Kabochan, also known as Princess Cinderella, is a character adaptation from the classic fairy tale integrated into the world of Anpanman. Following the Cinderella archetype, she endures hardship under her stepmother and stepsisters after her father's death, relegated to servitude within her own home. She faces consistent mistreatment and is deliberately excluded from significant events, like a royal ball intended for the prince to find a bride.

Despite her oppressive environment, Kabochan's enduring kindness and gentle nature define her. She maintains hope and optimism, focusing on her dreams as resilience against her circumstances. This inner goodness attracts the loyalty and support of animal companions, reflecting the traditional motif of helpful creatures.

Facing exclusion from the ball, she receives magical aid from a Fairy Godmother figure. This character transforms Kabochan's appearance, providing elegant attire, including the iconic glass slippers, and transportation to the event. A critical condition binds this magic: it dissolves at midnight, compelling her swift departure when the hour arrives.

At the ball, her grace and beauty capture the prince's attention, leading them to share a dance. However, adhering to the warning, she flees abruptly at midnight's stroke. In her haste, she leaves behind one glass slipper. This slipper becomes the key to her identification as the prince initiates a kingdom-wide search for the woman whose foot it fits perfectly.

The prince locates Kabochan, and the glass slipper proves a perfect match, confirming her identity as the mysterious woman from the ball. This leads to her union with the prince, elevating her to princess status and escaping her former life of servitude.
