On first glance, Millionaire Detective seems like Sherlock Holmes if were rich instead of smart, following the Japanese Anime Cliches. However, once you watch the first episode, you can't help but enjoy it a lot.
Based on the novel of the same name, Millionaire Detective follows the story of Haru Kato, a washed up detective who is now a part of Crimes Prevention Squad (which is just a front for doing small tasks as cops such as Crowd Control, Evacuation etc) who must deal with a new member of their squad Daisuke Kambe, a millionaire who often tries to solve cases in the most extravagant and expensive way. From the first episode alone you fall in love with the character of Daisuke Kambe from his suave persona, to cool guy personality and the fact that his loaded. You also sympathise with Haru who often has to deal with Kambe's antics and expenses (even though it is paid by him).
Halfway into the anime, the story starts to feel bland. The second half does follow a continuous story where we learn more about Daisuke Kambe, the secrets of his family and his motives behind joining the police force. However, it seemed poorly executed as I didn't enjoy it as I have enjoyed the previous episodes. Regardless, Millionaire Detective is an enjoyable anime and it is still worth a watch.
If you love Detective Mystery Thrillers, and Millionaire stories and want to see them together at the same screen, Millionaire Detective is just for you. The story, animation, characters and the opening theme song will make it worth your while. Even at the second half.
