Kazuki Ferrari

Age: 17 She's the middle Ferrari sister. Unlike Hazuki, she is the "cool" type who doesn't show her emotions on the surface, but she is actually quite timid and prone to worrying. Kazuki has strong physical abilities and Shorinji Kempo is her strong point. She seems to have feelings for a boy her age at her school, always looking at her phone of his picture and not wanting to throw away her phone when her sisters handed out walkie-talkies.
