Kanzaki Haruna♀

A newbie detective assigned to the first division of the national police agency's special detective department. Straightforward and incredibly honest, but airheaded at times; an energetic "genki" girl. She loves red bean buns and milk. She was saved by a police officer in the past, which spurred her on to become a police officer herself. She was able to become a detective at the young age of 22 years old. While pursuing a "certain case", she encounters Kusuhara and company, and decides to join their investigation.
