15 Death of Muzan

I am now sitting in front of Ubuyashiki Kagaya with a cup of green tea on the table in front of us. And as expected, his voice is very soothing that it made all of my worries disappeared. Is it his innate skill? I do not know. Hinaki and Nichika Ubuyashiki are sitting behind him and tending his necessities.

The two of us are introducing ourselves inside his mansion where he meets Hashira. And Hashira plus Tanjiro are kneeling outside but at a distance where they can hear our talk. Nezuko is sitting behind me as my fiancé. A fiancé can stay in the room when her other half is talking about something important with someone else? I do not know.

"Now, I will tell you the reason I requested to meet you," I told him after putting down the cup I was drinking back to the table.

"I was also surprised. When I heard that a normal person was walking around in onis' feeding ground, I thought I was hearing wrongly," I smile.

"Well, it must be disturbing for you not able to look at another person while talking. So…" The Hashira took offense to what I was saying and tried to stand up but Kagaya stopped them. He must be a very patient man. Being able to control his anger.

Just like that, light shone inside the mansion. And sitting in front of me is a handsome man with black eyes.

"Wow, I must say, without your cursed marks you are pretty handsome!" I gave him a thumb up.

He looks at his hand. Then touch his face where his former cursed marks once were. Tears were streaming down from his eyes. And angry faces from the Hashira are gone and some are now in tears. Look like all of them really love their Oyakata-sama huh?

"Well, let's stop for today. You must be eager to show yourself to your family. I understand. Let's have a meeting tomorrow morning. Is that alright?" I spoke. I told myself that I should not destroy other's happy moments for my own sake. But this does not include my enemies.

"Thank you," he gave me a bow. Not just a simple bow. He stands up and moves himself a little further back. Then sit down once again and gave me a dogeza.

"Thank you. I don't think you will understand how much this means to me. Thank you very much!" Wow, what a great dogeza. And his twin daughters are also behind him doing a dogeza. When I look outside, all the Hashira are doing dogeza too.

I did not expect this. All the Hashira here must respect him to a scary degree. I wish I also have subordinates like them.

"You are welcome," I said. At least I know that if I were to keep denying it, that will be rude of me.

I was given a room in his mansion. I must say it was a very touching scene to see Kagaya doing a group hug with all of his family members. He kept touching his kids' faces now that he can fully see. I could see this man is very proud of his family.

Nezuko was also given a room but she said she wanted to catch up with her brother. And went to Butterfly estate with her brother. I kept wondering why did the trio need to go to the estate even though they are not hurt. But then I remembered Inosuke. I forgot to heal him. I sigh.

Today morning, we are at the same place where we were yesterday. Kagaya and I are sitting face to face with his twin daughter are behind him and Nezuko behind me. Hashira and Tanjiro are outside.

"Well, let's resume what we were talking about yesterday. I can summon Kibutsuji Muzan here for you all if you want me to and made him unable to move nor talk. Well, I can allow him to talk if you want to." I told him with a serious face.

All of their faces looked shocked. Including Nezuko's. Oh, yea. I haven't shown her teleporting, haven't I?

"Can you really do that?" Kagaya asked me. Not that he doesn't trust me but because he was too shocked.

"Yes, I can. But let's test it on some other oni first. Is that okay?" I asked.

"It is okay. But which oni are you going to choose?"

"Hmm… I will choose a Hashira randomly and let him or her choose."

Kagaya nodded at my choice. I did "Eeny, meeny, miny, moe" on Hashira and surprisingly, it stops on Shinobu.

"That person who is always smiling. Come with me for a while," I said.

"Do you need something?"

"Yes. Do you have an oni do you want to kill? Anyone is possible."

Her expression immediately changed. "Anyone?"

"Yes, anyone."

"Then can I ask for an oni with the bloodstain on top of his head? The oni also likes to speak in a gentle manner with a carefree smile."

Some of the Hashira gave her a knowing look. Look like those are the one from the time when her sister was still alive.

"Hmm… the information is a little vague. Any more information?"

"He is the one that killed my sister."

"Say no more. Kagaya-san, can I get a paper?"

It was Shinobu who gave me one.

"I always carry one around with me."

"Then, let me start."

After a while, an answer appeared on the paper.

|Upper Moon Rank 2, Doma|

All the Hashira are surprised but not Shinobu. No ordinary oni can defeat her sister after all.

"Upper Moon 2, correct? Then let me ask you something."

"Yes?"

"Do you want to kill him yourself or kill him by putting him under the sun?"

"I would like to kill him myself."

"Then we would need a place where sunlight cannot reach."

"You can teleport him in this mansion," Kagaya said.

"Oyakata-sama!" Shinobu and other Hashira tried to protest.

"It's okay. If what he said is true, we don't need to use this mansion anymore because you all will go on a different way."

"Does that mean?" Rengoku exclaimed.

"Yes, Demon Slaying Corp will be disbanded after the defeat of Kibutsuji Muzan."

