Ch 1 Prologue 1

Journal Entry One

Today was a cause for celebration, my eldest son; Louis's birthday is today. He will be twelve, a young man in my mother-in-law's standard; but to me, he's still my baby boy.

I'm not that surprised that he took after my looks, blonde hair, and facial structure. But his eyes were a hint of mine mixed with his mother's bluebell eyes. An angel sent from the Heavens if I do say so myself.

Today was perfect.

Journal Entry Two

Tonight was going to be fun; my second son, Hugo wanted me and Louis to stargaze tonight. The news has foretold a meteor shower will happen this evening. My wife wanted to go but my daughter Emma, was being fussy with a fever; so they have to stay home.

Hugo was really excited to see the meteor shower with us. He was a bright boy who had taken interest in astronomy, he could even name the planets and constellations; I'm so proud.

My firstborn has taken an interest in art just like his mother. My children are very special indeed.

We sat with my best friend, Nino, and his daughter watching the night sky. My second son points to every star in the sky, naming them by heart however one constellation made him dumbfounded. The arrangement of the stars was odd.

Six stars in a circular formation; even I don't know what the constellation was. But we decided to move past it when the meteor shower started, it was a spectacle. The face my sons have on their faces was a joyous moment for me.

Today was perfect.

Journal Entry Three

It seems that night of the meteor shower wasn't the only spectacle that came. I sat next to my wife, Marinette watching the news in our apartment while the kids played in the background.

Turns out scientists had discovered a strange asteroid, landed on the outskirts of the city. They say it was thousands of years old.

We saw the strange celestial object on the TV during an interview. The asteroid was indeed strange, unlike normal asteroids, this one is white and shaped as a cube! A cubed asteroid, something that has never been discovered in ages.

Today was interesting.

Journal Entry Four

We never encountered these enemies before, there were all black with circuits all over their humanoid body. Both my wife and I have to call in for help, these enemies were tough to beat but were vanquished.

During our monthly meeting with the League, we have concluded that these enemies were Sentimonsters made from the new Shadow Moth.

Today was really strange however good.

Journal Entry Five

THEY WERE NOT SENTIMONSTERS!

They are worst than Sentimonsters, they were monsters, soulless automatons with no regard for their actions. They have injured the Fox seriously, but we manage to defeat them.

Today was bad.

Journal Entry Six

The Turtle is injured.

Journal Entry Seven

The cube meteorite that the scientist found in the outskirts of town has been acting strange. It glowed ominously, my instincts were kicked into high gear like it was saying 'Get out and save your family.'

The next day the cube, (Now what we call it in the League) was stolen. A huge hole was in the roof of the research facility that it was in.

No one knows what's happening, but one thing is for sure…this was a bad omen.

Journal Entry Nine

The Monkey was first to fall.

Journal Entry Twelve

The Horse, the Ox, and the Mouse fell to the strange enemies.

Journal Entry Fourteen

Everyone was restless, six Miraculous were lost. Our Leader was stressed, and I'm no help.

More and more of these enemies appeared when the cube suddenly vanish. They were more monstrous than and stranger than the previous ones.

Every day things are going downhill, what is going on…

Journal Entry Sixteen

There was a hostage situation at Town Hall. The Mayor was being held captive along with his governmental officials by the enemies.

We argue, our leader doesn't want to take any more losses. I agree with her, but the Bee, the Tiger, the Pig, the Rooster, the Dragon, wanted to save them.

Our leader, me, the Snake, the Rabbit, the Dog, the Goat disagreed with them. It was a risky move for the League; however, they went ahead.

Journal Entry Twenty

It's been weeks since we last saw the other members. The people of Paris are getting anxious, afraid, no…terrified.

We remaining members continue our crusade to protect the people and search for the Mayor and his cabinet along with our missing members.

I just hope our children don't see our disarray situation.

Journal Entry Twenty-Three

We lost contact with the other countries; a strange pillar of light appeared where the Eiffel Tower stood…then a huge floating castle landed on the historical landmark.

Everyone was scared of this strange structure was, then…then he appeared. A white-haired man with a golden crown and armor. I remember his totalitarian voice clear as day…

"I am Ruler of the Eternal Empire; this world is damage. Beyond repair." Ruler announced to the citizens of Paris. "I've been observing how you live your lives, and I found how chaotic this Paris is."

Ruler looks down at the people, in awe of his majesty. "Thus, as the generous Emperor of said Empire. I shall lead you all to prosperity and ensure your safety in my arms." He proclaims, raising his hands in the air.

