Katsuko is the therapist Ritsuka sees once a week. She is friendly and sincerely interested in Ritsuka. She tries to support him in telling him that he doesn’t need to worry about what his mother thinks of him, but it doesn’t seem to get through to him. She feels badly for Ritsuka, knowing that his mother abuses him, but is advised by her colleges not to get involved.
