"Where are you looking?!"
In the next instant, the 'Alien God' was right in front of Morgan. A luminous hand rose and swung down at her.
A strike delivered with absolute confidence, certain it would kill this strange enemy—
Morgan raised her magic spear and blocked it head-on. Hand met shaft, and the collision of Mana burst into a violent flash.
"Of course I'm watching you," Morgan answered evenly.
"What… are you?" The 'Alien God' glared, anger spilling into her eyes as she still failed to grasp what had happened. "Where did that man go?"
"He's right here," Morgan said. "Fighting you with me."
There was no time to think, no need to judge. As if carved into her body itself, a fighting instinct took over. Morgan wielded the magic spear with a proficiency that exceeded even her own understanding, driving back the 'Alien God' as she surged in again.
"This… power?" The 'Alien God' stared in shock. "A mere fairy can match me?"
"A fairy? No, that's not it."
Morgan opened her arms with elegant composure and looked straight at the 'Alien God.'
"I am no longer a fairy. What stands before you is an existence fused with the power of the newborn human-god Tehom, united as one. My name is the 'God of Unity, Morgan.'"
"'God of Unity'…?"
Only then did the 'Alien God' understand.
Tenkei Shiomi had not vanished. He had entrusted everything to Morgan, merged with her, and become a stronger form.
While the 'Alien God' was still reeling, Morgan had already sent withdrawal orders to Scáthach inside the palace, and to Storm Border as well.
"We can't let them realize what we're doing. Hold her here," Shiomi said.
Morgan gave a short nod and raised her hand, palm aimed at the gravitational field.
In barely over a minute, rubble from the Orbital Grand Temple was already lifting into the air, forming a trail of ruins that stretched into the black hole—only to be ground down into dust too fine to see.
"Contract. Stop."
Words like an order rang out, and the gravitational field shuddered under Morgan's interference.
For her, erasing that field was something she could grasp in theory but could not accomplish by strength alone.
Even if she understood the mechanism, she was not a god—she could not wield Authority to meaningfully interfere.
But now, supported by Shiomi's complete trust, she could exercise Authority as a god.
And it was not without a cost.
Morgan understood perfectly: in this moment, neither of them had any defenses.
Whichever soul held the higher rank could easily seize everything from the other.
No wonder Shiomi had asked if she still trusted him.
He had never intended to harm her, yet he still worried she might fear that possibility.
And the same was true in reverse.
With Shiomi completely unguarded, Morgan could have claimed divine Authority for herself with ease.
But how could that ever matter compared to him?
When her ideals could not coexist with him, she had been willing to abandon those ideals.
So Morgan kept her calm and invoked Authority, intent on dispersing the 'Alien God's' gravitational field.
Without the Fantasy Tree, the Lostbelt's disappearance was only a matter of time.
But first, they had to buy their companions enough time to retreat.
"Boil."
The 'Alien God' clearly had no intention of letting Morgan erase the gravitational field. Though the black hole had already been completed and no longer required further manipulation, she moved to seize control over it again.
The black hole, which had begun to contract, halted once more. It froze in a fixed state—unable to expand, unable to shrink.
"Good. We've got her attention… Master should already be leading everyone out," Shiomi said.
Morgan shook her head.
"Not enough. Don't you think she still looks far too composed?"
"You're right. Then let's put a little more pressure on the 'Alien God.'"
As she wrestled for control of the black hole and was gradually drawn into their rhythm, the 'Alien God' suddenly saw Morgan raise her other hand.
Countless azure magic spears manifested in the void, all aimed at her.
Caught off guard, the 'Alien God' had no choice but to counter. Though her precision in contesting control over the black hole did not waver, the added assault left her no room to spare attention elsewhere.
A fierce battle erupted in the skies above the detached palace of the Grand Temple.
The Alien Apostles attempted to pursue, but a single attack casually cast by Morgan severed their path.
"She's getting a little heated," Kirei Kotomine remarked calmly.
"If this continues, she may resort to her final measure to end it," the young scholar added. "Nameless has already withdrawn."
"Then we should withdraw as well. We'll consider the rest afterward." Kirei glanced toward the crystalline mountain range. "If something like that explodes nearby, I wouldn't be confident of surviving either."
Taking advantage of the chaos between the 'Alien God' and the 'God of Unity,' the Alien Apostles retreated from the interstellar city—and from the Lostbelt itself.
The black hole shrank steadily during the struggle until it compressed into a single point and vanished into the void.
The gravitational pull that had been devouring the entire interstellar mountain range finally disappeared.
Morgan ceased her barrage of magic spears, preparing to unleash a Noble Phantasm to severely wound the 'Alien God' before withdrawing.
Killing the 'Alien God' was no simple task. On that point, Morgan and Shiomi were in complete agreement.
The Lostbelt itself was already showing signs of collapse.
Dragging the battle out any longer would only make matters worse.
Storm Border had successfully retrieved everyone—including Melusine.
"You can have the black hole," the 'Alien God' declared coldly, chin raised. "As praise for your struggle, I'll let you perish alongside this Lostbelt."
"She—" Shiomi realized at once.
"—plans to detonate the crystalline mountain range's Mana?" Morgan's eyes widened.
But she quickly understood.
As the holder of a Beast's Spirit Origin, the Beast's signature ability, 'Independent Manifestation,' would be trivial to use.
Escaping in the midst of an explosion would be effortless.
Both of them felt a sudden, quiet relief that they had not chosen to fight to the bitter end. If they had forced this move out prematurely, Chaldea would truly have been on the brink of annihilation.
"Heh… hehehe… ahahahahaha!"
With a mad laugh, the crystalline mountain range ignited under U-Olga Marie's will. The Mana within destabilized at once, turning the entire formation into a colossal bomb.
"For my first battle upon arriving on this planet, to face opponents like you—how delightful! Far more delightful than exterminating weak, insignificant humans! I doubt I'll ever forget you! Probably!"
Laughing brazenly, the 'Alien God' U-Olga Marie turned within a blaze of light and departed from this Lostbelt.
The crystalline mountain range, storing nearly inexhaustible Mana, reached its critical point.
