Plum Risch (プラム・リッシュ) is Kadomon Risch's daughter.
Plum typically wears a pink dress with a small ribbon attached onto it. She has her bright green hair styled in a bob style haircut and light blue eyes.
Being a young child, Plum is easily scared when separated from her parents. Despite this, she is quite cheerful, easily warming up to Emilia and Subaru while they helped find her mother.
