Moscow, Federation War Counsel…

"The battle against the Empire is going well." one of the officials said. "Even with the destruction to our capital, we don't need to worry about the front lines for now."

"Hmm…speaking of the attack, what of Comrade Loria's condition?" the man sitting at the foot of the table asked.

"His condition is severe. Those…animals, managed to wound him just before the point that he could die from his injuries, but still left him in pain." another official said. "That being said…he's recovered enough to send this correspondence." he said, pulling out a transcribed letter.

"Comrades, the attack on our capital cannot go unpunished. It has come to my attention that the mages responsible are holed up at Tiegenhoff. I purpose that we send as many forces as possible to that location to apprehend them, and bring them back to face the judgment of the people. I will personally see to it, once my injuries are healed, that the leader of these terrorists is dealt by myself. Our new allies have already begun preparations to assault the city. Thus, we must do our part to assist them and foster the alliance between us. That is all."

"So Loria has his eyes on that mage girl…" the leader said, some members of the cabinet grimacing at the thought. "Ah well, it doesn't matter. If those demons are going, then the battle is sure to be won. We will follow Comrade Loria's proposal. Prepare all available forces to march."


Meanwhile, in an unknown location…

The sound of screams filled the air as Zenos Road and his Heavenly Kings looked down from a platform at numerous people being tortured at the hands of goblins.

"God, this is a bit much…" Sentibug shivered.

"It is necessary." Zenos Road said. "Pain is a powerful motivator when concerning humans. When push comes to shove…"

The group saw one human be consumed by darkness and transform into an Unversed that killed the goblins that were torturing it.

"They often fall." the Demon Lord finished.

"The weakness of humans…it always disgusts me." Verde scoffed.

"My lord, the Fatebreakers and Reformed Society are stationed in Tiegenhoff." Eraser Kaiser said. "It seems they are attempting to lure us out."

"Are we going to go play, daddy?" Eveline asked.

"...Yes, I believe we will." Zenos Road said. "They think they have the upper hand. But they have forgotten who I am."

A change seemed to overtake the demon lord as his eyes glowed red.

"I am Zenos Road, S-Class Cockroach Demon Lord of Gaeabrande. Usurper of Lucifer Crowe, Dominator of the Warmaster, Slayer of 50 summoned heroes. And I do not show mercy. Prepare for battle!"


The next day, at the first crack of dawn…

Tiegenhoff quickly became the very center of an all out war, as gunfire and explosions echoed across the darkened sky. The Federation used Loria's human wave tactic to full effect, assaulting the city with hordes of ground troops and Eveline's Molded.

"Damn it, where did Evie get all these Molded?!" Kazuma questioned.

"She must have taken them from the battlefields. Plenty of corpses to work with there, I'd say." Gimilor answered.

"And this assault is only going to supply her with more." Toya said. "We'll need to gauge our movements more carefully around these things."

"Yes, exactly. If we take out too many strong soldiers as long as she's around, she'll just bring them back to life and unleash more hell upon us." Kareem said.

"Not if we have divine weapons, she can't!" Ethox said, pulling out the Heartbinder.

"Ethox, no. There's too many of them for Nariko to handle now. We need to wait for the right moment." Rista said.

"O-Oh, good point." Ethox admitted.

"Alright, as of this moment, we are on crowd control." Tanya declared. "Aqua, since you're the one with Purification, you will be making sure the Molded don't make it through our defenses."

"M-Me?" Aqua stammered.

"Yes, you!" Tanya barked. "Reformed Society, your faster members have to get up to the enemy line. Disable their heavy artillery, give our men some breathing room. As for the rest of us…engage the enemy with everything you have! We cannot lose this city!"

"Right!" the group declared as they spread out.


And so, the group fought against the encroaching army with all their might as day turned into night, and the fields were stained red.

18 hours later, Tanya, Viktoriya, Ethox and Cheetah met up at a resupply post where wounded soldiers were being treated as best they could.

"Everyone, resupply quickly! Resupply units, move quickly from one company's supply post to the next!" Viktoriya ordered.

"Get the wounded to the medics, now!" Tanya ordered, noticing Ethox breathing heavily. "Don't get tired now, we have a long road ahead of us."

"Y-Yeah…" the Nobody panted. "I…I'm okay."

"What about you, Cheetah?" Viktoriya asked. "Are you and your team doing alright?"

"There were some minor injuries, but we're managing as best we can." Cheetah said. "Rayleigh is having a feeding frenzy over there."

"Major, this is 02!" Matheus called over the comm. "We have another two enemy divisions approaching from the northeast! And not all of them are human!"

"More Molded?" Tanya asked.

"No, ma'am. Goblins from Goblin Slayer's world." Matheus, shocking Tanya. "They should reach the area within minutes."

