Description
Tsukasa Gojouin, a young girl from an affluent family, attends the same private school as Yuuri and lives on a sizable estate. She possesses cyan-green hair and brown eyes. Friendly and kind, especially concerned for Yuuri after his parents' loss, she appears shy and quiet at school yet becomes expressive and playful at home.

Tsukasa harbors a strong fascination with shoujo manga romance narratives, frequently projecting these fantasies onto real relationships. She enthusiastically supports the potential romance between Yuuri and his maid Lilith, finding the idea so exciting it causes nosebleeds. She demonstrates keen intuition about romantic developments, accurately predicting Yuuri and Lilith's mutual attraction early.

Her relationship with her butler Fujisaki, who serves in a maid role but avoids dresses, is central. Tsukasa imposes demanding, whimsical requests on Fujisaki, like cosplay, often using manipulative tactics such as feigned tears for compliance. Fujisaki usually sees through these ploys and openly expresses annoyance. Despite this, Tsukasa expresses gratitude for Fujisaki's patience while continuing to make unreasonable demands. They share a long-standing bond originating in childhood when they met in a park—Fujisaki skipping class and Tsukasa leaving home due to boredom from lessons.

Tsukasa actively involves herself in Yuuri's emotional life. Observing Yuuri and Lilith's interactions convinces her of their "forbidden romance," fueling her curiosity and leading her to discreetly monitor them. She eventually confronts Yuuri about his constant thoughts of Lilith, interpreting his descriptions of suspicion and physical reactions as love, causing another nosebleed from excitement. She then takes direct action, inviting Yuuri to her home and using romance story examples to help him understand and acknowledge his affection for Lilith.

Similar to Yuuri, her parents are absent from school events. Tsukasa develops from a quiet observer to a confident intervener, particularly in facilitating emotional clarity for others, while maintaining her characteristic romantic idealism and occasional childish manipulations within her established relationships.
