Roughly a week went by since we were given the task of finding a way to open the Forbidden Box.
When we came back from school, we received a response letter from Tred-sensei all the way back in Bauer.
ãMy sincerest apologies, but please give up on that box. There are things in there that cannot be released into this world. Those things probably infringe upon the taboos of this word. If you do not want to be put under permanent surveillance for the rest of your lives like me, then please do not involve yourselves with it.ã
The neatly written characters in his letter detailed as such.
âSince this is the reply to our request that we got from Tred-sensei, it looks like we canât do anything, huh.â
Claire-sama grimaced as she read over the letter.
Even with her forehead wrinkled, Claire-sama was still cute.
âWhat should we do? Do you think you can do something about the box with your knowledge?â
âI know that itâs possible to open the box, but Iâm a little bit worried after reading Tred-senseiâs warning.â
Taboos of this world, being put under surveillanceââ both of those were such jarring phrases.
âRei, do you know whatâs inside the box?â
âYes. There should be a certain magical tool in there that Tred-sensei studied during his time in the Empire, as well as a notebook summarizing all of his research.â
âWhat does the tool do, and what is inside the notebook?â
âThe tool is a ring-shaped device used to amplify the wearerâs magical power. Itâs not exactly what you could call a finished product, but if you have the aptitude to wield the ring, the tool could greatly amplify oneâs magical power by a lot.â
âI see, I see.â
You mightâve been able to guess it by now, but the person that has the aptitude to wield the ring is none other than the protagonist, Philine.
âIâm not really familiar with the details of the notebook, but it contains data of human experimentation that was conducted in the Empire, and the remorse he felt over it. Tred-sensei was never mentioned by name in RevoLily and was just introduced as some researcher, but if weâre following the original work, it was said that Tred-sensei ended up losing his daughter during those experiments.â
âMy goodnessâ¦â¦â
If I recall correctly, the details in the records were actually quite descriptive.
A lot of inhumane experiments were conducted.
âI donât know what to expect when I see things like âtaboos of this worldâ or âbeing put under surveillanceâ, though. Perhaps we can just open the box now, and then ask Tred-sensei about it again later.â
âWeâd have to be prepared if he gets angry at us, though.â
Itâs true that Tred-sensei might end up getting angry at us, but itâs that Tred-sensei, after all.
It canât be helped if we somehow manage to open it on our own, so heâd probably give up on feeling angry pretty quickly.
More than anything, considering how he used words like âtaboosâ and âsurveillanceâ, I doubt heâd leave things be.
Iâm sure heâll end up explaining everything to us.
âSo, in the end, how do you actually open the box?â
Claire-sama was starting to grow impatient.
As expected, she seemed to be quite curious about it.
âYou know how the box has those magical stones embedded on it?â
âYes. The black, blue and red stones â with each of them representing earth, water, and fire attribute magic, correct?â
âYep. Youâd need to activate the stones by using the respective magical attributes on it simultaneously.â
ââ¦â¦ Was it really something that simple all along?â
Claire-sama somehow seemed defeated.
âItâs not. It really isnât as simple as just using three different attributes of magic on it. If it was that easy, the researchers in the Empire would have opened it by now. The magic has to come from a single person alone.â
âEhâ¦â¦. So in other wordsâ¦â¦?â
âYes. Youâd need somebody that can use earth, water, and fire magic. In other words, only a tri-caster or anybody ranked higher can open it.â
In this world, where even dual casters were rare to come across, there were very few tri-casters and quad-casters.
There may be some that I donât know about, but within my scope of acquaintances, the only people that I knew of were Manaria-sama, Tred-sensei, and Mei.
In RevoLily, during a visit to the Empire, Manaria-sama was asked for her cooperation in opening the box, but given our current circumstances, it would not be realistic to get Manaria-sama to come to the Empire right now.
âSo thatâs what we have to do, huh.â
âYes, weâll need to get Mei to try her best.â
âYou called~?â
âDid you call for Meiã¼?â
When they heard her name being mentioned, both Mei and Alea came out of their rooms and walked over to us.
