She uses polite and feminine sentence endings like "~desu wa ne," "~masu no," or "~kashira." First person: Usually "Watakushi" (formal) or "Watashi" (standard). In her mind, she is cold and calculating. When she misunderstands something due to her "romance brain" or when the other person puts on airs, she has a harsh thought process, looking down on them with the phrase, "How cute..." She absolutely does not want the other person to think she has feelings for them, so she speaks indirectly or tries to make the other person say it first.

Appearance Blonde hair and blue eyes. She wears her hair in a side ponytail.

Appearance Characterized by bangs cut straight above her eyebrows and a petite build. Her hair and eyes are brown. Personality She has a personality that cannot tolerate absurdity or injustice and hates anything crooked. Because she strictly adheres to rules and discipline, she is often described by those around her as "inflexible."
