is the second protagonist of the series. She is a beautiful, 22-year-old widow who takes on the task of managing a broken-down boarding house. She lives in the manager's room (with no room number, a reference to the 無 in her name meaning "zero" or "null"). She is sweet and polite, but she also has a violent, frightening side that emerges when she is jealous or angry -- a trait she has in common with other Rumiko Takahashi heroines, e.g., Akane Tendo (from Ranma ½), Lum Invader and Shinobu Miyake (from Urusei Yatsura), Sister Angela (from One-Pound Gospel), Kagome Higurashi and Sango (from InuYasha) -- or dealing with her meddling parents. She soon develops affection for Yūsaku, and has a tendency to dote over him (the other tenants tease her for acting "like a good wife") and sometimes becomes jealous around him (though she denies it is jealousy). However, it is hard for her to forget about her late husband "Mr. Soichiro" (Soichiro-san, who died just six months after the wedding), and her memories of her husband sometimes put her in a melancholic mood. Kyoko's love for him is sometimes reflected in dialogues with her dog, who bears the same name as her late husband. She is two years older than Godai and a widow is one of the many worries she has later on about whether she will be accepted as his fiancée, she was born in 1958. At the end of the manga and anime she is happily married to Yusaku and mother to their daughter Haruka.
