Ruri Tsukishima is a former actress, Kazuyuki's ex-wife and Riho's mother. During her youth, Ruri aspired to become an actress, obtaining minor roles at that time she would meet Yumiko and from that moment her career would end up being frustrated. Some time later, Ruri would meet Kazuyuki and meet his parents, meeting Yumiko again, despite that Ruri would marry Kazuyuki and they had a daughter named Riho. On a day off, Ruri and her family visited Miura where the family was staying, the three of them entered the cafe where they were served by Sachiko, during that day the three of them took a photo of their vacation. Riho would begin to become popular as young actress which would make Ruri change her personality and ask for a divorce to Kazuyuki, forcing him to pay child support until Riho turned 20 years old as well as not being able to talk or contact her until she was 20 years old. Over time, Ruri would become a hoarder, causing the apartment she lived in to become filled with bags full of objects. At some point she was diagnosed with terminal cancer, although with the help of Kazuyuki and a long recovery she was able to overcome the disease. After leaving the hospital she would move in with Kazuyuki. Ruri has a superior sense of taste that only 25% of the population has. (Source: Goddess Café Terrace Wiki)
