Manon is rambunctious, energetic, stubborn, and naive. She loves to have fun, but she doesn't like it when people don't keep their promises or are being unfair — whether it's in her eyes or it's true. She's also a bit spoiled and capricious, getting angry when she doesn't get what she wants, and she can be disobedient at times to her mother or her babysitter. She sometimes tries to use puppy eyes to win others over, although it doesn't always work, but while she gets emotional about things she doesn't like, over time, she usually recovers from it in normal circumstances.
