Kozue Sengoku belongs to the extended supporting cast of Horimiya, surfacing chiefly through her family ties rather than through scenes of her own. She is married to Takeru Sengoku and raised their son Kakeru, and the series later frames her as a grandmother once the next generation arrives.
Horimiya offers little dedicated description of how Kozue looks, presenting her simply as a grown woman within the Sengoku household. Her design appears in connection with her relatives more than through any standalone spotlight of her own.
The story spells out almost nothing about Kozue's temperament. What it does establish is her steady place as a wife and mother, a quiet anchor in the home where her son Kakeru grows up.
