With no third parties to harm the world, Yuki prepared for this inevitable fight. All his power was unleashed in an instant, and a jet-black exoskeleton rose...
This is how it should have been from the beginning. He should never have let Yuno and Jasmine handle it. This was his fight...
Chaos and Order have waged this eternal war for millions of years. It's time for him to join the battle.
To win, he had to give it his all. There was no turning back now...
He had to become a Champion...
[Susanoo]
The crown in the sky glowed faintly, and the giant Susanoo, the size of a mountain, rose...
"I can't allow the world to suffer more damage... I must end this quickly..."
Inside the Susanoo, Yuki analyzed the situation. The Absolute Crown was incomplete and hadn't yet activated its domain. Without the domain, deflecting attacks from the world caused significant harm to his body. He needed the domain's help to negate this side effect. He was at a total disadvantage at the moment because he had to protect the world...
But...
"Even so, I'm not alone... Let's go, Est, Eggy!"
"Yes!" x2
The door to the spirit world opened, and his two cute spirits fused with the Susanoo.
Eggy embraced Yuki's neck from behind, unleashing her spiritual power...
Great black claws, like mist, formed behind the Susanoo. At the same time, an enormous silver sword materialized in Susanoo's hands.
[Sage Mode!]
Yuki wasn't going to hold back at all. He quickly unleashed his entire arsenal. The mark on his forehead, the Byakugō no In, lit up, and the senjutsu chakra he had stored was released...
The Susanoo grew even larger. An ancient golden clock formed on Yuki's back alongside the Truth-Seeking Balls, and two flintlock pistols materialized in his hands...
[Zafkiel!]
*Tick, tack...
Everything happened so fast that it didn't take even a minute for Yuki to enter his maximum state...
"We have 5 minutes! I can't maintain this transformation for longer! Eggy, I'll leave the defense to you!"
"Leave it to me!"
"Let's go!...[Dalet!]"
*Bang
The sound of a gunshot was heard, and the Susanoo vanished. No, it didn't. It moved at extreme speeds, impossible for the eye to see...
*Shiii
The silver sword cut through the clouds, splitting them in two...
[GAAAAA!]
But this was an attack the beast had anticipated. Its body filled with lightning and moved at a speed that rivaled the Susanoo...
*BOOM
Tentacles and the shining sword clashed, the shockwave sending a devastating blow. The crown protecting the world lit up, nullifying the attack and passing the entire blow to its master...
"Gah!"
"Guh!"
[ACKK!!]
Three painful groans were heard: Yuki from the crown's side effect, Est from clashing with Chaos, and the Beast from the Sword of Order...
*BOOM
Another clash between giants, and again, they groaned in pain...
"Zayin!"
*Bang
Suddenly, the sound of a pistol was heard, and the beast halted. The Susanoo took advantage of the moment and swung the sword down...
*Crackkk...
*BOOM
However, just as it was about to cleave the beast in half, the stopped time around it was corrupted, freeing the beast...
*ROOOAAARRR
The beast couldn't be stopped by the laws of time and space not activated by Order. Both could be corrupted by Chaos. Only Est and the enormous Susanoo could defeat the beast, as both had vast amounts of Order energy, leaving Zafkiel as a speed support.
For the first time, Zafkiel seemed defeated. However, Yuki was still using spiritual power to control time, all the Order energy being used on his Crown. So, he could only rely on Est and Eggy, who had been baptized by Order. This was also why Est could clash with Chaos without being killed...
From the perspective of the world's inhabitants, all they could see was an enormous shining crown clashing against a strange cursed mark.
"Hmph!"
Wiping the blood from his lips, Yuki snorted coldly, seeing the tentacles rise again in the infinite darkness. This monster tried to crush destiny again, this time targeting Est and Eggy. However, at the same time, the Crown lit up and crushed the tentacle in the infinite darkness...
As long as Yuki was alive, it would be impossible for this Overlord to crush the destiny and souls of his spirits. After all, such attacks were useless against him...
*Bam
The enormous misty claws clashed against the tentacles while the Susanoo moved with agility and brought the sword down again...
The beast's tentacles fell and crystallized upon contact with the Apocalypse Virus. However, the strange organism regenerated too quickly, with the tentacle growing back in a blink...
*BOOM
Suddenly, an energy bomb was fired from the beast. The Susanoo twisted its body, and Zafkiel began spinning its needles...
*Bang
"Zayin!"
Time stopped again, and the Susanoo swung the sword, clashing with the energy bomb and causing another explosion...
[GAAAAAA!]
The Truth-Seeking Balls turned into stakes and shot out, piercing the beast, injecting all the Apocalypse Virus Yuki could in that instant. Unfortunately, this only lasted a moment before being corrupted by Chaos.
Even so, the Susanoo didn't cease its attacks. The sword and tentacles clashed, both giants moving at great speed, taking the battle across the continents of Europe and Asia.
*Tick, tack
Zafkiel's hands spun continuously, and the time around was running out, but Yuki still couldn't deliver a decisive blow to the monster.
The Apocalypse Virus was fighting against the strange Organism, while Susanoo and his spirits were being contained by the beast. Zafkiel was powerless against the corruption, and the Crown was protecting the world by nullifying all attacks...
There was only one way...
"Limit between reality and dream!"
The Mangekyou Sharingan spun, and mist began to cover the entire area. Yuki would take this battle to the dream world to alter reality and avoid causing more harm to the world...
[CHAOTIC CONCEPT!!]
However, at the same time the mist formed, a black miasma did too. Both distorted reality and clashed, creating holes in reality and the world's laws...
*Bam
Everything was a disaster. The collision between both powers was devastating...
"That power..."
Yuki opened his mouth in shock. The beast was altering the world's concepts, destroying and creating others to stop the Limit Dojutsu...
But this wasn't the most surprising thing. After all, Yuki recognized this power...
It was a ridiculous power that he had cursed many times for being so broken. Concepts were ingrained in reality and the universe itself. Neither time nor space could stop concepts.
Without the Limit Dojutsu, Yuki would undoubtedly lose this battle.
But it also brought painful memories. That power was too treacherous and belonged to that horrible existence...
"Gyaa!" x2
Unfortunately, Yuki didn't have time to continue analyzing this power, as Est and Eggy's cries woke him. The marks on both girls' pairs were enduring the chaos, and the girls suffered the side effects of being exposed to its attacks...
"Damn it!!"
Yuki's body was a mess. Although the beast hadn't pierced Susanoo's armor, receiving the attacks meant for the world had left him severely injured...
Similarly, Zafkiel's chronometer was running out of time. He had to finish this battle. It was suicide to fight an Overlord in terms of endurance or energy. Both were unlimited...
The manipulation of concepts and the Limit Dojutsu, both ridiculous powers, were causing the greatest disaster...
Chaos and Order fighting for supremacy...
The unlimited and the Absolute...
Destruction vs. protection...
*Biri, biri...
Suddenly, large thunderclaps formed in the sky, and the enormous silver sword absorbed all the power...
"Synchronize..."
Yuki and Est united, and both powers were brought to their full potential...
[Raiton: Senko]
A beam of light shot across the entire world, dividing the clouds and everything in its path....
