Afterwards, the cosplay convention ended without any incident,

We all had come to a cake shop for celebration.

「I’m sorry!!」

A girl with thick glasses, sat up straight and bowed her head.

If I were to say who this girl is―

it’s『Ringo-san』.

Indeed, the girl with thick glasses, who was lined up in the front of the venue’s queue before, was Ringo-san……

「I’ve caused everyone trouble,

What can I do to apologize……」

Ringo-san seemed to feel responsible about Nose-pierced man, lowering her head many times.

「It isn’t Ringo-san’s fault!

It’s that stalker’s fault.」

Aya cheers Ringo-san up with utmost effort,

Ringo-san keeps on apologizing.

Elena and Mai-san have been trying to cheer Ringo-san up too……

Even if the cosplay convention has ended, Yurie-san’s tension hasn’t gone down at all.

Because of her holding the shoulders of Elena and Mai-san, who are waiting upon from the left and right, the two people couldn’t move.

I have to change the topic and the atmosphere here……

「Come to think of it, Ringo-san said the she wanted to design accessories, didn’t she?」

「N!? Ringo-san wants to make accessories!?」

「I want to make accessories as well.」

Aya and Yurie-san jumped into the fray as well.

「I can only design.」

「What kind of design?」

「I’ve brought the sketchbook with my drawings, wanna see?」

「Take it out quickly!」

Various accessory designs were drawn on the sketchbook which Ringo-san took out.

The girls entered in the accessory talk.

Umu, I couldn’t enter the conversation with such topic……

oh well, Ringo-san seems to have been cheered up too.

I was free since I couldn’t enter the girls’ conversation.

That reminds me, what could be the intention of Nose-pierced man, the stalker.

Since I put tracking beacon on him, let’s see how he is doing.

Nose-pierced man was inside a dirty apartment room.

And then, he picked up some kind of suspicious instrument―

What!

He begun to inject it on himself.

Ah, is it an insulin injection?

This poor youth with diabetes.~

But, oh my! It’s absolutely different!!

It seems to be a dangerous drug.

In the package of the drug injection, it doesn’t read insulin!!

And when I’m troubled at excessive danger―

「It has been decided, oniichan!」

Aya suddenly said.

「N? What has been decided?」

「We’ll have oniichan make the accessories!」

Somehow or another, whilst I’m not looking,

it seems to have been decided that each person will choose from Ringo-san’s design for me to make.

Don’t decide on your own!

Aya chose a good looking brooch,

while Elena chose a pure looking hair ornament,

Mai-san chose a hair ornament with cute feeling,

Yurie-san chose a ‘adult’ word necklace,

and Ringo-san chose a simple looking brooch.

I took a photo of the designs with my smartphone,

Aya promised to keep in touch with Ringo-san.

***

Like this, the eventful cosplay convention finally ended and we returned home.

「Can you make the accessories properly, oniichan?」

「I will manage to craft them somehow or another but it’s how to procure excellent raw materials.」

「I’d like mine to be platinum!」

「Aya, do you know how much platinum is?」

「I don’t~ know.」

I tried to check the price of platinum on the internet but―

It’s about 4k plus yen per gram.

「It’s so expensive!」

「You can do it somehow or another if it’s you, oniichan!」

「I can do it somehow or another!?」

「Can’t be helped, then I’ll permit silver.」

「Thank you very much.」

Hm? Why do I have to say thank you?

「Seiji-sama, are the 10 Aurum silver coins not usable?」

「Although the silver coins seems usable, is it going to be fine with Delaidos Kingdom’s law to damage the money?」

「There’s no such law in particular.」

「Then, it’s fine, huh.」

I took out a piece of 10 Aurum silver coin from the inventory and tried to observe it carefully.

「Umu, this silver coin doesn’t seem to be a high-grade silver.」

「Well, it might not be very good compared to the quality of Japanese products.」

If I’m not mistaken, there are impurities mixed in with this poor-quality silver.

I wonder if the impurities can be removed using magic?

I grasped the silver coin and tried it in various ways with【Earth magic】.

The result―

It was no good.

Although it could change the form but it couldn’t change the quality.

Umu, is there no other way?~

Pikon!

After a long time, a lightning・bulb・lit up on top of my head.

If Earth magic is no good then why not use Lightning magic!?

「【Electrolysis】!」

【Electrolysis】was cast on the 10 Aurum silver coins.

Then, the silver coin of about 200g―

Decomposed into 50g of tin powder, 50g of copper powder,

and 100g of pure silver powder.

There’s only 50% silver.

When I harden the pure silver powder using Earth magic,

a lump pure silver that shone beautifully was made.

「Uwa, it’s beautiful and couldn’t be compared from a little while ago.」

「It’s amazing! It’s just like a mirror.」

I, who got into the swing of it, tried even the 100 Aurum gold coins―

I was able to make 100g of pure gold as well.

The impurities were 50g of silver and 50g of copper.

When I checked the market price of pure gold, it had the same price as the platinum……

With only 100g of pure gold,

it seems to be around 450, 000 yen……

It’s dangerous, beyond dangerousssss!!
