The Chairman of the Sadich Magic Tool Trading Association, Chairman.....Seyi Liberstar. I only knew his name, but I had never met him in person, but I was curious about him.
　When I visited Lilia-san's mansion, I got the impression that Sei-san was a first-generation person with a distinctive white beard, an experienced old man with a kind face and eyes that held a strong light.

''It's nice to meet you, Miyama-dono, I've heard a lot about you... it's a pleasure to meet you in person like this,''
'Oh, no, it's nice to meet you too. It's nice to meet you.
''Pluto-sama, Chairman of the Sedić Magic Tool Trading Association........................and the 'Great Sage of the Dead', you're a terrific customer. ''My lady?''
Hi, hi!
...at least hold out a little longer.

　Apparently, it seems that not only Kuro and Sei-san, but also Zechs-san is a fairly famous high-ranking demon race in the human world.
　

'.........Black is like this too, but he's the Dark Lord.
'Kite, let's at least keep it in our minds. It's all in my voice.

　The necklace I gave her as a gift is on her chest as she reacts to my muttered words, and to be honest, I'm too embarrassed to look at her face properly.

　Anyway, I show the visiting Black and the others to the reception room, Zechs and Sei-san say hello to Lilia-san, and then we get down to business.....　I feel like I'm forgetting something very important.
　This visit is not only to say hello to Lilia-san, but also to talk about the rights to the calculator I proposed, but did I tell Lilia-san that?

So long, Lady Lilia. Please have a look at this one.
"...What's this?　Is it a magic tool?
Yes, it was Miyama-dono's idea, and we gave it shape.
...What?

　 I didn't tell you as I thought........
　And then Lilia-san turns her head towards me as if she is about to make a giggling sound, and mutters in a voice that seems to crawl out of the ground.

''........Kaito-san?''
Yes?
What do you mean by that?
'Oh, no, well I asked Black before if he could make a tool for our world...'

　When I return the words while being frightened by Lilia-san's expression as if to say it was your doing again, she is silent for a while..............................and lets out a big sigh.

''Really, Kite, you're always so........haha.......sorry. Zechs-sama. So, what's that magic tool you're referring to?
This way. It is a computing magic tool.
Calculate?　With a magic tool!

　It seems that the people of this world have a strong belief that magic is magic and mathematics is mathematics and a different thing, so Lilia-san looked surprised at Zechs-san's words.
　And then Zechs-san takes out a magic tool about the size of a ping-pong ball...It's tiny!　Is that going to be a calculator?

　When I was confused by the fact that it's smaller than I expected, Lilia-san touched the magic tool with a nervous look on her face.
　Then the magic tool emits a faint light, and numbers and formulas appear in the air.
　Amazing!　A number floating in the air and the format of touching it... isn't this completely beyond our world's calculator?　Oh, no, maybe I can't do function calculations or something, but.......once again, magic is amazing.

　Lilia-san manipulates that magic tool for a while and turns to Black and the others with an astonished expression on her face.

''........It's a wonderful magic tool. Not to mention the Chamber of Commerce, I thought all the nobles and royal palaces would want it.......
Yes, and as for the magic tool, our company is the one who created the magic formula, but it was Miyama-dono who invented it. And Miyama-dono is a person that Chrome-Eina is very close to, and of course, we at the Chamber of Commerce have no intention of treating him half as well as he is.

　In response to Lilia's words, Sei-san spoke the part that seemed to be the main point.

''And as for our Chamber of Commerce, we believe that Lord Miyama is entitled to half of the net profit.
'Okay, I see what you're saying. That means that from now on, Mr. Kite will be receiving large sums of money on a regular basis. We're going to have to make sure that we're in charge of it and that we're the point of contact...
No, sir.
...What?

　Apparently, Lilia-san thought it would be a good idea to lend me the name of the Alberto Dukes' name because it would be a deal with the Chamber of Commerce, and I was about to tell her that I would agree to it in a firm tone of voice, but Sei-san interrupted my words in the middle.

''Miyama-dono wishes to transfer the profits generated in this magic tool to the Duke Alberto family.
"...What?　Uh, uh ... s-sorry. I think I misheard you....again, please.
''Lord Miyama wishes to transfer half of the net profits generated by this magic tool to Duke Albert and his family.
...What?

　This time Lilia-san froze completely.
　After a moment of silence as if time stood still, Lilia-san leaned forward with a huff.

''No!　That's just the benefit that Mr. Kite should get!　I can't take that from you!
No, but Lord Miyama wishes to...
No!　I will never accept such a thing--"Lilia-chan"--?

