(Y/n) was in her room as she and Bitz were watching a video from Alya's Ladyblog. The video showed Ladybug flying by as she was hanging on to a helicopter. She dropped something and Alya ran to it. It was a tenth grade history textbook.

"Freak out! What you got here is no ordinary book, it's a tenth grade history book. And I should know, 'cause I've got this very same book. Could our very own Ladybug be a high school student, in real life? Whoa!" Alya questioned in her blog.

(Y/n) paused the video. "Ladybug, a high school student? I wonder if she's someone we know, Bitz."

"She could be," Bitz shrugged his shoulders. "but you must remember that you must keep your identity a secret."

"Bitz, I could keep a secret. I'm just wondering. It would be pretty cool if she's someone I know."

"Probably."

"What would happen to us if I knew who she was?"

Bitz paused as he thought for a moment. "Well, things could get difficult for you guys. In my opinion, if that ever happens I know that you two will keep each other's secret.

Bitz flew up and nuzzled (Y/n)'s cheek. She giggles and hugs him close. (Y/n) received a text from Alya asking if she wanted to come to the Louvre and find something historical about Ladybug on the exhibition on pharaoh Tutankhamun. (Y/n) agreed since she had nothing to do today. She grabbed her bag and went out the door.

In the Louvre museum, Alya, (Y/n), and Marinette were walking towards the Egyptian exhibit to find anything about Ladybug

"Can you believe it? All I gotta do is find to do who this history book belongs to and BAM, I figure out Ladybug's true identity! I'm so on this one!" Alya said in excitement.

"Wouldn't that be a bit of a challenge, because lots of high schools might have that textbook?" (Y/n) asked.

"Yep. 'Cause our school is the only school that uses that book! HA! So, all I gotta do is find out which girl in tenth grade lost her history book last week. There are forty-three girls, not counting myself--" Alya began to count.

"Forty-one! Not count you, (Y/n)... or me." Marinette said. Alya elbows Marinette. "Hmm, yesterday somebody didn't have their textbook in class."

(Y/n) saw that Marinette became worried. "I left it at home. You know how I always forget my stuff." Alya chuckles. "Just messing with you, Marinette. Of course I'll only drop you from my investigation when you bring your history book back to class."

"She's got you there, Marinette." (Y/n) smirked.

They finally made to the Tutankhamun exhibit and tried to see if they could find anything with Ladybug. They were suddenly interrupted when someone ran between them. It was Jalil, Alix's brother, he pushed past them and dropped his papers. he falls and caught something on the floor. A pendent.

"It's not broken!" Jalil sighed in relief.

"Uh, I'm okay too, thanks for asking." Alya spoke annoyedly.

"I'm sorry. Hey, you're in the same grade as Alix, right? I'm her older brother, Jalil Kubdel. So you're into Tutankhamun too?" Before he could talk more, Jalil spotted his father and ran towards him. "Dad!"

"Weird. So again girl, why are we here? This exhibit's got something to do with Ladybug? For reals?" Alya asked Marinette.

"Well, uh..." Marinette stutters, but she quickly looks at the Egyptian papyrus. "Yeah, it's over there." She lead Alya and (Y/n) to it.

A few minutes have passed and Alya was beginning to get bored. (Y/n) tried to help Marinette find something about Ladybug. More minutes have passed and still nothing.

"Are you sure there's something about Ladybug, Marinette?" (Y/n) asked. "Could you tell me what it is?"

"No, no, cause... it wouldn't be a surprise then... for you or me." Marinette explained. (Y/n) looks at her confusedly and just shrugged her shoulders.

The three girls continued to try to find any clue that leads to Ladybug. but still nothing. As they continued their search, they saw Jalil talking to his father about Tutankhamun. He finished reading about the hieroglyphs; they said that there was a spell to bring back the princess, Nefertiti from the dead since the sun god Ra took her as his goddess. It would require exactly one hundred mummies and a new wife. Jalil pleads to his father to let him try to see if the legend is true, but Mr. Kubdel wouldn't allow it. Jalil tries to persuade his father to let him try, but his father gave him his final answer, no. Jalil became depressed and walks out of the exhibit. The girls couldn't help, but feel bad for him. They pushed the event back and continued their search. Marinette tries to figure out the significance of the symbols. Alya was beginning to get bored again, so she decided to take the history book out, but Marinette told her she found the secret about Ladybug.

"Marinette...I don't see anything about Ladybug." (Y/n) said as she yawns. "Look closely! It is in there." Marinette encouraged.

Their search was interrupted when a new super villain, Pharaoh. A museum employee tries to stop him, but Pharaoh summons his power. "Thoth, give me time!" His faced changed. He traps the bystanders in golden bubbles. Alya grins as she gets her phone out and runs off. (Y/n) quickly pulled Marinette to hide from Pharaoh. They tried to warn her to hide, but was she too distracted. Pharaoh ordered the bubbles to leave and they fly out of them room.

