- Her story: As a child, she had no desire to become a shinobi, and believed she didn't have what it takes. However, her father continued to push her to train, despite her protests. This eventually resulted in an incident where she tried to skip training, angering both her father and Imu. Out of irritation, Imu took her stuffed bear, Bebeby, and tried to rip its head off. Murasaki blacked out, and when she came to, Imu was lying at her feet, unconscious.
