Description
Setsuna Yūki, whose real name is Nana Nakagawa, attends Nijigasaki High School as a second-year student. She crafts a dual identity, borrowing the stage name Setsuna Yūki from light novel characters to hide her idol endeavors from her strict family, which forbids interests like anime, manga, and school idols. As Nana Nakagawa, she fulfills student council president duties while wearing glasses and braided pigtails—a deliberate contrast to Setsuna’s flowing hair, partial ponytail, and rose ornament. This separation sparks campus urban legends about her elusive presence.

Energetic, charismatic, and emotionally expressive, Setsuna radiates intense passion for school idols, anime, manga, and video games, often diving into lengthy discussions about them. Initially, she suppresses these interests due to family rules and her presidential role. She demonstrates fierce loyalty to friends, enduring Kasumi Nakasu’s spicy bread to avoid causing disappointment. Her cooking earns the label "too original," though peers tactfully avoid remarking on its flavor.

Within Nijiyon Animation 2, Setsuna features in varied episodic moments. A fantasy sequence casts her as an "overly passionate teacher" during a club storyline involving demon lord opposition. She shares an umbrella with Ayumu Uehara in the rain, visibly elated when hearing Yu Takasaki’s praise for her performances. In another scene, she dances to charm the cat Hanpen, amusing Karin Asaka. Her role in the "Victory Road" narrative highlights collaborative efforts with other members to conquer challenges, underscoring her dedication to group endeavors.

Her past reveals she established Nijigasaki’s original idol club but disbanded it after creative disagreements arose. She rejoins when the club reforms, performing as a solo idol within the collective. Her motivation springs from witnessing school idols and sensing "fate" compelling her, fueled by a dream to forge a world where passions are expressed without shame.

Across her journey, she reconciles her dual identities once her mother accepts her idol activities. She shifts from leading the initial club to embracing teamwork in the reformed group, prioritizing mutual growth and friendly rivalry.
