These Scans indicates that aura is truly passive but can be suppressed Guy ,Dino and Luminous's Butler were suppressing their aura on purpose while Leon and Luminous and also Dagruele wasn't doing the same it was working as a passive .If you aren't satisfied then I can try to find some more convincing ones .
The farthest was a man with bewitching red hair. If he was a woman, he'd undoubtedly be a beauty.
I understood from a glance, this person was dangerous.
When I tried to analyze him, I only obtained trivial information.
He has the same wavelength of irregular Energy quantity;just like Diablo.
In other words, His Energy level was high, but the data shows that he was a novice that’s not able to completely control his demonic aura.
However, my eyes cannot be deceived.
Or possibly, she may have deceived the analysis power of『Wisdom Lord Raphael 』, this information was likely fake.
To make the opponent see false information and misjudge histrue power.This allows someone to grasp victory before a fight by having an opponent underestimate them.
In my terms, it was to conceal power. In other words, it was for making it hard for an opponent to gauge your true power through suppressing your demonic aura.
But this person’s idea was to exploit the opponent’s information analysis ability.
Someone who’s made afraid by this kind of information was not worthy to be considered as an opponent.
Of course, someone who can’t perceive this as false information was out of question. But the problem is, even disregarding what was seen and just by deducting his Level, it was at Diablo’s level of power.
Scan 2 :
Behind her was a man who looked like a butler, he doesn’t make any movement just like a statue.
He certainly was an expert butler; with great etiquette.
He might have the same idea as me, as he suppresses his Demonic Aura, his ability level can’t be read.
Like this, I was surprised that he was the subordinate.
As for the beautiful girl, she leaked out enormous amount of Demonic Aura.
But, the girl’s demonic aura had random change in quality and quantity so it makes any reading pointless.
Scan 3:
And the one who tried to had a friendly talk with the girl was Dino.
As expected. A completely KY-person. (ED: KuukiYomenai, lit: Someone who can’t read air/mood)
This man was fearless.
But, he had enough power to back his attitude.
He emitted a large amount of energy, but most likely he suppressed most of it.
This one too, by using Jamming, he concealed his true ability.
If I try to analyze him seriously he would surely notice. What a shrewd guy.
Scan 4:
If I was my old-self, I would say, Explode! Or so I thought.
Though he was formerly a human, his aura was impressive.
He was fully clad with Demon Lord’s dignity.
In fact, his true power cannot be analyzed.
