Kumagami is Ota's backup. She's Kanuka's replacement after she returns to New York. She was top of her class, and is an exceptional police officer. She was courted by several police agencies, but eventually chose the SV2 because of the challenge. Kumagami seems to be very level headed and nothing seems to faze her, though the antics of her workmates sometimes annoys her. Kumagami has an irrational fear of the supernatural, especially ghosts as her father was interested in the topic and she heard many ghost stories when she was a child.
