Chiyoko belongs to a traveling troupe of five musicians from Ōshima Island: one man and four women. She is the wife of Eikichi, the male leader of the group. Her mother also travels with the troupe as part of their touring party. The complete troupe comprises Eikichi, his wife Chiyoko, his mother-in-law (Chiyoko's mother), his younger sister Kaoru (the titular dancing girl), and a maid.

Journeying through the Izu Peninsula, Chiyoko travels and performs alongside her family at inns and villages, earning income before the onset of cold weather. Within the group's established social dynamics, she participates in conversations, such as those acknowledging the kindness of the student protagonist. These interactions contribute to the protagonist's emotional shift away from melancholia. Chiyoko is part of the collective experience fostering his sense of connection. Her individual actions or dialogue remain defined by her role as Eikichi's spouse and a member of the performing ensemble.

Her presence and role across all documented adaptations, including films, television dramas, and animated versions, remain consistent with the original narrative depiction: a supporting member of the troupe without additional narrative focus or personal character development.