The Ruler of the Eternal Empire has brought out the Mayor and the rest of our teammates for all to see.

We were horrified at their condition, they were thin, malnourished, and tortured.

I gritted my teeth at how he treated my friends like that. My eyes caught someone standing behind them, a woman with white hair and golden eyes in a dark green dress. She had a fan covering her face, and her hair was curled into a ponytail to the side held up by a crown-like bow.

I was about to rush over and save our friends from their clutches however our leader held me back.

I yelled but she retorted back for going in without a plan. And she's right however that proved that we were too late.

Ruler looks down at the Mayor, "For the crimes of your fellow Persian, execution shall be administered." He announced.

We shouted not to kill the Mayor; however, he ignores our pleas and took out his sword. With a single swoop, the Mayor's head was severed.

The people cried in horror, anger, but we stood there in disbelief. Frozen at how a man could do this to his fellow man.

What Ruler say next had us to act quickly, "I merely paving the way for Human prosperity, an Empire where no Human shall ever feel pain. As such I shall prune away those who dares to shatter that prospect." He announced.

"Tonight, these conspirators of the Miracle League shall share the same fate as your previous Mayor." Ruler of the Eternal Empire stands before the people of Paris, his arms wide open. "Long Live Humanity, Long Live the Eternal Empire!" a wave of energy blasted throughout Paris, however, nothing happened yet.

From that speech, we decided to not follow the Emperor's plan. That night we shall defeat this Ruler and prevent this Eternal Empire from ever being established…

Oh, how wrong are we…

That day was the worst day of my life...

A ladybug themes superhero leaps across the buildings of Paris, her eyes draw downwards seeing the police stationed in front of the castle. "We need to hurry before things get really out of hand."

Chat followed his wife's lead along with Viperion, Bunnix, Carprikid, and Traquemoiselle.

"Ladybug, I can smell their scent. They're at the center courtyard of the castle!" Traquemoiselle used her power of tracking to locate where the missing members are.

Ladybug nodded at her information. "Great job, Traquemoiselle. If we do this right then we can save our team before Ruler of the Eternal Empire ever finds out." She said hoping that it would turn out like what they've planned.

Bunnix landed on the roof, following Viperion. "So, what's the backup plan in case we fail?" She asked the blue-haired hero.

Ladybug stopped, looking at her friend. "Bunnix, in case we fail you need to go back in time for help." She told the Hero of the Last Chance.

Chat smirks, "Viperion can give us a second chance when a total CATastrophe happened." He jokes in light of their situation.

"Really? Jokes at this moment, Chat?" Carprikid questions the Cat's motives.

They all groan at the pun that the Hero of Destruction made during this moment. "You really like to make jokes out of everything, eh Chat?" Viperion smiles, seeing the cat shrugs.

"Eh, despite the situation I want to make things lighter than it already is." Chat said, wanting to have a last-minute joke before facing their biggest threat yet.

Ladybug sighs happily, loving how her husband could make things better with a simple joke. "Alright, let's get going before we're too late." They all agree and leap over the buildings and onto the landmass that was on top of the Eiffel Tower.

They all sneak into the castle, pass some Attack Programs guarding the entrance; however not the wall.

Chat was on the lookout, finding the entire place void of guards. "(If this is a castle, shouldn't there be guards around?)" He asked his teammates.

"(You're right, somethings way off.)" Carprikid commented, finding the halls quiet…ominous.

Traquemoiselle was following the trail of the scent of their comrades before entering the courtyard. "Ladybug, I found them. But…" She only spots Ryuko chained up in the center. No one else, just her…unguarded.

"Definitely a trap." Chat stated out the obvious.

Ladybug looks at Viperion, knowing what to do. He placed his hand on the bracelet on his wrist and tug the snake on it. "Second Chance."

"Now we can return to this point in time." Ladybug smiles at the Snake Hero for being here. "Alright, let's get going."

"Yeah," they all jump down from the wall, rushing over to their fellow Miraculous Holder in need.

Viperion was first to get to the Dragon Coker Holder, breaking the chains that bind her. "Ryuko, are you alright?" He asked his wife if she's unharmed.

Chat, Carprikid, and Bunnix were on guard, ready to defend their injured friend. "Is Ryuko alright, Ladybug?" Carprikid asked the leader of the League.

The blue-haired superhero leans down to her fellow Hero. "Ryuko, are you alright?" She places her fingers on her wrist, checking her vitals. "She's alive," Ladybug sighs in relief.

Viperion watches as his wife opened her eyes. "Hey, you gave us a scare." He chuckles, helping her sit up. "Ryuko, where are the others? Are they safe?" he asked.

