Hizuru is a tall, striking woman with a dignified presence. She has long black hair often tied back into a ponytail, emphasizing her sharp facial features and piercing eyes that reflect her intelligence and intensity. Her attire is practical and minimalist, often consisting of dark clothing suitable for movement and combat, which contrasts with her sophisticated aura as a novelist.

When in combat or under the influence of Ryunosuke’s personality, her demeanor and posture become noticeably more aggressive, reflecting the shift in her personality. This transformation is subtle yet distinct, emphasizing the duality within her character.

Hizuru is highly intelligent, analytical, and composed, often serving as a voice of reason in chaotic situations. She is methodical in her approach to unraveling the mysteries of Hitogashima and demonstrates unwavering determination in facing the shadows that plague the island. However, Hizuru can also be reserved and emotionally distant, a reflection of the trauma she carries from the loss of her twin brother.

Ryunosuke, her alternate personality, is the opposite of Hizuru: impulsive, hot-headed, and fiercely combative. When he takes over, Hizuru’s body language and speech patterns change dramatically, showcasing his aggressive and direct nature. Despite their differences, the two personalities complement each other, enabling them to navigate the dangers of the island with precision and strength.
