Zeno

The daughter of King Marden and a princess. She appears from volume 3 and later becomes the Marquess of Marden in the Natra territory. Due to her intelligence, she admonished her father's tyrannical rule, which led to her being disliked and imprisoned in a detached palace. During the fall of the capital by Cabalinu, she was the only royal family member to survive because she was in the detached palace. Subsequently, she pretended to be Helmut and became the leader of the liberation army, fighting against Cabalinu.

When Wein traveled to Cabalinu, she protected them when they were attacked by a mysterious force and later accompanied them as Zeno, the nephew of Jeeva. During this period, she was impressed by Wein's character and depth of wisdom. As a result, she received help in avenging her enemy Holonuye and achieving her long-cherished goal of liberating Marden with Natra's support. However, she desired subjugation to Natra over independence, effectively selling the country, which Wein had longed for.

In Natra, she was granted the title of Marquess and focused on managing her territory while maintaining Marden's autonomy. She is fond of Wein and is well aware of his abnormality, striving day and night in governance and studies to become his equal.
