Dr. Katherine Kalama is Noriko Null's personal physician.
Dr. Kalama was a doctor in Honolulu who treated Noriko Null after she regained control from Abyss. Impressed by her skills, Noriko hired her as her personal physician. Despite Noriko being an extremely difficult patient that keeps getting herself in trouble, the doctor became her confidante and friend. She even accepted Dr. Kalama as the girlfriend of Bob Null.
Noriko learns that Dr. Kalama is pregnant after she and Bob received a bottle of Dionysus wine from Viper. She gives birth to Noriko's half-sister Nalani a few months later.
Dr. Kalama is a human with no powers.
