The 【Making Box】——it provides one random crafting material every day from the selected crafting material type. Moreover, it allows duplicating the items but the success rate varies depending on the item's rank.

Myu who heard that I had an item like that and was unable to exhibit it's full ability came to the 【Atelier】.

"Onee-chan! Why have you kept silent about something so interesting!"

"No, that would definitely turn out cumbersome so I just kept it to myself. Also, don't call me 'onee-chan'."

Spitting out a sigh during the usual exchange, I responded.

"Also, I don't really want anyone to know. Where did you learn that."

"I know, I won't tell anyone. And the information source's a secret."

"Yes yes. As long as it doesn't turn troublesome. But, what do you want with it?"

"What kind of items did you get until now? I wanna know that first."

Complying to Myu's words, I have lined up the herb-based materials I have acquired so far in front of her. From the materials used for creation of potions and pills for 【Atelier】, the bad status drugs I have created myself and unknown crafting materials whose application I didn't know.

Describing each one of them, I taught Myu about them.

"——And these are classified as materials I don't know the use of. There's lots of nuts and fruitish things. Also, these are things I can't turn into seeds by using the 【Alchemy】 Sense's lower matter conversion."

"Since there's so many of these unknown materials, that means their appearance rate is quite high right?"

"That's not it, the Making Box has another function that allows me duplicate them to secure a multiple number."

"I see. So, do you have a guess what might the materials be used for?"

"Hmm. Right now I'm investigating it in the library using the 【Linguistics】 Sense, but my level still isn't high enough to obtain information of that level."

Also, I have no idea what kind of effect they might have. Simply trying it out would be a waste of materials.

"Hey hey, how about you try making a drug with it to try it out, mm?"

"Well, that's one way to do it... I guess."

Until now, whenever I tried the new item's effect alone, an outrageous bad status was applied to me making me lose consciousness and I was unable to learn what was the effect... it happened many times. That's why, it was a good chance in a sense. Myu was able to objectively determine what was the effect.

"...I get it. Then I'll make a potion out of it immediately."

"I'll look around the store until it's ready."

It was the usual thing, not thinking anything in particular I went to the workshop part of 【Atelier】 and through extraction I have produced a solution out of the unknown crafting material.

"I made it. ...hey, what are you doing?"

"Ehh?! Onee-chan you're too fast! It was almost complete!"

What was Myu holding, was the Earth Gel I made the other day. In addition to earthen-coloured synthetic mob's gel-like body, there was the fire element's Heat Gel and water element's Aqua Gel one on top of another piled up vertically, I wonder if she was trying to make a tower.

"The slime tower is almost done! Um, like dumplings! Or something like that!"

"What are you talking about."

Also, the Heat Gel was unable to support the Aqua Gel any longer and has started trembling... no, it's always trembling isn't it. Is it maintaining balance by shaking? Interesting... not!

'Heyyy! We were supposed to determine the potion's effect right!?"

"Oh right. Let's start!"

Myu picked up the three synthetic mobs and returned them to their original locations, then we have went down to the real thing.

"Well then, I'll drink the drug. Myu, look carefully what effect does it have."

"Got it. Leave it to me!"

After getting Myu's confirmation, I took a mouthful of the drug. The yellow tasteless and odourless liquid didn't show any effect as it entered my mouth. I tried to explore my senses for discomfort and the status menu for the effect, but I couldn't tell.

"Hmm. It seems like there's no effect. Now, next one."

After confirming it with Myu, I drank a drug. It had an extremely weak weakening effect and a sweet juicy aroma.

"I wonder if it's something like a salve. Well, I learned it doesn't have a strong effect... this is the last one."

After drinking about a dozen of potions,  we couldn't see any effect strong enough to affect my consciousness, when I drank the last drug, a change has occurred.

—— *ba-dump*. My heart started to bounce incredibly strong. My entire body has started to heat up, and I have squatted down on spot.

"Onee-chan?!"

"Haa, haa... it's okay. But, something..."

As my consciousness has turned ambiguous, Myu grabbed my shoulder to support me. In the menu, the bad status 【Charmed】 was displayed. So the last drug, was a bad status inducing one... as I carefreely considered that, a change in Myu in front of me has occurred.

"O-Onee-chan. Somehow, I'm feeling strange! W-what is this!"

Myu's eyes were tinged with seriousness, she put some strength into the arms grabbing my shoulders and pushed me down on the floor.

"Wai... what?!"

"I wonder? I'm also... 【Charmed】? I can't stop."

As we were, Myu hunched over as if riding me and she  shallow breath repeatedly. Somehow, I started to feel incredible danger. I tried to push Myu away, but I was unable to resist because of the difference in our stats.

"Helloo. Yun-kun, there's something I want to talk with you about... ah."

"Eh... Ma-Magi-san?"

"No, um, you're having some s-skinship with your little sister, right. Um, sorry to intrudee!"

S-she definitely misunderstood! The moment I understood that in my hazy head still affected by 【Charmed】, my mind has cleared up and I took out a bad status recovery medicine from the inventory, then sprinkled it on Myu.

The effect on both of us has disappeared, and we felt slightly uncomfortable. I need to explain it to Magi-san later, and learn why did this happen.

After that, I drank the medicine again to ascertain it. Myu realized it and tried to stop me in a hurry, but after drinking there was no change in my body.

"...why?"

"Ah, the drugs I drank mixed inside of me, and after becoming one my breath has induced 【Charmed】 state in you?"

"Grr, how embarrassing! It's Onee-chan's fault!"

"Uwaa?! Why are you so angry!"

"Hmph, I don't know you any more."

Puffed up in anger, Myu left the 【Atelier】.

After that, with much effort I managed to appease Myu and solve the Magi-san's misunderstanding. And, among the drug's materials there was a combination that spread out a weak 【Charmed】 status in a wide range. After adjustments it has turned into a perfume called 【Charm Fragrance】 that had an effect of attracting enemies, but that's a story for the future.
