Division 2 return to the Police Academy to hone their fighting skills. Noa is getting a little depressed at the fact Ota is much better than her, and she is not getting much credit for her work. One night she sets off to get dinner for everyone, and sees a few ¥10,000 notes floating down a stream. She sees this as a big chance to prove herself and follows the trail of money upstream. Noa does not return to the Training Grounds, and the team are worried. They come across a local policeman who tells them a robbery has taken place. This behaviour is quite unlike her and Division 2 are now quite worried and begin to search for her.
