Kokoro's mother emerges as a hardworking and caring figure, serving as the sole actively involved parent in Kokoro's life. When severe bullying causes Kokoro to stop attending school, her mother reacts with concern and quiet frustration, striving to understand her daughter while encouraging her return to education. She takes concrete action by arranging Kokoro's transfer to a child development support class, an initial source of discomfort for Kokoro. Throughout this withdrawal, her mother upholds household stability, balancing work responsibilities with providing a secure home environment for Kokoro's retreat.

Demonstrating attentiveness, she notices Kokoro's distress during school-related discussions. As Kokoro confides about being bullied by Miori Sanada, her mother listens seriously and collaborates with school teachers to address the situation, shifting from initial uncertainty to active problem-solving. Her support extends beyond practical steps to emotional backing, helping Kokoro process her experiences and rebuild confidence.

During Kokoro's period of hiding at home, her mother respects the need for space while remaining available. She continues daily routines like leaving for work, inadvertently creating opportunities for Kokoro to visit the magical castle during school hours. This consistent presence forms the foundation for Kokoro's eventual steps toward recovery and return to school.
