Everyone was in Ms. Mendeleiev as she was teaching her lesson. (Y/n) sat next to Rose as they were writing down notes. Sometimes they would share notes if one was confused about the lesson. As class continued, (Y/n) saw her friend, Nathaniel was drawing again in his sketchbook. (Y/n) was about to whisper to him, but Ms. Mendeleiev beat her to it.

"Nathaniel! What are you drawing?" Ms. Mendeleive questioned. Nathaniel stuttered at her. She grabs his drawings. "And these artistic endeavours are clearly why you are failing science."

"I'm sorry..." He apologized. "You go march yourself down to the principal's office and show him that checked scratch! Then you'll be really sorry!" She orders. Nathaniel grabs his stuff, but before he could leave he trips over Mylène's bag, dropping his sketchbook.

Chloé grabs it. "Ooh! Look, Sabrina! It's him as a superhero! And look who he's saving! It's Marinette! He's so totally crushing on you, Marinette!"

"Chloé, leave him alone!" (Y/n) stood up for her friend. "Gimme that!" Nathaniel grabs his book back. "Enough! Nathaniel, go!" Ms. Mendeleiev orders again.

After Nathaniel left, Ms. Mendeleiev told the class that they will be working in groups. The groups were Nino, Adrien, and Alya. The second group was Rose, Myléne, and (Y/n), and the last group was Sabrina, Chloé, and Marinette. (Y/n) felt bad that one of her best friends has to deal with Chloé.

Chloé raised her hand. "Uh, Miss, can't you add her to another group? Sabrina and I work much better on our own."

"This is a group presentation, not pairs! Deal with it." Ms. Mendeleiev remarked.

"I hate dealing with it!"

Class had finally end. (Y/n) walked towards Marinette and Alya. She pats Marinette's back in comfort. "You two wouldn't be willing to trade groups, would ya?" Marinette asked hopefully. "And deal with that twosome terror? Sorry." Alya said. "I'd rather fight a great white shark than deal with Chloé." (Y/n) comments. Alya steps in. "But I promise to talk all about you in between particles and the physics!"

"You're the best!" Marinette hugs Alya.

In the Library, (Y/n) was working on her project with Rose and Myléne. They're each using a book and their electronic to write notes. after that, they were discussing which parts of the notes would be used in the presentation. No surprise is that they agreed on everything on the project and their was no problem. As they were continuing working on their project, they could hear Chloé arguing with Sabrina. Apparently, Sabrina refuses to do Chloé assignment. 

"I don't know if I should feel bad that Marinette is part of Chloé's group or be proud of Sabrina that she's finally sticking up for herself." (Y/n) spoke. "I'd so say both." Myléne said. "I second that." Rose nods. 

(Y/N) went to get another book to help them more for their project. She entered into an empty section as she search for the right book. Her concentration was disrupted when she heard someone screaming. (Y/n) views from behind the book shelf and saw that Chloé was being chased by a giant hairdryer. (Y/n) covers her snickers as she hides behind the book shelf again. Bitz flew from her hair. 

"I don't know if I should find that funny or not." (Y/n) snickers. "Well, it is a bit funny." Bitz agrees. (Y/n) clears her throat. "Okay, no more laughing. It's transforming time! 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.

Chloé has run into a corner. "No! Stop!" Just in time, Ladybug arrives and jumps on the hairdryer. Chiroptera leaps in front of Chloé and pulls her away from the giant hairdryer. "Run and hide!" She orders as Chloé runs off. 
Cat Noir suddenly arrives. "I got wind that you were being blown away by a hairy situation." 

"Not the time to joke, CN" Chiroptera said as she helps Ladybug. It was a small struggle at first, but the trio was able to stop the hairdryer and disintegrate it. Cat Noir spots the new villain. The Evillustrator. "Well, that guy looks pretty sketchy!" 

The Evillustrator rans off as the trio runs after time. Before they could catch him, he draws a glass wall as the heroes collide into it and he disappears. 

"Dang it! Where did he go?" Chiroptera punches the wall. "I don't know, but he sure has a way of illustrating his point." Cat Noir makes a pun. Ladybug and Chiroptera groan in annoyance. 

After the whole library fiasco, the three heroes were back with Chloé in the hotel. Right now they were questioning her on why the villain attacked her. "Seems this Evillustrator's targeting you specifically, Chloé. Any idea why?" Cat Noir questions. "No. Everyone adores me." Chloé answers. "Yeah, because you're sooo adorable." Ladybug said sarcastically as Chiroptera silently snickers. 

"Yes! Ladybug just said I'm adorable! I totally need a picture of the two of us together!" Chloé takes a picture of her and Ladybug with her cellphone. Ladybug moves away from her. "Ugh! That was unpleasant." 

