Description
Anna Schneider, older sister to Cosette and younger sister to Charlotte, belongs to a prominent family. She shares a deep childhood bond with Takt Asahina, their families long connected. After Takt's father, Kenji Asahina, dies, Anna and Cosette move in to support him, with Anna managing practical duties: cooking, housework, and vehicle maintenance.

When Cosette suffers mortal wounds shielding Takt from a D2 attack, she transforms into the Musicart Destiny, losing her original self. Anna launches a cross-country journey with Takt and Destiny towards New York Symphonica, seeking Cosette's restoration. On this trek, Anna serves as the group's logistical anchor, driving, repairing their vehicle, and managing resources. She initially struggles with Destiny's presence, calling her "Cosette" while grieving her sister's loss. Gradually, Anna accepts Destiny as a distinct entity, tearfully requesting she be called "Unmei" (Destiny).

After Destiny sacrifices her form to save Takt in the final battle, Anna inherits her power through a Transformation Trinket (F-hole). She cuts her long hair short, joins Symphonica as a Conductor, and chooses to harbor Destiny within herself. This fusion lets Anna keep her core personality and memories while gaining Destiny's combat abilities. Her choice stems from a resolve to protect the future Takt and Destiny envisioned—a world where music flourishes free from D2s.

In later events (depicted years post-anime in a mobile game), Anna fully embodies the Musicart Destiny. She spends decades safeguarding humanity from D2s, awaiting Takt's return from suspended animation even as her human memories fade. This Destiny displays a calm, elegant demeanor with occasional quirks, distinct from Anna's original personality. The manga spin-off "Haruka Reminiscence of Anna" explores her perspective during the original journey.

Her abilities encompass mastery of household and mechanical tasks, later augmented by Musicart powers: enhanced speed, swordsmanship, and regenerative combat techniques like "Thorny Path." Her ultimate ability, "Judgment Gate," enables counterattacks after taking damage. As Destiny, she wields passive abilities like "Victorious Will," boosting allies' combat effectiveness.

Anna's arc transforms grief into purpose, evolving her from a supportive figure into a protector carrying her sister's legacy and Takt's ideals. Her relationships emphasize fierce loyalty to family and commitment to preserving hope through decisive action.