　If you think about it, it might be natural for this to happen, but Lilia-san, who is so serious that she can't seem to agree with the fact that it's called a transfer of interest, was throwing out words of denial with a desperate expression, but then Black, who had been silent, opened his mouth.

''........Crom Eina-sama?''
''I see your point, Lilia-chan. I'm not convinced that you're going to benefit from Kite-kun's help when you haven't done anything, right?
Yes.
''But, Kite, you don't need money at the moment. No, in fact, he even has more than 100 white gold coins right now?　I guess you'll just get in trouble if you get any more.
That's not...

　Lilia-san stumbles a bit at Kuro's words that quietly tell her.

''And Kite-kun, after a year... you'll go back to your world, right?　If you're thinking about Kite, you should rather take on that kind of hassle that can be a hindrance to you, don't you think?
....
'Of course, like I said before, I understand how you feel, Lilia. So why don't we do this?　Kaito-kun has the rights until Kaito-kun returns to his world, and then after Kaito-kun leaves, the rights will be transferred to Lilia-chan. What do you think?


　I should say Kuro, as expected, offered a good compromise, and Lilia-san nodded after a thoughtful look.
　I thought that was the end of the conversation, but Kuro now turns to me and opens his mouth.

''But from the Kite-kun point of view, you don't need any more money now, right?
'Yeah, honestly, I don't think I'm going to run out even now...'
Okay. So here's the deal I'll buy out the rights while you're in this world, Kite.
Buy it?
Yeah. I'm not going to pay for it. I'm sure you wanted a transferable magic tool, Kite, so in exchange for giving me the rights I'll make you a transferable magic tool.
Huh?

　Black's proposal was certainly a welcome one.
　I currently have more than one billion yen in Japanese yen, and I can't possibly spend it all, and even if I did, it would only be a problem.

　I've been wanting to get a transferable magic tool, and I was just about to buy one.
　But since I have no knowledge of magic tools, I thought I would consult with Kuro to get a good one, but if Kuro would make it for me, I would be grateful.

I'm going to give you the rights to the product in exchange for the rights so I won't make a half-baked product. I'll make it the best in the world.
'Nah, it looks kind of awesome... oh, and by the way, I forgot to mention that I had something for Black to look at...'
Yeah?
Mr. White gave me a magical crystal before, but...
White?

　Perhaps it was because we were talking about magic tools, but I suddenly remembered the magic crystal Shiro-san had given me before.
　In the end, I was in some kind of a hurry, so I put it outside of my awareness, but when I thought about it, the magic crystal that Shiro-san, the God of Creation, had given me could not be normal.
　So I was going to ask Black to take a look at it once.

　The white magic crystal that I took out of the magic box was received, and after looking at it from various angles, Black looked puzzled.

'.........White, what kind of thing you're building.......'
Well, isn't that an ordinary magic crystal after all?
''....Yeah. Ordinary magic crystals absorb and store the magic power in the air. How fast this thing is and how much capacity it can store is the purity of the magic crystal... but this one, I don't have that concept.
What does that mean?

　What is it, I have a very bad feeling about this.
　That natural goddess........what the hell kind of outrageous thing did she send us?

"This magic crystal.........is creating magic inside, and it has a capacity of all the magic of the high-level demon race, but.......
...What?
'As expected of White, it doesn't exist in this world... or rather, that you would easily create something that is beyond the bounds of common sense...'
....

　What are you really doing, White?　I've created something that is out of this world!　Ho, I mean really outrageous..............he's a mess.

Hmmm. I suppose so. You're right.　If you make it with this magic crystal, you can transfer from the human world to the demon world or something like that, and you can reuse it in a few minutes.
Well that's very tempting... can I ask you for a favor?
Yeah, I'm on it.

　It was obviously a substitute that I would not be able to have, but if I tweaked that natural goddess, the natural counter would just come.
　So I decided to ask Kuro to turn it into a magic tool for transition magic.
　It's true that if you can go to the demon world as well, it will be easier to go to visit Isis-san's place and so on, and I wanted a means of transportation.

''........Kite-san's range of activities will expand?　.... dizzy...

　As Kuro smiled at me with a gentle smile, I thought I saw Lilia-san muttering to herself with distant eyes.

　Dear Mom, Dad - Black and the others visited, and we had a bit of an argument over the rights to the calculator. Then I found out the details of the magic crystal that White had given me earlier. I knew that guy - everything is too messed up.
