The O.M.A.C. avatar chose the twilight twins as the unlikely recipients of the O.M.A.C. virus.
But both's magics stunned the virus, temporarily electrocuting the avatar.
"M'lady!" The butler noticed the change.
Both twins got glowing red extra slit pupils in their respective eyes, and the Brother Eye is glowing on top of their chest with their commonly associated magic colors. Their hairs partially spiked up slightly, and their eyes then stop glowing for now, signifying setup complete. While the avatar, overwhelmed by magic, got equivalent to getting tired.
"Two ladies receives a computer virus by connecting it with magic." Ishmael saw the shift. "It's as interesting as it gets for today. But..."
"What the hell is O.M.A.C. anyways?" The Sinners discussed.
"Observational Metahuman Activity Construct..." A shadow behind O.M.A.C. spoke up. "Using two fantasy girls to do the dirty work, ain't you..."
"I cannot hear Brother Eye anymore." A knight noticed. "Is that satellite shutting us off in favor of the Princess? Or the lady?"
Charlotte glanced down at the shadow beneath the O.M.A.C.
"Shit, that damn villainess spotted me, maybe I shall..."
But the princess took the Kinetic Ore and went for Dash Attack to the shadow, knocking a shadow off O.M.A.C. and shocking everyone else but the avatar.
"Another darkness, just like me." A bat-cowl-like humanoid black monster emerged from the said shadow.
"Bruce Wayne! Why are you here!?" Charlotte suddenly exposed the monster.
"O.M.A.C. has already been exposed to the knowledge of the multiverse eye came from, and noticed the said monster who caused two of the Crises." O.M.A.C. pulled the information. "Infos from both the multiverse and the internet on those two... smartphones lying around."
"I was a Batman who laughs. To win you need to adapt, and to adapt, you need to be able to laugh away all the restraints: everything holding you back. A Batman wholaughs... is the Bat who always wins." The monster smiles. "But Batman has always been a reactionary idea.He was born in response to those gunshots in the alley. And just as he is a reaction, so too are the twisted Batmen of the dark, those that I used to lead. Even the most dominant is still a reaction to some fear that has shaped him, built him into a newer, crueler incarnation, perfectly designed to overcome it. But as I am, I amnota Batman of any kind. Not just a Batman Who Laughs, not really a Batmanhattan, and not even a culmination of all dark Batmen."
"Nowadays, I am more. And to be more, I must not be a reaction. I must be the thing that creates the reaction itself. I will be the bullet that cause tragedy. The multiverse... no, the omniverse will be thedark alley. And its worlds... no, it's realities will fall like pearls before me... actually, us." The monster continued. "I am no dawn. Not even those blue, or even golden lights. No, I am the-"
"Darkest Knight." Charlotte dropped the monster's name. "The Batmanhattan Who Laughs."
"You are not a Batman, yet you are parallel to Batmen." The Darkest Knight responded. "You lost your mother in a tragedy, just like a Batman lost his parents. You are vengeance. You are the night. You are of... shadow."
"Brother Eye, get rid of Bruce Wayne of Earth-(-22)!" Charlotte attacked the Darkest Knight.
The Darkest Knight let out an evil, psychotic laughter as the princess proceeds to beat him down the princess way and then some. "I thought you would get along with me, as you share the dark features with Batman himself!"
"Butler Eye, please get me something to work alongside my light!" Angelique pleaded while Charlotte went studio Trigger combat against the Darkest Knight.
Suddenly, the now reality-warping Brother Eye intelligence got automatically equipped Angelique with the a space patrol suit that one would probably recognize... and then...
"Awake! Judgement Gun Morphing!" And Angelique gets transformed into a giant handgun.
"What the... Oh no no no no no! What is this!?" Angelique panics upon her gun form. "A gun form of a thing called... Luluco!?"
"Fight for Justice!" Cue gunfire.
"Yeeart!" Charlotte pushes the Darkest Knight into the way of the light bullet.
The bullet blasted the dark monster out of the castle, with the people under nearby getting to see the thing flying out.
"Your magics aren't from my multiverse at all, and magical by nature, so that means..." The O.M.A.C. just standing nonchalantly.
Nobody but the twins heard the avatar.
"That bot's saying that our magics are not from its multiverse then..." Angelique paraphrased. *turns back to human form*
"We turned Brother Eye into a reality warper!" Yay, Princess.