"Well, I look great, of course, but your smile is all wonky. I'll take another!" Chloé takes another picture. "Sorry, I'm just a little camera shy." Ladybug moves away from her. "My, my, my. You certainly got yourself a fan, LB." Chiroptera smirked. "Yeah, great." Ladybug crossed her arms. "So what's the deal? Why are you acting so weird? Come on, you gotta admit that having this girl worship you is pretty awesome." Cat Noir said. Ladybug and Chiroptera saw the drawing that Nathaniel has made, but it was ruined by Chloé. Chiroptera glares at her, but she didn't noticed. "Ugh, seriously? I'm over this! Let's go!" Ladybug walks outside. "Fine with me." Chiroptera shrugs her shoulders in agreement. "Are you kidding me? And what if the Evillustrator attacks her again?" Cat Noir knowledges the consequences if they leave. "Fine! You stay! Later!" Ladybug snaps. "What do you mean later?" He questions. "I mean, you're the one who wants to protect her." Ladybug explains. "Besides, I also have something better to do and you don't need us." Chiroptera adds. "So, later!" The two heroines left Cat Noir with Chloé. 

Chrtoptera reaches towards the slightly opened window of her dorm room. She fully opens it and enters inside. "Bitz, sleep in the day." Chiroptera transforms back into (Y/n). She signs as she collapses into her bed. She grabs her pillow as she groans. "Last time it was Alya and now my good friend, Nathan." (Y/n) groans. 

"Chloé needs a new hobby since her old one involves making other people miserable." Bitz flew into of (Y/n)'s face. "You said it." She sat up. 

Suddenly, her window and a part of the wall was being erased. Bitz quickly hid behind on top of the book shelf. What surprised them that the Evillustrator has entered inside. (Y/n) gasped. "Nathaniel?" Evillustrator waved at his friend. "Hey, (Y/n). And its Evillustrator now." 

"Okay, Evillustrator. What are you doing here?" (Y/n) asked. 

"I can here for your help." Evillustrator said. 

"My help?" 

"Yes, I need your help. I know you make the best song lyrics since you and I share each other's work. I was wondering if you could help me write a song to Marinette?" 

Marinette? Right, (Y/n) remembered that Nathaniel has a crush on Marinette. She thought for a moment and Evillustrator begs for her help. She was fully convinced and agreed to help. She took out her notebook as Bitz continued to watch them. Evilustrator gave her information of how he felt and how he would describe Marinette. (Y/n) has enough to make a short song and in no time, she was able to finish it. 

"I hope you both like, Evillustrator." (Y/n) hands him the paper with the song. "Oh, thank you, (Y/n)!" Evillustrator hugs her as she awkwardly pats his back. She finds it weird to hug her akumatized friend. Once Evillustrator left, Bitz was able to come out from his hiding place. "I still can't believe that another friend is akumatized." Bitz said. (Y/n) sighs. "Now that he's gone, I've got to go find Ladybug and Cat Noir so I can tell them where he's going." 

"Bitz, fly in the night!" (Y/n) quickly transforms into Chiroptera and exits her dorm room. 

As she leaps from building to building, she pauses once she got a call from Ladybug. She answers by using the handle of her tessen fan. 

Cat Noir:  You can't just fly out of here and then decide to make cat calls, Ladybug!

Ladybug: I'm sorry, that was a call. But you can leave Chloé. I need you and Chiroptera to protect this girl instead. Her name is Marinette. Really cute, isn't she? The Evillustrator is in love with her, and promised not to harm Chloé as long as Marinette comes to his birthday party. While he's distracted, I want you to take him down.

Chiroptera: What about you, LB?

Ladybug: I'm going on... a very important secret mission. I'll catch up with you two later. Can you both  handle this alone?

Chiroptera: Not a problem. 

Cat Noir: Ha! Please! It'll be a cinch! 

After she group chat, Chiroptera makes her way towards Marinette's house. Once she was close, she spots her feline partner. They leaped towards a building near Marinette's home. They saw her outside taking to Sabrina. It started off okay until Sabrina started to compare Marinette to Chloé since she can't help her with the project. Sabrina grabs back the homework she's done for Marinette.  I can't believe I did your geography homework for you..." She walks away. Once she leaves, Cat Noir and Chiroptera appears in front of Marinette. 

" Whoo-hoo! I thought we were going to have to save you from that girl's claws. Get it? Claws? Hey, I haven't even introduced myself. I'm Cat Noir." Cat Noir  bows down and kisses Marinette's hand. Chiroptera rolls her eyes and bonks him on the head. "Excuse my feline partner. I'm Chiroptera. Nice to meet you." 

"Uh, yeah... I know! You both kinda save the day all the time and stuff...I'm Marinette! So... What are you two doing here?" Marinette asked. 

