Appearance
Rina appears as an attractive woman with pink hair and red eyes. She wears a gold-colored tube top. In her original sprite, Rina has a visible red star tattoo on her exposed midriff as well as a skirt. In the Alchemist sprite, Rina's midriff is covered and she wears a key necklace not present in her original sprite. Neither the red star tattoo nor the key necklace are present in her second Alchemist sprite. In her second Alchemist sprite, Rina also wears pale pink jeans.

Personality
As a deceitful scammer, Rina acts as a sweet, friendly, and loving person, to hide her ruthlessly manipulative nature. Driven by money, she uses her sex appeal to obtain it and gifts from men she primarily meets as a hostess or through her partner Teppei. Along with directly eliciting money and gifts from her marks, she runs loan sharking, "the badger", and other intimidation scams with Teppei. In Tsumihoroboshi-hen Rena realizes that Rina is both a great listener and comforter who can easily gain trust, including Rena's father's. Although Teppei's violence is considered to be the essential part of the badger games, Rina seems to be more intelligent than her partner and often creates her plans without informing him. Despite her shrewdness, Rina also appears to be rash, as she easily involves herself in exceptionally dangerous and risky actions, like stealing the funds of yakuza. While she may appear to depend on Teppei to provide the threats, Rina has no qualms about resorting to violence herself. When she meets Rena at Dam Construction Site, she confessed that she had "hoped" she would not have to kill Rena, but it is clear she was always prepared to do so.
