Brazil:

No Primordial and no Monarch emerged from the Gate in Brazil. It was limited to just the forces of Yogumunt. They were by far the weakest army of the Monarchs in terms of sheer magic and physicality, and as such, no humans were sent to guard Brazil. Instead, only one Shadow was sent to repel the invaders. That one Shadow was already standing with a million of its brethren.

Because of the heavy limitations and weakness of the Shadow Twice, Izuku couldn't use him to duplicate his own forces. At most, Twice could duplicate a single Shadow at his level, but no matter how many duplicates of himself he made, he wouldn't be able to make any clone other than himself. These heavy limitations had kept the Shadow at a very tame grading of Captain.

When Bellion appeared and removed the Shadow Save Limit, Izuku figured that Twice would thus be able to endlessly duplicate and form an army of himself. If Izuku buffed him to the level of Marshal, it would be invaluable. However, as he began experimenting, he realized that Twice duplicated himself using some of his own Mana. Because the clones didn't have a regen function, they didn't need much Mana to be created, but they were far too weak to handle even a single Knight Grade Shadow once they started splitting enough. And since they did require Mana, there was indeed a limit.

Basically, against the far more powerful forces of the Monarchs, Twice and his own army would just get in the way. So, Izuku decided to utilize him by sending him to Brazil, to continually replicate himself and delay the forces of Yogumunt.

It was pathetic how easily each clone fell, but with several more to step up to take the fallen's place, Brazil was being defended for now.

China:

Nemesis roared at the top of her lungs as she dove forwards, using her immense weight to tackle the Primordial of Titans to the streets of the city. She pinned the Kaiju-sized giant to the floor as her trident-tipped tail shot down from over her shoulder, aiming to spear the Primordial through the head.

But just before the dangerously sharp instrument could lurch forwards however, a sort of rainbow slime looped around the tail, halting it in place.

Nemesis growled, instead choosing to dig her claws into the Titans flesh, completely ignoring the Primordial of Flowing Shape behind her. The Titan could do nothing as his limbs and torso were sheared away at. All the while, Nemesis paid no mind to the corrosive slime eating away at her own body. She left it to Barbatos, who burned away at the adversary with his immortal flames.

While the Primordials raged like the monsters they were, Bellion danced between the Monarchs, Centillion whipping around faster than the speed of sound.

Yogumunt's knives moved just as fast, deflecting each blow with the force of a shotgun blast and Legia's fists slammed down hard enough to create mini-earthquakes.

Every now and again, Centillion would get close, nicking Yogumunt and carving a wound in her side. Unfortunately, it was healed just a moment later. And without the proper force behind Centillion, which Bellion couldn't muster while fending off both, he couldn't break Legia's skin.

"Let's end this!" Yogumunt cried with glee as her mortal body began burning away, replaced with a heavily muscled woman, seemingly made out of nothing more than energy. Four extra arms, wielding even more blades, popped out of her body, forming her Spiritual Manifestation.

Legia did the same, cracks forming in his stony skin as bright light raced up his body. The light almost looked like molten rock moving through him as his skin became harder and brighter, becoming almost reflective as they took on the sheen of diamonds.

Yogumunt began moving at a blur, the Spiritual Essence she had built up over the past three years bursting forth as she swiped with killing intent.

It became so bad that Bellion had to retract Centillion in order to defend himself from the rapid blows. But even that wasn't enough as Legia's fists crashed down around him, restricting his movements even further.

In a moment, everything went wrong. Yogumunt's blades slashed open Bellion's skin, pouring in Mana to restrict his regeneration. At the same time, Legia's massive fist went to crush the Shadow.

Bellion was caught in the middle of a backstep, one that Legia had predicted. He wouldn't be able to dodge the attack. And to be stuck underneath it would mean his true and permanent death as the Monarch's used their Mana to errode his very being.

There were no other Shadows strong enough to help Bellion and they were all occupied with the insect forces regardless. And even still, Bellion didn't falter, no fear crossed his face, because he could feel his Liege's energy.

Just before Legia's fist could complete its fall, a clawed fist burst forth from the giant's chest, clutching both his heart and his Spiritual Essence.

Izuku, still in his Shadow Form, clenched his fist, crushing both the heart and Spiritual Essence, enveloping them both in his Shadow energy. "Sorry Legia. I didn't mean to take so long."

Legia fell to his knees, strength quickly leaving him. The rage in his animalistic eyes faded for just a moment and Izuku could've sworn he heard a,"Thank you," Escape the Monarch's mouth as his Spiritual Essence was taken over and destroyed.

