Apparently, a different relationship is being established between Effe and Heine.

"Thank you, there's no sign of getting off..."

"The weather in the mountains can change easily, so do you want to eat lunch and see how it goes?"

That's right.

I had lunch in the horizontal hole and watched what was happening outside, but the rain only intensified and there was no sign of it coming down.

“Maybe not today.”

"I see... I hope it clears up tomorrow..."

"I'm sure Master Freuilstore wants you to rest for a while." You don't have to push yourself. ”

"... that's true, too."

I honestly don't have the feeling that Freuilstore is... but I'm very much in favor of the part that doesn't need to be forced forward.

It's not as dusty as it looks, but it's raining pretty hard. Climbing a mountain in this heavy rainfall is too dangerous. Especially Tetra.

That's why we chose to wait in the crosshole after lunch. Neither did Fufu specifically say anything about waiting. Rather, it was better that way.

”I'm suddenly out of hand... let's make something...”

"Master..."

Hmm?

Nil wants to say something, but it's hard to say. It's unusual for Nil.

"What is it? Do you have something to say?"

Um... I'd like to make a throwing knife...

"Throwing knife... that sounds interesting." What kind of throwing knife do you want to make? "

Of course, it's impossible to deny Nil's words.

I want this from Nil and she almost never says she wants to make it. Unless there's something else to do, Nil tries to do with her own strength first, rather than asking me. It seems that I am thinking as if relying on me is rude, but naturally it is not, and if I can do it, I want to fulfill Nil's wish. That's why I want you to say what you want to do and what you want without being too hard to say, but Nil, it seems that's not a good idea.

Because Nil thinks like that, I sometimes do things like this, but at that time, I'm a little happy.

”The throwing knife is a little more suitable for throwing...”

"I see..."

The throwing knife that Nil currently has isn't just for throwing, it's just a knife. It is cheap and fragile because it is made of iron and has not been trained.

This time, I was throwing a few bolts or hitting a rock in a fight with Mountain Cat, but that's all I needed to chip my blade. It is a fairly low durability substitute.

However, the throwing knife may not be recovered depending on the situation, so it is easier to use if it is so cheap.

If it is made with something that is very expensive, there is no waste. In my case, there is money and materials, so I may think that it is not cheating, but they are not infinite, and it doesn't make sense if the products that I made over time disappear with dozens of bottles in a few seconds. So I basically bought it.

Let's make it this time.

“What are you going to do with the material?”

"Iron or something cheaper is enough. I just want to change the shape and use it.”

Iron is a metal that can be quite abundantly harvested in this world, and when it comes to metal, it is mostly iron. In other words, it is a metal that can be obtained quite cheaply. Of course, iron is the most common metal in my inventory.

"It doesn't matter if it's made of other materials." Some materials are light. "

"I see... I'll throw the throwing knife with my arm, so if it's too light, the power will fall." Conversely, if you are too heavy, you will not be able to throw well. That's why the weight of a knife made of iron is just right. ”

I don't use a throwing knife, and if I throw one, I just throw it at you. It was like a Catapult if I told you.

In contrast, the throwing knife used by Nil has a handle and a blade part. If you don't throw it well, it won't work. Besides, the knife's own weight and arm strength are involved, so if you change the weight poorly, it may affect the throwing itself.

"I see... if that's the case, I'll use iron to make it."

Yes!

“What are you going to do with the shape?”

"Um..."

Nil will show me the notebook she took out, curled up and rolled up.

"I've been thinking about a few things... what do you think?"

The notebook Nil showed me is still lined with adorable pictures.

Some shapes are written down in pictures, such as objects that are even more elongated than the throwing knife, and objects like stilettos in which the blade part is conical.

You've been thinking a lot, haven't you?

"Yes, but... it's hard to tell which is the best shape..."

For once, I tried making something that looked like that with Earth Magic, but I didn't know which one was the best after all... "

As a result of choosing to become Nil, this is all that's left.

Yes.

"I don't know much about throwing knives either, so I don't know... they don't look like bad shapes either..."

What shape is most preferable should be more imaginable than Nil who is actually using it. Nil chose it, so at least it won't be of any use.

What I know is whether the air resistance is large or small, and where the center of gravity will be. If that's the case, Nil will know, and I can say that I know almost nothing about it.

"Hmmm... it's better to ask people who actually use these things, so why don't you ask Effe?"

Even Efda Black Dogs will often use throwing weapons such as throwing knives, and they will know something.

