"I didn't expect anyone to willingly step into this hell."
Tartarus' figure emerged before Yuzhou and the others, suspended within the golden space itself.
Below him, waves of golden energy surged endlessly—identical in nature to the power he commanded, as though this entire realm were an extension of his will.
"I came here willingly?"
The Belial of this universe assumed an attack stance and stared coldly at Tartarus.
No matter how arrogant Belial could be, even he understood that fighting inside an enemy's home ground was an extremely unwise move.
"Ahem…" Tartarus coughed lightly.
"That… was merely a momentary oversight. I pulled in the wrong person."
Alternate Belial: "..."
"Regardless," Tartarus continued, his voice turning icy, "once you've entered this hellish world, there is only one fate awaiting you."
"Death."
He raised a single finger and pointed at Yuzhou and the others.
"You're that confident?"
Yuzhou showed no fear whatsoever.
In Glitter Form, his energy consumption was completely unlike Zero's Shining Ultimate—there was no rapid drain.
On the contrary, his power felt inexhaustible.
"Then come and try!"
With a cold snort, Tartarus launched his attack.
"Riku—Royal Megamaster!"
Yuzhou's body erupted with radiant light.
A Glitter Circular Shield formed seamlessly around him, protecting him from every angle.
Before charging forward, he gave Riku a quick command.
At such a critical moment, Riku did not hesitate.
He immediately used the Belial Capsule and the Ultraman King Capsule, fusing and ascending into Royal Megamaster.
Meanwhile, the Belial of this universe turned his attention back to his alternate self.
Tartarus was infuriating, yes—but Belial knew one thing clearly:
The Belial from another universe was his responsibility.
BOOM—!!!
Two pillars of golden light collided violently, rippling through the space and sending waves of distortion across the entire golden realm.
"I didn't expect your energy to be this powerful," Tartarus remarked coldly, his expression unchanged as he addressed Yuzhou.
"Is that so?"
Yuzhou replied calmly.
He raised his arms.
Not the ordinary Zeperion Beam—
But the Glitter Zeperion Beam.
Sensing the threat, Tartarus mobilized the power of the entire space, merging the golden realm's energy into his own body.
A torrent of violent golden energy erupted from him, surging straight toward Yuzhou.
As expected, the two beams clashed head-on.
Two energies of identical colour—but vastly different nature—collided violently, splashing golden, liquid-like energy in every direction.
Others might not realize it, but Tartarus knew very well—
Each droplet of that scattered energy was enough to drive thousands of monsters into uncontrollable frenzy.
"You can't maintain this form for long, can you?"
Tartarus said while continuously outputting energy.
"Yeah," Yuzhou answered, deliberately sounding tense.
"Only about three minutes."
"Three minutes?"
Tartarus burst into laughter.
"Then you're dead for sure."
To him, victory was already secured.
So this was the limit of Glitter Tiga?
Impressive—but ultimately insufficient.
The beam clash lasted the full three minutes.
On the battlefield below, the alternate Belial had already been subdued by Royal Megamaster Geed, lying motionless on the ground, his chest rising and falling weakly.
The Belial of this universe stood silently nearby, watching his counterpart—
And notably, did not deliver a killing blow.
After all…
That was still himself.
Just a version from another universe.
"Three minutes are up," Tartarus declared.
"Game over."
He increased his output.
What surprised him, however, was Yuzhou's composure.
No panic.
No attempt to retreat.
"Are you waiting to die?"
Tartarus asked, puzzled, as his golden energy gradually swallowed Yuzhou's beam.
Though an enemy, Tartarus knew one thing—
The Tiga before him was not foolish.
Yuzhou did not answer.
Instead, he subtly adjusted the L-shaped position of his arms.
In the next instant—
Boundless light erupted from between his arms, completely engulfing Tartarus' golden energy.
"What?!"
Tartarus was utterly shocked.
He had been certain Yuzhou was at his limit.
Yet now, his own power was being swallowed instead.
As the golden Glitter Zeperion Beam surged toward him, Tartarus instantly opened a golden wormhole and vanished.
Whoosh—
The beam plunged into the golden energy sea instead.
The impact triggered massive waves, shaking the entire golden hell violently.
Yuzhou dispersed the energy between his hands, genuinely surprised.
Tartarus had fled.
He ran—
Inside his own domain.
Royal Megamaster Geed hadn't even had the chance to move, and Tartarus never experienced the might of Ultraman King's power.
Walking over to Belial and Riku, Yuzhou glanced at the defeated alternate Belial on the ground.
"So," he asked, "how do you plan to deal with him?"
Belial and Riku both fell silent.
Killing him was out of the question.
Otherwise, Belial would not have spared him earlier.
"Yuzhou-san," Riku finally said sincerely, "do you have a way to send him back to his original universe?"
Even as a parallel counterpart—
He was still someone else's father.
"I do," Yuzhou replied, arms crossed.
"But are you really just going to send him back like this?"
If Tartarus decided to reclaim him later, it would be far too easy.
Yuzhou had no means of preventing interdimensional abduction.
"Come on," Belial snorted.
"Let me teach this reckless brat properly."
Dragging his alternate self, Belial attempted to leave the golden space—
Only to find it sealed.
"Tch."
"Leave it to me," Yuzhou said.
He cancelled his transformation and summoned Charija's Suitcase.
After a brief series of manipulations, he used its spacetime power to tear open the golden independent dimension.
Seeing this, Belial forcibly reverted his alternate self into human form.
The two looked nearly identical—
Except the alternate version was clearly younger.
The four entered the wormhole generated by the suitcase and departed.
Behind them, the golden energy sea roiled violently.
The entire space trembled, on the verge of collapse.
At that moment—
A silver-black arm extended outward.
Golden lightning burst forth, stabilizing the crumbling realm instantly.
"Tiga…"
Tartarus muttered, gazing toward where Yuzhou had vanished.
"You're far stronger than I anticipated."
A dangerous glint flashed in his eyes.
"It seems I'll have to invest… far more effort into dealing with you."