[You have killed one of the Nine Monarchs, The Monarch of Giants, Legia]

At that very moment, Izuku's second Divine Weapon Trigger faded and the Shadows surrounding his body collapsed, dropping him back to his feet and normal height.

With Legia out of the picture, Bellion was free to assign his full focus to Yogumunt. Up until this moment, he had been holding back his true power so he could release it all when his Liege returned.

Casting aside all of the defensiveness Bellion had shown moments earlier, he charged Yogumunt, Centillion flashing as Yogumunt was pushed back. With immense precision, Bellion's blade and fist flashed, disarming the Monarch one by one. He lopped off arm after arm, continuing even after they were regenerated to burn away her Spiritual Manifestation.

Izuku slashed his claws through the air, generating eight blades of darkness that cut her up into ribbons.

She desperately tried to put herself back together as her Manifestation began to fade.

"Divine Weapon Trigger." Bellion spoke calmly, thrusting forwards with Centillion.

[Centillion Divine Weapon Trigger: Death's Cocoon.]

Centillion expanded past what should've been possible, forming an impenetrable cocoon around the Monarch of Transfiguration. She attempted to claw her way past it, but the spinning blades sheared away at her body. She couldn't escape, even as the enveloping blades closed into a ball, compressing and blending her body into nothing.

When the darkness cleared, only Yogumunt's corrupted red Spiritual Body was left. It tried to run, but Izuku reached out, Shadow Supremacy grasping at the cloud of dust, burrowing into it and painfully eating it away, bit by bit.

Just before she could completely be consumed, Izuku left her with a final message, "You shouldn't have come after my family."

[You have killed one of the Nine Monarchs, The Monarch of Transfiguration, Yogumunt.]

Izuku looked back to the millions of insects still pouring from the Gate. The same could be seen around the world. No matter how hard they fought, it seemed like there were just too many. Even if all the Monarchs were killed it would be a struggle to preserve the world.

"Let's even this out." Izuku raised his hand to the air, "Final Divine Trigger."

[Armor of the King's Final Divine Weapon Trigger: Call of the Shadows.]

"Arise." All around the world, the dead heeded the call of their Monarch.

Russia:

Magic forces filled the air, giving humanity a show like no other it had ever witnessed.

Iruit wasted no time manifesting his Spiritual Form. Four of the Monarchs were dead, this was no time to be hesitant.

His shadowy body morphed into a complete blizzard, a body made of ice forming in the center. Cruelty decorated his face as he swiped his arms, spreading his influence across the forces of Izuku and humanity. Entire swaths of the army were turned to ice. They were not encased in it, but quite literally converted to it. The attack reached far and wide, in some cases only catching limbs or heads. Immediately, the frozen part would fall off, leaving the victim weakened in front of the Monarch's minions. If the Shadow Healers were quick enough, they could recover the lost mass, but they rarely were in time.

The Shadows, as usual, were nonplussed, allowing their limbs to fall away and come back. The weaker ones, those entirely turned to ice, shattered, never to return to serve their Liege.

Iruit laughed, swiping his arms again. But this time, the sheer cold was directed upwards, with no target. He scowled and looked around, finding Hyo, wielding his ice-enhancing daggers. Angelic Shadow wings hugged his back as he hovered next to Azrael and Tusk.

[Transfiguration Magic: Angel's Blessing.]

Azrael's tome hung open, gifting Hyo and Tusk their wings. Tusk's were six pairs of demon wings, beating in rhythm to keep him perfectly steady as he conjured his own magic.

[Ultimate Fire Magic: Solar Storm]

"No!" Iruit shouted, casting a hail of perfectly blue ice at the three Shadows.

Hyo crossed his daggers. He could not stop the Monarch's attack or even redirect it, Iruit was now too focused to allow a mere Marshal Grade to hinder him. All Hyo could do was slightly weaken the ice, pulling mass from it and slowing it ever so much.

At the same time, Tusk's attack, boosted by Azrael shot forth, illuminating the snowy mountains with such heat that it burned away the snow for hundreds of feet around.

The magic was an attack he devised from examining the memories his Liege had of fighting Razar. Because all of the Shadows could see through their Liege as he saw through them, he had witnessed the fight. As such, the magic's power matched that of the sun, so even as a Marshal it was strong. Boosted by a Grand-Marshal, it was even more powerful.

Of course, no Monarch in their Spiritual Form could be taken down by a mere three Shadows. The attacks collided with such force and such opposing temperatures that the area exploded with steam, obscuring everyone's view of the battle.

