A 15-year-old psychiatrist and member of the Dancouga team, she displays a surprising level of maturity for someone her age. However, she becomes easily annoyed if her name is mispronounced. She cares for the team's mental health, and like Tanaka, tries to answer their questions as best she can. Her name and character traits seem to be a play on Ruri Hoshino from Martian Successor Nadesico, and she makes a reference to this in one instance by saying something similar to Hoshino's favorite phrase.
