Princess Sofia is a girl of humble origins who lives with her mother Miranda. She becomes royalty after her mother's remarriage to King Roland II. Being new to the entire princess legacy, she had hard times understanding other princesses, and act like one. Despite her cuteness and sweetness, Sofia is rather clumsy but has a pure heart. Since she was originally a mere commoner, she retains a very carefree personality, and was once seen to enjoy sliding down the rails of the staircase. Her behavior often puts her at wits with her stepsister Amber, who's apparently jealous of Sofia.
