Biscuit was familiar with the top-ranked floor master of Sky Arena.
Even if she didn't know him personally, she definitely had some knowledge about him.
Moro picked up on this immediately and asked,
"You know him?"
"Something like that."
Biscuit wasn't joking around this time.
Though she had her own thoughts about the situation, she was being completely serious when evaluating strength.
"Orian, the last remaining successor of the Mind Illusion School."
...
Hearing the term 'school', Moro's expression turned serious.
Biscuit explained,
"In the past, various martial arts schools flourished, competing for dominance. Dojos challenged each other constantly, leading to countless battles.
But as time passed, most of these schools lost their place in the world and eventually disappeared."
"So, seeing a school reduced to a single successor isn't surprising.
But the Mind Illusion School is different."
Her gaze suddenly sharpened.
Moro subtly raised a brow—this was the first time he had seen this look in Biscuit's eyes.
Biscuit continued,
"Around six or seven years ago, the Mind Illusion Dojo was attacked.
Everyone inside—including the head instructor—was slaughtered."
"Orian was the attacker?"
Moro asked without hesitation.
Biscuit wasn't surprised by his question.
An entire dojo wiped out… yet one heir remains.
Anyone sharp enough would immediately connect the dots.
"Yes."
Biscuit nodded.
Moro frowned.
"Then how is he still…?"
"I know what you're about to ask."
Biscuit raised her gloved hands and said,
"But Orian has Dissociative Identity Disorder."
"…What?"
Moro thought he misheard.
Biscuit calmly repeated,
"You didn't hear wrong. Orian has Dissociative Identity Disorder.
In fact, almost everyone in the Mind Illusion School had it."
...
Moro's lips twitched slightly.
Suddenly, it made sense why Orian was able to stay on top of Sky Arena.
But this also made Moro curious about this so-called Mind Illusion School.
A martial arts school made entirely of people with split personalities?
If it managed to survive for so long, then there had to be something unique about it.
Most likely, it involved Nen.
Biscuit noticed his curiosity—she had seen this expression before.
"Interested, aren't you?"
"Yeah."
Moro didn't deny it.
Biscuit continued her explanation:
"The Mind Illusion School specialized in creating clones.
Its original purpose was to manifest clones that could absorb and remove both physical and mental damage from the main body.
At first, this idea sounded ridiculous, but with Nen, it wasn't impossible."
"However, they soon encountered an issue—difficulty.
Even with Nen, creating a full human clone that could remove injuries or mental stress was far from simple."
"But instead of abandoning their idea, they found a shortcut—
Using 'Dissociative Identity Disorder' as a natural mechanism to drastically lower the difficulty of materializing clones."
Moro's eyes narrowed.
Biscuit nodded and continued,
"So, it's not that everyone with DID could join the Mind Illusion School.
Rather—those who joined the school actively developed DID as part of their training."
"In doing so, they successfully manifested clones representing their different personalities or emotions."
"This not only reduced the complexity of materializing clones but also allowed them to give these clones unique abilities."
"Eventually, these clones even gained independent consciousness and free will."
Biscuit paused, watching Moro's reaction.
Moro frowned slightly, then met her gaze.
"…This shortcut may have lowered the difficulty of materialization, but it also greatly increases the risk of mental instability.
Nen contracts are always fair."
"Exactly.
The Mind Illusion School was destroyed because Orian lost control.
One of his clones slaughtered everyone."
Biscuit stated calmly.
"But it's hard to say whether it was truly an accident, or if he let it happen on purpose."
"I'm telling you this because Orian isn't a normal Materialization Nen user.
He's powerful."
"…That's fascinating."
Moro's eyes glowed with intrigue as he placed a hand on his chin, thoughts racing.
"…Did you just say 'fascinating'?"
Biscuit blinked in disbelief.
But Moro wasn't listening anymore—he was deep in thought.
Psychological disorders can greatly impact a person's thought process and life.
In normal society, such conditions are seen as weaknesses.
But with Nen… an 'abnormality' becomes a weapon.
That's fascinating.
A normal person sees delusions as delusions.
Just like how someone from the real world would see a digital world as just a program inside a computer.
That's a logical perspective.
But for someone with a mental disorder, their delusions are their reality.
And if they truly believe it, then creating it with Nen becomes easier.
If one could overcome the risk of losing control, this truly was an unparalleled shortcut to immense power.
Then, another thought struck him.
Netero's Mind Force School.
If that was the right path, then the Mind Illusion School was its dark counterpart.
Mind Force focused on mental clarity and control, allowing the user's Nen to follow their will.
But Mind Illusion let Nen control the user's mind—a completely opposite approach.
It was a path of madness.
…And yet, it reminded him of something else.
The mysterious Tree Hollow Organization.
An elder from their group once said:
"The Eye of Truth hides a world of delusional madmen."
Could it be?
Was that organization also filled with people suffering from mental disorders—using their 'abnormalities' to push the limits of Nen?
Perhaps such methods could even break free from the normal limitations of Nen attributes.
There was already one clear example—Palm's "Silent Deep Sea Fish."
A Reinforcement-type user, yet she developed a complex Materialization ability.
The more Moro thought about it, the more intrigued he became.
Meanwhile—
Biscuit watched his silent contemplation, and a realization dawned upon her.
"So that's it… This is why…"
"This annoying guy grows stronger at such an absurd rate."
