The Characters

The big sister

Wendy is Marine's big sister, 14 years old. A rebellious teenager with a soft heart, she loves teasing her little sister by calling her "pestouille", even though she loves her deeply. She regularly gets carried away by rock music, particularly her absolute passion — the band Les Vandalises.

The little sister

Marine is Wendy's little sister, 7 and a half years old. She's known for her remarkable cleverness, which shows in many episodes. Her passion for stuffed animals and princess costumes is obvious, but she has a genuine disgust for the idea of having a boyfriend — she finds it absolutely revolting.

The mother

Sandrine is the mother of Wendy and Marine, around 35 years old. She works as a nurse in a hospital, a job requiring rigour and composure — qualities she also applies to raising her daughters.

The father

William is the father of Wendy and Marine, around 35 years old. He works as a comic book artist, allowing him to express his creativity daily, which he also uses as an excuse to play around instead of working.

Wendy's boyfriend

Maxence, affectionately nicknamed "Maxou" by Wendy, is a secondary character in Les Sisters, 14 years old. He is Wendy's boyfriend and their friendship goes back to nursery school.
