Chapter 57: Possibility
Seeing Kanzaki was trembling in fear, as if expecting even greater bad news, Aisha gave him a piece of paper.
「This is the detailed data of Mitaka Yuuma’s “Mana Index”, it records two different kind of electromagnetic waves.」
「S-So, what’s the matter with that?」
「Take a look by yourself.」
When Kanzaki looked at the paper, he saw an unknown graph in there.
「What’s the meaning of this?」
「This is a data which showed the composition ratio of mana, and this white graph represents the 『Colorless Mana』.」
「Uhm yeah
 So?」
「Look at this part.」
Aisha’s finger pointed at the graph with a different color.
「The gray coloured area represent dyed mana.」
「Eh?」
「In short, on the whole of 460k’s mana, not all of it is colorless.」
「Hey, wait a minute! Are you trying to say
」
「Yes. Mitaka Yuuma should’ve already eaten an attribute magic gem! He has already started dying his mana.」
「He can’t even fu*king use magic! And he doesn’t seem to be lying about that. As a matter of choice, he should’ve said it during the interview if he can use magic, right?」
「There must be a special reason for that. But it doesn’t change the fact that he had already dyed his mana. Or maybe, he simply doesn’t recognize that as magic.」
「How much
 of his mana that has been transformed into “Magical Power”?」
「Looking at the overall ratio of this graph
 It should be around 100k mana has been transformed into magical power.」
「O-One hundred, and thousand!?」
Kanzaki directly dismissed Aisha’s statement since he knew that the cost of a magic gem to convert such vast amounts of mana into magical power was simply astronomical, not something feasible for an ordinary high school student from an ordinary family.
「I don’t know from where did he get the supply of magic gems. Kotaro, have you seen Mitaka acting strange?」
""
Kanzaki pondered silently upon hearing Aisha’s question. The Yuuma that he knew until now was just your average youth who for some reason couldn’t raise his mana index.
But, Does it mean he kept the fact that he could use powerful magic as a secret?
「He said it himself that when he measured his mana index on his own, the result was zero. Does that mean he lie to us!?」
Upon hearing his remark, Aisha touched her chin, pondering for a while. Then opened her mouth.
「Nope, a normal mana measuring tool can’t measure the amount of his mana. In a certain meaning, he did tell the truth about his mana index.」
「Then how did you manage to measure his mana with your measuring tools.」
Aisha smiled impishly as she explained the situation to Kanzaki.
「It’s simply because of the difference in the structures. The normal measuring tool is a delicate instrument which measures the miniscule amount of mana inside the body. But, Mitaka’s mana is literally overflowing throughout his body. That’s why commercially available measuring tools can’t measure his mana. It is just like how the tool which is placed in the dungeon doesn’t work when it is filled with mana.」
「That’s
 Also one of the possibility.」
「On the other hand, my home-made measuring tool is basically to be used for measuring the mana inside the dungeon. That’s why I made it in that shape in order to isolate the target inside the sphere. It can work just fine even in a place overflowed with mana.」
Kanzaki frowned as he saw Aisha’s triumphant look on his face. But he really had to thank her since her mana measuring tool did measured Yuuma’s mana, albeit the scale of his mana was leagues ahead of the entire world.
Aisha then mumbled something as she paced around the room.
「But then, why did Mitaka eat magic gems even after knowing that his mana index was zero back then? He shouldn’t be that stupid to not realizing such obvious fact.」
「Humph, doesn’t that mean he simply have no idea that he can’t eat magic gem without sufficient mana?」
「I don’t think so, that matter isn’t a secret and he can easily find out about it with his smartphone. I don’t think he’s such thoughtless person.」
Aisha pinched her chin, fell into a deep silence as her brain worked at full throttle.
It was her particular gesture when she was completely immersed in her own world.
「Hmmm, do you think that there’s a magic gem
 with mana index zero? But he should’ve known by a simple survey on the internet that all magic gems have a mana index
 Since that’s the case
」
Aisha’s brainstorm suddenly came to a halt.
「No way
 is it a magic ore?」
「What the heck is that?」
「If we’re talking about magic ore, some of them do have zero mana index. That matter is also open on the internet. The truth is, the mana index of those magic ore is too high for commercially available measuring tool.」
Aisha was visibly becoming more and more excited. Only scholar specialized in 『Black Dungeon』 would react to the term such as magic ore.
「Maybe, Mitaka Yuuma is related to the 『Black Dungeon』
 Nay, it’s definitely! I guess it’ll be faster to ask the person himself――」
「Wait, time out! If the person himself keep that matter a secret, there’s no way he’s going to tell us that easily.」
「Uhm? Ah, come to think of it, you’re right. I have to make proper preparations
 I definitely can’t afford to lose the best lab rat due to some sort of misunderstanding. Fufufufu
」
Kanzaki who looked at Aisha who mumbled an eerie laugh couldn’t help but worry about Yuuma.
「Kotaro! Bring Mitaka Yuuma to this place the day after tomorrow. I’ll handle the negotiation with him.」
「The day after tomorrow? Not tomorrow?」
「I need some preparation to secure my subjugation, that’s why you just need to bring Mitaka to this place and leave the rest to me. Kukuku.」
Kanzaki became even more worried about Yuuma as soon as he heard Aisha’s declaration.
