Hozuki Ferrari

Age: 13

She's the youngest Ferrari sister.

Hozuki is a junior high school student, and she is known for being somewhat flighty. Even if she tries something, she doesn't keep at it for very long, but science is her only strong point. She is reserved and quiet, but she is probably the most likely to take action amongst the three Ferrari sisters.
