[Congratulation, Host. You will be going to Kimetsu no Yaiba.]

I sighed with relief. Thank god. Most of the world on the list is full of suffering. What if I got into the already ruined timeline in Honkai Impact the 3rd? I'll be royally screwed.

[You will get two days to prepare, host. When you travel there, the time here will stop. Details about what you need to do in that world will be sent to you during the teleportation.]

I went back to the mansion after cleaning myself inside the lake. The view of the lake is very peaceful. It has clear water with the moon hanging over it. It is truly a beautiful sight. Without thinking further, I put on my clothes and quickly went back.

Luna is already waiting for me at the door. "Welcome back, Master. Did you get any injuries?"

"I am back, Luna. And like usual, none."

"Then, I am glad, Master. Will you be having a late-night snack?"

"Yes, please. Oh, and another thing. The place for my first Multiverse Travel is already decided. I will be going in the next two days," I said while she is leading me toward my bedroom.

"Do you need something before you go, Master?"

"Nothing, just bring me the supper. I am hungry after moving around," I said after sitting on the bed. Yes, I am eating on the bed. Something that an evil person does.

I spend the rest of the time I had training with Gurguit, looking over the documents, and drinking tea. And now, the day has arrived. The day for me to go on my very first Multiverse journey.

"Please take care, Master," Luna told me while giving me a bow.

"Okay!" I gave her a thumbs up.

[Preparing the connection.]

[Connection established.]

[Transporting host to Kimetsu no Yaiba world.]

[Success]

[Making identity for host.]

[Success]

[Making quests for host.]

[Success]

[Breaking the restriction place upon your magic.]

[Success]

[Kimetsu no Yaiba's World Will welcome you, host.]

And just like that, I woke up inside the ship. I get up from the bed and walk toward the mirror and see myself as 15 years old. Hmm… not bad. I look pretty cool. More so than Gurguit. Yes! I will grow up to become a fine man.

[Numbers of quests to do in this world – 2]

[1. Learn a breathing style.]

[2. Kill Muzen.]

[Host's identity.]

[An orphan visiting from the western country as a tourist after working himself to the bone. Learned about the Land of Rising Sun from a friend who visited the country and had a dream to visit someday.]

{How about language? How am I supposed to understand them?}

[You don't have to worry about that, host. Whenever you travel to different worlds, you will automatically understand their main language.]

{Well, that's good enough.}

{And can you tell me what kind of Word Magic> I have?}

[Word Magic]

[Any word you said will become reality.]

{That's it? No restriction?}

[Just got the message from the higher-ups. Word Magic> will now have the restriction. You can not use the Word Magic> to pass the world boundary. For example, you cannot summon from Nasuverse when you are in a different world.]

{Did you guys just Nerf me? Me and my big mouth.}

[You will get when you get back to your world as a compensation.]

I can only cry silently in the corner.

After staying up for a while, the ship had successfully landed on Tokyo Port. After getting down from the ship, I looked around the city. While I was buying dango with the money I had in my pocket, I heard some of the customers are talking about an interesting thing.

"That kid was crazy. He didn't move even when adults from the police force prying him off," some random man A said.

"And what are those flower patterns? I think I was drunk without drinking sake," random man B said.

Then I go near them. "Excuse me, I heard something interesting. Can you please tell me when did that happen?" I asked while handing some money into his hand.

"Oh! A foreigner. To answer your question, according to the police officer who has the clock, it happened around nine o'clock," random man A replied.

"Thank you," I smiled at them.

Now, let's go to Tamayo's home. I asked for a paper from the shop. While looking at the paper, I said,

And a map suddenly formed on the paper. Wow, word magic is truly overpowered. I followed the map and saw the dead end. Without any hesitation, I walked toward it and I appeared at the other side. And… I hear the sound of battle.

3rd POV

Tanjiro is currently having a hard time fighting the two onis in front of him. When he rushed toward the male oni, he saw the opening thread. Just when he was going to cut him, the thread snapped. And he got pushed backward, no. He was dragged by the arrow produced from the oni. He got dragged in different directions.

"It hurts!" he muttered. "I mean, this time it hurts so much!"

He was directed to high above. And this time, there is no force dragging him. Just as he was about to slam toward the ground, he uses a form that will lighten the impact.

"Eighth Form: Waterfall Basin!"

He is very tired now. But he mustn't give up. He still needs to turn his sister back into a human.

Just as the others start talking, all of them heard the sound of footsteps. When they turn their head to look, they saw a foreigner wearing a white suit. He looks like he is in his mid-teens. Tanjiro tried to warn him not to come here but he couldn't move.

"Er… Am I interrupting something? I came here to ask for direction," the boy asked.

Urien's POV

"Er… Am I interrupting something? I came here to ask for direction," I said the word what most people used in this situation.

"Hah? Where does this foreigner come from?" the female oni asked.

"Doesn't matter. We will kill him together with the others," the other one said.

"Hey man, you look like you were used as a ball to bounce around. Are you okay?" I asked Tanjiro without minding the oni duo. I saw him smile shyly. Seems like he was shy because what I said hit the mark.

"Hey, you! Don't ignore us!" the male oni tried to use force by showing his eyes on the palm.

I used my word magic.

Tanjiro and others look surprised that the two onis couldn't open their mouth.

I used word magic again.

Then, I turn my head toward Tanjiro.

"You can stand up now," I said. He looked surprised. Rolling his shoulder to see if he hurts.

"You should do your job first," I pointed at the two onis with my thumb. He looks determined and rushed toward them.

"Water Breathing Fifth Form: Blessed Rain After the Drought!" He slashed the two with a single slash. As I thought. He is a kind young boy.

Water Breathing Fifth Form is also called a "sword strike of kindness" as it decapitates the opponent in a single flowing strike that causes little to no pain. It is used when the enemy willingly surrenders. Even when they hurt him, he still shows them kindness by using this form.

After everything is done, one human and 3 oni turn toward me. It was Tamayo who started the conversation.

"How can I help you?" she asked.

"Oh yeah. I was looking for a way to here. And it seems I was lost," I showed her the map and point at the random place near Mt. Natagumo.

"Sir, they are in opposite direction," Tamayo sweatdropped.

"You need to go like this and this," she then told me the direction by drawing arrows on the map.

At that time, Tanjiro came and thank me. "Nice to meet you. My name is Kamado Tanjiro. Thank you very much for saving us before!" his gratitude is full of energy.

"It's okay. Don't mention it. My name is Urien Gregorios. You guys can just call me Hiroto if you think my name is complicated. You are from the Demon Slayer Corps, right? Your Water Breathing form is excellent," I gave him a thumb up while telling him the name I made up on spot.

"Eh heh. Thank you. And this is my sister Kamado Nezuko. I am sorry, she can't introduce you herself because she couldn't talk."

"I don't mind. It was me who was surprised to see oni who have self-control," I am still going with clueless mysterious man persona.

All of them, except Nezuko, eyes went wide.

"I mean, the battle here is so intense that it can't be between the humans, you know?"

"Ah… yes. I am currently looking for ways to change my sister back to human," Tanjiro said while rubbing the back of his head.

Yoshiro looks wary and Tamayo still has a blank face.

"Then, can you let me try something?" I asked. I can't miss the perfect chance to test out the limit of my Word Magic>.

"Eh?" Tanjiro didn't get what I mean.

"Nezuko, right? Can you hold out your hand?" I told Nezuko, who just went along with what I said.

I then hold Nezuko's hand and said

Nezuko fell asleep after that.
