In grade school, Kobeni had her parents buy her an ice cream just once for her birthday. She described the first taste as being so good that she broke into a run, tripped, and dropped the ice cream.
Kobeni became a Devil Hunter partially because her parents forced her into work to support her brother to be able to go to college. Faced with the choice of becoming a sex worker or a Devil Hunter, Kobeni opted to become a Devil Hunter and joined Public Safety despite wanting to go to college too.
