Rumia Tingel, born Ermiana El Kel Alzano on July 7, 1837, served as the Alzano Empire’s second princess until her early exile. Labeled a “supernatural” and deemed unfit for royalty by her mother, Queen Alicia VII, she faced banishment, kidnapping, and eventual rescue by assassin Glenn Radars, acting under the queen’s orders. Adopted by the Fibel family and renamed Rumia Tingel, she grew as foster sister to Sistine Fibel, their bond evolving from initial friction to profound closeness. Rumia assumed a nurturing role, mediating conflicts involving Sistine while balancing gentleness with steely resolve—evident when she defiantly held her ground during a high-stakes magic competition.

Her appearance—shoulder-length blonde hair, aquamarine eyes, a signature green bow, and blue hair clips—paired with her school uniform and statuesque frame, occasionally sparked playful rivalry with Sistine. Beneath her composed demeanor lay scars of trauma: a staged death rumor erased her royal identity, and a public confrontation with Queen Alicia, triggered by the absence of a treasured family locket, crystallized her abandonment.

Rumia’s relationship with Glenn shifted from reliance on his protection to admiration for his selfless dedication. She navigated quiet jealousy toward women like Sistine, Celica, and Eve, perceiving them as rivals for his affection, yet maintained unwavering support for her foster sister during crises. Her aspirations extended beyond personal ties, driven by a vision to guide humanity’s ethical use of magic.

Key moments, such as her strategic brilliance during the Magic Competition and a hostage ordeal that tested her resilience, charted her transformation from sheltered exile to a leader confronting emotional and societal complexities. Each trial underscored her duality: vulnerability masked by fortitude, and compassion tempered by unyielding determination.