"This is 03. We're seeing reinforcements as well." Koenig called in.

"This is 04. Enemy armor sighted at point G2!" Neumann added.

"What is the Federation thinking, throwing all these guys at us?"

"I'm starting to wonder if Communists are grown in fields." Tanya growled. "Anyone from first company who can stand, follow me! We'll destroy the Commies before they reach the area!"


The battle then stretched into 27 hours, as night turned to day once again. The Onslaught of Goblins, Molded and Federation troops did not stop, giving the empire no chance to breathe, but heavy casualties were being suffered on both sides.

"What's everyone's status?" Tanya asked as she continued to fire onto the ground below.

"No major injuries, but everyone's exhausted." Viktoriya said. "Our battalion is running low on ammunition and magic, and everyone else isn't faring much better."

"And this is the perfect time for our targets to strike." Tanya said. "Everyone, stay alert. This is the golden opportunity for Zenos Road and the Four Heavenly Kings to strike!"

"Major, this is 03! We have a problem!" Koenig said. "They made it past our interception net! The multinational unit from Moscow!"

"Mary's unit is here?! Tanya, watch yourself!" Ethox said. "Once they get into the city, there's no doubt about it that Mary will gun straight for me or you!"

"I know! But the rest of them…are they after HQ?!" Tanya realized. "Damn it! Everyone, form up and-!"

It was then that the world seemed to stop, as a massive darkness blanketed the battlefield.

"Having fun, Fatebreakers?" a voice said as Zenos Road appeared before them, floating in the air.

"Zenos Road!" Ethox realized.

"Today is the day this all ends. Your hopes, your dreams, your very lives…they will cease to exist on this battlefield." Zenos stated. "Let your final moments be ones of horror."

"Major! The Heavenly Kings have been confirmed on the battlefield! Verde has been sighted!" Matheus said.

"We've got Eraser Kaiser bearing down on us from Point G2!"

"This is 03! Eveline's heading for the outposts! She's after the wounded!"

"Sentibug spotted! She's following those enemy mages!"

"Divide and conquer, I think you call it? It's working quite well, as you can see." Zenos Road said. "But wait, there's more! Would you like to say hello…to the Federation mages?"

With a wave of his hand, Zenos opened portals all across the battlefield, numerous Heartless and Unversed crawling out of them and decimating the Imperial soldiers.

"Unversed? And Heartless?" Ethox realized in shock. "You…you turned all the mages in Russia into…?"

"Some gave themselves to Being X to escape their torment. Others were consumed by hatred for their country, their government, or mankind in general." Zenos said. "Either way, it all led to the same fate: serving me."

Tanya floated there as she watched the Empire's forces being overrun.

"Tanya, your orders! Tanya, tell us what to do!" Valfor said.

Tanya was not weak willed. As long as the group had known her, she had managed to keep herself mostly in check emotionally. But everyone has a breaking point. No one can keep themselves like that forever. And Tanya…had reached her limit.

She screamed in frustration and rage as she fired her rifle onto Zenos Road, only for the Demon Lord to block her shots with little effort.

"Evil Eye…Omega." Zenos Road said, his eyes glowing red as the group members facing him were unable to move. "Let's watch your teammates die, shall we?"

(Cue- Requiem- Bayonetta 3)

Zenos Road floated to the ground, taking his prisoners with him, as he landed where Ethox was fighting, before being knocked to the ground by a Heavy Heartless.

"I think we'll start by watching the Nobody perish." Zenos Road decided.

"T-Tanya…" Ethox said, reaching up to them, before Zenos stomped on his foot. All across the battlefield, the group members were hard pressed to defend themselves from the overwhelming odds.

"Do you understand now? How futile your efforts were?" Zenos asked as he picked Ethox up by the arm. "I have lost my world…so I will take this one in exchange. I must say…every hero I've faced before you…it was never personal. None of them ever caused me as much trouble as you. So, believe me when I say that: what I'm going to do to you and your friends…I'm going to enjoy it."

Zenos was about to lay the finishing blow before a barrage of bullets fired at him. This broke his grip on Ethox and his hold on the others with his evil eye Omega.

"What…?! Who dares…?!" Zenos yelled, before he saw numerous portals around the battlefield, not opened by him. "What is this…?"

(Music Shift: Portals - Avenger's Endgame)

Stepping out of one of the portals was Simon Neptune revealed to be the one who fired as he walked over to Ethox and sat him up.

"You didn't cry while I was gone did you?" Simon asked with a smirk.

"What the heck took you so long?" Ethox asked, his hopes rising.

"Well it took a while, but I managed to gather everyone you asked for." Simon said.

"What… you mean…?!" Zenos Road asked as Tanya smirked.