So, Nil and I took our notebooks and went to Effe.

Fufu, can you do me a favor?

"Oh. What?"

As usual, Effe was sitting alone by the wall, but when I called out to him, he would react without making an unpleasant face.

Compared to the beginning, the response to me was also much softer.

"I'm trying to make a throwing knife, but I want you to consult me on what shape is good."

"There are countless shapes of throwing knives."

"Actually, there are some candidates." Since Nil uses it, can you tell me what shape is the best when you consider it? "

I show Efraim the picture in Nil's notebook.

"... I see. It's not bad just for the shape."

"Just by the shape...?"

"... yes."

After all, Effe only has an attitude toward Nil... no, let's hear it at night. I'm talking about the throwing knife.

"Considering other things, does this mean that the shape is bad?"

“It's not that bad. If I wanted to use it, I could use it normally, or defeat the opponent. However, if you think about it in various ways, if you are asked whether it is the best form, you say no."

"It's not bad, but it's not the best." What's the problem? "

"First of all, it's the part with the handle." In this painting, it seems that some changes have been made, but they are all too specialized in the shape for throwing. "

"... hh? Because it's a throwing knife, isn't it a good thing?"

"That's right, as long as you throw it."

Ah!

Nil let out a sigh of relief. I think I noticed something.

"... what do you mean?"

I turn to Nil for answers.

"Throw the throwing knife. When I thought about it, I always assumed that the distance from the opponent, my posture, and such things were constant.

However, they are certainly not constant in the midst of battle. I don't know what kind of position my body is in, whether it is far or near.

Rather than throwing, there should be times when you can only deal with misery... right? "

Yes.

In other words... the shape Nil thinks of is the shape that matches the baseball pitcher's form.

If it is always determined that the ball can be thrown at the same distance and in the same position, there is no problem with the shape that matches it.

However, fighting is a fluid thing, like a defense that doesn't know where or how the ball will come from.

When I try to return the ball to the home position, I don't know what my position is, and I may have to throw it in the worst position.

When that happens, if the shape specializes in throwing too much, it means that it cannot be thrown without the throwing form being removed. To be precise, they will be thrown, but it is likely that it will not be effective against them.

“When we choose to throw a weapon, we think the best shape is one that can deliver effective power with just one finger.”

"A finger..."

"Is that possible?"

"For example..."

And he took the pebbles that were falling on the ground, and drew them, rubbing them against the rock that was on the wall.

"If you make a hook on the part of the handle like this, you can hook it on one finger and fly it with centrifugal force."

Efe's painting is the handles of the knife. The tip portion is shaped like a "J".

Aren't you going to get in the way?

"This is just an example." This is not the correct answer. If it gets in the way for the user, we should think of a different shape, but we don't know what the correct shape is. ”

"Do you want to stretch that far with one throwing knife..."

"It's a weapon or armor that saves our lives."

However, it is better to consider that a throwing weapon is basically disposable. That's why it's not good to be too clingy. ”

“That's a tough question… where are the compromises…”

"If you put too much effort and money into making it, you will hesitate to use it." If you take the trouble, your attachment will boil.

One of the advantages of throwing weapons is that they can be used to throw them away. It's the same as an arrow. "

"I see..."

"The part of the blade must also be absolutely straight. It is optimally shaped so that it can exert a certain amount of power in any throwing method, whether it is bent or branched.

Well, this is just the shape we black dogs want, so this isn't the right answer. ”

"No... thanks, I'll think about it."

Thank you!

What Ef is saying is not absolutely correct. The shape of the correct answer will vary greatly depending on the user.

However, if you think about it carefully, it seems that the throwing weapons used by the ninjas are also made considering them.

For example, Shuriken. It has the shape of a blade around its circumference so that whatever part hits the blade when it is thrown. No matter what the situation, the blade will always hurt the opponent.

Kunai also had a hole in the tip opposite the blade.

I thought that it was to make it convenient to carry it through the string when carrying it, and to prevent it from falling off when attacking the opponent by hooking a finger, but it is also thought to be a shape where even one finger can be thrown.

"It's so deep..."

"So, that's it..."

When I think about it like this, I think that things like Kunai and Shuriken are the finished system, but if I think that it is the best shape for Nil, I honestly don't know.

There is no doubt that it is a shape made with various things in mind, and it is a much easier shape to use as a throwing weapon than just a knife. However, there are still questions about the best shape.

