World's Fastest Level up!

Several minutes after entering the dungeon. We found a place that could be used as our spot and for the time being we decided that we should focus on this place.

Today's objective was to teach Hana about the knowledge of adventurers, and if possible have her practice [Stock]. But…

"Would it be fine for Hana even if Yui and Rei are here too? Ooi, Hana-!"

I called Hana who casually came towards me to answer this question herself.

"What is it, Onii-chan?"

"No, it’s just, although today's main objective was to teach you the regulation of adventurers, if possible I also want to verify the way to use Stock. But Yui and Rei are here too right now, that's why I wanted to ask about what Hana thinks."

"No problem! Because I think it's fine to tell these two about my skill."

"Is that so? Leaving aside Yui, isn't today your first meeting with Rei?"

"The fact that you entrust me to decide means at least Onii-chan himself trusts Rei-san, right? Then, I'm sure it would be fine."

"… I see."

That shows how much Hana trusts me. And while my heart warmed because of that, my calm mind thought about something. It was about the fact that I haven't explained to Hana about [Transfer Within Dungeon]. In no way I haven't explained because I didn't trust Hana, but I was still deciding the right timing to tell her.

This was what I have always thought but [Transfer Within Dungeon] was completely different from any ordinary unique skills.

Although its usefulness in combat was considerably inferior to that of ordinary unique skills, the fact that it can raise my level up efficiency up to several tens of times more than normal was what made this skill draw a line from ordinary unique skills.

That's why I couldn’t lightly spread this skill without any backing. Because leaving aside if they're just trying to compete for me, there is a possibility that the opponents of those who are trying to compete for me will aim for my life.

"Backing….huh."

Putting it the other way around, I might be able to make it public as long as I have a backing. A backing that couldn’t easily be provoked and could also protect my sister, Hana. And that was likely either this country or something that I am familiar with, a guild.

However, if it's not a guild that owns at least multiple top-ranking adventurers in the world, it won't be very effective.

Which means in the end, it seems the fastest way will be for me to get way stronger than everyone. That's why, I decided not to tell Hana about this skill for a little while. Subconsciously, I thought about something like that.

Anyway, now that I’ve heard Hana's decision, let’s proceed to try her unique skill, [Stock], right away. Yui and Rei were surprised when I briefly explained this skill to them before we started.

"What an amazing skill. As expected of Rin's sister."

Rei folded her arms and nodded with a ‘I know it all' expression.

I wonder what kind of viewpoint she was in to say that. However, the one who had a bigger reaction was Yui.

"To think you possess a unique skill, amazing Hana-chan! And I'm sure Rei-chan also has one too. Then this means half of the people who are here actually have a unique skill! I'm surprised! What should we do, Rin-senpai? Both of us only possess normal skills. Somehow the two look more dazzling!"

"Eh?"

"Eh?"

Come to think of it, I haven't told Yui about that too.

Looking at my unintentionally surprised reaction, Yui displayed a stupefied expression. And the one who sent out the rescue boat was Hana.

"Yui-senpai, Onii-chan also has a unique skill, you know?"

"Eh?! I haven't heard about it, Rin-senpai! You traitor!"

"By the way, it seems to be a weak skill that is useless in battle, though."

"I know I can believe you, Rin-senpai! Please continue to get along with me from now on-!?"

While pulling Yui's cheeks with both of my hands, I looked at Rei.

*Muni Muni* 1

"Now that you mention it, Rei certainly also possesses a unique skill."

"Un–Magic Sword"

As she chanted, a visible amount of magic power gathered in front of her. And then–

"Quartet"

–The moment she chanted, four swords with Fire, Ice, Wind, and Thunder blades appeared in front of her. Then, while four swords were floating around her body, Rei opened her mouth.

"Just like this, I can create as many swords as I imagine. A sword that cuts through the enemy with a blade of the wind, a sword that explodes the moment it touches the enemy, and many more. Every time the ability of the blades becomes more powerful and complicated, a large amount of MP will be consumed, though."

"…. So it was like that, what a strong skill."

Previously, I have only seen the wind sword but now that I see the others directly, it was a quite magnificent view. In conclusion, she could create anything as long as it was in the form of a sword. Furthermore, it will also contain a magic element.

It was a powerful unique skill that didn't lose to that of Hana's.

"That was certainly amazing."

"Un, and it's very beautiful too!"

Being praised by Yui and Hana, Rei erased her swords while being a little embarrassed.

"So, Rin. What should we do after this?"

"Let's see… I wanted to have Hana try [Stock] but…"

As expected, the best way to quickly check the ability of this skill was to copy an attack-type skill after all. However, Hana could only copy Lv1 skills right now and the only level 1 skills I have are [Appraisal] and [Concealment] which weren't suitable for this situation.

Even so, there is nothing to worry about. Because there were two adventures in this place beside me.

Although I was sure Hana didn't invite both of them for this sake, luck could be called an ability too. As expected our Hana is a genius after all!

Therefore, I immediately asked Yui and Rei.

"If you two are fine with it, could you let Hana copy a Lv1 attack-type skill that you two have?"

The two who heard my request looked at each other and then answered after giving me a bold smile.

"Sorry, I only have level 2 or higher skills"

"I don't have any attack-type skill!"

Yosh, let's disband!
