You're Under Arrest! Season 3 Episode 18
Episode Title Beachside Run
The Bokuto girls (including Aoi) go on a beach trip for their day off. They also meet up with Saori who is stationed in the North side. Nakajima tries to visit the beach to work on his relationship with Miyuki, or at least see her in a swimsuit, but he gets stuck in traffic. After some volleyball and fun in the water, the girls learn from a beach vendor that some peeping tom has been taking pictures and posting them on the Internet, so the girls help Saori scout for culprits, and set up Miyuki, Natsumi, and even Aoi-chan as bait.
