This series successfully developed new themes and storyline. You can really enjoy its originality and police actions. Since the opening followed what was going on in season 2 and You're Under Arrest No Mercy, it is best to watch those first, even though it is not required. In this series, there were a couples of storylines and characters' personalities slightly inconsistent from the past stories (S1, S2 & No Mercy). Nevertheless, it is quite entertained and enjoyable. The differences in Miyuki in this series made a lot more sense and served the story better in comparison to in S2. You will enjoy seeing the maincharacter's wit and strength and won't have a moment of boredom.
