Paris

Chloé Bourgeois is the daughter of the mayor of Paris, a spoiled, capricious, and unpleasant girl. She is attracted to Adrien and hates Marinette.
Lila Rossi is Chloe's "friend," but she's actually using her to get in Marinette's way. Lila is much smarter and more cunning than Chloe, and she's also a very good liar.
Nino is Adrien's best friend and Ali's boyfriend. He's a kind and funny guy who knows when to make a joke.
Alya is Marinette's best friend and also Nino's girlfriend. She is a serious but sweet girl who knows how to support.
Luka is their friend, a nice and kind guy. He loves music and plays the guitar. He accidentally learned the identities of Ladybug and Cat Noir, but he doesn't talk about it.
So where are the rest of the friends:
girls: (Rosie, Milek, Kagami, Zoe)
guys: (Felix, Nataliel, Mark, Kim)

Hawk Moth is Gabriel Agreste, Adrien Agreste's father. No one knows he's Hawk Moth, and no one knows why he needs the Ladybug and Cat Noir talismans. If you combine their talismans, you can make any wish, but that would require a sacrifice, and it could all lead to chaos. But despite everything, he desperately wants to bring back his wife, Emelie, who also happens to be Adrien's mother, in this way.

Adrien is the son of the wealthy and famous fashion designer Gabriel Agreste. He's a friendly guy and also a model for his father. He's popular in several countries and is liked by a huge number of girls. He has a best friend, Nino. He bears the Cat Noir talisman, and his power is destruction. He only needs to say "catoclysm" to destroy anything he touches. In real life, he's quite shy, but as Cat Noir, he enjoys puns and various mischief.

Marinette is the daughter of the most popular baker in Paris; their bakery is famous for its delicious pastries. She's a kind girl, but very anxious and shy, afraid to confess her feelings to Adrien. For years, Chloé bullied her until Marinette learned to defend herself. She bears the talisman of Ladybug, a creature with the power of creation. Without her, it's impossible to defeat Hawk Moth, as he unleashes akuma on people with negative energy, which possess them and imbue them with evil powers. Ladybug's task is to find out what object the akuma is hiding in, destroy it, and most importantly, get rid of the akuma using a magical yo-yo. She can also restore wrecks and everything the villain has destroyed. Her best friend, Alya, is the only one who knows her secret identity.

You're a pretty girl, but you know your worth and can stand up for yourself. When you arrived in Paris, you knew nothing about the city, nor about its heroes and villains. Before arriving in Paris, you found a small box in your attic containing a beautiful diamond ring. It turned out to be a family heirloom, and you took it with you to Paris (this will change your life completely).