"Please dispose of the monster, they are trying to invade us." Angelique told the avatar.
The O.M.A.C. simply got out and searched for the Darkest Knight.
"O.M.A.C. apparently let us do anything, as provided by sending commands to Brother Eye." Angelique then brought the Sinners to the Mephistopheles.
With the new super-strength from the O.M.A.C., the twins were able to pull the vehicle out of the way and back to ready.
"Thanks, thanks, thanks." Charon nodded.
"You Sinners stay in that machine." Charlotte put the Sinners inside. "I'll take other."
Cue the friends and the love interests (just got known each other) taking the DeLorean. "Can we escape now?"
"There is no inferno in this strange place." Charon shrugs.
("What the fuck?") Dante (the Sinner, the manager) facepalmed.
"Thankfully, the Darkest Knight is out. I scanned and he's nowhere to be found." Angelique reassured. "Everyone, enter the train-bus!"
Then various people from the kingdom and some, ranging from country folks to aristocrats, all nearby the castle, are all notified by the princess to enter the Mephistopheles. Charlotte didn't find the monster anywhere, suggesting that it is safe for everyone to refuge and get into the vehicle.
But a few dozens of minutes later, an earthquake suddenly hit the castle.
"Get in!" The Sinners has directed about a hundred survivors to Mephistopheles at this point.
"Dunno how many people can it fit..." Charon glances at loads of survivors cramming through the door.
"What?" Charlotte noticed the ground shaking.
"You have made a mistake. You let this nanite figure take me. Oh, I planned your kingdom's forced downfall..." The voice of the Darkest Knight. "... because you, whose dream came true through reincarnation, has become one of our prime targets! I have planned for it though, so lo and behold!"
"The Darkest Knight is coming! Hurry!" Charlotte warned everyone.
"Dark Nights protocol, activated." A literal Batman-like figure with three eyes and blue tron (body)lines emerged. "I am not the Darkest Knight anymore. I am not O.M.A.C. I am not the final Bruce Wayne. I am not just a reaction anymore."
"Take care of this old king, please!" Don Quixote cheerfully gave the king to Vergilius.
As the rescue onboard reached 250 survivors, the Mephistopheles is slowly starting to get slightly cramped. Leonardo helped the Sinners by encouraging the survivors near Mephistopheles to enter that vehicle. The rest of the party, including friends and Angelique, enters the DeLorean. And the castle started collapsing.
"Now, I am the bullet. I now cause reactions. I am Batman Who Laughs, transcended." The figure open the eyes. "I am Dark Knight Army Corps... D.K.A.C.!" *psychotic laughter*
Various points of the ground exploded, killing some rescue and starts devastating the horizon in the game world. The castle also collapses.
"I can hear a laughter." Sinclair heard it. "Everyone, get inside!"
Over 300 people (whether or not including those from Limbus Company) has entered the Mephistopheles, and some more survivors steadily entered through its relatively narrow entrance.
D.K.A.C. gains a dark cape modeled after the Batmen's, and casted lightning everywhere. Those barely missed the vehicles and struck some running survivors, killing them.
"We have to get out of this world!" The love interests shouted. "Princess, get back!"
Charlotte returns to the DeLorean and enters it, knowing that the D.K.A.C. is going to wreak havoc to this world and her doing anything else would get her killed.
"Does O.M.A.C. tech work with Cyttorak gem?" Marcus asked.
"C'mon, it should..." Charlotte pushes the start button.
DeLorean briefly bursted with red lightning which then struck Mephistopheles.
("It seems our vehicle has been electrified now. Can we travel to other worlds now?") Dante tried to ask.
Yi Sang phrased Dante's question, and...
"Very well... Can you guests go first?"
The large Mephistopheles then slowly turned back with large tows and cars that's currently hosting a few hundred survivors. And then, the train goes away from the castle, thanks to Charon driving.
"Vroom-vroom," Charon responded.
The Mephistopheles now crackling with red electricity, and sped up. Charlotte reverse-drifted and followed the train-bus. All the doors were closed, leaving hundreds of people in D.K.A.C.'s vicinity.
"No..." One of the people left behind cried.
"You're not going to escape!" D.K.A.C. tried to shoot the speeding vehicles.
"88mph is enough." Charlotte and Charon then throttled ahead.
