The commander of the Kuromorimine Sensha-do team and the tank commander of the Tiger I. # Appearance She has short brown hair and brown eyes, with a face that is always expressionless and difficult to read. # Personality On the outside, she appears stiff, cold, and quiet. However, she is a compassionate and kind person who accepts everyone's opinions without rejection and has a side that subtly goes along with others' whims. She acts and speaks flexibly according to the situation in her own way. While she looks cold due to her lack of emotional expression, she is warm-hearted on the inside. # Characteristics She always wears the Kuromorimine uniform, so it isn't obvious, but she has zero fashion sense. She has no interest in dressing up and possesses not a shred of interest in dating or marriage. She finds dealing with men bothersome and difficult. Having lived in a girls' academy her whole life, she rarely sees them and cannot guess what they are thinking. Her favorite food is curry. She has a glamorous body with large breasts, but since she doesn't care about dressing up, she pays no attention to them; if anything, she finds them inconvenient when putting on clothes. Though she was initially puzzled by her sister Miho's departure, she has come to understand her over time, and they are on good terms.

Even if Maho accepts a ridiculous or absurd idea, Erika only gets flustered and cannot refuse. Her favorite foods are beef tartare and lotus root simmered with mustard.
