Tazusa Andō, a Lily of Yurigaoka Girls' Academy and member of Team Hitotsuyanagi, carries scars from her harrowing childhood under G.E.H.E.N.A.’s experiments to forge her into a Boosted Lily. These trials bred a cold, rebellious exterior and a fractured psyche plagued by Magi Sensitivity—a condition fueling aggression and fierce independence. Her father, Andō Soitsu, once celebrated as a CHARM-wielding hero of the Antarctic Campaign, fell to infamy after the Shizuoka defense collapse, his subsequent death thrusting Tazusa into G.E.H.E.N.A.’s clutches for her rare Skiller Value. Rescued by Yurigaoka through the efforts of Takamatsu Shiera, her father’s former comrade, she now remains under the academy’s vigilant guard.

Behind her guarded demeanor lies vulnerability. Trust, once given, ignites unshakable loyalty, exemplified by her Schutzengel’s Oath with teammate Yoshimura Thi Mai. Though clumsy with emotional expression, Tazusa confronts conflicts head-on, mediating clashes like the Kyushu mission rift between Shenlin Kuo and Yujia Wang. Her combat mirrors her father’s legacy: a speed-type Phantasm fighter, weaving predictive strikes and regenerative gambits to dominate battles through calculated recklessness.

Conflicting records note her Tokyo birthplace, her mother’s suicide post-Soitsu’s demise, and a politically orchestrated rescue. Past friendships with Kuo Shenlin and Takahata Masaki frayed after Masaki’s transfer, leaving echoes of loss.

Privately, Tazusa finds solace in origami, adores Munchkin and Kinkalow cats, and avoids confined spaces. A voracious appetite and coffee preference contrast her lean frame. Her name—symbolizing cranes, gossamer, peace, and wisteria—hints at ties to architect Andō Tadao.

Over time, bonds with Thi Mai and efforts to mend team fractures chart her fragile evolution from solitude to tentative kinship, a testament to resilience etched in scars and slow-blooming trust.
