A new student, who is way worse than Chloé Bourgeois and Lila Rossi, is the cursed Inès Bennett. Not only she is spoiled while bullying people and lying about it, but she also has an abusive father who had assaulted her in her early years, which was where she grew her babyish attitude and why she wore a pale pink ribbon on her black half ponytail. When she was akumatized by Hawk Moth, it's up to Marinette Dupain-Cheng, known as Ladybug, and Adrien Agreste the mysterious Chat Noir, to save Paris from disaster.
"Good morning class, we have a new student who will be sitting next to Lila. Her name is Inès Bennett." Miss Bustier welcomed. The new girl appeared to be slightly younger than the rest of the classmates. She has shoulder length wavy black hair with a half ponytail tied with a pale pink ribbon, silver-gray eyes, and she wears a Sailor Moon inspired dress. She arrived to class late, and the teacher asked, "Dear, why are you so late?"
"Uh, uh, I don't know!" Inès bawled so hard that her speech was difficult to hear due to her misaligned buck teeth.
"Hey Inès, wanna be friends?" Lila lied.
"I would love to be friends. Besides, I had no friends in my childhood." Inès sniffed and also lied because she is too, a bully herself.
"Hey Marinette, did you know that even though Inès looks so cute in her kawaii outfit?" Alya whispered in Marinette's ear.
"Yeah…" Marinette responded. Even though Chloe was once spoiled and Lila lies, I would personally think that Inès will be way worse than both of them combined. There is something wrong with her after all.
"Today, we will be learning about the science of ladybugs." Miss Bustier continued teaching the students.
"Ladybugs? Oh my god, Mari! This is going on my Ladyblog!" Alya took her phone out.
Marinette warned, "Alya, not right now. Maybe we can update your blog later."
Seconds later, Nino whispered, "Yo Adrien, what's going in your head a lot lately?"
Adrien thought and just said, "Oh, nothing." Ladybug, my one and only supergirl. I need to discover who's under the mask.
After school, when Adrien was in his locker, Inès approached to him and flirted.
"Hey, baby. You must be the model of the city. Can I kiss you? I'll throw you a million!"
"Um… I don't have time right now because I have another photoshoot. Gotta go, see ya!" Adrien awkwardly stuttered, backing away from her. He thought, My heart only belongs to Ladybug. Chloé tries to flirt with me, but I don't like her. Yet I don't want to harm her. Lila gained my trust, but shatters it all so much I despise her. Kagami respected my boundaries while she's on a fencing tournament in Japan. But as I can picture Inès, she's such a crazy stalker and I'm terrified of her. I should've stopped saying "just a friend" to my one true love. On the opposite corner, Marinette was furious because she had a giant crush on Adrien, and now Inès bawled like a baby again, wanting to smash his face.
Tikki popped out of Marinette's bag.
"So Marinette, I know it's tough that the new girl wants to steal your man." Tikki insisted with concern.
"No, it's not that. It was because Inès is not only a spoiled brat or a liar, but also a crybaby. She did befriend Lila only to spoil and spill her tea and tries to win Adrien's heart just to have a ton of control over what she really wants." Marinette replied.
"Whatever I would recommend is to talk to her about the situation."
"Okay, but what if she harms me? She is going to get her dark lips on Adrien and her crusty feet on my face so that he will soon hate me and I will never pursue my dream about being a fashion designer and… I… I…"
"You're going to be fine, Marinette. Now just remember, I'm always going to be by your side, no matter what else happens."
"Thanks, Tikki. You're the best!"
When Marinette approached slowly to Inès, who was about to leave the lockers, she yelled, "Who are you?"
"I'm Marinette. Are you Inès?" Marinette nervously introduced.
"Uh-huh. Do you actually like this blond-haired boy? He's like the hot one in the class."
"You mean Adrien, right?" Adrien's supposed to be mine, not hers!
"Well, I wanted to date him so bad that I have suffered a very traumatic childhood and I need a sugar daddy to make me feel a whole lot better." Inès shouted with her buck teeth showing.
"I'm very sorry to tell you that he's taken. Also, please don't say that Adrien's a 'sugar daddy' because it's very inappropriate to describe him like this, so I hope you have a very nice day." Marinette turned her back and walked away to hang out with three of her friends Alya, Nino and Adrien. Inès was alone in the lockers crying again, throwing a temper tantrum and secretly wanting to also knock out Marinette and her kwami. But she remembered that her birthday party is in three weeks.
The next day came by after school and Inès invited her "friends". Lila even took one of the invitations. "I would love to come around!" Lila lied again, turned her back, and ripped the invitation.
Inès bossed around Marinette, "Make me a dress by my birthday or I will ruin you…"
"Okay, okay. You don't need to be very rude." Marinette backed away again, trying to calm her down. Inès walked straight to Chloé and Sabrina and bumped both of them. Lila was also involved.
"Oh, look. It's the crybaby and the liar versus us again." Chloé taunted.
