There is an awkward silence on our way back. For me, having a fiancé is the first time in both lives. Although Elle and I were together for a long time, we were yet to engage before I died. So, I don't know what to do when I got a fiancé.

"I am sorry, Nezuko. I don't have any idea how to act as a fiancé. So, please forgive me if I somehow don't know how to talk with you," I said.

"En," was all she replied. But she quietly comes beside me and walks side by side with me.

But then, I felt my finger ticklish. When I look down, I see Nezuko trying to lock fingers with me. Oh, Nezuko. Trying to hold hands? How lewd.

I said nothing and hold her hand. She is blushing heavily and her eyes are looking at the ground. Well, just like that the two of us came back to the inn hand by hand.

The next day we went out to look around the city, it is not like before we went out. This time, we are looking like a couple. So, we did many things we didn't do during our time before. On our 15th day, the Demon Slayer trio came to our inn.

"Hiroto-kun! Nezuko! We are here!" I heard Tanjiro's voice coming from outside.

I pushed my head out the window. "We are coming!"

When Tanjiro saw Nezuko, he looks in awe at her new looks.

"Wah! Nezuko, you look more beautiful! As expected of my sister," he looks satisfied with her new looks.

Nezuko is wearing navy blue color kimono with pale blue color wave patterns with a flower-patterned pale-yellow color with grey threaded hanhaba obi, with another band of blue above it. But the strange thing is that she is still wearing tabi socks wrapped with thick pieces of black material. When I asked her, she replied that it is for long-distance walking.

Her hair is now straight and lost the vermilion color at the tip which she made me use my . She pulls back all the hair that is on the face and ties those together tied with a large navy-blue ribbon at the back of her head. When I asked her why is she wearing nearly all blue, she replied that it was because I like blue. Which is true. Although I wear all white, the color I love is blue.

Zenitsu, like usual, is cursing me for having such a cute fiancé. Inosuke is eager to go for the next mission.

"I am sorry for making you come with us, Hiroto-kun. Nezuko doesn't want to be left out and she wants you to follow as well," Tanjiro apologized.

"It's okay, Tanjiro. Where are we going now?" We are on the road toward Mt. Natagumo, I know. I need to ask him to make sure.

"We are going toward Mt. Natagumo. It is said that onis are seen there." The same as canon, good.

"Well, I have nothing to do anyway. And my intuition is telling me that traveling with you guys will make the trip interesting," I gave them a smile.

"Hiroto-kun," Tanjiro looked moved. Dude, I am not gei okay?

"Hiroto-kun is only talking with big brother," Nezuko pouts.

We got to the base of Mt. Natagumo at midnight.

And just like in canon, a cannon fodder got dragged back into the mountain.

Just before they go in, "I will also go in," I said.

"But!" Tanjiro wanted to protest but I cut him off.

"Don't worry about Nezuko. Nothing will happen to her," I said with confidence. Looks like he got the smell of my emotion.

"Then, please!" Then he rushed behind Inosuke.

"Aren't you going too, Zenitsu-san?" I asked the one kneeling at the back.

"Nope! I am scared! And moreover, don't leave me alone here!" he screamed.

"Well, I've already told Tanjiro that I will also be going in. So… bye?" I walk together with Nezuko onto the mountain.

Our first date outside the town we were staying is inside the mountain that is filled with spiders and an oni family. Wow, talk about romantic.

"Are you scared?" I asked.

"No, you won't let anything happened to me, right?"

I just smile wryly at the coming question. If I can't protect the one who is beside me, I can just dream about protect other things.

We just wander around and surprise, surprise we didn't encounter a single oni. Is it our luck? I used so that the spider threads don't stick on our bodies.

After wandering for a while, I heard someone running in this direction. No, there are two. It seems they are running side by side. Looks like Nezuko also heard the footsteps. After a while, we now see who are the two mysterious people are. They are Tomioka Giyu and Kocho Shinobu.

Stolen novel; please report.

"Oh! The person who looks like he has no friend," Nezuko was the first one to make a joke of Giyu. Nezuko, do you really need to make fun of him? How much do you resent him?

"Fuhaha. Look, Tomioka-san. Even a random girl knows that you don't have any friends," Shinobu is laughing while both hands are on her stomach.

But Giyu said nothing. His eyes are on Nezuko. After a while, Giyu.exe booted up again. His eyes went wide, "You are that…"

"Yup, a former oni, Kamado Nezuko," she waves her hand at them.

"And this is," then she moves a little for them to see me.

"Urien Gregorios. You can simply call me Hiroto if you don't know how to call me," I gave them a curt bow.

"Tomioka-san, do you know them?" Shinobu seems confused.

"The girl, I remember her. She… is an oni," Giyu finally replied.

"Tut-tut tut-tuts, that is where you are wrong, Loner-san. Former, I am a former oni," Nezuko wave her finger left and right.

