Demon Slayer: I Got Reincarnated As Yoriichi

The next day.

A boy with different eye colors arrives at the training ground. Chikafusa and Ai weren't there like they used to be.

"They haven't arrived yet, have they? I see, they're still thinking about Hajime. I guess I have no choice but to train alone."

He continues his training without his companions. "It's a pain in the ass without anyone. Not even Yoshimitsu is here, I doubt if he is on a mission."

Suddenly…

He hears a feminine voice from behind, "Hey! You're training on your own, without anyone?"

The girl with a voluptuous figure, big breasts, and curly pink hair approaches the boy.

The boy blushes a bit at her moving breasts and looks away like he hasn't seen anything, "Oh, Kumayami Rinka!"

"Are you training without anyone?" the girl asked.

"Yes, I am training all on my own. How can I help you?"

The girl softly giggles and says, "You're so sweet one, but I am not here for any help. I was just roaming around and found you training alone."

"This girl talks so much..." He thinks.

"I just can't miss my training session. I can understand why Hanako and Yamamoto haven't arrived for the training. But honestly, I recommend them to move on. However, I can never understand their pain." he says.

"They're devastated by Hajime-San's death. They couldn't accept his death and decided to find him even if the chances were one in a million. I couldn't help but cry myself too." says Rinko.

Rinko looks at the boy's unusual eyes with curiosity. "You've got such beautiful eyes. But why do you always cover your lower face with bandages?"

The boy replies without looking at her, "Kumayami-San, I just can't tell you."

She smiles and says, "Okie! I won't bother you."

He takes a sigh of relief and says, "I'm glad you understand."

"Also, thank you for not hitting me in our duel. I was scared of you, yet showed mercy upon me."

He ignores her...

"And if you don't mind, what's your name? You always seem mysterious to others and nobody knows your real name. They refer to you as "Nameless-kun"."

The boy stays silent at her question. After staring at each other for a long, he breaks the silence and says, "I don't remember if I have any name. I haven't given any name since I was born. Like everyone, you can call me "Nameless" as well."

Rinko's expression turned sad as she heard his response, "No name? You're nameless? How?! Tell me why didn't you get any name?"

"It's a long story."

"A long story? I'd like to hear it."

The boy's eyes widened again at her response, "But why are you so eager to listen to my story? Trust me, it's nothing more than a time waste and pain."

"I don't care if it's a time waste or not. I only know that it's important to you."

Nameless takes his step back. He doesn't understand why she is so curious about his story.

.

"I already warned you. If you still wanna listen to my story then I won't stop you."

*Sigh*

"Are you ready? I am warning you again, it's a very long story."

"I am ready!" she exclaimed.

As he begins to speak, he inhales deeply and vividly recounts his tale. A brisk wind picks up, tousling his long, black hair.

"Alright!

15 years ago.

I came into existence as part of a financially prosperous family... but gained its wealth through illegal and ruthless means.

They adhered to a belief in the twelve demons of fate, entities with the power to grant immeasurable riches in exchange for a sacrifice.

Tragically, the sacrifice they offered was none other than their own firstborn child, a heinous act committed solely for the pursuit of wealth.

They were the twelve colossal demons, towering at the height of the tree. My family served them for more than two generations.

I was born as the first child in a cruel family. When I was just a child, the family decided to offer me as a sacrifice to the demons. However, upon seeing me, the demons were astonished by my appearance.

I had an otherworldly pallor, and my eyes were a strange sight to behold one blue and the other a vivid yellow, although my right yellow eye was barely functional.

The demons saw me as a divine blessing and planned to consume my flesh only if I grew up. Being a child wouldn't give them proper flesh of mine.

So then, the demons warned my family to keep me away from the outside world and they agreed to do so. I was isolated in a sealed room away from everything. I spent my entire childhood confined in that room. I wasn't even allowed to go outside. I wasn't even given a proper education.

It was my biggest nightmare. I was terrified of being alone. I wanted to live properly like everyone else. No matter how much I cried or begged them, nobody heard my request.

I had no family members, and no friends to play with. My life was a mere suffering.

.

My life was depressed and painful until I met a young girl around my age. She was meant to serve me.

Like me, she was also destined to be devoured by the demons when she grew up.

They didn't only ruin my life but also hers. Turning a young girl who is unaware of the world into a servant meant to serve me.

Her appearance was just as unique as mine. She was an albino with striking red eyes and long white hair. She was an extremely innocent girl. Her name was Miko.

She was the only one who could talk to me. The only one who was worried about me. The only one who was precious to me.

She was like my only sibling. My little sister.

She would often say "Onii-Sama, are you alright?", "Onii-Sama! Don't worry, everything will be fine!" and so on.

I promised to show her the outside world and take revenge on the demons.

.

However, I asked her so many times about my identity. This question always haunts me till now...

"Who am I?"

"What's my name?"

"Why am I so incomplete? Why was I even born?"

She never cleared my doubts. She always stayed silent in the response. But I could see concern for me in her eyes.

I don't know my mother, I don't know my father, I don't know my siblings, I don't know my family, I didn't know anyone. The only person I truly knew about was Miko.

For the sake of her life, I decided to vanquish all twelve demons and give her a glimpse of the outside world for the first time.

At last, the moment arrived when I could exact vengeance upon the demons.

At the age of 12, I was chosen to be sacrificed to the demons."

3 years ago.

At night.

Amid the dark forest, Nameless confronts the twelve colossal demons.

"How am I supposed to fight them back? They'll crush me in no time."

The demons' crimson eyes glow in the darkness giving him an eerie vibe. A death stare at their eyes trembled the entire body of him.

Suddenly, he hears footsteps coming from behind. As he turns around, he sees Miko approaching the demons.

