Yuriko Hori, born Yuriko Koyanagi, is Kyousuke Hori’s wife and mother to Kyouko and Souta Hori. She possesses a tall stature, long brown hair, and olive eyes, though some adaptations depict her hair with a lighter shade. During high school, she bore a striking resemblance to her daughter Kyouko, frequently styling her hair in a low ponytail or wearing it down with face-framing bangs. Her personality blends gentleness with a firm core. As a caring, hardworking mother, her demanding career often limits her time at home, leading Kyouko to handle household duties and Souta’s care. Yet when present, she prioritizes family moments and warmly welcomes Izumi Miyamura as part of their circle. Beneath her calm exterior lies an uncompromising resolve, once demonstrated when she slapped a harassing student in her youth—a trait Kyousuke termed "thorns" beneath her flower-like demeanor. She avoids extensive cooking, with curry standing as her sole kitchen specialty. Yuriko married Kyousuke after their high school acquaintance. Her maiden name, Koyanagi, meaning "small willow," reflects eastern Japanese naming traditions. The name Yuriko, translating to "lily child," mirrors Victorian flower symbolism linking lilies to love and familial warmth—qualities she embodies with her family. Her career-driven absence remains a consistent influence on household dynamics.
