As soon as I received the request from Oswald of the Ash Hawk Knights, I gathered Noir and Alexia, who seemed to be deeply involved in the development of this product, and decided to hold a meeting in the living room of the store and residence.

　I left the store in the hands of Garnett, Erica, and Leila.
　It was convenient that it was a day when all the main shop staff was at work.

''Well then, I want you to look over this document first.

　I show them the documents Oswald left for me, and explain the details of the request to them as well.

　He replied that he would accept the request for now, but whether or not he could realize it would be impossible to know without hearing their opinions.

　In some cases, I'll have to say no to Oswald again.

''I see. ...... So the priority is high portability and sustainability, and the reduction in cost is secondary. As expected, the Knights have plenty of room in their budget.''
But it's also important to be able to get the numbers right. We're going to get a lot of people to use it, so productivity is also important.
If you can design it, you can outsource the production. The only drawback is that the price will go up by that amount.

　Alexia thinks about it while nodding a small nod over and over again.

　When it comes to making it using crafted technology, it still seems difficult to 'get it done cheaply'.

　However, it would not be easy to meet the requirements if it is a magic tool.

　This is because this one has the problem of a 'limited number of people who can work on it'.

'That's right. It's not that we don't have a stock of design ideas, but we just don't have enough to fill them. It would be better if we could use magic tools to compensate for the stumbling blocks.

　Alexia waved her hand in a flutter as she said this, signalling outright that she had no more ideas at the moment.

'How about Noir?　Do you think you can handle it?
"...... heating, of ...... spell scrolling, is not ...... enough... ...Oh, right: ......
Apparently the spell scrolling makes it difficult to use while walking around.
"Open, or else you can use ......, but not from .......

　Ordinary spell scrolls have the very appearance of a scroll, and are characterized by the fact that they cannot be activated unless they are unfolded, and once they are used, the scroll itself collapses without being stopped in the middle.

　The former is meant to be a safety measure to prevent malfunctions, while the latter is a flaw that is considered unavoidable due to the principle of activating magic through the pattern drawn on the paper.

　One scroll per magic is expensive to produce, and since there is a limit to the number of scrolls that can be carried around, it is not a magic tool that is used casually in the main.

　The scroll of 'heating', which seems to be used relatively frequently, is able to take a long time to activate each time thanks to its low output because it's just a warm-up spell, but even so, the low portability was unavoidable.

'Then why not use spells?

　I'm going to mention an idea that came to my mind without thinking about it.

　The Spell Scroll is a powerful magic tool that allows you to use magic without having to have magic-related skills, but it has many problems in terms of usability.

　So, based on the knowledge of Eastern spell tools that I gained through Sakura, the miniature version of the Spell Scroll ...... so-called spellcasting tool was reduced to reduce the disadvantages of the scroll.

　It is a magic tool with magical patterns drawn on a palm-sized piece of paper, and although its effects are small in proportion to its size, it is a substitute that is easy to carry around.

It is ...... easy to carry, but the ...... effect is also weak, so if you don't ...... touch it directly... ...Warm, not ...... maybe ......
Well, it's kind of a no-brainer.

　Well, if it's a problem that can be easily solved, the Ash Hawk Knights wouldn't send Oswald all the way from a long distance.

　For now, I'll ask Noir and Alexia to come up with ideas that meet the required specifications with their respective skills, and I'll return to the store.

　As you might expect, it's difficult to do normal work at the store and product development at the same time, so I'll let them concentrate on this side of things for a while.

'Hmm, are those guys still in the back?

　Garnett, who was sitting at the checkout counter, looked back at me over his shoulder and wondered why Noir and Alexia hadn't returned.

　I sit down next to them, and while preparing to deal with the customers purchasing the goods, I briefly explain to Garnett the results of the meeting we had just had.

I thought I'd have each of you two come up with a plan from both the mechanics and the magic tools. In the meantime, I'll make a few prototypes, and I'll be sure to ask Sir Oswald which one he likes best.
Well, I guess so. That means we're going to be short of people in the store for a while. Shall I ask Sakura to help?
That's a lot quicker than sending a request to the Guildhouse.

　Of course, Sakura has a day job as an adventurer as well, so I'm assuming that if she's available, that is.

'...... Right. Hey, Erica.

　Garnett spoke to Erica, who was arranging the products on the shelves in front of the counter, with a look on her face as she suddenly thought of something.

You can't mix a potion that warms you up when you take it?　It's not that thing that's supposed to make you warm because it's hot, it's that thing that's supposed to raise your body temperature.
'There is one, but I think people over there are trying that much.　It's more of a northern medicine man's specialty, isn't it?
'Oh, I see that too,'

　Letting out a disappointed sound, Garnett leaned his weight on the back of the chair behind the counter.

　There was no way that the people living in the cold region of the continent's north were neglecting their research on how to survive the cold.

　They should be able to survive the harsh winter with all the means they can implement, and it's hard to imagine that the Knight Order of the Ash Hawk, the guardians of the North, are not benefiting from it.

　In other words, the job we're asked to do is to develop means that not even the Northerners, for whom surviving the cold is a matter of life and death, have been able to achieve.

　And this one's hand is a skill of two types that are rare among the general population: magic tools to the craft.

　A skill that was monopolized by certain cities until recent years and is still not very widespread, and a sub-skill of wizards who usually have little to do with the general public other than to make money.

　Making full use of the skills that can be called the two-fold sign of the white wolf shop, creating winterproof items that have yet to be put to practical use - even after all this time, this may be quite a painstaking task.