âYeah, thereâs something we need you to do, Mei. But before that, can I ask you a question?â
âSure.â
âMei, you can already use magic now, right?â
âThatâs right.â
âWhich attributes can you use?â
âHm? I can use all of them already?â
ââ¦â¦ My child is such a prodigy, itâs almost troublesome.â
Her abilities still had so much room for growth, but even with that, she was already a full-fledged quad-caster at the age of six.
âI see, I see. Youâve been giving it your best, huh. So then, do you think you can use three different attributes all at the same time?â
âHmmâ¦â¦ Iâve never tried it, so I dunno.â
â⦠Right.â
Using multiple attributes simultaneously was not a very common technique.
For example, Iâm used to it since I used a fused technique called âWater Meteorâ back when I fought against Manaria-sama, but most ordinary people wouldnât even be able to think of such things.
âLetâs practice it for a bit, then. Letâs start with two. Try using earth magic in your right hand, and water magic in your leftâ¦â¦ Do you think you can pull it off?â
I cast both attributes of magic in each hand to demonstrate.
Without really doing anything fancy with the magic, all I did was circulate the magical power.
After staring at me with strong fascination, she poured all of her concentration into her hands.
ââ¦â¦ Something like this?â
âWow, you actually did it. Are you a genius?â
It was supposed to be a difficult technique to learn, but Mei easily managed to use both attributes simultaneously.
âIn that case, letâs try it again. This time, try using fire in between those hands.â
âOkay, Iâll try.â
From here on, this was something I only knew about in theory.
Even if Mei couldnât do this right away, I was planning to watch patiently for several days if I had to, butââ
âAh, I think I got it.â
ââ¦â¦ Seriously?â
While she mustered up her magical power, in addition to the other two attributes of magic she had in her two hands, she managed to get fire attribute magic circulating in between them as well.
Compared to Alea, Mei wasnât as quick when it came to remembering things.
But it wasnât like she was particularly slow at picking things up either.
However, perhaps she was a natural when it came to learning magic.
âYeah, thatâs perfect. You can cancel it now, Mei. Thank you.â
âHaahâ¦â¦ That was exhaustingã¼â
Mei said that as she hugged Claire-sama.
âItâs unfair if youâre just spoiling Mei! I want to be spoiled too!â
âYes yes, come here.â
âItâs fine if you come to me instead too, you know?â
âRei-okaasama is lacking in comfort and fluffiness, though.â
â¦â¦ Iâm not sad at all.
âIf this is the case, then I think itâll be okay if we ask Mei to do it.â
âYouâre right. Well then, I think we should contact Hilda to let her know that we can open it.â
âPlease do.â
âBut thereâs something that Iâm concerned about.â
âWhat would that be?â
âTo be honestâ¦â¦.â
I explained to Claire-sama what might end up happening.
âI canât take Mei to a place where that might end up happening!â
âNo, but without Meiâs help, we donât have any other options.â
âNo! If itâs going to put her at risk of danger, Iâll think of something else!â
âClaire-sama, I understand how you feel. Iâm not really on board with it either.â
âThen!â
âPlease calm down, Claire-sama.â
I put my hands on Claire-samaâs shoulders as she was getting heated up in order to soothe her before continuing.
âItâs true that I canât guarantee her safety one hundred percent. However, Iâll do something about it. Claire-sama, please keep Mei safe.â
âBut I wouldnât want you to endanger yourself either, Rei.â
âItâll be fine. I have knowledge of the original work, after all. I know exactly how to get everything to blow over.â
To be honest, I was actually a bit worried, but for the sake of trying to convince Claire-sama, I didnât mention it.
âPlease, Claire-sama.â
ââ¦â¦ I understand.â
She seemed a bit reluctant, but for the time being, I was able to get Claire-sama to voice her approval.
Now then, it was time to open the Forbidden Box.
