The competition gets personal when the team is tasked with chasing a crystal smuggler. By assisting Minamoto with the interrogation of the dealer's lover, Kawai is able to witness unusual methods firsthand.

It's a horrible day for Kawai for she temporary has to team up with Shikine, an officer who is often over-enthusiastic and overly straight-laced.

After Makitaka gets the victim's statement and Minamoto and Fuji spot Yasuda leaving the house, it seems the case is finally over. However, for lack of evidence, they still have to be cautious, which basically takes Kawai and company off the rest of the case.
