The deterioration of law and order. This is one of the biggest problems for the police. What the police wanted was a 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?
