(2/2)
 Behind me, the usual capsule toy machine appeared. It seems that the appearance position was offset because there was a desk in front. This kind of thing can happen.
 I placed my hand on the machine again and looked at them. However, they had puzzled expressions on their faces.
"…? Shouta-san?"
"Is there something there?"
"Can't you see it!?"
 The two of them looked at each other and nodded.
 This wasn't a face that was joking around. They really couldn't see it.
"Can you tell that I'm leaning on something?"
"Yes…"
"Are you just miming?"
"I'm not that skilled…"
 With this status and skill, it might be possible, but let's put that aside for now…
"I need your help."
 Saying that, I took their hands and made them touch it.
 Apparently, they could touch it.
"You can touch it but can't see it? If no one else can see it, then it could be considered a good find…"
"Hey, Shouta-kun, does this secret thing have a name?"
"Hmm? 'Level Gacha.'"
"'Level Gacha'…! Oh, it just appeared!"
"‘Eh?’"
 Aki patted the machine.
"Maki, say it too."
"'Level Gacha'? …Oh, it appeared! I can see it too!"
"You can't see it unless you know the skill name?? That's a really mysterious skill you have…"
 They were patting the machine with great interest. It was kind of cute to watch.
"Hey, but this part is different. It feels like there's an invisible wall."
"Really? Maybe it's because of Shouta-san's skill."
 Their hands were reaching for the "10 Gacha" button. Well, they were trying to reach it, but they couldn't quite get there. Maybe because the contents are customized for me with my skill, others can't touch it…
"This is to prevent it from being accidentally seen by others… or even pushed by someone with low 'Luck.' This feature is helpful… Aki, you're too curious."
"S-Sorry…"
"No, it's fine. We found out it's harmless in the end."
 I patted the sulking Aki, and she quickly perked up.
"Hehehe"
"This is Shouta-san's secret, huh? You can spend levels to get items… and even skills?"
"Yeah, that's right."
"Amazing… If this were known to the public, it would completely change the world."
"You can reset to level 1 with enhanced stats, right? It's super efficient for growth. I understand why Shouta-kun was so stubborn about not showing his level. So, what's your current level?"
"41"
"Just enough to use it! Haha, just like Shouta-kun."
"Shouta-san, can you tell us what has come out so far? For safety, I won't take notes. I'll remember everything."
"Eh? That's a bit much."
"Shouta-kun, Maki can do that much. After all, I'm your sister!"
 I patted the proud Aki and the pleased Maki, and relayed all the information I could remember.
"…Okay. I have a rough idea. 'SR' is a basic skill for dungeon exploration. 'SSR' is a superhuman skill. 'UR' is an unprecedented skill. Since 'UR' has appeared only a few times, I can't specify it yet, but I think this is generally correct. The priority of appearance doesn't seem to be related to the value or ease of discovery for us."
"Yeah, that's what I thought too. There's a mix of 'SSR' skills worth hundreds of millions and magic worth a few million."
 Maki really is smart.
 Just by recalling it, she has already organized it in her mind.
"Hey, hey, that's all well and good, but how about you actually use it? You were planning to, right?"
"Yeah, that's right. Let's do it."
"I'm looking forward to it!"
 With the two of them watching, I pressed the "10 Gacha" button.
*Jingle, jingle, jingle!*
 Two purple, four red, and four blue capsules came out.
* R: Strength +12
* R: Dexterity +12
* R: Magic +10
* R: Intelligence +12
* SR: Agility +25 (x2)
* SR: Skill: Auto Mapping
* SR: Skill: Throwing Lvl 1
* SSR: Intelligence +70
* SSR: Skill: Martial Arts Lvl 1
 I opened the capsules and showed them the contents to the excited girls.
"The contents are like this… Hmm?"
"Can't see it again…"
"Hmm?? Shouta-kun, what's that thing there?"
"Um, 'Magic +10.'"
"'Magic +10'! …Nope, it doesn't work. It's the same."
"Whaaat!?"
 Even after checking the items that came out of the gacha, they couldn't see or touch anything, including the skill orbs. It seems that the contents are also restricted to me, just like the "10 Gacha" button.
 But what about normal items that started appearing at 'SSR' and above? Can anyone see them, or are they also exclusive to me?

"Well, anyway, the enhancement items and skill orbs that come out of the gacha are for the user only."
"I once thought about selling the high-value enhancement items, but it seems that's not possible."
"If I had tried to sell something no one could see, I would have been worried about my mental health."
"Yeah…"
 I'm glad I didn't.
"Hey, hey, so this skill, did it really come from a slime?"
"Yeah, let's talk about that next."
"I'm curious!"
 And so, I forgot that I had someone waiting outside and began to recount the three years of hellish training.
