She worked with Godai at a liquor store and first appears in ep 12 when Godai couldn't find anyone to go with him to watch a movie since he had two free tickets, one of which was meant for Kyoko. She seems to have had a love interest for him since when they worked together.

Maison Ikkoku is a romantic comedy series created by Rumiko Takahashi. The story centers around the development of the relationship between Kyoko Otonashi and Yusaku Godai. Kyoko is a recent widow who moves into the apartment house Ikkoku-kan where she becomes the manager. Godai is a wanna-be student ("ronin") struggling with college entrance exams. 
When they meet, it's love at first sight&mdash;for Godai anyway. Along the way, the other tentants, the mysterious Yotsuya, the seemingly alcoholic Ichinose, and the brash Akemi, watch and occasionally take part to make their lives more interesting. To complicate matters further, the wealthy tennis coach Shun Mitaka has his eye on Kyoko, while Godai is pursued by both Nanao Kozue and Ibuki Yagami. Covering a wide range of emotions from hysterically funny to painfully sad, Maison Ikkoku&mdash;all 96 episodes&mdash;is well worth seeing.

Her true name is Yoshiko Masumoto (増本美子) and her maiden name is Tominaga (冨永).  She works for mint Avenue.

Travel into Japan's nuttiest apartment house and meet its volatile inhabitants: Kyoko, the beautiful and mysterious new apartment manager; Yusaku, the exam-addled college student; Mrs. Ichinose, the drunken gossip; Kentaro, her bratty son; Akemi, the boozy bar hostess; and the mooching and peeping Mr. Yotsuya. Funny, touching, and a tad off-kilter, Maison Ikkoku is the great Rumiko Takahashi at her very best.