"Well, I will be teleporting him here now."

And in front of me is a man with pale golden blond hair laying on the floor lazily.

"Hmm? Where am I? A man? I am not interested in a man. If possible, bring me women."

This got a reaction out of him. He tried moving and talking, which is futile. I see he is trying to call out ice.

Ice that was already formed turned into ice dust. Now, he cannot use his 'Blood Demon Art'.

"The same, dude. I am not interested in men. Now, the floor is yours." I gave a welcome bow to Shinobu. She looks absolutely livid when she saw Doma. A smile that is always on her face is nowhere to be seen.

"You are the one that killed my sister!" She walks slowly toward him.

She stabbed him with her sword. Doma got poisoned but he easily neutralized it. Shinobu got a heyday using all of the poison she got. But no matter what she used, Doma quickly neutralized. None of the poison she has can kill Doma. They can weaken him but cannot kill him.

It seems Shinobu lost her patience. She grabbed Doma and lifted him over her head like lifting a dumbbell. Then proceed to throw him outside under the sun. Poor Doma can't even scream because I forbid him to open his mouth.

"Phew, that lifts everything in my heart." She then turns toward me, "Thank you very much for letting me take my revenge. You can ask me anything you want. I will do everything I can do for you," and gave me a 90-degree bow.

"Sure. Can I ask one now? Is it possible for me to have your research on poison and antidote? And some medical scrolls if possible."

"It's okay. I will make sure to prepare when everything is finished."

"Thank you."

I turn toward Kagaya. He couldn't hide the excitement in his eyes and gave me a nod.

In front of me is a Michael Jackson rip-off standing while his hands are in the pocket.

I added any way is a precaution for telepathy. I don't know if he can use one or not. But better safe than sorry.

"Muzan, after all these years, I got to see you fall." Kagaya came and stand beside me.

"Well, you Hashira can rain him down with your rage. I made sure the mansion can withstand your rage," I said.

And Hashira did not shy away. One by one, they used all of their moves in their breathing style. Muzan kept healing even after tanking all of those moves. And seeing all of those wonderful moves is a plus for me.

After all of Hashira finished, it was Tanjiro's turn. Beside him, Nezuko gently holds his hand. They are now seeing face to face with the man who killed their family after all.

"Tanjiro!" I shouted.

"Yes, Hiroto-kun?" he replied back.

"Use the 13th form of your 'Dance of the Fire God'."

"Eh? 13th form? There is no 13th form."

"Yes, you do. It is basically continuously performing all twelve forms of the moves in repetitive succession to increase the accuracy and agility of your movements while reducing fatigue."

"Eh? Is that so?"

"Yes, after all, the real name of your dance is 'Breathing of the Sun'."

All people inside aside Nezuko quickly turn their heads toward Tanjiro.

Tanjiro looks determined. He is now standing in front of Muzan and proceeds to dance his sword art.

This form was created solely for the purpose of killing Muzan since the repetition of all twelve forms aims to destroy Muzan's twelve vital organs that move freely inside his body thanks to his shape-shifting ability.

After all the organs being destroyed, Muzan quickly turned into dust. We made sure to put them all into the sun just to make sure.

All of the people here are celebrating.

[Mission 2 finished.]

I heard a notification from the System. I now remembered to learn a Breathing Style. I turned toward Kagaya and asked, "Sorry to interrupt but can you tell me is there a Breathing Form that uses this kind of sword?" I proceed to take out <Night Sky Sword> out of the bag which is actually from the <Inventory>.

"Western sword, correct? Then there might be one. It was from Tsugikuni Yoriichi's era. Let me get it for you," then he went to the bookshelf in the room. Wow, talk about security.

When I saw the book cover, it is named "Breathing of the Darkness". Sound ominous.

"The swordman had no successor and he only wrote his experience in the book. You can take it if you want. I am going to burn all the books now that demons are gone."

I nodded at him. When I look inside, there are 6 styles. Well, time for me to learn these.

The Demon Slaying Corp celebrated this for a week. Then, time for me to train. They let me use their place to train.

Then, 2 years had passed. I had finally finished learning all the forms in this breathing style. Nezuko and I got married during these 2 years. And Tanjiro also got married to Kanao. Demon Slaying Corps also got disbanded. Shinobu and Giyu got married and opened a flower shop. Zenitsu, surprisingly, got married to a girl too. I don't remember her name.

[Mission 1 finished. Host will be returning to his homeworld. Time in this world will be stopped.]

{System, can I really not bring Nezuko?}

[That is correct, host. Even if you bring her right now, she would be sent to jail for marrying an eight years old kid when you get back to your world.]

{I will be able to bring her back on my 15th birthday, right?}

[That is correct, host. Will you be going back now?]

{Yes, I won't be able to make up my mind if I say goodbye to her.}

[Returning host to his world.]

[Success]

I am now back in my study room. But more importantly, I must ask System a question.

{What the hell, System! Why the hell did my personality change!}
