"Lisa, may I ask you a few questions?

"Mr. Cosmos, what's going on?

One day at noon.

When Lisa worked at the Demon King's shop spreading her reference books to study.

Cosmos mentioned something weird again, as usual.

"Actually, I went to Japan alone the other day"

"Uh, is it a trip? Nice. Where have you been? I might have been able to guide you if you were close."

"Travel or for a little hobby wild. I've been visiting some of the companies I personally started on Earth (there) and then stopped by some of the companies I dated to give me management advice, and then stock futures...... no, well, they don't matter now"

"No, no, no, it obviously doesn't seem like it matters!? Is that the one that's ok with all kinds of things!?"

"It's okay. I haven't done anything that would contradict your laws yet."

"Not yet."

"Can I tell you something about the stock brand that's going to go up 100% certain? Whoa, that's out of line. So I took the Shinkansen the other day when I was there."

"It's fine because if I ask, I'm not going to be able to go back... uh, are you talking about the Shinkansen?

While I was listening to some kind of information that I was curious about, but probably shouldn't know the details, I managed to see something to the point.

"No, it's not exactly about the vehicle itself, it's about what you ate in the car. It's called a station valve. Whoa, just in case, I'm not talking about an unhealthy station valve."

"Unhealthy? Uh, is there a healthy or unhealthy station valve? Oh, maybe there's alcohol on your lunch box or something?

"Hehe, Lisa is adorable."

"Yes?"

Later, I was curious about Lisa inadvertently searching the internet for the meaning of the word, eating technical time difference activated sexual harassment for nothing and turning her face bright red, but well leave the matter alone (* readers under eighteen should not ask or search people if they don't know what it means).

"So I'm talking about the station valve over the food, but this is really great! I was also surprised at the variety of ideas that have been put in place, as well as the richness of variations that take advantage of regional specialties."

"Oh, there's a lot of fame... that? Not surprisingly, it's a very matte feeling for Mr. Cosmos."

The story seems to be about the station valve I ate when I took the Shinkansen.

There are various types that take advantage of each region's distinctive colors, as well as ideas about flavors and containers. Like Lisa felt, it's really mattomo content for a cosmos. So much so that you feel too mattomo and on the contrary disturbing.

"Me, so I thought." Oh, wouldn't you make a lot of money if you sold this idea out in this world called Pak? 'and "

"Oh, good. You're the usual Mr. Cosmos."

But don't worry.

Again, it was the usual cosmos.

"But, Mr. Cosmos. Pak...... even if you imitate it, do you sell station valves as they are in this world? I may be able to sell it for rarity at first, but I don't think it's going to be as lucrative."

"No, of course not. Well, it seems interesting to think about a specialty lunch box that utilizes ingredients from each region, but this time my focus is more on containers, not food. As you may know, Lisa, there's something in the station valve that warms up when you pull a string attached to a container."

"Oh, I know. I know!

"Yeah, I was hoping I could apply that mechanism to make tools that could heat food without setting it on fire outdoors."

You sold the station valves sold in Japan intact, which may be somewhat topical at first, but won't even make a lot of money.

But it wasn't the contents of the lunchbox that Cosmos glanced at.

We're going to develop and sell a simple heating device with technology from around the world.

"From what I've looked into, it looks like the heating mechanism utilizes the reaction heat of the raw lime. When you pull the string, the plastic bag with the water breaks and reacts with the raw lime."

"That's how it worked out for you. Speaking of which, I've learned the same thing in school classes."

"You'll be part of the alchemy in this world. Raw lime is inexpensive and available in large quantities, and bags that store water will be manageable if you process animals, demonic stomachs, etc. Reaction fever is also a known phenomenon here, and I was wondering if it might be possible to use all the unknown technology to draw attention poorly."

"Ha ha, I've been thinking a lot"

I was also worried about Lisa because it was what she said it would be, but selling the new product that Cosmos had in mind wouldn't be a big problem.

Fire in the open is quite a hassle, and if you have a tool that you can easily prepare a warm meal or drink by simply pulling a string, few people should want to use it.

There are quite a few people in this world who come and go away from well-equipped cities, such as pedestrians and travelers, including adventurers, and the potential demand as a commodity is likely to be considerable.

"So, the foreground is longer, but this will be its prototype"

"Oh, did you already have something?"

And it looks like Cosmos had already actually finished the item.

Took it out of nowhere and put it on the table is a crate about a turn larger than a typical lunchbox. The lid on the top surface is closed. There is a small hole in the lower part of the outside, from which the pylon and string pop out.

"I see, pulling this will warm the contents."

"Yeah, so if you could just ask Lisa to experiment with this prototype number one and try it. You see, it's easier for people who know the original products sold in Japan to notice the problems."

"I'm not that familiar with station valves either, but, well, if that's the case, I'll let you take it. You mean this experiment, including from where it warms up, right?

"Yeah, pull me a gooey"

Lisa pulled a string on her lunchbox as Cosmos urged her to. Then, immediately, the whole lunchbox is hot with the sound of shoo and steam erupting. And even more...,

"You're getting properly warm. Now you succeed............ smell!? What is it, this smell!? Mr. Cosmos, what's in this lunch box!

Odor overflowing with the gushing steam.

Lisa pinched her nose reflexively and jumped away.

"Hehe, thanks for the good look. Yeah, it's fine, because it's a clean food. Specifically, it's crumby. I put the baked one on top of the white rice."

"Yeah...... why, depending"

"I was going to give you a souvenir the other day, but for some reason Alice refused to accept it. Because of this, I thought I'd divert it to experiments. It's pretty good if you try it, isn't it?

"Well, maybe it is,"

"And then, look, Lisa, I was wondering if you could enjoy your funny, cute reactions. Thank you for the reaction and rare expression as expected. Thanks to you, the rice will go on."

"Ugh, Mr. Cosmos!

A cosmos that cooks Lisa's expression of shame while mollying her hocahoka crumbs of rice. Lisa, taken entirely by the balls, was too embarrassed, and that's what she felt her face get hot as warmed by steam.
