Yohko Sakurano serves as the younger sister to main protagonist Tazusa Sakurano. Following their parents' divorce, she resides alongside Tazusa and their coach Yūji Takashima in a shared household. Demonstrating a level-headed and practical nature, Yohko routinely handles domestic duties such as waking Tazusa for breakfast and maintaining household schedules. She consistently attends Tazusa's figure skating competitions, offering steadfast support and encouragement that provides familial stability against competitive pressures. While the original light novel series portrays Yohko as an active figure skater herself, this specific character detail remains absent in the anime adaptation.
