Darkblade

"Darkblade" is the twelfth episode of the first season of Miraculous: Tales of Ladybug & Cat Noir. It premiered on February 28, 2016.

Synopsis
After losing an election, D'Argencourt gets akumatized into Darkblade and recruits the unwilling citizens of Paris into an army of knights.

Plot
The episode begins with Marinette jumping down into her room from the balcony, immediately detransforming from Ladybug. Nadja Chamack is on Marinette's computer, the news report relaying how Ladybug and Cat Noir saved the day. Marinette, on the other hand, pulls out a pink box worrying about not finishing it. Tikki asks what the box is for, to which Marinette replies that it will be holding her diary, the book that holds all of her secrets as Ladybug. Marinette sets the diary in the box with the lid open, telling Tikki to try and take it out. Tikki flies down and picks up the edge. Before she can fly out, the lid slams shut, locking Tikki inside. Marinette lets her out with a key.

Nadja Chamack switches to another news report, stating that the previous day, Mr. André Bourgeois was reelected as Paris' mayor for the fourth time. Marinette comments how it looks like it was Chloé who was reelected, prompting her to remember that tomorrow is the election for class representatives at Collège Françoise Dupont. Marinette has a problem with this because Chloé decided to run for class president, but is only doing it for herself and not the other students. Tikki suggests that Marinette run too, but Marinette feels as if she has too much to do between homework and saving Paris. The news report returns, bringing with it the face of one Armand D'argencourt, the fencing professor at the collège who lost to Mr. Bourgeois. Marinette rests her hand on her chin, watching the report until she sees the time in the corner of 8:44 am, knowing she'll be late to school if she stays any longer.

At Miss Bustier's classroom, Chloé and Sabrina are standing in the front of the students. Sabrina is running with Chloé as her vice president. Just then, Marinette runs in, her excuse being that she missed the bus and she has a cold. Alya brings Marinette up to speed, mentioning that Chloé has been the class representative since elementary school. Miss Bustier dismisses them for lunch, letting the class mull over its decision.

In the school's courtyard, Chloé threatens Kim before wandering off with Sabrina to threaten the rest of Miss Bustier's class. When Marinette asks Alix what Chloé told her, Alix mentions that she doesn't care and wonders why Marinette won't run. Marinette claims again that she's far too busy to run, thinking about her duties as Ladybug. Marinette then cedes that if no one else were to run, then she would.

Returning to Miss Bustier's classroom, Miss Bustier asks if anyone else wants to run against Chloé and Sabrina. Finding no opposition, Miss Bustier almost makes Chloé and Sabrina the class representatives, but Marinette interjects, stating that she'll run against Chloé and Sabrina. Excited, Miss Bustier tells Marinette that tomorrow, they will hold class elections. Marinette will need to have a speech prepared and campaign until then.

At another break, Marinette tries to come up with a platform to run on. Since Marinette had not thought this far ahead, her fellow classmates supply her with ideas. Alya perks up, spotting Adrien descending the stairs. She asks if Adrien will vote for Marinette, to which he responds that it all depends on her speech. This motivates Marinette further. Only meters away, Chloé and Sabrina observe their competition, Chloé mentioning she will win like her father always wins. Laughing, Chloé clarifies by stating that they are going to destroy Marinette's reputation and reveal her secrets.

Back in her room, Marinette lists what her classmates want in her diary, trying to come up with her speech. Then Marinette's cellphone buzzes, Alya appearing angry when Marinette picks up. Alya explains what Chloé is doing; Chloé invited the entire class to the Hôtel de Ville to meet Jagged Stone. Marinette begins fangirling since Jagged Stone is her favorite singer. Marinette realizes that Chloé isn't playing fair by buying their classmates' votes with autographs. Marinette leaves her room, leaving the diary box open on her desk.

As she runs out of the bakery, Sabrina steps around the corner, on her phone with Chloé. Sabrina walks in past the customers Sabine is waiting on, claiming she let Marinette borrow her math book and that she needs it back. Sabine explains that Marinette just left and since she is busy, she sends Sabrina up to Marinette's room.

