"Cross-Dimensional Observation System No. XX."

"What?" Rosalina have no idea.

"I am a machine originally designed by a vampire named Clavis Alucard for new possibilities, intended for cross-dimensional observation." System No. XX explained. "However, I was flawed to a sudden fault, and ended up invading the worlds I observed and using them as power bases."

"So to prevent me from destroying worlds to create new ones, he sealed me away using the Keystones of the four selected universes." System No. XX continued. "However, his daughter, Rachel Alucard, unintentionally unsealed me and let machine summon warriors from the four selected worlds and having them fight in the Cross Tag tournament, or as I call it: the Keystone Scramble Tag tournament."

"I've never even met any of them." Rosalina responded. "They are unknown to me."

"Rachel went to undo her mistake by having the fighters I summoned... beat me and each other in the tournaments, shutting me down as a whole." System No. XX continued. "Then, thing gets complicated from there, because of a certain warrior." *referring to Hazama*

"Oh, I see." Rosalina understood. "Do you have any hope?"

"To Ragna the Bloodedge." System No. XX bluntly replied. "And ever since the destruction of Reality Zero, I suddenly got to see so many more worlds outside of my original observation, all at once."

"Then things get complicated?" Rosalina asked.

"Yes." System No. XX confirmed.

"Sparks bless you all..." Rosalina mumbled.

An explosion can be heard here.

"There they are! They're coming!" System No. XX noticed.

Meanwhile...

"At this point, we got our power drained back, so we can't break out." Ren Fuji suspected.

"Damn Prometheus!" Magsarion shouted.

"Look, it's the Hegemony Gods and more!" Access noticed.

"You're here to save us!?" Kouha asked.

"Yes." Angela then broke the cages and untied everyone.

"Yes! Our power is free and recovering!" Mitra recovered.

"I'm Angela, Manager Assistant and Library Director." Angela introduced herself. "So this was the Library I have had in, but repurposed by Empress Zero."

"I'm Raiden. Jack might be lurking behind." Raiden introduced himself. "Aside from Angela, there's Carmen, Ayin, Roland, the Rabbids, and-"

"The Sephirot!" Tiphereth shouted. "Here just in time."

"Hello... Who are you?" Rosalina Rabbid saw it.

"Some of you are the fused Rabbids?" Jumpson asked.

"And Edge. With EDGE." Edge appeared as well. "Nice to meet you, strangers."

"All right, that's a mission for Captain Velvet Meteor!" Velvet Meteor stood up.

"Finally!" Gohan stood up. "Thanks for freeing us all."

"You're welcome." Carmen responded. "And we've got a crystal. The alliance got eight so far."

"Let's join the alliance." Angela decided to join.

Meanwhile, in the warzone...

"All those body piled up." ShishiRed looked around. "This is all bloody, as suspected."

The mecha Gattais and the Megazords is stepping on top of the blood-splattered warzone.

"We shrugged of a war." GokaiRed commented. "I wonder what's next."

"Hey you!" A pilot is shouting.

"What?" The Sentais and the Rangers looked around.

It was Mazinger Z, piloted by Ryo Nagare, and a Gundam RX-78-2, piloted by Ray Amuro.

"We will help!" Ryo Nagare told everyone.

"Yeah, they're coming!" Ray Amuro warned.

Indeed, a Sideways Rift be appeared in the sky, emerging several mechas and robots of varying sizes from several worlds, all interacted the multiverses inside the Endless Frontier (i.e. Super Robot Wars franchise). Gunbuster was among them as well, also once again carrying the sword-statue from the Tilted Ruins.

"Operation: Zero!" Simon the Digger and Viral with Gurren Lagann shouted.

"What are we waiting for!?" The robots and pilots are determined. "Let's go!"

"Yes! Go!" All Sentais and Rangers shouted.

All mechas, Gattais and Megazords (even Mega Megazords) then flew to Sideways Rift.

Meanwhile...

"By the way, the cell opposite of me has Kusumi-no-Okami and Rachel." System No. XX noted. "The former is more commonly known as Marie of Izanami, the same name as Margueritte Breuil."

"Huh?" Both Marie/Izanami and Rachel woke up.

"I am Rosalina." Rosalina introduced herself. "Comet Observatory is my current home."

"Break the fog!" Jumpson and Velvet Meteor broke out and onto the cells.

"Someone's there!" Anya noticed.

"That's System No. XX and others!" Ren Fuji recognized.

"It's you!" Kouha recognized System No. XX.

System No. XX is appearing as an beautiful adult woman, with gradient eyes (blue, yellow, purple, red), long white hair with highlights and inner of the same coloring, and wearing silver hooded shirt and skirts incorporating black engravings and polygons (mainly diamonds), and same color scheme plus metallic accents, and transparent bodystocking underneath.

