Hugo Bernhardt shot her armed mother in front of her when he ran into a shanty in the Burmese jungle. The mother was aiming a gun, so he shot her before she could shoot him. Since he brought the girl to his house to live with him, she never laughed. She is great at jump rope and using chopsticks. She likes birds and even tries to take and raise one, but Dr. Tenma tells her the baby will die if she does that. (Source: Monster Wiki)
