To put it simply, this anime is about Japanese Batman but with a twist. I can say that we had fun and good laugh throughout the anime, especially with the sound effect. Unfortunately, owing to our high expectation on this, it didn't life to the hype. This anime contains a few genres of detective, mystery and action. (WARNING! there will be violence, blood and death which viewer discretion is advised.)
The first few episodes actually didn't really hooked us, but after they got the ball rolling, the anime began to shine. The plot and the climax was cliche but easy to follow and enjoyable.
For the characters introduction were slightly floppy and it was hard to keep track on. Also, sometimes the characters pop up out of no where and without context. Fortunately, the main characters development were pretty neat with a lot of ups and downs so it was a fun ride.
Last but no least is the animation which we disappointed the most, significantly the cgi of the cars in the first episode. Thankfully, It slightly improve in the later episodes. Additionally, the animation on characters was pretty acceptable.
In conclusion, it was a decent anime to kill your time. We gave it three starts for the overall performent of the anime.
