As part of a ceremony for raising princesses on Planet Amanga, Shiima was taken from her mother as a baby and raised by Uba, a Space Beast who possessed milk to help her grow up. Due to not having any connections with her mother, she became cold, emotionless and without any pity or love that would typically exist due to a mother's love, thus making her the perfect general for Bazoo's army. However, some of her accusations appear to be a lie, with some of her memories displaying having a happy, normal childhood even with her training to be queen.Ep. 4: A Kiss After the FightEp. 12: Mama is MermaidEp. 46: Beautiful Shiima!