"Marinette, you go find place to hide. I'm going to find help." (Y/n) instructed as she ran off. "(Y/n), wait!" Marinette called out to her, but she was gone.

Once (Y/n) found a corner to hide, Bitz immediately flew out of her hair and floats beside her. "It's time to fight this ancient king!" (Y/n) smiled. "Bitz, fly in the night!"

(Y/n) begins to transform as Bitz enters her choker. It reveals a glowing bat with five pieces on it. (Y/n) crosses her hands over her face as she claps her hands together as her light purple suit morphs around her. She places her hands on her head as bat ears appear and putting her (h/c) hair in a high bun with two strip of hair in the front. A light purple, tessen fan that is similar to a bats wing appears in her hand as she slashes the air and poses with the tessen in front with her as her other hand was crossed over her stomach.

Alya began to whisper as she was recording a video on her phone. "OMG. Coming to you live, Ladyblog viewers, I'm at the scene even before Ladybug, Chiroptera, or Cat Noir! This is insane!

As Pharaoh steals the scepter and the papyrus, Ladybug and Chiroptera entered the scene.

"You know that's considered stealing." Ladybug smirks as she readies her yo-yo. "Actually, I'm taking back what rightfully belongs to me." Pharaoh said. "Ha! Maybe if you were the real Pharaoh, but you're not even close!"Chiroptera pulls out her tessen fan.

"Look at Ladybug go! If I'm dreaming, don't wake me up!" Alya continues to record. Ladybug and Chiroptera try to shoo at her. "They waved at me! No way!"

Ladybug uses her yo-yo to attack the Pharaoh, but he grabs the yo-yo and swings Ladybug away. He collides to a wall. Chiroptera attacks Pharaoh with her tessen fan, but he grabs her arm and throws her to the other side of the room.

"Sekhmet, give me your strength!" Pharaoh's face changes again.and he uses his new strength to bend the bars open. Suddenly, Cat Noir appears. "How nice of you to hold the door open for me!" He joked before he could attack Pharaoh. Unfortunately, he got caught and was thrown into a coffin. "Enjoy your coffin!" Pharaoh laughed.

Ladybug and Chiroptera went to the coffin to try to free Cat Noir. What they didn't realized I that Pharaoh has taken Alya hostage. Chiroptera told Ladybug to get Cat Noir out while she deals with Pharaoh. Before Chiroptera could made it towards Alya, Pharaoh punches back to her teammates. Ladybug was able to get Cat Noir out of the coffin and they all went to fight Pharaoh.

"Put her down!" Chiroptera demands. "Hiding behind an innocent bystander! You're weak, Pharaoh!" Cat Noir taunts. "I'm way more powerful than you are." He uses his strength to close the bars and walks away with Alya on his back.

"And don't forget! All the latest behind-the-scenes are on my blog!" Alya said nervously as she winked at them

"That Alya is one brave chick." Cat Noir comments. "You could say that again." Chiroptera laughs. "If by brave, you mean bossy, feisty, and bold? Yup, that's her! Come on, get us out of here, Cat Noir!" Ladybug exclaims.

"Cataclysm!" Cat Noir summons his cataclysm andcbreak the bars. "How are we gonna find them?"

"Alya's got a livestream on her blog!" Ladybug plays the video from her yo-yo screen.

"Hi, everyone! Alya here, liveblogging from the shoulder of the terrifying villain! Huge scoop to come, stay tuned!" Alya said from the video.

Cat Noir saw that his Miraculous was beeping. "You two go ahead. I'll join you as soon as my Miraculous is charged up again."

"Better hurry, CN. All three of us have to stop him." Chiroptera explains. She and Ladybug separate from Cat Noir in the search for Alya and Pharaoh.

Ladybug and Chiroptera stopped for a moment and watched what was happening in Alda's live stream. She was planned to be sacrificed in Pharaoh's plan to bring back Nefertiti.

"Hold on, Alya!" Ladybug said as she and Chiroptera continued their run, but they accidentally run into one of the time bubbles, trapping them. "Oh, no. We're caught in one of the time bubbles!" Chiroptera bangs on the bubbles. Ladybug tries to help her pop it, but nothing seem to work. "We've got to get out of this!"

They stopped when they heard Alya from the screen. "Ladybug, this is Alya! I just found out I'm the sacrificial offering to the sun god! Please hurry!"

"Hang in there, Alya. We're nearly there!" Chiroptera exclaims as they both try to run inside the bubble.

Cat Noir arrived just in time and uses his staff to bursts the time bubble the two heroines were trapped in. He caught them just in time. "Thanks for waiting around for me, you two!"