Ryuko shook her head, gaining her consciousness back. "Yeah, I'm fin-VIPERION!? LADYBUG!? No, no, no, no, no, you can't be here." She panics,

"Ryuko, calm down. Everything is going to be fin-"

"No, you don't understand. This is a trap, the others…they were-" Ryuko stops, hearing footsteps from the entrance to the castle.

Everyone looks at who the footsteps belong to. "Well, it seems Caster of Versailles's prediction has come true. Her transgressions at the Wandering Sea have now been overlooked." A blonde man in a white suit and a wine glass in his hand commented. "I must say, in a world that Magecraft died out you all have accomplished something that Mages could do." he smiles.

'Mages? What are Mages, is he talking about the guardians?' Ladybug ponders on his words. She pushes it to the side for now and focuses on the potential enemy. "I have no idea what you're talking about…"

The man simply bows to the Micale League, his smile is hiding something sinister. "Foreigner of London. I'm the attendant to Ruler and Avenger of the Eternal Empire, please to meet you Lady Ladybug." Foreigner greeted them.

"Foreigner of London? What kind of name is that?" Chat asked, finding his title really weird.

"Ah yes, that's just my cover for my True Name." Foreigner explains. "But sadly you don't have the time to learn it I'm afraid." He sighs, snapping his finger. "Oh, Saber of Gascony?"

Chat looks over to the side, seeing a red-haired man with violet eyes in a black colored shirt and a red tie, outside was a white military jacket with golden buttons.

He wore reddish-brown pants and black high knee boots. A black cape with golden fabric on the hems inside was a crimson color like an apple. His gloves were the same color as his pants, holding a black scabbard rapier with a golden handguard.

If his appearance screams out respect and honor, however, his face says otherwise. Chat can tell this man was displeased by this like he was being forced. "Yes, Foreigner?" His voice, dead in tone with no hint of emotions. (Insert Fate/Grand Order - OST - アージェンシー)

"Please tend to our guest." With that, Saber leaps over to Bunnix who repel his strike by her umbrella.

Bunnix was shocked to see this man's strength, he was able to push her back to the flowers. "W-What strength." She huffs.

Carprikid and Traquemoiselle appeared behind the Saber when a flash of light stops them. Both Miraculous Holders fell on the ground, unconscious as Saber landed gracefully on the ground.

The red-haired Saber looks down at the fallen heroes, saddened that they can't stop him. "Is this what the Miraculous Holders are capable of?" he asked, hoping this isn't it.

Ladybug flung her yo-yo at the Servant, only to be blocked by his sword.

'This strength, he can overpower us without breaking a sweat.' Ladybug looks over to Bunnix, leaping to get in a strike.

"Damnit!" Bunnix cried, being pushed back by the Saber of Gascony. Without thinking, she was kicked in the face, flying across the yard and to the gate.

Ladybug rushed over to attack the Saber; Chat followed her lead. "Chat, hit, and run!" She cried.

"Gotcha!" Chat caught on what his lady was planning.

'Hit and run, I see.' Saber looks at the window, seeing the figure of his master observing him. 'I must win, no matter what.' He thought.

Chat strikes Saber with his baton, being blocked by his rapier.

Ladybug did the same thing, however with her yo-yo.

None were getting anywhere; the duo was already tiring themselves out. They've been at it for a while and ain't getting anywhere. "This has gone far enough." The Servant sighs, spinning around gracefully to push the two away.

Ladybug and Chat Noir were thrown back to Viperion and Ryuko. "Y-You can't d-defeat him. H-He's on a d-different scale than us." Ryuko informed the two.

"Was he the one who defeated you all?" Ladybug asked her friend if he's the one who took out every Miraculous Holder who went to try to save the Mayor.

Ryuko shook her head. "N-No, he's not the one. He's new." She told the leader.

Chat Noir looks at his ex, wondering what she means. "What do you mean new?"

"Then who is the one who defeated you all?" Viperion asked, seeing the situation becoming dire with each second they spend staying here.

"S-Some one whose much worse, he's like a storm of rage. Insane, ruthless, and coldhearted." Ryuko shook at the mere thought of the man who they've faced. "H-He…He…"

Viperion noticed his wife trembling in his arms, not wanting to see her like this he immediately took action. "Ladybug, I'm going to do it. We're clearly outpowered."

Ladybug nodded, looking at the unconscious Carprikid and Traquemoiselle. Bunnix was getting up, about to sneak over to strike at Saber of Gascony.

Chat nodded, agreeing with Viperion. "We have to," holding on to his wife's hand.