Not even Momo could see into it unless she focused her senses, but she didn't try. After all, it wasn't her job to take down this Monarch. That responsibility laid with the Soldier hiding in wait in her Shadow. And it was time for that Shadow… to show itself.

The ice and solar fire were at an unsteady balance, ebbing back and forth as Tusk and Iruit fought for dominance with their elements.

"You're strong!" Iruit shouted, his own body rocked by the intense winds, "But no Shadow will ever beat me!"

"Are you truly certain of that?" A voice said directly behind Iruit. He had been so distracted by the battle and his vision hidden by the steam that he failed to notice Kamish pushing through the bitter cold to emerge just to the side of the Monarch.

[Kamish is using Skill: Undying Flame.]

"N-"

The Primordial flames of the strongest Dragon enveloped Iruit, turning his icy body to a fine mist, then steam, then nothing remained. Even his Spiritual Essence had been snuffed out in that single attack.

"Never underestimate the trust our Liege puts in us."

The war did not stop there however, as more and more forces continued to pour from the Gate, alongside that of a Primordial. A giant ant made completely of ice. Being a true Primordial, it would be next to impossible to vanquish as quickly as the Monarch of Frost, still, they had no other choice but to exterminate it.

At that moment, however, things became far and away easier as a second, slightly smaller Gate, popped into existence. From it, emerged the forces of America. A giant Shadow snake made of smoking fire burst forth alongside Apophis, tackling the ant Primordial to the ground.

Shadows and humans poured out for a solid minute before the Gate closed behind them, leaving America undefended. Or so it would seem.

"Thomas!" Momo shouted to the giant, "What-"

He greeted her with grim certainty as they both continued to mow down hoards of Villains, "Ryukyu's handling it… all of it."

Momo pursed her lips, "So… she never intended to win…"

"I guess not…"

Germany:

"Hehe… He was an interesting prey," Stellian cackled as Mirio's heart laid limp in his hand, spilling red all around, "He never knew that by using Mana, I could find the same frequency he was shifting into in order to avoid my attacks. It's a shame such a method isn't easier to use… being intangible would make any Monarch damn near invincible. But…" Stellian's fingers clenched, crushing the heart into red paste, "Prey wouldn't be fun to hunt if it were easy!"

Lucifer, still carrying Igris, was faced with an impossible choice. With Mirio seemingly dead, Igris was currently the only fighter present capable of bringing down Stellian. All the Primordials were preoccupied and their Liege was currently jumping to America in order to handle the Primordial that Baran brought with him. He either had to carry Igris to safety, likely getting killed in the process, or stay and fight to give Igris time to recover, also likely getting killed in the process.

For Lucifer, it was not an issue of surviving, rather that of success. No Shadow feared Death, they had already returned from it once and been given a second chance. A Shadow only feared letting down their Liege. So, Lucifer chose a third option.

"My Liege, we request… 'that.'" Lucifer's thoughts were broadcasted to Izuku as he fused the Six Dragons together.

"Granted." Izuku replied, barely given enough time to assess the situation as he returned to China to fight off his own two Monarchs.

Lucifer let go of the Genesis Blade, allowing it to float beside him as he clasped hands with Igris. Their Shadows began melding and melting together, creating something new.

[Celestial Spearman, Lucifer Grand-Marshal Grade and Knight King, Igris Grand-Marshal Grade have fused to create Celestial King, Azathoth Primordial Grade.]

Igris's armor and Lucifer's angelic body merged. White accents filled their body, six powerful wings decorated their back, and overlapping plates of exquisite armor covered their arms. Finally the three Divine Weapons had chosen to merge together alongside their wielders, forming a clean blade, seemingly made entirely of crystal.

[Divine Weapon: Celestial Excalibur.]

Stellian was not impressed, choosing instead to let his Spiritual Manifestation cover his body, "No prey escapes me."

"We'll see about that!" Another voice said behind him.

The Monarch, shocked that any other being would even try to fight him, turned, finding a second Spiritual Manifestation on the battlefield. Mirio's body was covered in pure white armor, wings floating behind him as his face was burned away, revealing a being of pure light. But not all was well. At his chest, there was a gaping hole, filled with even more light.

Stellian, having grown larger and his steel skin grown thicker, laughed, "Foolish prey! I tore apart your heart! Once that Spiritual Manifestation fades, you'll die!"

"Maybe," Mirio's voice warbled through the divine filter, "But a Hero doesn't give up just because his own life is on the line! My fate is up in the air, but yours is sealed." Feathers fell from his wings, landing in hands and turning into two massive broadswords. At the same time, Azathoth readied his blade.

Stellian grinned, insanity in his eyes, "Come then, prey. Show me your blood."
