Truth [DS Fanfic] Tanjiro×Muzan

Chapter 3.1 Tanjiro's Yushi

1912

Back in those olden days, when Tanjiro was still just an innocent slayer. Who would have thought that the future DSC would become this corrupted? He settles in from Tamayo and Yushiro with his short light bluish-green hair. They chat as per usual as Nezuko who is a demon, just running around with bamboo in her mouth. "Haha...Nezuko, she is very cute." Tanjiro commented to which Tamayo giggles a little before saying "She is indeed a child at heart. I would like for her to stay with us for a while if you wouldn't mind."  Tanjiro nods, to which Yushiro reacted heavily "What is this?! Her? With us?! NO! She is an outsider! We shouldn't trust her!" 

"AN OUTSIDER?! SHE IS MY SISTER!" Tanjiro yells. The two are huff puffing in anger at each other as Tamayo watches with a little sweat on her forehead. "Will you two stop it?" Tamayo asked in an polite but aggressive tone and of cause, ending off with a smile. Tanjiro looks away, "I have an errand that I would like to run. I will then excuse myself for a moment. Why not you two and Nezuko of cause, have a little small chat?" Tamayo said as she hurries out of the room. Silence. How awkward. "Haha..Nezuko, you are bored isn't it?" Tanjiro talks to Nezuko as Yushiro looks away. "Let's go walk around in the jungle eh?" Tanjiro asked, to which Nezuko nods. They head to door as Yushiro continues to sit still. Tanjiro stops and turns to Yushiro...Looks like he is sulking haha. "Yushiro? Do you want to come along?" Tanjiro called. Yushiro doesn't react. "Yushi?" Tanjiro called his name like this. Yushiro immediately react "YushiRO! My name is YUSHIRO!" Tanjiro smiles. They exit the place and walk about in the Jungle protected and masked by those sigils that would fend off other demons. 

As Nezuko sped off, Tanjiro and Yushiro walks slowly down the jungle. "How did you...Became a demon?" Tanjiro asked. Yushiro didn't answer for a moment, processing whatever he says and then when he is ready to reply, he did "I was...Sick...I was very sick...She gave me a new life. Something that I am grateful for having." Tanjiro sighs as he replies "Nezuko once caught on to an illness that was hard to be treated, but eventually as time went by, she gotten better...It was a blessing." Tanjiro said it with happiness. "I can't live without her." He adds. 

"So as I, I can't live without Tamayo. She saved my life." Yushiro states. They continue to walk through the jungle following Nezuko. Then....Boom.....Booom....BOOOOMMMM! The sigil that is protecting them! It's broken. Demons starts to enter the realm. Tanjiro grabs his sword, "Neuzko! Retreat!" Tanjiro commanded. They prepare themselves. As demons rushes towards them, Tanjiro slash them with his sword, using breathing techniques to fend off the house. Yushiro on the other hand uses his blood demon arts to mind control other demons to attack each other. Nezuko is there, kicking and destroying demons. 

The demons keeps coming, again and again. "Why are they even here?!"Yushiro asked. Something unexpected happened. A demon fires an explosive towards Yushiro, Tanjiro saw it. He rushes towards the explosive. "Don't do it baka!" Yushiro yells, but it's too late! Tanjiro uses his breathing techqiue and manages to explode the explosive directly on the other demons, but in return, Tanjiro himself gets injured. He lands on the ground, with his sword pierced through the ground, acting as a support. Panting. Yushiro rushes over to Tanjiro, "Nezuko! Let's go!" Yushiro yells. They disappeared. 

Reappearing in Tamayo's safe house. Yushiro lay the injured Tanjiro on the ground, he goes through the medical box for herds that could help Tanjiro. Nezuko siting in the other room with Tamayo at her side. Yushiro place some herbs on the wounds. Tanjiro twitch in pain.  "Why did you do that?" Yushiro asked, mixing another mixture of herbs. "You're a human, you can die." Yushiro exclaimed. Tanjiro softly open his eyes a little and weakly says "Because...I deem you...as a friend...Thank you...for taking care of Nezuko." He lay his hand on Yushiro's thigh. Tanjiro smiles. Yushiro looks at Tanjiro's hands and held it.

As time goes by, they became best of friends and undeniable bond is built with each other....Often Nezuko would play outside, while the two of them wathces Nezuko play. One night, after Tanjiro and Nezuko decides to go out and play, Tanjiro got really tired...Even though he is young...but he is a human after all..Humans can't withstand long hours of playing. He staggers tiredly to the house. He crash on to the ground, his head is facing the ceiling. Panting. He closes his eyes, resting...When he opens his eyes, he noticed Yushiro's face. "AHHHHH!!!!" Tanjiro screams, he sits up in shock. Yushiro laughs. "You must see your own face when you are shocked. It's pretty hilarious." Yushiro commented. 

Tanjiro pushes Yushiro as he laughs, they are so bubbly together. An arm's length apart. Then the laughter subsides., Tanjiro grins. "You know...thank you...both...Tamayo and You..for treating Nezuko and I like a family...I can't imagine that someone would accept us." Tanjiro states. Yushiro replies "Of cause, it's alright. We are medical practitioners who takes great care of people...So it doesn't really affect me much to bring in someone who is in need." Tanjiro nods as he says "You know...sometimes I wonder why you are especially so kind to me...Is it because Nezuko and I are the first one whom you two gratefully brought in?" Yushiro looks away. He sighs. 

"You are quite special. Tanjiro. Something about you really strikes me...You are someone that would take care of Nezuko despite her being a demon My family..when they knew that I was a demon...They kicked me out and broke ties with me. It was a sad ending." Yushiro said. Tanjiro grins and playfully says "So you treat me like a family? Haha. It is nice to be apart of this family. You can be my older brother!" Yushiro laughs as he replies "NO! Older brother?! Younger Brother! I look younger than you!" They laugh at each other breaking the sadness as they fight to see who would be the young brother. As they tussle, Yushiro's face got a little too close to Tanjiro. They went silent. As they look at each other, something feels different and It feels like there is some desirable words that Yushiro wants to say. 

"I....like you..." Yushiro exclaimed. Tanjiro froze, Yushiro makes his first move by moving forward, kissing Tanjiro softly on the lips. A light peck. Then again. Another peck...as for the third peck, their pecking turns full blown kissing. Yushiro's kiss was so strong that he pushes Tanjiro's down to the ground. They kisses slowly. "Stop stop." Tanjiro said. Tanjiro rolls to the side... "Sorry...I-" Yushiro goes behind Tanjiro, he grabs hold of Tanjiro's mouth, covering him, as he hangs his free hand on to Tanjiro's crotch. Groping it lightly as Tanjiro moans.

(Writer:Reader...Anything familiar?👀 Ah? haha)

"Just....Let me have you...."

Who knew...100 of years later, they meet again and Tanjiro is doing it to Yushiro. The one who initiated the relationship became the opposite.