"I know, right. She's 12 and still throws tantrums? That's so funny to prove that she talks and lies like a baby!" Sabrina added, chuckling super loud.
"No, it's my day and you're ruining it all for me! Don't try to assault me!" Inès mocked back, fighting back tears.
"Shut the hell up, hotshot! I don't want to be your friend anymore! I'd rather have no friends than befriend a big baby like you!" Lila spoiled the truth. "Also, Adrien's mine, not yours."
"No, he's mine!" Chloé grabbed Lila's hair as Lila broke Sabrina's glasses. Inès also pulled Chloé's sunglasses off when Sabrina gripped onto Inès's leg.
"I don't understand. Adrien's my sugar daddy. I just want to be better than you, so I don't give a damn and deal with it!" Inès also spilled her truth.
"Oh and what's your sugar 'daddy' going to do? Spank me?" Sabrina mocked.
"No, but I need to find him, you idiot!" Inès shouted.
"Excuse me, Adri-kins is truly mine! You're utterly ridiculous at using 'sugar daddy' for a small, dirty, and whiny hoe like you! I'm telling on you because you need to watch your language!" Chloé brushed off.
"Yeah, but face it, you'll never be big, and everyone in the world hates you." Lila screamed.
"Lie-la, this is all YOUR fault. Help me kick their mean little asses!" Inès threatened.
Marinette witnessed the four mean girls fighting. All of them are wrong. Adrien's actually mine. It's obvious to know that Inès is going to scare him off with her lies and crying habits. "Hey, all you kids! Stop fighting! It's never the answer!"
Adrien was about to leave after fencing classes, and when the girls fight, his jaw dropped. Plagg came out of his gym bag, "Well, looks like these girls are fighting for your relationship. Can I have camembert cheese? It's so addicting!"
"Okay, fine! Take one!" He handed him a piece of cheese. He looked around, ran over and screamed. "MARINETTE!"
The fight ended horribly with Lila having a sustained scar on her left leg and a right sprained ankle, Sabrina with a painful back and a broken arm, and Chloé with messed up hair and bites from her limbs. Only Inès was extremely unlucky. Her nose was bleeding; bruises from her visually damaged eyes were visible, her bones and skin are bloody and broken, including more loose and missing teeth, and worst of all, she fell down from a concussion after Chloé pushed her once into the locker, then the locker collapsed and hit her head. She was crying bloody tears when Marinette and Adrien disappeared.
Hawkmoth saw the screen of the poorly injured girl, and maliciously insisted, "Well, well, well. Let's see if this cursed child becomes more evil and get these brats what they unfortunately deserve after a pity party. All of her hopes will be released once I get my precious jewelry. Spectacular!" He caught a white butterfly and gripped it to curse it. "Fly away my little akuma, and evilize her!"
The principal dashed quickly to revive all four of the girls. Inès, who was still weeping hysterically, was unsuccessful when the black and purple butterfly akumatized her pale pink bow.
"Satinizer, I am Hawkmoth. You will have the power to not only turn the population of Paris into little ribbon bows for presents, but you need to give me the miraculouses inside one of them!"
"Yes Hawkmoth. Your wish is always my command." Inès angered, turning into Satinizer. The monster had ribbon hair of many colors, with her hair bow turned into a bright pink, pastel yellow and teal bow. Her eyes are red and her lips are bright pink. Her ribbon tutu dress also matches the hairpiece; topped off with ribbon flats and ribbon trimmed wings.
She used her hands to melt the doors and got herself out of the school. She flew and zapped them again, turning some people into bows. She also used the glue from her magical hands to stick them onto any building.
When Marinette returned home, her parents were gone.
"Mom? Dad? Where are you?" Marinette shouted with concern. She looked up on the window of her bedroom, noticing that a ribbon like creature zapped all of the citizens into decorative bows on the building. "Tikki, what is going on?"
"Someone's been akumatized! Quick! Transform!" Tikki warned.
"Tikki, spots on!" Marinette commanded, transforming into Ladybug.
Meanwhile at Adrien's house, Plagg burped after eating pounds and pounds of camembert cheese.
"Good ribbons! Looks like there's more gifts to give-" Plagg was interrupted.
"Plagg, claws out!" Adrien yelled, transforming into Chat Noir.
"Wait, no!" Plagg yelled and was trapped inside the ring.
Ladybug left her bedroom with her super flexible yoyo. She dodged and found out that the ribbon monster transformed Master Fu into a Chinese-themed bow, which makes him unable to take a sick kwami to his room. Chat Noir joined in with his baton, doing a track jump.
"Chat Noir," Ladybug shouted, "we need your help! Everyone's turning into ribbon bows in Paris! We need to stop her before she takes our lives!"
"Which one? Life A?"
"No time for your cheesy cat puns, kitty! Let's get to it!" Ladybug insulted as Chat Noir frowned.
So they ran away from Satinizer, who zapped her hands onto both of them, only to be protected by Ladybug's swinging yoyo.
Chat Noir escaped and threw a hiss at Satinizer, "Hey Rainbow Ribbon Girl! Are you knotty or nice? Where's Inès?"