"More like thanks for getting us out of that bubble trouble, CN" Chiroptera jest. "We've gotta find the hidden akuma and free it before he sacrifices that poor girl!" Ladybug said as they all ran off. They made it to the front door and saw the mummies waiting outside.

"I don't see her or Pharaoh." Ladybug said. "Lets try the roof." Chiroptera suggested. Ladybug and Cat Noir nodded her and made their way towards the roof. Once they've reached the roof, they have a clear view of everything. "Over there!" Cat Noir points. They went back to the screen on Ladybug's yo-yo as they watched the ritual was about to begin. They hear that there was a Ladybug goddess from 5,000 years ago.

"Everyone does have a past they can learn from." Ladybug said. "Well, you don't look a day over 3000. And Chiroptera looks too young to be ancient." Cat Noir compliments. Chiroptera playfully punches his arm. "Now you know why LB is much wiser than you."

Pharaoh began the ritual. "Oh, sacred Ra, god of the sun, I Pharaoh, offer to thee a pure soul! The sacrifice for the return of Nefertiti! I bow to you, and present this gift with my mummies! In company, we pray to you the safe return of princess Nefertiti! Awaken, Nefertiti! Awaken! Awaken, Nefertiti! Awaken!" The Louvre pyramid lights up as he speaks. It shoots a beam of light into the sky that starts spreading darkness. Alya cries for help as she was taken by the mummies to be sacrificed.

"We've gotta save her before he completes the ritual, or Alya will be gone, forever!" Ladybug explains. "So what's the plan?" Chiroptera asked. "You and Cat Noir hold back the mummies while I take on the Pharaoh." Ladybug instructs.

"Why do we have to deal with these freaks while you get to slip calmly round back?" Cat Noir complains. "Because I'm the only one who can capture his akuma, and because you are the bravest one out of three of us!" Ladybug winks at him as she swings away. "Sure. I know you don't really think that, but I'll pretend you do." Cat Noir said as Chiroptera playfully elbows him.

Cat Noir and Chiroptera leaped down and called out to the mummies.

"Hey there, you bunch of bandages! What do you say we wrap this up!" Cat Noir jokes. "Nice mummy joke, CN." Chiroptera compliments. "Cat Noir! Chiroptera!" Alya calls out. "Seize them!" Pharaoh commands as the mummies run after them. "Is that really as fast as you can go?" Cat Noir asked. "I guess this is why mummies are so slow." Chiroptera smirked as she and Cat Noir leaps from lamp posts.

As the mummies were distracted, Ladybug took this chance to rescue Alya. Pharaoh suddenly realized that it was a trap.

"Horus, give me your wings!" Pharaoh's mask changed and he soars into the sky.

Once Ladybug as put Alya on the roof so safety, Alya began to thank her told her where the akuma is hidden. Inside Pharaoh's pendant. Right before Ladybug could think of a plan, Pharaoh suddenly appeared and her off the roof, but she uses her yo-yo to land safely.

"Way to go, Ladybug!" Alya cheers, but stops when Pharaoh lands behind her and throws her phone away. Luckily, Ladybug caught it just in time. "You're not going to win this time, Ladybug!" Pharaoh flew near her as he held onto Alya . "Help me, Ladybug!" Alya struggles to get lose. "Crush that insect!" Pharaoh commands as the mummies surrounded Ladybug. She witnesses Alya being thrown onto the beam of light and carried upward.

Chiroptera was able to get away from some of the mummies, so she used her opportunity to summon her power. "Echo!" Chiroptera summons her power. She throws the glowing orb and saw wave signals only she could see. She saw the mummies were going to crush Cat Noir with a vehicle.

"Cat Noir, watch out!" Chiroptera warns as she runs up to him. Cat Noir gasped when the mummies throw a car at him. Chiroptera tackles him away from the car just in time. "Thanks, Batty." Cat Noir thanked. "Don't mention it." Chiroptera said.

"Cat Noir! Chiroptera! This way!" Ladybug points at the bus as they both followed her. Ladybug and Chiroptera entered inside as the mummies follow them. Once they exited out, Cat Noir turns the bus on its side with his staff.

"We have to save Alya before she reaches the circle of darkness!" Ladybug exclaims as the three of them run towards Pharaoh and Alya. "You will not stop me from bringing Nefertiti back! I'll finish you off! Anubis, bring me mummies!" Pharaoh's mask changed and he begins to shoot beams at Ladybug, Chiroptera, and Cat Noir, but they dodge them. Ladybug uses her yo-yo to grab the Pharaoh, while Cat Noir and Chiroptera tries to rescue Alya.

"Horus, give me your wings!" Pharaoh flies into the sky and takes Ladybug with him. While airborne, Ladybug grabs the Pharaoh's pendant and drops it. "Cat Noir! Chiroptera! The pendant! That's where the akuma is!" Ladybug told.

