Ruriko Matsunai

She is the latest idol-singer that is being produced by LME and is about the same age as Kyoko. She is introduced in chapter 8 when she tells Kyouko (who has become the new Love-Me trainee) to come with her to a movie production. Ruriko is very bratty and spoiled and uses Kyouko like Sho did by making Kyouko believe that is a very fragile and sick person. But when Kyouko discovers what she's been doing, Kyouko decides to take revenge on her by trying to steal Ruriko's role in the movie. (Source: edited from Sweet Revenge, skip beat fan site)