"Well, that birthday boy date of yours is bad news. But don't worry. You'll be safe with us." Cat Noir turns around. Marinette makes some faces and Chiroptera covers up her laugh. "That puts my mind at ease." Marinette stops. "In order for you to be safe, we need your help to defeat the Evillustrator. Are you up to it?" Chiroptera asked. Marinette turns around. "What about Ladybug? Aren't you a trio?"

"She's busy with something tonight, so...You get to be our Ladybug." Cat Noir flirts. Chiroptera shakes her head at him. 
Marinette  turns back around. "Me, Chiroptera, and Cat Noir? Fighting crime together? Amaazing! What do I do?" 

"All you need to do if get his pencil away from him and we'll be able to take care of the rest. See ya later, Marinette." Chiroptera explains as she and Cat Noir jumps away. 

That night, Cat Noir and Chiroptera were leaping from building to building as they were getting close to the boat that Marinette and Evillustrator were on. Marinette was playing her role well as she continues to distract him. The boat was moving close to the bridge and it was the perfect opportunity for Cat Noir and Chiroptera to hop on board. They took out their weapons and walk closer to them, but they took a step back. What they didn't know is that Evillustrator noticed them.

"Marinette, give me my pencil back. I need to draw something, now!" Evillustrator demands. Marinette takes his pencil. "No, I'm keeping it! Cat Noir! Chiroptera! Now!" Cat Noir extends his staff in front of Evillustrator and Chiroptera leaped in front of Marinette to protect her 

"Marinette! You're working with them? I'm so stupid... I actually thought you liked me! But you're really just like Chloé. Teasing me, mocking me, leading me on!" Evillustrator yells. "Come on! Seriously? Why is everybody comparing me to Chloé tonight?" Marinette complains. "I feel so bad for you right now." Chiroptera said sympathetically. Evillustrator kicks Cat Noir's staff, and it hits the pencil. He grabs it. Just as Chiroptera and Cat Noir were about to strike him, he draws a transparent cube. It falls as it traps the two heroes and Marinette. 

"And I'm taking back my promise! Chloé's gonna get a little lesson she'll never forget!" Evillustrator erases a hole into the boat. It was beginning to sink as he escapes. 

Chiroptera tries to slash her way out from the cube. "Shoot! We're trapped!"

Cat Noir even tries to break it down with his staff. Marinette thought of a plan once she spots Cat Noir's staff. "Cat Noir, your stick! Like this!" She places the stick against the ceiling of the cube. "And extend it!" 

"Great thinking!" Cat Noir held both girls close to him. "Yeah...I'm a genius." Marinette adjusts his grip. Chiroptera does the same. Cat Noir extends his stick, lifting himself, Marinette, and Chiroptera. Once they were high enough, Cat Noir carefully lands back on the bridge. 

"Gotta go. A superhero's work is never done." Cat Noir counts on his fingers. "Damsels in distress, ladies in waiting... I've got a lot more saving to do. You can thank us later." He jumps away. 

"I think we should be thanking you. If it wasn't for your quick thinking we could have drowned. Thanks again, Marinette." Chiroptera bows. "No problem, Chiroptera." Marinette smiles. "Take care, Marinette!" Chiroptera gives her a two finger salute and leaps after Cat Noir. 

Cat Noir and Chiroptera made it to Chloé hotel room and what a surprise is that Ladybug made it  before them. She saves Chloé from a giant high heel by braking the heel and it disappears. 

"Oops! Broke your heel! Better watch your ankles." Ladybug jokes. Soon both Cat Noir and Chiroptera enters inside. 

"Glad to see you could join us again, LB." Chiroptera grins. "Glad to be back, Chiroptera." Ladybug said back. "So what was this secret mission?" Cat Noir asked. "If I told you, it wouldn't be a secret." Ladybug replied. 

"In the comics, this is what's known as the final showdown. The thing is, if you knew her, you wouldn't be breaking a sweat to save her skin! She's the real baddie!" Evillustrator announced his reasons to get even with Chloé. 

"Oh! It's not true! Everybody adores me!" Chloé remarks. 

"Not even close." Chriopters mutters. 

"Echo!" Chiroptera summons her power. She throws the glowing orb and saw wave signals only she could see. She saw Evillustrator draws four boxing gloves, and fires them at each other person in the room. The boxing glove comes at her and saw throws her tessen fan at it as it slashes into two and it disappears. She spots another boxing glove coming at Cat Noir. 

"Watch out!" She tackles him down as the boxing glove missed them. Ladybug dodges a boxing glove, and disintegrates another one with her yo-yo, as it also saves Chloé. The Evillustrator draws a wall to protect himself from Ladybug as she comes after him with her yo-yo. Chiroptera was about to strike him but, he  draws another wall. She falls back. Then he draws a buzzsaw, but Ladybug and Chiroptera dodges it. The buzzsaw is about to hit Chloé, but Cat Noir stops it with his staff. Once the buzzsaw disappears, he  splits his staff in half and throws them at the Evillustrator. He easily dodges them. A half of the stick breaks a lamp, so the Evillustrator gets closer to another working lamp. 