In the case of Nil, there is a leg holster, so there is no need for a device to carry it. If the blade is shaped like a backslash, it will not fit in the leg holster, so it cannot be shaped like a backslash.

After considering the various conditions, I felt that Kunai and Shuriken were not suitable as a dedicated throwing weapon for Nil.

“How about this?”

"No, that would get in the way here." In that case, this is the... no, this is it... "

Nil and I discuss a good shape while exchanging opinions with each other in the rain.

"Nil, what are you doing?"

When Nil and I are yelling, Pilte comes to Nil's attention.

"I'm trying to make a throwing knife right now, but the shape is not definite..."

Throwing knife…?

Tetra, who was with Pilte, also joined the group, and the three women were looking at the painting.

Throwing knife... I won't use it either... so what are you thinking?

"What I'm thinking about right now is the handles." I decided to put the blade part off later and decided on the shape of the handle part.

We have some candidates... "

"In the end, you won't know until you shape it, do you want to make it once?"

"I see... what kind of material would be good in the end?"

"I see... when you turn the blade part into iron, the pattern will be light and durable." I don't think it would be a problem if it was made of wood if it was cheap, but maybe I could cut out the bones of monsters. It's a light metal like Lytium. "

"Among them, is wood or aggregate the best?" I don't think Lytium should be considered disposable. ”

"I see? No... I have to think about Nil's senses, not mine, so if Nil feels that way, I should use wood or aggregate." Which is better? "

"If it's made of wood, I think it's good for magic, so it's the most disposable..."

"It would be too fragile to be used in battle." Even if it's disposable, I want some durability if I use it in battle. ”

If it is made of wood, even if the handle is broken, I think it can be made immediately, but if it is used several times during the battle, it is too weak a stone. Disposable means that I can only use it with that feeling, but once I use it, I will not be able to use it again. The aggregate is better than the wood if you think about using it over and over again.

"In that case, let's make the handle part of the aggregate." The bones have limited usage, so there are quite a few of them, and you can even make a prototype bang. ”

Is that okay?

Of course.

I'll try to make this shape... "

“I'll try to make this.”

"Let me help you too!"

Would you mind if I tried it?

Looks like Pilte and Tetra could use some help. Tetra seems to be new to this kind of production, but it may be helpful when thinking about what she will do in the future.

"Well then, maybe you two can help me out." Tetra needs to be careful not to get hurt. ”

Yes!

This production is not in a hurry, so you can just go ahead and talk slowly.

Slowly make it while watching the unstoppable rain fall.

Nil and I are used to this, and we can do it right away. Whether Piltee has helped me several times before or not, she has steadily created the shape without saying anything.

"That's how it is..."

"Yes..."

After the work, Nil teaches Tetra how to make it. This kind of relaxing time is very good when the spirit is calm.

It's time to take a break.

In front of the three people who were working seriously, I served black tea and something like a simple grill that I bought at the stall.

You can eat Tetra normally, right?

"Yes, yes, I just got your permission."

"Well then, you three eat in portions." Don't be shy, we've got it ready for you. ”

“Thank you.”

When Nil takes it honestly, both Pilte and Tetra thank you. It's a cheap thing I bought from a stall, and if you thank me so much, I'll feel sorry for you...

"Ah! I ate too!"

Heine, who was vigilant outside, raised his hand and said, "Did you get invited by the smell?"

"Even if you don't shout so loud, I have it properly prepared."

I'll just give you a little heave for watching out.

“Eat for two. I'll take turns when I'm done eating."

"There's no need for a change." I'm just looking out. Honestly, even if you don't look at it, there's no problem if you cover it with magic, right? "

Well, that's right...

"Don't worry about it." I really enjoy talking a lot. ”

In contrast to Heine, who seems happy, Surakutan looks a little embarrassed... well, it seems like there's nothing I can do about it, so let's take charge of Surakutan in my heart.

She laughed at Surakutan for help and silently walked away to the Ef.

"I just saved you."

"There is no problem to that extent."

When I sit next to him with tea and baked goods in front of him, he takes the tea without saying anything.

So far, it has become clear that there is more opportunity to talk to him, but he basically responds to everyone with a cold impression. However, I don't think it was intentional, and I think it is the only way to deal with it.

Is it like an occupational disease in the role of a black dog? Or is it just Ef...? I don't know, but it doesn't seem like you're taking that attitude because you don't like it.