Satinizer was in a rage, "Inès Bennett is dead. I'm Satinizer, not your typical rainbow girl! My ribbon bows, attack!" At the same time, she bursted into poisonous tears.
The ribbon people dashed to find Ladybug, yet Ladybug successfully escaped. However, she was unfortunate to find out that Chat Noir was turned into a grosgrain bow. Then Ladybug panicked as he was glued onto the school. "Chat Noir!" She also yelled, "Lucky charm!" The object appeared as she spun her yoyo up in the air.
"A pair of scissors?" She questioned. Satinizer continued to fight anyway, zapping more ribbon with her hands to Ladybug but was stopped when she did a somersault with a blade touching the pavement to cut them all off.
"No! This can't be!" Satinizer ranted. She still continued to zap colorful ribbons while Ladybug snipped them again. Meanwhile, Chat Noir yelled, "Cataclysm!" only to destroy the grosgrain bow he was stuck into. The snipping continued, and one of the strands from the villain's hair broke off. When Ladybug ripped the bow out of her hair and cut it into pieces, she used the broken hair strand to wrap a cocoon around Satinizer's body.
"Here, take this!" She commanded.
"Thanks, my lady!" Chat Noir added, "Her purr-fectly bow-tiful day will be ruined this way!" He used his cataclysm again to burn the pieces on fire. Satinizer yelled, "Nooooooooooo!"
"The butterfly! That's where the akuma hits!" Ladybug discovered and spun her yoyo once again. "No more evil doing for you, little akuma. Time to de-evilize!" She caught the evil butterfly inside her yoyo. "Gotcha!"
"Bye-bye, little butterfly." Ladybug whispered as the innocent white butterfly flies away. She threw her pair of scissors up with a "Miraculous Ladybug!"
The citizens of Paris turned back into normal people. The destroyed buildings were restored, there were no more ribbons stuck onto buildings. Satinizer turned back into her old self, lying on the road in a coma. Chat Noir wore out before the two heroes of Paris fist-bumped, "Pound it!"
"Where am I?" Inès said her last words.
"You got into a fight with three girls at school. Hawkmoth akumatized you by your hairbow, and you were turned into Satinizer." Ladybug's earrings zapped the last spot. "Oh, better transform back!" But it was too late when Chat Noir tried to run with her. They both transformed back into their normal selves simultaneously. They froze for a moment, leaving Marinette bewildered, "Adrien?"
"Marinette?" Adrien also got confused. Plagg asked, "Phew! That was a tough call! Wait… YOUR IDENTITY IS REVEALED! What were you thinking?" I can't believe that Marinette is my bugaboo!, Adrien thought.
Marinette thought, I can't believe that Adrien, the boy I have crushed on is the same guy behind Chat Noir! "Marinette!" Tikki spoke softly, "Why did you show your identity in front of Adrien? You know that…" Tikki looked up to Plagg, and she fell in love very fast.
"Tikki? Tikki!" Marinette blocked her kwami's view and tried to pull her away from kissing Plagg on his cheek. Oh snap, I can't believe Tikki kissed Plagg! And now he's blushing!
Later that night, Marinette looked away from her crush. Adrien patted her shoulder and asked her softly, "Hey bugaboo, what's up?"
"Nothing." Marinette responded.
"There must be something, what is it? Don't fear. I'm not angry." Adrien touched her loose hair.
"I- I had a crush on you ever since you walked out- I mean in the classroom. The umbrella memory was the most irresistible moment I had. Kissing you while you're leaving for a fundraiser party was another cute moment. But sadly in reality, I'm just this weird, awkward and messed-up girl behind the mask of Ladybug."
"But Marinette, that's not true!" Adrien paused. "I feel the same way too. I finally got some time to spend with you once again after dealing with my extremely tough life: modeling, fencing, piano and Chinese. This left me with no free time outside of school. As Chat Noir, I can finally feel the freedom to do what I want. With the dumb cat puns and the stuck up nicknames that seriously annoy you, it's my apologies. You are really amazing, talented at fashion, grateful to have your parents owning a bakery, and all of the positive things make you, you. Whether you're Ladybug or Marinette, I am forever your kitty and…"
"I'll always be your bugaboo." Marinette interrupted. They giggled together, and without thinking, Marinette kissed him on the lips. It was so soft like butterfly wings that Adrien slipped off the roof of his mansion and crashing onto his bed.
Three weeks later, the final scene ends when Inès was in the hospital waking up. Marinette offered her a cupcake and a dress she designed for only a short amount of time.
"Happy birthday, Inès. You deserve this special cupcake from my parents' bakery."
"Aww, thank you." Inès replied. As Marinette walked away, Inès smashed the cupcake and ate it with infuriation. "COCONUT? I HATE COCONUT!"
Then, she opened the box of the dress, and it had something weird inside. She sneezed at the feathers of the dress, and yelled, "DADDY! HELP ME!" She screamed and fell back asleep.