"You're so beautiful!" Gohan drooled over System No. XX, much to everyone else's disgust.

"Bruh..." Roland facepalmed.

"Oops, sorry..." Gohan apologized.

"You forgot who Ragna is now?" System No. XX asked Rachel.

"I don't have memory of that, but I'm still finding him, because I... feel it." Rachel replied.

"'Shut up, I hate you, you stupid jerk!' I see you, Kusumi-no-Okami." Satanel noticed Marie/Izanami.

"How did you get to be human?" Mercurius asked System No. XX.

"Ragna sacrificed his own existence to save his family and his world. After that, a lot of alternate timelines and possibilities in his world went haywire somehow." System No. XX explained. "Eventually exacerbated by the spreading of the Rifts. I grasped the possibilities and allowed myself to transform."

"You're as human as you're machine, just like I am now." Angela replied to System No. XX. "We're not so different at all."

"Thank you for using Pantheon and providing me your powers." Kouha thanked System No. XX. "We are also free."

"Tenma Jumpson, Captain Velvet Meteor, check the top room." Rachel told Jumpson and Velvet Meteor. "By the way, I'm Rachel Alucard."

"Ok, we'll spy on Empress Zero." Jumpson accepted.

Jumpson and Velvet Meteor then climbed up to the top floor without being caught, and went to stealth.

"Wait, he sacrificed his own existence?" Rachel asked System No. XX."

"To save his family and his world." System No. XX replied. "And you still trying to find him?"

"Yes." Rachel confirmed.

"Then there's something surprising for you..." System No. XX then revealed. "Ragna is brought back to existence thanks to the rifts clashing with the possibilities."

"I even met him while I was possessing Kouha." System No. XX revealed.

"Ragna? He's... back?" Rachel is shocked.

"I even met his family, as well as v-No.13-." System No. XX continued. "Right after Prometheus was paralyzed."

"What's your human name?" Hegemony Marie asked. "'Margueritte Breuil' is mine."

"It's Kousako Kansatsubi. I have to pun out my real name gracefully to think about it." System No. XX giggled.

観察美交差子 (かんさつびこうさこ)

"You basically answered my next question." Hegemony Marie responded. "I was going to ask you how did you come with that name."

"Let's reactivate the Akasha Terminal." Kouha told Mercurius. "Tell Nahida to help provide it."

Mercurius concurred and did what Kouha said. The Akasha Terminal is now connected to the entire alliance.

"I have been freed alongside the other Hegemony Gods, as well as Tenma Jumpson, Captain Velvet Meteor and their friends, by Angela, her co. and then some!" Kouha reported. "I also approached Rosalina, System No. XX a.k.a. Kousako=Kansatsubi, Rachel=Alucard and Kusumi-no-Okami, at the second-highest floor!"

"Wait... Rabbit... She's still finding me, even after my sacrifice!?" Ragna is shocked.

Not so long afterwards, the alliance arrived at the cell room, meeting the Hegemonies, System No. XX, Angela's companions over the years, Raiden, Access, Rosalina, Marie/Izanami and Rachel.

"You're... found you!" Rachel cried at Ragna.

"Rabbit, I'm back!" Ragna then crashed Rachel's cell.

"Rosalina!" Mario and friends bright back to Rosalina.

"It's you!" Rosalina met in the cell.

"Emmy! We're back!!!" Teddie ran towards Marie/Izanami.

"Finally, some reunion." Junpei Tenmyouji exclaimed.

"And so, the alliance of saviors, both good and evil as well as in-between, have reunited and bright with more of their kins!" EX paraphrased.

"Did someone forget the ultimate midnight snacks?" The tortured Princess asked.

giggles, transforms back to civilian* Well, so far so good." Kai Iod exclaimed. "Relatively, of course."

transforms back to civilian* "I want to know how you did."

"Revived Al-G, busted Nemesis and corrupted Tri-Edge attacked us in the gate." LeBron reported. "We defeated them. We're fixing Tri-Edge right now."

"We're teaming up with mechas and robots, including Gattais and Megazords." Tak reported through Akasha Terminal. "We're flying toward the suspected destination."

"Good." Reiji and Kogoro replied.

"Jumpson and Captain Velvet Meteor is spying on Empress Zero?" Mii wondered. "I hope they don't get caught before we get up there..."

"I'm carrying the Portalstone right now, and I'm too large to have it boost me here." Meden complained.

"No wonder why you're holding it all along while running up, my darling." Due replied.

Meanwhile...

"We have some complications." Rigna reported. "The alliance has managed to infiltrate the Library!"

"Hmph." Zero the girl isn't amused. "Find them through security."