Ladybug gasped. "The light! Cat Noir! He can't draw in the dark!" 

"Got it!" Cat Noir saw the light switch and summons his power. "Cataclysm!" He was about to destroy the light switch, but the Evillustrator erases it and he breaks the wall instead. 

"Here you go, kitty.  A little ball and chain to play with." Evillustrator draws a ball and chain as they appear on Cat Noir's ankle. "Hey!" He yells. 

"Sadly, those who get in my way get erased." Evillustrator erases a giant hole in the floor. Cat Noir is about to fall into it, but Chiroptera gripped his arms just in time. Ladybug tries not to fall in. Cat Noir and Chiroptera could hear their miraculous beeping. "No, no, no, no, no!" Cat Noir exclaims. Evillustrator walks closer to the two hero. "Before you go, you both have something I want." 

"Hurry, Ladybug! I'm losing my grip on him." Chiroptera struggles to keep Cat Noir up. 

"Lucky Charm!" Ladybug summons her power and it gives her a small object. "A bouncy ball?"

"Just try and stop me with that, little lady!" Evillustrator laughs evilly. 

Ladybug begins to thinking of a plan. She saw the lights and lamps were the only things glowing and her plan was about to be put in action. "Gladly!" She throws the bouncy ball at all lamps, breaking them, as everything turns dark. She then drags the Evillustrator with her yo-yo, making him fall. With him down, she quickly grabs his pencil and breaks it. Once it's broken the akuma is released. 

Cat Noir hears his Miraculous beeps again. "Hurry!" Finally, the ball and chain disappear. Chiroptera was able to pull him out of the hole.

"No more evil-doing for you, little akuma! Time to de-evilize!"  Ladybug grabs the akuma with her yo-yo. "Gotcha!" The purified akuma is released. "Bye bye, little butterfly. Miraculous Ladybug!" She throws the Lucky Charm into the air, its energy repairing all the damage, and turning everything back to normal. 

The Evillustrator turns back into Nathaniel. "Huh? Where am I?" 

"Pound it!" The trio fist bumped 

The next day, everyone was back at school was everything was back to normal. (Y/n) was at her locker as she could hear Alya recording Chloé. 

"What happened when Ladybug, Chiroptera, and Cat Noir arrived on the scene?" Alya interviewed. 

"Well, to be perfectly honest, they only made matters worse. They came barreling in, and started smashing things to bits, throwing plastic balls around my room!" Chloé complained. 

"Plastic balls?" Alya was confused. 

(Y/n) chuckles as she grabs her items from her lockers. She pulls out an envelope out. She spots Nathaniel at his locker. She smiles as she makes his way towards him. She taps his shoulder. "Hey, Nathan." 

"Oh! Hey, (Y/n). What's up?" Nathaniel asked. (Y/n) gives him the envelope. "I know yesterday was your birthday and I tried to find you, but I couldn't. So, happy belated birthday." 

Nathaniel opens the envelope and it was a birthday card. Inside was a small song for him. "Wow, that's very sweet of you, (Y/n). Thank you." He hugs her. She hugs back as she was happy to hug her 'back to normal' friend. After that, (Y/n) went to go see if her best friend was doing okay after the whole Evillustrator thing happened last night. She saw Adrien standing behind Marientte's door locker. 

"Hey, Adrien." (Y/n) waved. 

"Hi, (Y/n)." Adrien waved back 

Once Marinette was done talking to Sabrina. She closes her locker door, but Adrien and (Y/n) startled her.

"I heard about your adventures with Cat Noir and Chiroptera yesterday. Were you scared?" Adrien asked 

"Me, scared? Pfft, it was a dream. I mean, you're a dream. I mean, in your dreams! Huh? Oh, this is a nightmare..." Marinette groans in embarrassment. 

(Y/n) laughs. "So what did you think of Chiroptera. How was she?" 

"Chiroptera? She was pretty cool and really nice." Marinette answered. This made (Y/n) smile. "What about Cat Noir? Was he awesome?" Adrien questioned. "I mean, sure! Yeah, but not as awesome as you, of course. Because, who could be? You're the most awesome of awesome." Marinette blabbed on. 

"So, that's a yes?" Adrien nods in satisfaction. The bell rings and he pats Marinette on the shoulder. 

"So you think Adrien is awesome, huh?" (Y/n) narrowed her eyes as she smirked at Marinette. "He touched my shoulder... I'll never wash my jacket again!" Marinette gushed. (Y/n) chuckles as she wraps her arm around Marinette's shoulder. "My best friend, you've got to control those emotions of yours." The girls laughed as they make their way to class.