D.K.A.C. proceeded to destroy this game world as well, and so the ground bursted, killing outsiders and trying to catch the vehicles. But the vehicles then phased and disappeared into lightning just right the moment the ground reached.
"Damn! So close!" D.K.A.C. realized that he's barely too late. "Well, at least this world is doomed anyways." *chuckles*
Cue the D.K.A.C. enlarges himself and crushes the Earth of this otome world with his bare hand.
"Yeah... I killed... billions this very minute. This nanite body is ideal, and complement that one final Bruce... Definitely the upgrade I sorely needed." The D.K.A.C. appreciated the O.M.A.C. "That Superboy who duped me... That Perpetua tried to use me... and the accursed Justice League, including that Batman... forced me too close to the sun..."
"I am vengeance. I am no dawn. I shall not only get back to them, but serve the glorious Beach and make my multiverse a dark alley of mine!" D.K.A.C. continued.
"Mission report? How did this mission go?" A woman's voice.
"Oh, miss Nigen, it's a mixed bag." D.K.A.C. reported. "On one head, that reincarnated villainess escaped with her people and then some. On the other, I destroyed her Earth and received a special upgrade."
D.K.A.C. then teleported.
In Mephistopheles, the Sinners took care of the king, while Charon just drives.
"Thank you... for your kindness..." The king thanked.
"It was the princess's order." Vergilius replied. "But we feel like a shadow has been lurking all along..."
"You're right." Angelique contacted to the Sinners. "Now you can hear us remotely, we already tagged you all. He most likely destroyed the world, and we're getting away into others-"
"That monster destroyed my..." The king is distraught.
Charlotte sighed, and then explained who Batman Who Laughs (i.e. Bruce Wayne of Earth-(-22)) is, and his backstory and road.
"Wait... I have heard him before..." Hong Lu recognized this.
-*flashback*
While the Mephistopheles is traversing across the City...
"La la la la la, la la la la la..." Don Quixote is making fun while onboard.
Hong Lu just starting beyond the window directly besides him in the seat. However, a bat-cowl-like figure suddenly manifested beyond the window.
"Huh?" Hong Lu noticed. "What's this?"
"Have a nice rift!" *laughs*
Hong Lu is confused, but the figure disappeared afterwards. A few minutes later...
"What the...!?" Vergilius noticed something wrong.
The Mephistopheles is crackling with blue electricity. Turns out, it is about to be rifted.
"What is this?" Charon saw the upcoming rift.
And the Mephistopheles got rifted, just like the figure said few minutes ago.
"Wait... I see!" Hong Lu realized.
Mephistopheles is rifted straight towards the Shadow Kingdom, and crashed into the castle. Charon tried to brake, but accidentally pressed both the accelerator and the brake. Thankfully, the vehicle were barely scratched.
-*flashback ends*
"Now I know... that figure is that monster..." Hong Lu finally figured it out. "That 'Batman'... he has been spying on Limbus Company all along!"
"Oh my god..." Vergilius is disappointed. "We didn't see any of it coming until it crashed..."
"He actually hopped between shadows, and saw that avatar of O.M.A.C. we lost, as an opportunity to power him up." Charlotte responded. "Dear royalty, this Batman already has all the powers he needed, and then the Batmanhattan allowed him to use multiversal awareness. Now this!?"
"And also, we now know that he's now working with the Beach that murdered princess's original family." Angelique have news. "Not the first time he served anyone directly."
A while later...
"And so, the edgerunner, with the unity of an omniverse, defeated the wretched rift goddess for good." A mercenary from Night City reading the final part of a novel published by one from another reality. "Zerobreaker no more, the edgerunner finally passed to afterlife and bid farewell to his omniversal crew, including his girlfriend on the Moon. He, an already legendary runner, has become a special-"
Then the Mephistopheles and the DeLorean arrived, shocking the mercenary.
"Wait a second... aren't these like from 2020s' and then some?" The bystanders are confused.
Charlotte leaves the DeLorean, and looked around with her backpack and devices carried.
"This must be the Night City from 2077." Said the princess.
"Who are you?" The people had no idea.
Angelique and the Sinners left the vehicles, and the bystanders were shocked.
"You want some? Now watch." Charlotte snaps her finger.
Suddenly, the floating huge hologram behind her got manipulated, showing Akuyaku Reijou, her family's murder, her death and reincarnation, and about everything about the game, and how this arrival in Night City came to be...
