It rocks as a Detective/crime anime and even exciting like a thriller. The main character Zhang Dabao, for once with a common Chinese last name Zhang, and last name not Ye LOL which seems to be really common in Chinese anime (looking at both Quanzhis). He follows cases as a detective, but is not a real detective, just a teen in every other regard. He is so cool, and really funny. Nice guy and also really observant, he gets shy, gets sad, gets serious, That just makes him a good main character for this type of setting, very relatable and as from perspective, it ismore interesting for it being a teen going rogue into a lot of dangerous situations.

The crime is really great horror, assault, and intense. There is no episodic cases, rather the cases become part of a long crime story. Everything that happens goes towards the course of the story. This is what makes it so compelling and impacting as a detective anime. You find a real detective story you can be attracted to. ALL REALISTIC SITUATIONS TOO. It's with this, there are development in the love relationship between Zhang and Tang (the first girl in the case Zhang helped), among the crimes, it tells a really interesting romance story too. And also those that want to seek revenge on Zhang and his partner for what they solved.