Meanwhile during fencing class, Adrien was impressed after his coach made an amazing attack during his lesson. Mr. D’Argencourt then revealed to his student that the move was developed by his ancestor, Darkblade. He explained that how his ancestor once conquered Paris and ruled over it with an iron fist, before he was overthrown by a wealthy Frenchman. Nadja Chammack then appeared behind him so she could interview him about why he ran for mayor earlier. Irritated about his loss to Mr. Bourgeois and how everyone now takes him for a man obsessed with medieval times, Mr. D’Argencourt ended Adrien’s lesson and storms off.

Hawk Moth had senses Mr. D’Argencourt’s frustration that he sends an akuma after him. By the time he leaves the school, Nadja and her cameraman started following him around to get some more inside scoops about him. Mr. D’Argencourt angrily slashes apart a poster of Mr. Bourgeois when he bumped into it. Then the akuma arrived and possess his fencing sword. Mr. D’Argencourt sees his chance to be the city’s new ruler, so he is akumatized into Darkblade. Darkblade transforms Nadja and his cameraman into knights, so he could start forming his army to take over City Hall and reclaim his family’s throne. Adrien transforms into Cat Noir, as Darkblade continued to turn citizens into knights. By the time he arrived, he and his akumatized fencing teacher started to fight.

While all that happened, Sabrina got into Marinette’s room and was about to steal her diary. But the diary box closes down on her hand when she’s about to grab it. Marinette had arrive to City Hall and saw Chloe’s campaign launch party. She was angry when Alya got Jagged Stone’s autograph and not helping her for the election, but she’ll forgive her if she vote for her. Meanwhile, Cat Noir had lost the fight with Darkblade at the Pont des Arts when his staff got launch away from the bridge. But he manages to overheard Darkblade about going to City Hall to get Mr. Bourgeois while he hid under the bridge.

Back at City Hall, Marinette explains to her classmates that they’ve been bribed by Chloe to vote for her. But then her rival arrived and shows Marinette that she and Sabrina have her diary. Chloe said that they’ll blackmail her if she don’t leave the ballot. Suddenly Darkblade and his army arrived. They are about to get Mr. Bourgeois, but Cat Noir arrived just in time with his staff. Jagged Stone had mistake the battle outside for fans fighting over him, and got transform into a knight by Darkblade.

Panicked now that Darkblade is going to transform them into knights, Chloe can’t help her classmates unless they vote for her and she’ll found the solution the following day. Marinette knew that Cat Noir needs her help defeat the knights and her classmates are depending on her to protect them. Tikki explains to her to trust her instincts, so Marinette started leading her classmates to protect City Hall from being attack. But after they locked and barricade all the entrances, Marinette tells the mayor they have to retreat. With everyone out of the way, she turns into Ladybug and rushed to help Cat Noir.

Outside, Cat Noir had been surrounded by knights, but Ladybug appears just in time and get him inside with her yo-yo. As they worked together to fight off the knights, Darkblade turns two cars into catapults and launched themselves to the roof. Cat Noir and Ladybug got onto the roof and saw that Darkblade is about to place his family flag on top of City Hall. Ladybug knew that akuma must be in Darkblade’s sword, so they’re about to stop him. But Darkblade manages to plant his family's flag on top of the City Hall, and a dark cloud spreads over Paris. After the cloud stops expanding, it creates a circular black barrier on the extremity that shrinks inwards, turning everyone it passes through into knights.

Ladybug and Cat Noir knew that they’ll be turn into knights too. So Ladybug uses Lucky Charm, and a toy ladybug appear. Using her lucky vision, Ladybug tosses the toy under Darkblade’s shoulder, tickling him that made him toss his sword away. Ladybug grabs the sword, destroy it and the barrier, and reveals the akuma. She catches the akuma and purifies it. Ladybug then tosses the toy and cleanses the city, returning everyone back to normal.

By the time Ladybug got back inside and turns back to Marinette just in time, Tikki was proud of her for being Ladybug and a student leader at the same time. While the students removed the posters and chairs from the door, Marinette revealed to them that Chloe had stolen her personal item. As they surrounded Chloe and she tries to be innocent, Sabrina arrived to ask Marinette to free her right hand from her diary box. Alya had recorded Chloe with her phone to blackmail her and not having everyone vote for her. So everyone knew that Marinette would be the new representative. But Marinette explains to her classmates that she want to be voted in fairly, because they believe in her. She said she’s not gonna make promises that she can't keep, but she’s resourceful and know how to prioritize. And most importantly, she believe in herself too.

So the following morning, Marinette became the new representative and Alya became her deputy.
