The series truly has everything. Everything a good crime series shouldn't have. Over-the-top and unbelievable characters, lousy plots, and bad artwork.
It begins with the detectives. Two wealthy heirs from industrial families who pursue police work as a hobby. He with complete arrogant conviction, she practically in secret. They also have a butler for the female detective, who ends up solving the cases for them because they're supposedly too stupid. But how are they supposed to solve the cases, which were designed on the drawing board-and apparently a few 30-sided dice were also used to construct unbelievable events and twists, making everything even more unbelievable.
Furthermore, the series, which is set almost entirely in the upper class, has every kind of cliché you can imagine. And unfortunately, it shows that in Japan, people apparently can't empathize with other cultures. For example, a descendant of a Japanese mother born and raised in the USA acts exactly like a Japanese person. With not only the same moral values, but also the same cultural and everyday behavior. Even if the series were to portray the Japanese legal system even remotely adequately, that would be fatal. Because then, for reasons of shame and saving face, many capital crimes would not be prosecuted by the state because they go unreported. That would be a deeply archaic system.
The series is neither suitable as a crime thriller-it's simply not exciting-nor as a comedy-it's simply not funny. And from a German (speaking) perspective, the dubbed version produced in South Africa is unbelievably bad.