"Alright, go for it." Ladybug approved of Viperion's plan.

Viperion smiles, about to use Second Chance when something else happened. "GAK!" He was being strangled from behind.

A blur of white mist was standing behind Viperion. "What the-!" Ladybug lunges forward, grabbing the figure by the waist as he drops the Hero of Second Chance.

Viperion fell to the ground, unconscious from the choke. "Viperion!" Ryuko and Chat Noir rushed over to the Snake Bracelet holder, sighing that he's still breathing.

Without hesitation, Chat Noir and Ladybug rushed at the new enemy. The Heroes were blasted away at his impressive strength. They landed on their feet, facing the white blur while coming up with a new plan. "We can't be it, what is that thing?" Chat questions the power this thing has.

Ladybug gritted her teeth at the enemy before her, however, something about this enemy is familiar. "Who are-" Her words were interrupted when a white rope wraps around her waist and drags her over to him.

"Ladybug!"

"Saber, that's enough. You've done your part well." Foreigner order the Servant to withdraw from the battle.

Saber of Gascony nodded, turning swiftly to strike at Bunnix. "GAH!" leaving her defenseless on the ground.

The Anomaly Servant looks back at the battle, then at the Hero of Time traveling. "(You should go before Alter Ego of White gets you as he did with the others.)" He informed the Hero of Paris.

Bunnix was confused about what he means by that. "W-What?"

Before Bunnix could ask more questions from Saber of Gascony, he leaps into the castle. "W-What does he means by-"She was interrupted by a loud explosion, her head turns and saw Ladybug gasping for air.

Chat was thrown back to Ryuko and unconscious Viperion by this thing. He looks up back at Ladybug, hearing her crying out. "Lucky Charm!" Ladybug cried.

"A golden card?" Ladybug questions, seeing the strange object. "What am I supposed to do with this?" She quickly observes her surroundings, flashes of red and black spots appeared on Bunnix, Viperion, and Ryuko. "Wha-"

Traquemoiselle and Carprikid struggle to get on their feet but manages to stand. "Alter Ego, take them out." Foreigner orders the Servant.

In a flash, Alter Ego appeared behind Traquemoiselle almost like Voyage by Pegasus. "Wha-" He grabs the Dog Hero by the neck, strangling her. "H-H-He-"

"Traquemoiselle! Hold on!" Carprikid rushed over to help his fellow Parisian Hero when Alter Ego's other hand morphs into an orb with a needle.

Ladybug instantly knew that shape from Vesperia's Venom. "How can he obtain that power!? Unless…" She realized what this means, the reason why the others weren't with Ryuko was that…

Carpikid was about to strike at Alter Ego when stung him with great speed. "GAK!" he gasps, unable to move in his place. "W-What is going on."

Alter Ego moves his attention back to the Dog Miraculous Holder, his grip on her neck tightens. "LET HER GO!" Chat cried out, rushing to save his friend however he was too late.

Bones cracking echoes in the ears of the Parisian Heroes. "NO!"

"AHH!" Ryuko gasps at the sudden death of her friend.

"Traquemoiselle!" Bunnix cried out in horror.

"Sabrina!" Ladybug cried, her hands drop it slowly realizing they were fighting a losing battle.

"NO!" Chat ran towards the Alter Ego, he stops in his tracks noticing that something is happening to Traquemoiselle's body.

The mist from the Alter Ego's body engulfed the dead hero, Traquemoiselle's body was absorbed into the very being of the Servant. His eyes turn over to the Goat Hero, slowly walking over to him.

Chat gritted his teeth, not wanting to see his other friend die in the hands of the enemy he continues his path. He leaps in the air with his baton in his clawed hands. "I'LL KILL YOU!"

"CHAT NO!" Ladybug cried out, seeing the Servant swatted him away like a fly in the air.

"AAAAGGGGGHHHHHH!" Chat was thrown over the stone wall, knocking him unconscious.

The Alter Ego was behind Carprikid, taking his head and twisted it in an unruly manner. Once the Hero was dead, the Servant proceeds with the action he once did to Traquemoiselle.

Ladybug must act quickly, she looks over to Bunnix. "Bunnix, retreat! Take Ryuko and Viperion with you." Before Alter Ego of White Before Alter Ego of White gets to the Time Traveler, Ladybug threw her yo-yo at him.

"HEY! IF YOU WANT TO FIGHT, THEN FIGHT ME!" Ladybug calls him out to fight her.

Alter Ego of White rushed at her, punching her gut. He grabs her and throws the Hero to the other Superheroes.

