I look beside me. Yup, Nezuko is also naked. How did this happen?

[Host, you got lucky.]

{What do you mean, System?}

[Interdimensional Police Force nearly come and arrest you and put you into jail.]

{Wait, what? You mean Interdimensional Police Force is real?}

[Did you really think I would joke about them, host? Anyway, they had already gathered their force to arrest you. But, the testimony from Kimetsu no Yaiba's World Will made them retreat.]

{So, you want to say is that I was almost caught and the World Will saved me from them.}

[That is correct, host.]

{I need to thank the World Will then.}

[You shouldn't, host. She is not here anymore. And the reason why you almost got caught is because of her after all.]

{Wait, World Will is the girl? And what do you mean it was her fault?}

[Well, she got frustrated looking at you and Nezuko. So, she made the proprietress knock over some aphrodisiac into your meal by accident. Of course, the proprietress didn't know the fact that she knocked some aphrodisiac into the meal for your room.]

{Wait, System! That opened the whole new can of worm! Does that mean all the World Will can kill me if they don't like me?}

[No, host. They can only manipulate some force of nature in their world. They can't kill you. And this will be the first and last time you will experience like this, host. The higher-ups had punished her harshly.]

I pull off Saitama's face. {Okay…}

[The last thing she said before being punished is, "My ship had finally sailed!"]

I can't talk for a while. I was laying on the ground with Nezuko hugging my arm. Those two mounts are touching me. That is not what made me speechless. It was what World Will said.

{And System. Tell me about Interdimensional Police Force.}

[Your rank is not high enough to access that information, host.]

{How can I raise my rank?}

[You don't need to do anything, host. It will raise in time.]

{Then tell me everything I have access to about them.}

[Okay, host. They are the police force that arrests people like you, host. Reincarnators, transmigrators, or even drop-off in certain worlds are instantly known by the police force.]

{So, you mean they already know which world I am living.}

[Yes, host. They only interfere if those people cross their line in the multiverse they got into.]

Support the creativity of authors by visiting the original site for this novel and more.

{So, I will not meet with those reincarnators and transmigrators because they are in another multiverse.}

[You catch on quick, host. Yes, you won't be meeting with them. Do you know about ROB aka Random Omnipotent Beings and self-proclaimed gods that give out gifts?]

{Yes, why?}

[You can take them as lesser nobles who govern small territory, they also govern their own multiverse. And above them are higher-ups I had told you about. And just like nobility, you can think of higher-ups as greater nobles. Then, above them are royalties. And the Police Force is directly under royalties.]

{So, can you tell me who gave me the System?} I know it was Noir but I just need to make sure.

[You do not have permission to learn about that yet, host.]

As I thought. It was Noir. He got that mysterious looks after all.

[There is lower ranking than lesser nobles but you don't need to know about them. They only have 5 worlds of their own. And for all the nobilities that govern their own multiverse or worlds, each world can only hold two reincarnators.]

I see. Then there must be another one of the reincarnator in my world. I must proceed with caution.

{Then, anything about World Will?}

[You don't have permission to know that, host.]

{Okay, then. What kind of crime should I make if I want Interdimensional Police Force to arrest me?}

[Well, they will arrest you if you slave others, mind-control others, or mass genocide. You don't have to worry about slaves if your world has already slavery in it, host.

That is already part of the nature of the world and World Will approved of that. Police Force can't do anything if World Will approved. And the Police Force can't catch those who originally reside in the world even if they break the rule. They will ignore mind-control crime if you are in the Hentai world.]

Then, they won't catch Lelouch even though he uses mind control because he is originally from Code Geass world?

[That is correct, host.]

Oh, geez. Good thing I agreed with Gurguit's request. Although the System said that I won't get caught because there is already slavery in my world. But better safe than sorry, right?

Then, I felt something moved beside me. Nezuko opens her eyes and stares at me. I, too, staring at her. We are staring at each other for a while.

"You should go and take a bath now, Nezuko. We are going to see your brother," I said. She just blushed and went toward the bathhouse.

I also went to take a bath. When returned, Nezuko is already sitting seiza at the corner of the room. I also sit in front of her and said, "I don't know what happened but I will take responsibility." You should know girls cherish their purity in this era.

Nezuko just nod. But I swear I could hear, "En," from her. From what she told me; she gets hot while trying to move me toward the futon. Then I grabbed her and pushed her down under me. She didn't remember anything after that it seems.

So, yea. We should get to Tanjiro and get his blessing. Or to get hack by his katana. I don't know what will happen. The proprietress came and apologized because she noticed a trace of aphrodisiac in the meal. She said we don't need to pay for a week and gave us a week worth of fees back.

----------------------------------------

"Coagulations! I am very happy that my beloved Nezuko had finally found her love. Please take care of her, Hiroto-kun!" is what Tanjiro said. What the hell is wrong with the Kamado family?! Is he really happy to hand his sister to a stranger? Not that I admit that I consider him as a friend.

"Wait, Tanjiro! Isn't Nezuko too young to marry?" I asked him.

"What are you talking about, Hiroto-kun? Mother gave birth to me when she was 17, you know?"

What?! Too young!

"Are you sure you are okay with me marrying her?"

"Yes, I am sure she will happy with you."

"We just basically met 2 weeks ago." I stare at him.

"And you know I can tell apart good and bad people, right?" he just smiles.

"You got me there," I could only shake my head.

"Then, Tanjiro! Please let me marry your sister!"

"Sure, go ahead."

"You guys! This is embarrassing!" Tanjiro and I are talking like we don't see Nezuko who is sitting beside us.

"Yes! You guys don't have any shame! And you, Hiroto! (Wow he dropped -san part.) How dare you flirt with Nezuko-chan and got to engage with her while all I can do is lay on the floor. Give me back all the worries when I heard you guys encountered oni during your trip to the lake. If I know that would lead to this, I won't worry about you guys!"

Inosuke just blows out smoke from his boar head. "Marriage? What is that? Is that strong?"

Thus, I got permission from my future brother-in-law to marry his sister.
