Fio

Fio is a 23-year-old rookie detective.
He has a kind and caring personality, but his taciturn nature led to his demotion to the detective division.
He's bad at shooting and not good at paperwork either. His abilities as a detective are somewhat lacking, but he's stubbornly sticking with it.
He cherishes the jacket he inherited from his father, wearing it to give himself a detective-like appearance.