Landing next to Ryuko, she handed her the golden ticket to the Dragon. "Run, I'm not sure what this golden ticket is for but it's the lucky charm." She informed her friend.

Ryuko took the ticket and gently taking Viperion's arm over her shoulders. "What about you?" She asked knowing this was a risky plan she came up with.

"I'll distract him while you all make your escape. Chat will be with me," Ladybug saw Chat Noir getting up from the ground, determined to defeat this monster. "And make sure that Miraculous is guarded safely, it's our only hope."

The Dragon Hero nodded, understanding what needs to be done. "Alright, good luck." Ryuko drags Viperion, despite being injured herself.

Bunnix ran to them, helping to take Viperion off the blue-haired woman's shoulders.

Foreigner got a message from his master, telling him to pick up Avenger of the Gallows. "Fine." He snaps his fingers, turning around from the battle. "Deal with those two. I'll leave you be." He orders the Servant.

As usual, Alter Ego was silent not even agreeing with the Foreigner. But he did what he was told, like a machine.

The white blur and Ladybug clash with each other in hand-to-hand combat. While they were doing this The three Superheroes escape the castle and were on the streets of Paris.

Chat Noir got up, feeling like he was hit by a train or a plane. His cat-like eyes looked up, what comes next was heartbreaking to see. (End Song)

Ladybug didn't see it coming, he was too fast. Whoever this Alter Ego was, he knew all of her battle styles and where to attack.

In a split second, his fist plunges its way into her chest and through her back.

"NNNNNNNNNNOOOOOOOOOO!" Chat cried, tears pouring out from his eyes at the sight of his lady being killed right before his eyes. "MARINETTE!"

Ladybug grins, taking off her earrings in her left hand. "I knew you want my Miraculous," her costume returned her to civilian form, Tikki came out of the earrings and quickly taking it, "GO TIKKI! DESTROY THE EARRINGS!" Getting to a safe distance, Tikki looks back.

"Marinette…" Tikki tears up, knowing if they got the earrings then all will be lost. So as a percussion, the Kwami threw the Ladybug Earrings on the ground. The impact shattered the Miraculous of Creation along with the Kwami of Creation.

Chat fell to his knees; his wife just destroyed the last hope of saving Paris. Marinette smirks at her enemy, "Now you don't h-ha-hav-"from her wounds, her body began to turn white. However, she accepted her fate; with the lucky charm she gave to Ryuko, all will be well.

Marinette knew this power too well; she looks at her husband whispering something to him before being blown away from the wind.

The Cat witness the love of his wife die before his eyes. Anger, grief, vengeance were filling up in his mind, wanting to kill this man who killed his wife; he acted without thinking. "I'LL KILL YOU LIKE YOU KILLED MY WIFE, CATACLYSM!" A black orb appeared in his hand, rushing at the Alter Ego.

The Servant remains steadfast, he grabs Chat's arm with the Cataclysm and places it on his chest.

Chat gasps, feeling his own power of Destruction used on him. He had a lot to live for, his children, his friends, he was being taken away from their lives. Everything was turning black as his body crumbles away before being swept.

Everything was black, no sound, no setting, nothing just an endless void. "W-Where am I?"

"…"

Chat saw a faint blue light in the void, then a voice spoke to him. The dead Hero looks around his surroundings, in search of the voice. "W-Who are you?" He asked.

"…"

The Cat-themed Superhero's eyes widen what the light is offering to him. "W-What do you mean a chance? What is this about!?" He demanded of the voice.

"…"

Chat no, Adrien's eyes darken hearing what the voice is offering. "Alright, I'll do it." He agreed to the offer of the voice.

"…"

"Transformation? What do you-" Adrien was interrupted by the transformation. He still retains the black cat-suit and mask, however, his cat ears were replaced by a hood with Cat ears sticking out. His baton was taken away, however his claws were now green that fades into the midsections of his arms. "What the-"

"…"

Adrien looks surprised at the name he was given by the voice. "A-Avenger? Wait, why can't I- A Noble Phantasm?" He questions the term it used. "So I can't reveal who I am, but I can tell when I'm ready? Alright, whatever you say."

"…"

"WAIT, WHERE?" Adrien's eyes widen at where the voice is sending him. Before he could respond a bright light lit up the entire void, transporting him to an odd setting.

Winged men were everywhere in their hands was a Flaming Sword which he knew right away on what they are. 'Oh, you got to kidding me.'

Like second nature, Adrien spoke. "Servant, Avenger! I've been sent by the Counter Force to request the help of the final master!"