"The arrogance of Gods and Demons. You honestly thought I was shooting at you in complete anger?" Tanya asked. "That was all just an act. A signal for everyone else to gather."

"No… you tricked me again?! That can't be possible!"

But it was, as out came from the portals came all the allies the Fatebreakers made during their adventures as part of Mythos Hearts.

Johnny, Mr. B and Sally appeared, accompanied by Kat and Dusty, alongside the forces of the Sorcerer Kingdom Ainz Ooal Gown.

Shirou Ogami and Chris Redfield appeared from another portal on their own. There was no need for others from their worlds to join the fight; they would be enough.

Wiz and Vanir stepped out from another, followed behind by the adventurers of Axel's guild.

From the fields of Mordor, the Gravewalker's army marched forth, ready to ravage the enemies presented to them.

From another portal, there came Master Shen and the entirety of the Tiāntáng de Púrén tribe, alongside them were Mayday and Zuke.

Another portal revealed Noble Fencer and all the members of Goblin Slayer's guild.

Next came the leaders of Fodlan, with Yuri, Byleth and Shez, accompanied by the foot soldiers of the Adrestian Empire, Kingdom of Faerghus, and the Leicester Alliance.

From above them, a green dragon flew into the field of battle before it landed, Rosalie and Elulu dropping from his back as he reverted back to Mash, the force of Tempest coming with them with said slime leading them into battle.

And finally, the rest of Mythos Hearts came through the other portals to reinforce all the points besieged by Zenos's forces. The Demon Lord himself, his Heavenly Kings, and even William, Vivi, Mary and the entire multinational mage unit couldn't believe it.

"Is that everyone?" Theo asked.

"What, you wanted more?" Simon asked.

"This… this is impossible! How can one single guild… have gathered this massive army!?" Zenos said. "How are you able to bring so many people together?! Tell me, Theo Starcrest!"

"You brought this all down on yourself. Like Luffy said back on Onigashima…we're taking all of you down. Kaido, Big Mom and Tormal already fell. You're the last one!" Theo said.

Zenos Road looked at the army brought forth to challenge him, falling silent before he spoke. "...Very well then. Then by all means…"

Zenos raised his hand to the sky. "...Try and kill us!" he finshed, snapping his fingers before his forces turned upon the newcomers.

Mary, likewise, gritted her teeth and prepared to rocket towards the battle. And in that moment, the unified army under Mythos Hearts prepared to attack.

"Mythos Hearts…!" Ethox yelled out, reinvigorated by the arrival of his friends. "...Let's break fate!"

"ATTACK!" Mirror Match shouted, the cry being echoed across the battlefield as the united army charged towards the monsters before them. The Federation army responded in kind, charging on all fronts again, backed by Eveline's molded, Verde's goblin horde, and the armada of Heartless and Unversed.

On that command, Mary screamed at the top of her lungs as her mage unit went to full power and blasted towards the battle.

"Mary, wait!" Vivi called out.

"Dammit, Warrant Officer Sue, stay in your two-man call!" William ordered. "In a situation like this, we need to stay together!"

"I'm fine! I can do this!" Mary responded, charging forth.

It wasn't long before both of the massive armies clashed, the battle truly beginning. Mythos Hearts and their combined might combated the united Federation and monster armies, as the area outside Tiegenhoff became an all-out war zone. Zenos Road was so distracted by his perfect scene becoming undone, that he failed to notice Seiya crashing into him too late, as both of them were driven further away from the city and to a safe place to duke it out.

"About time I got you all to myself." Seiya said as he stood up.

"Seiya Ryuuguuin." Zenos Road sneered as he got up. "Was this another one of your insane plans?"

"Why are you asking? Of course we were going to call for help. We're not stupid enough to try and take on a whole army on our own." Seiya scoffed.

"No, you are not." Zenos Road agreed. "But the battle between armies matters little. We're going to finish this the classic way?"

"It was my job all this time. The Chosen hero's supposed to take down the Demon Lord, right?" Seiya said, drawing two Platinum Sword Plus'. "It's time we wrapped up this years long RPG quest."

Zenos tossed off his cape as he transformed into a larger, more demonic looking form with scales covering his body, horns, and red eyes. He also had six arms, all having large, sharp claws attached to them. "I couldn't agree more."

"For the last time…I'm perfectly prepared." Seiya said. "I'm 100% ready for this."


(Cue- Vessels Emerge- KH3 Re:Mind)

At the point where Verde's army was attacking, his goblin horde was being decimated by Noble Fencer and Goblin Slayers guild alongside his party. Verde tried to enter the battle himself, going for Noble Fencer, but Goblin Slayer stood in his way… the very man who killed him before.

"Slayer…" Verde seethed, as he held his black sword at the ready.

