In class Nathinel was doodling about him being a hero who saves his crush Marinette when the teacher, Ms. Mendeleiev caught him and sent him to the principal's office but before he could reach there he tripped and sent his art book flying. Chloe picked it up and said "Look he drawn himself as a superhero who was saving his crush which is (looks at art book) Dupain-Cheng!" She then laughed at this causing Nathinel to grab the notebook and run out of class. He turned into an Akuma. Later Nino, Alya and Adrien are working on their project together in the library when they heard a commotion, when they went to the source. They found Nathinel Akumatized and hurting Chloe with a hairdryer, Adrien snuck away and transformed.
Cat Noire and Ladybug arrive on the scene, Ladybug ties her yo-yo around the hairdryer and then rides it like a cowboy while Cat noire battle the Evillustrator (Nathinal's Akumaed form, dubbed by Alya), he drew sawblades and lanced them at Cat Noire who hit them one at a time with her staff while coming closer to the Evillustrator who put up a wall. Which Cat Noire joined by Ladybug who has destroyed the giant hairdryer just went around only to find him escaped through the floor via erasing the floor and then after jumping down into the underground of the school, he created floorboards to block his escape route. Causing Cat Noire to say "Cataclysm1" Destroying the boards with her power then Ladybug said "Lucky Charm!" Which produced a flashlight, they then went underneath the school. They (with the help of the flashlight) found the Evillustrator and shined the flashlight in his face causing him to block the light with his drawing board, he tried to create a saw blade to attack them with but found he couldn't create anything as it was too dark. Cat Noire and Ladybug toke advantage of that by Ladybug tieing him up with her yo-yo and holding him in place while Cat Noire went to grab his Akuma object and snapped it in half.
Marinette tried to get Sabrina to see what a bad influence Chloe was but Sabrina wouldn't listen as she said "You abounded me in my time of need, at least Chloe had the excuse that she was being attacked by the villain. Sorry but I won't be your friend, I'll stick with Chloe. Thank you very much." Sabrina and Chloe then left Marinette.