"Shhh, be quiet." Jumpson whispered.

"Ok. We can't make any noise." Velvet Meteor concurred. "Even those wardens can hear us at any time, should we blow the cover up."

Jumpson and Velvet Meteor sneakily heard the reports.

"However, the preparation is complete." Fusion, as Ikue Higashi, reported. "Cursa is back, and the legion is formed."

"Good." Zero the girl responded. "Find the mechas, and destroy them."

"All hail..." Empress Zero's servants saluted.

"Akasha Terminal, now!"

Jumpson and Velvet Meteor activated the Akasha Terminal.

"Genjitsu-no-Omnia!" Empress Zero's servants saluted, unknowingly revealed her true name.

現実のオムニア

"It's her name!?" Jumpson is shocked.

"Yomi! It's Genjitsu-no-Omnia!" Velvet Meteor contacted with Yomi. "You're right when you said that you know Empress Zero's name!"

Yomi is shocked at the reveal.

"I'm right all along..." Yomi realized. "She's Genjitsu-no-Omnia, the caster turned castaway of the Last Reality..."

"Yomi, what's wrong?" Hirume asked.

"It turns out that my foundation was correct." Yomi revealed. "I previously didn't have the chance to say it, but..."

"Lucy, listen." David connected the Akasha Terminal to Lucy (who's in the moon at the moment).

"Oh." Lucy tuned in.

The Akasha Terminal is given to the alliance as well.

"This is the chance for me to say the name, now that Jumpson and Captain Velvet Meteor found out." Yomi is ready. "Empress Zero's real name is... Genjitsu-no-Omnia."

This revelation came as a shock to the alliance, and even robots who's heading to the destination.

"Unbelievable..." The mecha pilots are shocked. They still piloted their mecha as normal.

"I forgot her name before as to hide the truth, but now I understand." The Cube Queen realized. "She's the one who eventually messed up after the Cube King's departure."

"Before all that, she's one of the best candidate to follow and succeed our rule..." The Cube Queen continued. "Guess the controversy back then drove her away and into events that would drive her insane."

"Ridiculous, no so graceful of her." The Origin commented.

"Unbelievable..." SMG4 is disappointed.

"I previously didn't have the chance, but now I did." Yomi continued.

"Genjitsu-no-Omnia... We'll get you!" System No. XX sworn off.

"We've revealed the name." Jumpson reported. "Good job, Captain!"

"Finally! People in all worlds will know the facts!" Velvet Meteor replied.

A warden is walking around, so both hid quietly.

"Everyone, in case of the security knowing here, run and hide!" Hirume told everyone.

"How about we hide in shadow for some time?" Ushio Kofune suggested. "We also sleep there as well."

Ushio casted her shadow, and Sasuke used his Sharingan. The alliance dives into their shadow projections, then hid into the cells, besides System No. XX and Rosalina. And everyone slept.

At the actual morning...

yawns* "Looks like we almost overslept." Jumpson woke up.

yawns* "What's up?" Velvet Meteor woke up.

"Let's sneak to the cells."

Both then went back to the cells where Rosalina is. They found that the alliance just woke up as well.

"Hello, Ushio... hello, Mr. Gabimaru..." Velvet Meteor said hello.

"You forgot I told you... Just Gabimaru." Gabimaru corrected Velvet Meteor.

System No. XX is still sleeping, while Rosalina is gone now.

"Hey, Google, call the mecha pilots." David took the call. "Hello?"

"Huh?" Shinji Ikari in Unit-01 called.

"What's up with the mission so far?" David asked Shinji.

"We've all arrived to the destination." Shinji reported. "Cursa should be here any time now."

"Why are you waiting?" David asked again.

"It's not the time yet, but something will come out for us to fight." Shinji continued.

A few hours later, David finally done report, and suggested everyone to hide in shadow on the cells again. Just in time, as Stormtroopers infected by Sigma-Virus arrived to bring the jailed up.

"Come, it's time to go!" The Stormtroopers took the prisoners.

"Huh?" System No. XX woke up. "Why?"

Stormtroopers did not reply. They took System No. XX as well.

How did System No. XX get caught? After leaving Kouha, she's captured by Fusion as Cure Union. Rigna seals her powers away to make her completely helpess as Empress Zero's servants imprisons her and other surviving victims until the time comes. For the next month passed between the alliance's day 15 and till not long after the reunion in day 16, she, Marie/Izanami and Rachel tries desperately to find some way to escape to no avail. No help was coming to save them either. Once the time comes for Genjitsu-no-Omnia's next move, System No. XX, Rachel, Marie/Izanami and other prisoners are to beforced to watchas Rosalina is to be sacrificed for the move, meant to utterly shatter their drive and hope forever, as the servants executes the prisoners.
