Male OC X Kimetsu No Yaiba / Demon Slayer

Obanai Iguro

I'm sweeping the yard as usual. Ruka is pregnant and Shinjuro went for a mission. Kyojuro and I do our best to divide our time to take care of our mother and our house. Not to forget that we still had the training to do. "Fuh... I'm done. Now, it's training time." I raise my wooden sword and Kyojuro suddenly screams with anger.

"ONIICHAN! How dare you start without me!"

"Ah... sorry..." I pat Kyojuro's head to make him feel better. " Let's train together."

"You think I'll forgive you that easily?!!"

"Fine. What should I do as an apology? Jump from a cliff?" I tease him.

"ONIICHAN!"

"I'm just teasing you." His reaction is so amusing.

"Hmph! I want you to sing another type of song! You only sing sad ones! I want something else!"

Oh, so he dislikes my taste hmm? "Okay, I'll sing after our training."

"Promise?"

I ruffle his hair. "Since when I broke any promises?"

Kyojuro laughs gleefully. "Okay oniichan!"

"Phew... I'm done. How about you otouto?"

"Hmph! I'm done too oniichan!"

"Well done my sons! You don't slack off even when I'm away!" 

We turned our heads and there stood our father and a small black-haired boy with his mouth covered with bandages. He has a white snake on his shoulder. Kyojuro seems excited while I'm actually feeling nervous. Sigh... my poker face always hides my emotion.

"Father!" Kyojuro runs towards Shinjuro and hugs his legs. "Hmm?~ Father! Who is this?" Kyojuro asks Shinjuro with sparkles around his eyes.

"This boy is Obanai Iguro. He will stay with us from now on. Treat him nicely, okay?"

Obanai Iguro... the future serpent pillar... is staying with us...*chills*

Wait! No no no... don't think about him like that! Right now, he's a child who wants to survive in this cruel world. Sigh... my future is sure full of surprises. I wonder what's next?

"I...I can't accept your kindness, sir." Obanai lowers his head and tries to hold his teary eyes.

I run towards him and hug him. "It's okay. You're safe now." I whisper to his ear. The snake, Kaburamaru wants me to stroke him so I do it. Kaburamaru seems to enjoy it. Obanai seems in shock that I'm not afraid of him or his pet snake. His tears start to fall and he returns my hug and cries. "Stay with us. Let's get stronger so we can save humanity from demons by becoming a demon slayer." I whisper words of encouragement to him.

Obanai seems snapped. After a long silence, he finally reply, "Okay, I accept your offer."

I pat his head gently. Sigh... it must be hard for him. Being chased by a snake demon and his terrible family issue. They make him a sacrifice. What kind of family are they?!! Shinjuro must have saved him from the demon. I must hide the fact that I know a lot of things. Think about another topic!

Wait... kind of to think of it... "Dad, can we have our own pets too?" I turn my head to my father.

"No! Kaburamaru is an exception because it will never leave Iguro's side!"

Sigh... there goes my chance. The real reason why Kyojuro and I were never allowed to have a pet is that Shinjuro hated animals. "Father, the mother is inside. Can we go to the nearby lake?"

"Sure! You know the rules! Return before sunset!"

"Yes, father..."

"ONIICHAN! Let's go!" Kyojuro holds my right hand while I hold Obanai's hand with my left hand.

We seat at our usual spot and I breathe in the fresh air. The gentle breeze somehow calming... until...

"ONIICHAN! Don't space out! You promised to sing!" Kyojuro jolts me back to reality.

"Ahh... sorry."

"You can sing? Can I hear it too?" Obanai asks me.

"Sure. But with one condition." I use my pointer finger to point directly towards his face.

"Huh?" Obanai is confused right now.

Before he misunderstands anything, I continue, "Yes. You must call me Yoru and my twin here is Kyojuro. In return, we should call you Obanai."

I can tell that he's smiling sincerely under those bandages. His heterochromatic eyes also soften. "I accept your condition, Yoru."

"Oniichan~ Hurry up! We can't wait to hear you sing! Right Obanai-Kun?"

Obanai nods his head eagerly. Sigh... I can't let them down, can I? Obanai needs something to lift his spirits. So I guess I'm gonna choose 'Not Today' by BTS. I close my eyes so my poker face doesn't look weird when I'm singing this song. Oh! And I should change 'Bangtan' to slayers because it's more appropriate.

Fuh... I finished singing that song. That was tiring. When I open my eyes, I was greeted by the sight of their sparkling eyes of admiration. Argh... so bright... wait... KABURAMARU TOO?!! This is... unexpected.

"WOAH! ONIICHAN! THAT SONG WAS AMAZING! You actually can sing something else than heartbroken songs!" Kyojuro compliments me.

"Huh? He sang heartbroken songs before?" Obanai asks Kyojuro.

"Yeah! Those songs can make me cry! Oniichan is a heart throbber!"

"Hey, do you realise that I'm sitting right next to you?"

"Hmph!"

Sigh... so he's mad at me because I made him cry? Meh. I don't care. Those songs are beautiful.

"Let's go home, otouto, Obanai-kun." I stand up and offer them my hands. They both accept it without hesitation and we're going home together with cheerful vibe around us.

What a good day. I can't wait for tommorow!
