The pitch-black, hollow eye sockets couldn't display the emotional reactions expected of a human.
But the overly intense physical reaction fully revealed Nanika's current state of mind.
There is fear, but more of it is panic.
This instinctive or soul-deep stress response was a scene that played out countless times every day in the natural world's food chain.
That's right.
It was like seeing a predator...
Nanika's feet kept shuffling backward, but the wall behind him made it impossible to put any distance between himself and Moses.
This unprecedented situation left the Zoldyck Family both shocked and uneasy.
Killua was the only one who was genuinely worried.
"Nanika, what's wrong..."
Killua immediately moved to Nanika's side, his face filled with concern.
Nanika adored Killua the most and would always respond to his words and actions.
However, this time-
Nanika didn't react to Killua's concern, but continued staring straight at Moses, and his feet showed no sign of stopping or slowing their backward movement.
There is no doubt that Moses was the source of Nanika's reaction.
"What's going on...?"
Although Moses was the one involved, his confusion was no less than that of the Zoldyck Family.
'Panic, fear?'
'If I remember correctly, the personality soul named Nanika in Alluka's body is one of the five known Calamities: the gaseous lifeform, Ai, which dependent on human desires.'
'However, this Ai, which resided within Alluka, had many differences.'
Moses remembered that in the original work's Election Arc, Nanika could feel sadness, grievance, and even cry.
In that sense, Nanika's soul seemed more human-like.
So, a panicked reaction from Nanika wasn't entirely out of place.
'But-'
'Why is he so flustered?'
A flicker of doubt flashed across Moses's eyes.
'Is it because of the peculiarities of my body?'
'Or is it...'
'The inexplicable Perception?'
It has been eight years since Moses came to this world, but he still didn't understand the true nature of the Perception.
Where it came from, why it existed?
He knew nothing.
He could only guess that Perception might have originated from the Dark Continent.
If this guess was close to the truth, then Nanika's current reaction-
Could be partially explained.
'If we could communicate, perhaps I could get useful information from Nanika.'
While Moses was thinking, he suddenly thought of the deceased Mammon.
Back then, this being from the Dark Continent had also shown an unusual reaction to him.
'Is this also because Mammon can see the existence of Perception?'
'And what did Nanika and Mammon have in common?'
'If I must say, Nanika was a manifestation dependent on 'desire', while Mammon was a manifestation dependent on 'greed'.'
'Both of these are the vivid representations of human nature.'
'Was there some connection between them?'
'Did my transmigration have anything to do with the Perception?'
Moses shook his head slightly.
'Rather than speculating aimlessly, I might as well take this chance to see if I could communicate with Nanika.'
'In the original work, Nanika only seemed to say 'Ai' in front of outsiders.'
Sometimes, the word 'Ai' sounds like the pronunciation one make casually when they agree to someone's request.
'If I want to communicate normally with Nanika, I might need Alluka's help.'
'But never mind that for now...'
'For now, let's get rid of the Thermal Light Species first.'
Moses set aside his thoughts and looked at Nanika, who had retreated to the wall.
No matter how Killua asked or comforted her, Nanika remained panic-stricken.
'Maybe I should close my Aura Nodes…'
Thinking this, Moses silently closed all his Aura Nodes and entered Zetsu state.
As the Aura surrounding Moses disappeared, Nanika actually began to calm down, though she still showed some residual stress when looking at him.
"Killua."
Seeing that Nanika finally calmed down, Moses turned his gaze and looked at Killua beside him.
Killua nodded at Moses.
Following the prearranged plan, he would make the request to Nanika to resolve the Thermal Light Species, and then Moses would satisfy Alluka's coaxing.
Of course-
This seemingly normal process was all to conceal the existence of the 'Command'.
"Nanika, make all the Thermal Light Species within the 'world map' disappear."
Killua spoke in a commanding tone to address the Thermal Light Species issue.
"Ai."
Nanika faced Killua and responded with her usual single word.
Afterwards, Moses, Killua, and Silva and the others, who were in the monitoring room, saw dark, smoke-like Aura surge from Nanika's body, thick and ominous.
But in just a few seconds, the overwhelmingly intense black Aura vanished without a trace.
Immediately after, the inky-black features on Nanika's face reverted to normal.
At this time, he had handed over the control of the body to Alluka.
"Big brother~!"
The moment Alluka regained control, he immediately pounced on Killua and hung there like a koala.
Killua smiled and gently stroked Alluka's hair.
Moses watched silently from the side, quietly took a few steps back, then took out his phone and sent a confirmation message to Cheadle.
Before the 'wish' had been made, he had already given Cheadle a heads-up.
So, shortly after he sent the message asking for confirmation on whether the Thermal Light Species had been resolved, Cheadle replied:
"It has been preliminarily confirmed that patients infected with the Thermal Light Species can now move normally under sunlight, but whether the Thermal Light Species has been completely eradicated requires further verification."
After seeing the content of the message sent by Cheadle, Moses was fairly certain that the Thermal Light Species had already been eliminated by Nanika's ability.
However, since Cheadle didn't know about Nanika's existence, she maintained a rigorous attitude towards the issue of 'whether the Thermal Light Species has completely disappeared'.
'The obstacle has been resolved. Next… let's see if I can 'communicate' with Nanika.'
Originally, Moses had planned to rush back to the Hunter Association immediately after resolving the Calamity.
But Nanika's reaction just now made him want to communicate with Nanika.
He wanted to see if he could get some useful information from Nanika.
Just as he was pondering this, Alluka, who had been clinging to Killua, suddenly let go, hopped down, and walked up to Moses.
"Moses, give me your liver."
Alluka stretched out her hands toward him, with a harmless smile on his feminine face.
Facing Alluka's abrupt and bloody request, Moses replied calmly, "Okay."
As soon as he finished speaking, he reached out and inserted his hand directly into his body.
Squelch-!
As blood splattered, a piece of liver appeared in Moses's bloody hand.
"Here."
Without hesitation, he placed the organ in Alluka's small hands.
Drip, drip-
There was a lot of blood pooled on the floor.
Alluka held up Moses's liver with some difficulty.
Seeing this scene, even though Killua was mentally prepared, his pupils still couldn't help but shrink.
Meanwhile-
Inside the surveillance room.
The already heavy atmosphere suddenly stagnated.
