Since everyone already had a way to leave, Yuzhou did not remain behind.
He transformed into Ultraman Tiga and headed straight for the Moon.
As for the strange radiance appearing on the lunar surface, Yuzhou could already vaguely guess its origin.
It was almost certainly something this world's Belial had created.
The Plasma Spark could undoubtedly be considered one of the universe's divine artifacts.
Back when Belial was still the infamous "Old Black", he had led an entire monster legion to invade the Land of Light—all for the sake of the Plasma Spark.
But no matter how sacred it seemed, the Plasma Spark was, at its core, still a technological creation.
And how many so-called "divine artifacts" had technology produced already?
The Giga Battle Nizer and the Giga Finalizer created by Planet Kushia.
The countless enhancement devices developed by Ultraman Hikari.
Even Zero's Ultimate Aegis—a gift personally bestowed by Ultraman Noa—had been successfully replicated through the technology of Ultraman X's universe.
That shield was supposed to be one of a kind.
"Looks like after being purified, Belial's way of thinking has become much clearer,"
Yuzhou muttered.
To be honest, he had often wondered—
Belial was clearly powerful, and his technological prowess was nothing to scoff at.
So why hadn't he simply made a Plasma Spark himself in the first place?
Even Geed had been created through genetic technology.
And the original Plasma Spark had been developed before the scientists of the Land of Light ever became Ultramen.
So why did becoming an Ultraman suddenly mean losing scientific capability?
Unexpectedly, after Yuzhou altered Belial's fate, Belial had truly begun researching a Plasma Spark of his own.
And now… it seemed he had succeeded.
Upon arriving on the Moon, Yuzhou was genuinely astonished by the sight before him.
The entire lunar surface shimmered brilliantly under the illumination of the Plasma Spark.
Particles of light and photonic energy filled the air.
The once desolate, barren ground of the Moon now pulsed with vitality.
It felt as though, with only a source of water, lush vegetation could immediately take root.
And in fact—
some regions had already turned emerald green.
Which meant those patches of grass and plants had water present.
As for why vegetation could grow at all, Yuzhou suspected it was the work of Belial or Fukuide Kei.
At this moment, Zero and the members of the Ultimate Zero Guard were also standing on the Moon, staring in disbelief.
Juggler's Blast-Type Tiga, Geed, and Orb were equally stunned.
Riku—Geed himself—wasn't just shocked.
He was actively searching the area for Belial and Fukuide Kei.
"Geed, my son—you've come."
A silver-white figure descended from the sky.
Everyone focused their gaze.
It was Belial.
"Father!"
Riku exclaimed excitedly, then asked,
"The light on the Moon…!"
"This is the Plasma Spark that Fukuide Kei and I developed," Belial explained calmly.
"It isn't as powerful as the one in the Land of Light, but it can continuously supply energy."
"Belial… it seems you truly haven't changed."
A deep, resonant voice echoed across the Moon as another figure descended.
Yuzhou looked up.
The newcomer wore a red cape, had massive horns on his head, and a thick beard on his face.
"Father of Ultra?!"
Zero exclaimed in shock.
No one had expected the Father of Ultra to personally intervene.
"Kenn!"
Belial frowned when he saw him.
"I told you—my affairs have nothing to do with the Land of Light anymore. Why meddle?"
"Belial," the Father of Ultra sighed, "after all these years, you still can't let go of the Plasma Spark's power."
He looked deeply disappointed.
But from Belial's perspective, this was absurd.
"Ken, even if I still care about the Plasma Spark's power—what does that have to do with you?"
Belial shot back.
"I didn't steal it. I didn't rob anyone. My Plasma Spark hasn't affected the Land of Light in any way."
"So why do you act as if I've done something wrong?"
"…That actually makes sense," Yuzhou muttered quietly, nodding.
Belial had only replicated the Plasma Spark to fulfil a long-standing obsession.
If he couldn't obtain it—why couldn't he make one himself?
In Yuzhou's view, the Father of Ultra's sudden appearance and reproach were entirely unjustified.
"Belial, listen to me—do not harbour inappropriate ambitions regarding the Plasma Spark," the Father of Ultra insisted, clearly ignoring Belial's reasoning.
"Uh… Father of Ultra," Zero suddenly interjected, "may I say something?"
"…Go ahead, Zero."
"Well," Zero coughed awkwardly, "what Belial said is… actually pretty reasonable."
"He hasn't threatened universal peace, and he didn't steal the Plasma Spark from the Land of Light."
"Honestly, this might not be our place to interfere."
"Zero, you—"
The Father of Ultra was completely stunned.
Riku, meanwhile, looked at Zero with visible gratitude.
"Yeah," Glenfire chimed in bluntly, "the old Dark Belial was definitely irredeemable, but this one seems different."
"This…"
Not only the Father of Ultra—even Belial himself was momentarily at a loss.
Zero and the Ultimate Zero Guard… were defending him?
The same Zero who had once been his sworn enemy after his possession by Reiblood?
"Father of Ultra," Yuzhou stepped forward at last, "having a Plasma Spark on the Moon isn't necessarily a bad thing."
"Ultraman Tiga?"
The Father of Ultra paused, surprised.
Even Tiga was siding with Belial?
"First," Yuzhou continued, "such a powerful light orbiting Earth will make hostile alien civilizations far more cautious."
"Second, Ultramen protecting Earth—such as Geed—gain an additional layer of security."
"Third, the Plasma Spark Belial created clearly lacks the mutation or forced-evolution properties of the Land of Light's version."
"So there's no need for you to be concerned about its existence."
"Tiga…"
Belial looked at Yuzhou, speechless.
Moments earlier, he had been furious—ready to fight the Father of Ultra outright.
Yet now—
Zero.
Tiga.
Former enemies he once dreamed of defeating—
All of them were speaking on his behalf.
For someone as proud and arrogant as Belial—
It stirred something he had not felt in a very long time.
