The deterioration of law and order.... This is one of the biggest problems for the police. What the police wanted was the symbol of authority, and it was constructed with spending a lot of money and time. A huge airship called "Patvessel"! It was planned to be used for people's peace at first. But the boss of the police arbitrarily gave it to his daughter, Hikari, a big troublemaker. What will happen to the police and people...?
