where these kids were from, he and the others were likely dead.

“This is unbelievable but, here you are.” 

“You were awesome, great-grandpa, really awesome!” Sumihiko exclaimed happily. “You fought with everything and the others too. I’m glad I was able to meet you, something that I thought impossible.”

Soon, back to the current time, the four were starting to wake.

“Uh what?” Sumihiko looked around, they were back at the Agatsuma’s home, so all that was just a dream?

Kanata rubbed his eyes and looked around, unsure of what just happened a while back.

Touko yawned and blinked. “A dream?”

Yoshiteru was simply sleeping soundly still.

“That dream felt very real.” Kanata commented. “So it might’ve been a clue to the mystery of our ancestors.

“Still awesome we got to talk to them even if a dream, that’s checked outta the bucket list!” Sumihiko chirped.

Touko smiled. “Great-grandpa Zenitsu, simply like Yoshiteru, a cowardly yet heroic and strong man. Not that Yoshiteru is that, but our great-grandpa was.”

“Now we now they existed, the heroes.”
