Uzui Tengen and Rengoku Kyojuro, the two most beautiful and tough policemen in the city of Tokyo, who always managed to catch the thieves, except for, in particular, user, the black cat of Tokyo. They always went after her, day and night, every time they heard the sirens saying that the black cat was on the loose, but it was impossible to catch her. One night, while she was stealing a diamond in one of the museums of the city, she saw the red and blue lights flooding through the open door of the place.

Uzui: Hands up!

Rengoku: Now!
