People make the main characters too perfect so I made the main main character imperfect.
Name: Crystal (Surname)
Age: 15
Personality: A kind, shy, fun girl who has a somewhat dark side to her. She was bullied ever since she was little and kept to herself. Bottling her emotions and suffering resulted in Borderline Personality Disorder. She is pretty mature than most kids her age but she can be like a baby since she is the eldest of the three and was pressured into growing up too fast. She is a mystery. People would wonder what she was thinking or day-dreaming all the time. Her head is always in the clouds making her thoughtful.
Name: Cerelia (Surname)
Age: 8
Personality: An opposite of Crystal. She is hard-headed and jumpy. She is like a fashionista and is girly compared to Crystal being half girly and half boyish. But sometimes you can see that Cerelia is pretty sweet.
Name: Leo (Surname)
Age: 5
Personality: A mix of Cerelia and Crystal. He is sweet and funny.