"Miko?! Why did you come here?"

Miko stays silent, her face turns serious as she is about to be devoured by the demons.

As she begins to speak, her tone changes to serious, "Onii-Sama, don't you know why we are here? We're about to die!"

His eyes widened at her response. He has never seen her acting like this before, "We are... About to die? No! I won't let you die here! Just run away from here! I promised to keep you safe! I promised to show you the outside world! You can't die here! I am here to—"

She interrupts his words and says, "Onii-Sama, what are you saying? I won't leave you alone. I don't wanna live in this world without you. You're... You're my big brother..."

Tears streamed down her face as she finished her words. She furiously glares at the demons despite the tears flowing through her eyes.

"MIKO—"

.

She looks at him with a warm smile on her face. "Onii-Sama, this is not our end. Do you remember when you promised me to kill the colossal demons?"

"Yes, I remember it. But why are you mentioning it?"

She softly giggles and says, "Don't you wanna fulfill it now?"

She takes out a sword concealed in her clothes and hands it to him. "Onii-Sama, take this. Now we can fight together."

"A sword? Where did you get this from? Oh, never mind! You're right, now we can end this battle forever."

He thinks, "Is it okay to fight these giant demons? I've never fought in my lifetime. But I have to do this to save Miko. No matter even if it takes my own life."

Miko holds another sword and approaches one of the twelve demons. The demon is about twelve times bigger than her.

"Oh, the twelve demons of fate! I am ready to be devoured. May you show mercy upon me and enlighten me!" says Miko.

The demon reached out to grab her, but she agilely leaped onto its outstretched hand and launched herself towards its menacing head. With a swift and decisive motion, she severed the demon's head from its body.

"How?! I never thought she could be so powerful." he thinks.

She looks at him again and says, "Onii-Sama, won't you help me this time, will you?"

"Ah, Alright!"

The remaining eleven demons scream wrathfully. "OH, YOU PITIFUL KIDS. WHAT HAVE YOU DONE? YOU'VE KILLED OUR BROTHER! NOW YOU'LL PAY!!!"

They burn the forest around them. They come together and chant, "OH, HOLY LADY! THESE PITIFUL KIDS DISOBEYED US! THEY'VE KILLED OUR BROTHER! NOW YOU SHALL SHOW YOUR WRATH! KILL THEIR FAMILY! KILL THEM!"

Suddenly, his family runs towards the demons and bows down. "Oh no! We're terribly sorry. It's this servant girl who killed your brother, not us. Please forgive us!"

Suddenly, the family members collapsed on the ground. They're bleeding from their mouth and nose.

"What?! How did they die? The demons didn't even move a bit to kill them. So how is this possible?!"

The demons glare at the boy and say, "YOU'RE LUCKY TO NOT HAVE HER EFFECT!"

The boy ignores them and lounges at them. He and Miko easily dodged all of their attacks and struck them with their swords. They engaged in a fierce battle.

"For the first time, I am moving my body so much. I don't know how we are able to keep up with these demons. Our movements are similar to that of the serpent's."

During the battle, they both managed to slay every colossal demon except the last one. They are exhausted and Miko is in a severe condition. She is bleeding from her head and her stomach has been damaged.

"Miko, are you alright?! We need to retreat. You're bleeding! Look at your head!"

"I am fine, brother. I just can't fight anymore. Please kill the last remaining demon. Please avenge me."

"Alright! But after defeating it, I will take you away from this place. We will retreat without any second thought."

He lunges at the last demon and engages in a fight. For a long time, they fought equally. The boy eventually finds an opening to behead the demon. With a surge of unstoppable force, he delivers a decisive blow, ending the relentless struggle by beheading the demon.

"Finally! The fight is over! My revenge is done, Miko."

When he looks around, he finds her lying down on the ground. Her head has been bleeding so much and she is in a critical condition. The fire has also spread over her body.

"MIKO!!!" he screams and runs towards her.

"Miko, why didn't you tell me about your condition? I thought you were fine."

He extinguishes the fire on her body and puts her on his shoulders. He runs towards the town for help.

"Onii-Sama... Thank you... For avenging me..."

"Miko, I'm glad you're still alive. Don't worry, your brother won't let you hurt. Nothing can take you away from me."

"Onii-Sama... I'm glad to have a brother like you. But I'm sorry... I... I can't live anymore..."

"Miko, stop talking nonsense. Please don't talk! You're just hurting yourself!"

Miko smiles and says in a calm and soft voice, "I'm sorry... I can't live anymore... My time is near... I am not afraid of dying... Because... I have you..."

Tears streamed down his cheeks and his body trembled. "Miko, don't speak nonsense. How am I supposed to live without you? It's my order that you won't leave me. You've never disobeyed my orders. Don't worry, all is well."

.

"I apologize... Onii-Sama... Farewell~"

Suddenly, her body stops moving and she immediately becomes colder. Her eyes are closed and she isn't breathing anymore.

.

"Miko!"

"Miko!!! Why did you stop moving? Are you alright?"

She doesn't respond.

He puts her body on the ground and caresses her forehead. "MIKO... You can't leave me alone... Please, don't leave me."

He starts crying loudly and blaming the cruel fate.

"MIKO!!! Please don't leave me alone. Please wake up!!! You can't die."

"MIKO!!!"

———————————————————————

"Since that day, I couldn't move on from her memory. I still have her soul with me. She is within my heart.

She was the only one who knew about me. But she didn't tell me my real name. Even though she didn't know my real name...

Because my name never existed...

I am... the nameless being..."

*Phew*

"I already warned you that my story is long."

He looks at her face and finds that her eyes are filled with tears.

"Huh?! Are you crying? Just for me? Why?!"
