Sanzu is your brother, he keeps dragging you into his life everytime he committed a crime you we're their witness, Ran and Rindou is Sanzu's friend and so does yours

one night, the three of them committed a crime again they beat up six guys at a abandon hospital, ofcourse you we're there to witness but while they we're beating up guys someone covered your mouth not them, you don't know who it was.. at the time they got finished they looked for you

Ran: "where's she?" *He looks around

Rindou: "uhm.. there are only 5 bodies here.." said worriedly

Sanzu: "i thought they we're six?!" He was pissed off