Before they could reach it reach it, Pharaoh lands near it. "Sekhmet, give me your strength!" Using his strength, Pharaoh makes a sonic wave that knocks Ladybug, Chiroptera, and Cat Noir off by clapping. Soon the mummies surround the heroes.

Pharaoh grabs the pendant and walks over to his ritual as Alya gets closer and closer to the dark circle. "It's over. Oh, Ra, god of the sun, accept this humble offering and return the princess to ME!"

"Lucky Charm!" Ladybug summons her power and a costume appears. "A Ladybug outfit?"

"That's our last hope?" Cat Noir and Chiroptera asked together.

Ladybug began to think of a way to defeat Pharaoh and only the earrings in the costume appear. "This offering isn't good enough for Nefertiti!"

"Hey! Thanks a lot!" Alya grumbles. "Too late, Ladybug! The ritual has begun!" Pharaoh told. "Set Alya free and sacrifice me instead! Wouldn't that be the sweetest revenge? 5000 years later! After all, I'm the one who kept Nefertiti from you all these years!" Ladybug offered. "It's true that you make a much more precious offering than this mortal." Pharaoh accepts her off and takes Ladybug's hand. "Horus, give me wings!" He flies with Ladybug up to Alya and throws her off the beam. She falls off, but Chiroptera was able to catch her. "Excuse you, but I make excellent sacrificing material!" Alya pouts. "I don't think you want to be scarified." Chiroptera chuckles.

"You win, Pharaoh." Ladybug pretends to take off her earring, then tricks the Pharaoh and grabs his pendent. "You want my Miraculous? Go get it" She throws the fake earrings.

"Pharaoh grabs them, but saw that they're fake. "A toy? You tricked me!" Ladybug punches the pendant which breaks it and it releases the akuma. She was able to slide down from the pyramid and lands on the ground. "No more evil doing for you, little akuma. Time to de-evilize!" She catches the akuma. "Gotcha!" Ladybug released the butterfly from her yo-yo. "Bye bye, little butterfly. Miraculous Ladybug!" She throws the Lucky Charm into the air and everything turns back to normal.

Pharaoh turns back into Jalil. "What happened?"

Chiroptera and Cat Noir walked up to Ladybug as she gives Alya her phone back. Chiroptera saw that she was about to transform back. "I guess I run off before I change back. See ya, guys!" She leaps away and back into the museum to transform back into (Y/n).

Back inside the Louvre., Alya walks back to the exhibit and saw Marinette and (Y/n) running towards her.

"Where have you two been?" Alya questioned. "You won't believe this! I got mummified!" Marinette explained. "Same here! I thought I'd be a mummy forever!" (Y/n) joins in.

"Hope you both weren't one of the ones trying to swap me for Nefertiti! Creepy!" Alya comments. "Wait?! You were almost sacrificed? Sorry about that Alya." (Y/n) said sheepishly. 

"If it hadn't been for Marinette I'd never have found out that Ladybug is at least 5000 years old!" Alya exclaims. "Well that's something I've learn today." (Y/n) giggles. "Hey! What are friends for?" Marinette smiled as she walks out as her friends followed.

"I still don't get it though, what was she doing with that tenth grade history textbook?" Alya questioned. "Maybe she wanted to learn what has happened after 50 centuries." (Y/n) hypothesized. "That could be it." Marientte agreed. "You're probably right. It's tough staying in the loop. Hey, Ladybug's textbook! It's gone!" Alya stopped as she went through her bag. (Y/n) saw Marinette giggling to herself. (Y/n) found herself smiling at her friend.

Back in her dorm, (Y/n) was looking through her history book as she was studying about ancient Egypt. Soon her eyes came across to the hieroglyphics. She looked closer and saw the Egyptian Ladybug.

"I still can't believe there was another Ladybug from ancient Egypt." (Y/n) said as she turned to Bitz. "Does that mean Kwamis could live that long, Bitz?"

Bitz nodded his head. "Me and other kwamis have been around longer than ancient times."

(Y/n) smiled. "Did you meet other people who became a bat heroine like me?" Bitz giggles. "I've met a lot of people who held the bat miraculous. Each and every were special in their own way. Just like you." Bitz nuzzled to (Y/n)'s cheek. (Y/n) chuckles as she held Bitz closer to her. "Thank you, Bitz. And looks like Ladybug was lying about being older than me and Cat Noir. I have a feeling that I know her from somewhere."

Bitz gives her a worried looked, but quickly calmed down when (Y/n) stroke his head. "And if we do learn each other's identity, I'll make sure nothing happens to my friend. After all, I do view LB and CN as my friends." (Y/n) continues her studies as Bitz lays down on her head watching her study.
