Ruri Tsukishima is a former actress and Riho's mother. She was married to Kazuyuki, though they've since divorced.
Back when she was trying to break into acting, Ruri met Yumiko—an encounter that essentially derailed her career ambitions. Later, she'd cross paths with Yumiko again after meeting and eventually marrying Kazuyuki, and the two had a daughter together named Riho.
The family once vacationed in Miura and stopped by a cafe where they were served by Sachiko, snapping a photo to commemorate the trip. But things took a turn when Riho started gaining attention as a young actress herself. That success apparently shifted something in Ruri; she asked Kazuyuki for a divorce and made sure the separation included provisions requiring him to pay child support until Riho turned 20—plus a restriction barring him from contacting or talking to their daughter until she reached that same age.
As the years went on, Ruri developed hoarding tendencies, and her apartment became cluttered with bags of accumulated possessions. She was eventually diagnosed with terminal cancer, but with support from Kazuyuki and an extended recovery, she managed to pull through. After leaving the hospital, she moved back in with him.
Interestingly, Ruri possesses a refined palate—specifically, a superior sense of taste that only about 25% of people have.
