Personal Life

Momoko has a big family of a mother, father, two brothers and both grandparents. She is the middle child. She liked her father, but couldn't take her mother seriously. She would often lie and sometimes steal from her family.

As a child, Momoko felt she was too mature for her age. She disliked being around children her age and found adults to be too patronizing, which eventually led to her skipping kindergarten. While at school, Momoko was bullied by an on/off friend for about a year. In high school, she had a very close friend and the two were often mistaken as being in a gay relationship.