"This time when it's all over… you're going to stay dead"." Goblin Slayer declared, drawing his sword, his machine Hook in his shield arm as his eye glowed through his helmet visor.

"No more games, Slayer. To the death!" Verde declared. "And may the best warrior prevail!"

"...Sure." Goblin Slayer responded as the two charged.


With Aqua, she was busy blasting molded left and right with as many Turn Undeads as possible, Chris and Shiro having joined her side.

"Damn it, my Ramrods are almost useless now!" Chris said as he punched a Molded that had gotten too close. "You're saying they're demons now?"

"Yeah! Only divine power can kill them!" Aqua said.

"But they will just keep coming. Is there a way to permanently kill them at the source?" Ogami asked in beast form as he was ripping them apart.

"Yeah… by killing her!" Aqua said as Eveline appeared, and she didn't look happy.

"Daddy was about to win, and you all had to go and mess it up!" Eveline pouted. "I'm gonna need to get a lot more playmates to deal with them. And I think I'll start with you three!"

A wave of mold crashed its way to the three of them, Ogami and Chris able to get out of the way in time, but Aqua screamed as it almost crashed on her. She would've been infected if not for Kazuma tackling her out of the way just in time, joined by Megumin and Darkness.

"Kazuma!" Aqua cried in relief.

"Nobody bullies you but me!" Kazuma said, standing back up and looking at Eveline. "So…you looking for a big brother to play with, huh? How about I fill the part for ya!" he declared, pointing his sword at her.

"Back to the vile pits from where you came, Eveline!" Darkness agreed, drawing her sword.

"This time we'll obliterate you so there's nothing left to come back from!" Megumin chipped in, raising her staff.

"You can't win." Eveline said. "I'm better than you."

"Oh, I actually feel pretty good about our odds." Kazuma said. "After all…we've got a goddess with us!"

The otaku turned to Aqua, who looked shocked by his words. "Let's do this, partner!"

"...Leave it to me!" she responded in joy as the two shared a thumbs up.

"This is gonna be such a fun playdate… I'll play with you all until you break!" the bioweapon turned demon said maliciously.


"Damn it, this is not going as planned!" Sentibug said to herself as she ran through the streets of Tiegenhoff. "I have to summon more Unversed. Should be enough emotional distress with the wounded. Gotta find the medical tent…"

"Not so fast!" a voice called as crystal walls were erected, blocking Sentibug's path. She looked behind her to see Michiru, along with all the former members of the Anarchy Kings confronting her.

"No more running away, Sentibug." Mirror Match said. "You are the last remaining remnant of Ehto's army of darkness. We let you escape in the Underworld. It's time you and all the emotions you were made from be put to rest."

"I don't have time for this crap!" Sentibug said as she tried to swing up with her yo-yo, but was cut off by Michiru.

"Didn't you hear him? You're not getting away." the Beastman said.

"Oh…so that's how it is." Sentibug said. "Just cause I was born from emotion, you don't think I'm a real person? Fine…I'll just have to show you how real I am!" she said, summoning the Unversed.

"It doesn't matter where you came from, or if you're real or not…you've caused enough trouble!" Michiru said, forming her gorilla arms. "I'm no warrior of light…but I'm not going to let you get away again!"

The two girls stared each other down before they both, along with the other Anarchy Kings, charged in.


"I wish we could help the major and Ethox with that enemy mage after them…but it looks like we've got our own problems." Viktoriya said as the 302nd and Reformed Society were face to face with Eraser Kaiser.

"So, you're the ones sent to challenge me?" Kaiser asked, each of his six arms holding a weapon.

"And you're the one called Eraser Kaiser, are you not?" Nesma asked.

"Yes. Lead general of Zenos Road's army, slayer of 35 summoned heroes, bane of Gaeabrande." Kaiser said. "Before we begin…do any of you have any last words?"

"None that you would understand." Cheetah said.

"Except these: These won't be our last words." Grantz added.

"How confident." Eraser Kaiser remarked as he brandished his weapons. "With all that out of the way…let us commence your deaths!"


Mary rocketed towards Tanya and Ethox before he could even decide to help out Seiya.

"Here she comes!" Ethox said. "Ready Tanya?"

"As ready as I can be, given the situation." the young child said. "What about you?"

"...Same." Ethox said. "I'm not sure what will happen next…but it won't end happily."

The two stood ready as Mary leveled her rifle at them, firing as the two avoided the spells.

"Mary Sioux!" Ethox yelled. "I failed to save your father…and I can't save you either! So the only option I have is to end your suffering forever. I'll send you to your father on the other side!"

"I'll kill you!" Mary snarled as she raced towards the Nobody.

"Let's get this done quickly. We have a battle to win." Tanya remarked.
