Tsubasa Amano, a 13-year-old student at Roman Curia Surei Academy, has dark greenish-blue hair styled in braids, vivid blue eyes, and relies on a wheelchair. Initially timid and dependent on her childhood friend Miyuki Seta, she gradually reveals courage and resolve, actively supporting allies in confrontations such as battles against Wan despite her mobility challenges.

As the granddaughter of the academy’s former chairman, she inherits the High Circuit Magdalena of Thunder, channeling electricity manipulation—a pivotal ability until Hana Katsuragi transfers this power, freeing Tsubasa to embrace a mundane existence alongside Miyuki. Their bond, forged by a childhood vow for Tsubasa to become Miyuki’s wife, faces tension due to external pressures and Miyuki’s lingering guilt over protective failures.

While the manga portrays her enduring classmates’ bullying, the anime reimagines her as a revered figure. Academically inclined toward programming and literature, her online persona radiates cheerfulness and sociability, starkly contrasting her reserved real-world demeanor.

Noted for her petite physique—75 cm bust, 53 cm waist, 73 cm hips—her smaller chest compared to Miyuki’s becomes a lighthearted topic in dialogues referencing their past. Strategic prowess defines her confrontations, such as her calculated duel against Sasha, where she secures a decisive, humiliating victory.

Her narrative concludes in the anime with her shedding supernatural burdens, transitioning into an ordinary life shared peacefully with Miyuki—a symbolic emancipation from her former electrifying power.
