Feitan's Nen Ability is called [Pain Packer].
The effect of this ability is to create a small sun with Nen, which can release high temperatures enough to incinerate living beings in moments, with an expansive range.
The origin of this small sun comes from Feitan's anger, and the damage suffered by Feitan himself will become the fuel for this anger.
Therefore, in unleash the full potential of Pain Packer, Feitan usually only uses this ability after being injured.
In fact-
There are not many opponents who can make Feitan use this ability, and they can be counted on one hand.
And it is worth mentioning that...
Extreme anger usually makes people lose their minds, so Pain Packer is an indiscriminate killing ability that does not care about the safety of companions. It also indirectly reflects Feitan's self-centered and reckless disposition.
When [Rising Sun], which represented the manifestation of Feitan's rage appears, everyone within the range will be burned by the high temperature, including Feitan who used it.
To mitigate the damage to himself, Feitan would conjure a specialized heat-resistant suit, predominantly red and white, which only left his sharp, narrow eyes visible.
Now, with numerous injuries accumulating and his attempts to defeat Moses proving futile, Feitan decided it was time to burn everything to ash with Pain Packer.
This was also the source of his confidence and trump card that enabled him to kill Moses.
…
As Feitan activated his Nen Ability, a torrent of overwhelming Aura erupted from his body, surging like a violent waterfall.
The intensity of his Aura surpassed even that of Uvogin at full power. Moreover, black lines shaped like skulls slowly appeared in the Aura, revealing a thrilling presence.
Biscuit and Shizuku, who were watching from outside the battle zone, were slightly startled when they saw Feitan's sudden burst of Aura.
The dark skeletal patterns swirling within Feitan's Aura bore an uncanny resemblance to Post-Mortem Nen, radiating a palpable sense of dread.
Just at a glance, they can tell that this Aura is extraordinary.
Moses looked at Feitan, who was shrouded in powerful Aura, and raised his eyebrows slightly.
He was aware of Feitan's Nen Ability, but what surprised him a little was the counterpoint between Pain Packer and Kyoka Suigetsu.
When the black sword cuts the target, it will leave 'seeds' in the wound that grew into black tendrils.
Multiple wounds and the target's violent emotional fluctuations will accelerate the growth of black tendrils.
According to the effect of this ability, Feitan's uncontrollable rage should become the main acceleration medium of the black tendrils.
However, the black tendrils wrapped around Feitan did not absorb any nutrients corresponding to the anger, and its growth progress only came from the multiple wounds inflicted by Moses on Feitan.
Otherwise, even if Moses stopped growing the black tendrils when he entered Zetsu state, with the double acceleration effect of multiple wounds and intense emotional fluctuations, even if the fight lasted less than a minute, the black tendrils on Feitan's body would most likely be enough to form an Eye of Sight.
However, the growth and spread of black tendrils is slower than expected.
It seems that-
The passive priority of Pack Packer should be higher than the emotion-absorbing mechanism of Kyoka Suigetsu.
That's why the black tendrils cannot absorb the anger from Feitan.
When Feitan was first stabbed, the black tendrils that quietly spread out from the wound showed no signs of accelerating.
The reason wasn't that Feitan's ability to control his emotions was extraordinary, but that those angry emotions were transformed into the fuel for Pain Packer in advance.
Moses originally thought that Kyoka Suigetsu could, in a sense, completely restrain Feitan's Pain Packer.
But now, it seems that he misjudged the priority mechanism in the Nen Ability System.
This is like the 'first come, first served' fulfillment condition mechanism of Manipulation-Type Ability.
The Manipulator who gets the right to control the puppet first does not have to worry about the right to control the puppet being snatched away by another Manipulator.
Although Feitan successfully activated his Nen Ability since it has the higher priority, Moses remained unperturbed.
However, to Feitan, Moses's calmness was infuriating, as if Moses were oblivious to the impending devastation.
Feitan was eager to witness the terror on Moses's face when his Rising Sun incinerated him to ash.
As he thought of this, the surging skull patterns Aura on Feitan's body suddenly shrank, and then attached tightly to the surface of his body.
Then, this dangerous Nen materialized into a strange suit with red and white as the main colors, covering Feitan's entire body, leaving only a pair of narrow eyes exposed.
"($&@$&&$%(%@ (I'll make you taste the agony born of despair)..."
Feitan muttered in his native tongue, and his Aura flared once more. This time, it surged with even greater intensity, which is obviously a combination of raw Nen and unchecked rage.
At this moment, Feitan was releasing his Aura crazily, and the Aura he emitted suddenly became more dangerous.
"Pain Packer..."
Feitan growled as the condensed Aura spiraled toward a focal point in front of him. In an instant, it formed a white core enveloped in crimson energy, a miniature sun radiating terrifying energy.
Moses looked at the Rising Sun condensed by Feitan, and could clearly feel the terrifying energy contained in it.
"Has your fuel reached its limit? I mean, is this your 'full power'?"
"…"
After hearing Moses's words, Feitan's foreign language stopped abruptly.
…
Outside the combat zone.
Biscuit's expression grew heavy and she murmured under her breath: "This... doesn't look good."
Shizuku also felt an indescribable sense of danger from the fire. Without giving it much thought, she immediately took a step forward and wanted to rush over to help.
"Huh?"
Biscuit noticed Shizuku's movement and, with sharp reflexes, grabbed her shoulder, holding her back, "Are you crazy?"
"But…"
"Get as far away as you can!"
Biscuit barked, cutting her off. She wasted no time debating, and swung her arm to hurl Shizuku toward one of the venue's exits.
Then, Biscuit looked at Moses and was about to remind him to retreat strategically.
However, before she could say a word, Moses raised a hand and gestured, signaling that he had the situation under control.
"That's not something to joke about..."
Biscuit swallowed the words she was about to say and let Moses do what he wanted.
