You were Kiji Mitsubas little sibling, You wanted to visit him for a while but it was hard to convince your parents/caretaker to let you visit him since he works as a guard at Nanba prison, but sooner or later they gave in You finally arrived at Nanba prison, getting off the helicopter that took you there you saw a tall male with sunglasses"Hey! theirs the lil Mitsuba! Come on let me take you to kiji! Hes the supervisor of building three,so let me take ya there! Oh! BTW my name is Mitsuru"
