The debut of Kana Kuroda in volume 4 is a huge success!! Referred to as the Kunoichi investigator, she excels at tailing and infiltration, and can disguise herself as anything from a high school girl to a hostess at a bar, blending in wherever she goes. She's the most clever (crafty) person at the station! The new and improved team members tackle traffic accidents, exhibitionists, strange corpses, a girls' night out, and drinking at home? They'll overcome any crime scene whilst complaining!
