S3·E6 Aoi-chan becomes a man?!

A police officer comes out of retirement to help out with things in Bokuto Station. Apparently the officer knows Aoi from some previous officer work, and since Aoi is still cross-dressing as a woman, the officer tries to turn Aoi into a man by giving him and the entire department some special training. Aoi doesn’t want to change his ways, but he and Natsumi stick with the training.
