Mrs. Naito, Suzu’s mother, shaped her daughter’s early years with nurturing warmth and steadfast dedication to family. She prioritized moments with loved ones, fostering a deep bond with Suzu and igniting the child’s musical passion by encouraging her to compose and sing from infancy. Her tall stature, brown hair, and brown eyes were often complemented by a beige shirt adorned with white stripes.

Tragedy struck during a violent storm when Suzu was six. Witnessing a child swept into a flooding river, Mrs. Naito plunged into the torrent to rescue them but was overwhelmed by the currents. Her selfless act left Suzu burdened by unresolved grief and resentment, struggling to accept her mother’s choice to sacrifice herself for a stranger.

Before her death, Mrs. Naito anchored herself in a local choir, rehearsing with them diligently. In her absence, the choir members vowed to support Suzu, preserving a photograph of Mrs. Naito mid-performance as a tribute. Her legacy lingered in Suzu’s stifled voice—an inability to sing, born from trauma intertwined with loss.
