Hana Jitsuhara fights alongside her girlfriend Senri as Team Connect, a partnership rooted in a bond since kindergarten and extending into romance. Her mature, goal-driven nature contrasts with Senri's bubbly demeanor. Together, they yearn for simple moments like holding hands without triggering the Ziggurat dimension.

Initially targeting protagonist Yukiya Araki to seize his irregular Hand Shaker abilities, they battle him within the Ziggurat. After Yukiya defeats them, they become his allies, later attending his school's music festival and supporting his efforts.

Hana possesses a distinct aversion to men, finding their perceived immaturity unappealing and reinforcing her commitment to Senri; she explicitly rejects romantic involvement with men. Their relationship includes physical affection like hugging but avoids kissing, consistent with the series' portrayal.

While Hana's individual backstory remains largely unexplored, her character development focuses on her partnership with Senri and their integration into the Hand Shakers community. Their journey concludes with the main conflict's resolution, resulting in the loss of all Hand Shakers' powers.