"How?"

"You need to save other Demon Slayers, right? My brother is also here."

"Tanjiro is? Which way?"

"That way." I pointed in the direction where I heard Papa Spider's roar.

"Thank you." And… he's gone.

"Do you mind telling me, what are the two of you doing here?" Shinobu asked.

"Oh! We are actually on a date." I show her the hands Nezuko and I are holding. Nezuko immediately came and held my hand at the same time Giyu left.

"Oh," Shinobu sweatdropped. "Holding hands, how lewd." I heard her muttered.

"I see…" I can hear the twitching sound coming from her forehead. I think she is angry because we are going on a date in oni's territory.

"I can hear some sound coming from there," I point in the direction where I heard Zenitsu's scream. I don't know why he still comes here even though he doesn't need to worry about Nezuko. Is it because he thought he was left out?

"Are you sure?"

"Yes," I nodded.

"Then let's go."

"Us too?" I pointed at myself.

"Yes."

"Well, let's go Nezuko."

"En!"

When we got there, I saw a Pikachu doing Volt Tackle on an oni with a spider body and humanoid head. Wow. It looks very beautiful when you see it in real life. I am in awe. Those lighting effects are awesome!

After a while, I see Shinobu giving an antidote to Zenitsu on the roof of the house. I look at Nezuko. She knows exactly what I wanted to do. She grabbed me and jumped with her oni strength.

"Yo! Zenitsu, how is it going?"

"Apologize…" he muttered. Wow. Even in this state, he can still say that.

"Well, Zenitsu, because you show me such an awesome sword skill, let me reward you."

"Girls?" Seriously dude. How the hell can you think something like that in this state. And can't you see Shinobu's smiles are getting scarier?

"No, I am saving you from bitter medicines."

"Please," a normal reply this time.

"Well then," I prepare myself.

I used my .

In that instant, his body shone, and… Wait, is Pikachu evolving? No, his body returned back to normal. No more short limbs, no more bite marks, and no more bloodstains.

"You," Shinobu smiles at me. How am I going to explain this? Not that I don't want to. It seems troublesome.

"Why didn't you do that before I waste my antidote?" Is that why she is angry?

"Well, I am going to the place where's Tanjiro at. Bye!" I got back to the ground by using my . Nezuko followed me shortly after.

When I got there, I saw Tanjiro doing 'Dance of the Fire God'. Seriously, anime did not do justice to how much this looks both beautiful and cool. The reason why we arrived sooner than Giyu? I cheated by getting the exact location with .

There is no Nezuko to help him with her 'Blood Demon Art'. Instead, I am here.

Another one.

With that, everything is finished. Well, not exactly.

"Yo! Tanjiro, are you having trouble?"

"Eh? Hiroto-san? And Nezuko too?! What are you doing here?"

"What you were doing looked wonderful, big brother."

"And a Demon Slayer that your sister knows is also here."

"A Demon Slayer that Nezuko also know? Is it Urokodaki-san? No, it can't be him. Is it Tomioka-san?"

"Do you want me to heal you or are you just going to lie on the ground?"

"Please heal me. I need to go back to Inosuke," he said. He is not going to refuse this time because of his friend, huh? What a good boy.

"Oh, the oni from before is not dead, you know?"

"What?!" he exclaimed. Not because of recovery but because Ruri is not dead.

"Don't worry about Inosuke. I am sure Loner-san is there," I told him not to worry.

"There are other people here. Doesn't matter. I will cut you along with them," Ruri starts walking and puts his head back onto the body.

At that time, Giyu arrived.

"Tomioka-san!" Tanjiro shouted.

"So, his name is Tomioka-san, not Loner-san," I said which I got a twitch from Giyu.

"Well, Tomioka-san, will you let me handle this oni? He messed up my brother-in-law and I am a little pissed, you see?"

He looks at me with the same deadpan expression that he looked at Inosuke. "Do you have your Sun Blade?"

"Nope, my words are enough."

He looks confused. I walk toward Ruri. Poor child, starved for familial love. But that's not my problem. He had already killed many people. If I pity him here, he will kill more and those blood will be on my hand.

When I saw him trying to use his 'Blood Demon Art', .

All of the red thread disappeared.

"Eh?" he was shocked.

"Well, then. Bye-bye now, Ruri. I wish you will have a family who will love you dearly just like your family from this life," I said. He looks angry but I know the fact that his parents love him dearly. And he knows it too.

And with that, an oni named Ruri is no more.

I told Giyu that I am too lazy to explain twice and thus I will explain once I meet Ubuyashiki Kagaya. And request for the Kamado siblings to come along to listen to the explanations.

After a while, a Kasugai Crow came and returned the message.

"Requests had been accepted! Requests had been accepted!"

I finally get to meet someone I can extort.
