Maria is a gentle girl who likes to move at her own pace. She adores cute things, such as Sanrio characters and decorated sweets. She enjoys attention and can sometimes come off as selfish because of it. She adores her childhood friend Hikaru, who she calls “Hi-Chan.” They often play house together, where she is the mother and Hikaru is the father. However, because a single father is raising her, she doesn't know what is considered "motherly" and has to be corrected by Hikaru.
