She has light purple hair and reddish-purple eyes. First person: I (formal/stiff) Speech style: Assertive and authoritative (ending sentences with -da, -darou, -dana).

First person: I (polite) / I (rough/casual) Speech style: Tomboyish and energetic (ending sentences with -daze, -daro, -dazo).

Appears as an adult (EX form) rather than a girl. She constantly emits a toxic dark mist and salivates due to perpetual, extreme hunger (driven by a craving for human flesh).
