Stopping the Beast wasn't easy—but it wasn't impossible either. The most important reason the Yuki from the other timeline failed was because he was alone. Even with thousands of clones, they were powerless and didn't increase his strength.
They all died, and he ended up fighting Reine.
Now everything was different. The Crown could prevent damage to the World, and at the same time, the Requiem was weaker than it had been in the previous timeline.
Even so, defeating it was still difficult. But with Reine, it was no longer impossible. That was why Yuki didn't allow Reine to waste her power—she needed to remain at full strength to endure and weaken the Beast. That was why the help of the first Spirit was crucial...
Because she was the only one who could stop the Chaos within it.
Yuki never once considered fighting the Beast directly. That would have been suicide.
There was a far more convenient way to end all of this—and also the most favorable one.
The moment the Beast stepped through the portal, inside Yuki's spiritual World, Eggy, Est, and Aiwass were already waiting.
The Beast appeared and didn't resist the attack. Reine kept her eyes closed and endured everything she could. The three joined forces to push the Beast toward the Sky Castle, which had begun to tremble the instant the Beast entered. The Beast opened its eyes, control was lost, and it began to struggle—but it was already too late.
"Ahhhhhh!!"
BOOMMMM
[Chaos?... Chaos!! Destroy!!]
The Demon King that had been sealed opened its eyes once more. The energy of Chaos was its sworn enemy. It would never forget it—it was etched into its instincts. As an Avenger, it had to destroy all existing Chaos. It wouldn't stop.
"Huh?"
Suddenly, Est—who was helping send the Beast toward the Sky Castle—trembled. Her body transformed into a Sword that flew straight to the Sky Castle, where a radiant hand grasped it tightly and struck.
BOOMMMM
In a single blow, all the chains of the sky shattered under the Sword's strike...
Creeeakkkk
The Ocarina in Eggy's hands shattered into pieces. She staggered back in shock—her final card to seal the Demon King had been destroyed. Aiwass, meanwhile, remained where he was, watching intently for what would happen next...
"Ahhhhhh!"
Sensing the threat, the Beast's cursed mark glowed. Chaos gathered around it, unleashing a blow toward the radiant Sword aimed at it...
But it was futile.
With the chains broken, another gigantic hand intercepted the attack, creating an explosion massive enough to destroy a star. The Crown protecting Yuki's spiritual World shook violently, catching the Spirits on their Thrones off guard.
The Infinite and the Absolute were clashing once more—at a stellar level of power.
"Emperor... of... time..."
[Chaos... destroy...]
From that single clash, even though the Lord of the Abyss and the Hero of the Void were now only shadows of what they once were and remembered nothing, their instincts told them exactly who they were fighting.
That realization enraged them both, and they attacked again. The Beast immediately called upon its trump card—the weapon that had once been able to face him and kill him.
The Requiem—the Arms Coffin it had corrupted. Now that it obeyed Chaos, it was as lethal as it had been against him.
The Beast didn't understand why it felt such hatred—or why it felt such joy—at the thought of striking its opponent with that Coffin.
It smiled. It was beautiful.
Even with the expression of the dead, it was still the body of Mio Takamiya...
It was like forcing him to taste his own medicine.
But the smile didn't last long.
The Arms Coffin didn't answer its call.
That was impossible. There were no barriers that could block the Arms Coffin. The moment it entered this World, the Requiem had entered as well. That alone should have been enough to stop the Demon King...
And it was right—the Requiem couldn't be blocked by space-time barriers.
But it could be blocked by the Crown.
And by Yuki.
At that moment, Yuki was using the very chains the Requiem had bound him with to keep it trapped in the World of dreams. He refused to let it go, stopping the Coffin even as its darkness corroded his body through the chains. He endured everything to buy time for the Demon King to eliminate the root of all evil...
The Fragment of the Lord of the Abyss that had corrupted its weapon.
Without the Requiem, the Beast panicked in the face of the Demon King's incoming attack. This time, it wasn't just the Demon King's hand that emerged—his weapons followed as well.
Clock
[Activating Incomplete Domain Lucifugus: Upper World...]
A colossal astronomical clock the size of a planet materialized, shielding the spiritual World. At the same time, the Demon King's heavy aura sealed the space around the Beast, preventing it from moving...
A massive amount of Order energy gathered.
Rising from the Throne, a radiant spear appeared in the Demon King's hand, pointed directly at the Beast...
[Destroy... I won... I did it... I destroyed it... I stopped the war... I won... I can't... I can't... lose!!]
All of the Demon King's fury condensed into that spear. He sacrificed everything to kill the evil that had nearly destroyed his World—the evil that had slaughtered thousands of Worlds. He wouldn't allow it to remain free. He would kill it.
[Belphegor: Jerez!!]
Buzzzz
An instant strike.
The spear was so fast that before any light could flash, before the Beast could even feel it, the cursed mark on its body shattered and disintegrated...
Chaos was destroyed.
[I won...]
The Demon King's enormous palms stretched out and seized Mio Takamiya, dragging her into the Sky Castle along with the chains bound to each Throne of the Crown.
The Demon King was reclaiming what was his.
Mio Takamiya.
And the Requiem.
And in the moment Chaos was destroyed, the fading, dying consciousness of the Beast remembered why it had ended up like this—and why it had usurped the power of the Hero of the Void...
There had been no way to stop the Hero of the Void. He had surpassed it in power. The Lord of the Abyss realized that after losing to him and being hunted across the entire multiverse. The Hero of the Void became a champion and gained the power of the Avenger—a Berserker who rose stronger each time.
To avoid being killed, the Lord of the Eternal Abyss split his soul into thousands of fragments across the multiverse. He believed that way the Hero of the Void wouldn't be able to kill him.
He was wrong.
During the long pursuit across the multiverse, the Hero of the Void did the same—splitting his soul and his future into thousands of clones that hunted those fragments and killed them.
Most of those clones succeeded. They launched suicide attacks against each fragment, dying alongside them.
But some fragments managed to escape—like those Yuki encountered in the World of God Eater. Even then, they paid the price. Their power was greatly diminished, and they were badly wounded.
The fragment that fell into this World was the same. But unlike the fragments in God Eater, this one was alone—and it didn't completely escape the Hero of the Void's clone's suicide attack.
They fought.
The Beast was so terrified that it had no choice but to enter this World and use it as a hostage. As a clone, it didn't possess a Crown—and that meant the World itself was in danger.
The Beast succeeded.
And yet, it also failed.
Although it caused tremendous damage to the World of Date A Live, the Hero of the Void nearly killed it. He used his own body to protect the World.
The Hero of the Void's clone would have succeeded in killing it at the cost of his own life—self-destructing like all the other clones.
But [Parallel] didn't allow it.
She saved his life.
She sacrificed herself in his place.
She fell into the World of Date A Live to save him.
And in doing so—
She also saved the Beast.
And that was when everything in this World changed...
