Koshonin Stuff

( In a certain prison interrogation room )

EDIT: Character Synopsis.
"Five years prior, Mariya Kyousuke was arrested for a string of murders (serial murders). At that time, it was Usagi Reiko who was working for the juvenile division that arrested him. From then on, once a week, she visits him. It was Reiko herself that imposes these visits.
[When Reiko told the dying Mariya that she would no longer visit him. Mariya repented for the crimes and cried while pleading for his life, until Reiko said she wouldn't let him die.]
There appears to be a strange bond between these two."

I'm not sure about the bit in brackets.
