Tantei Gakuen Q

When it comes to the mystery genre for Anime and Manga, both series are well known and could be considered classics for their own reasons. Both series feature high school detectives too. 

The main characters have super intelligent for solving crimes 

both anime are detective series.. they have many interest part and some similiar story cases.. both main character are also teenager detective.. and there are many similiar thing on these anime.. during I have watching many anime.. these are the best anime of detective series.. for you guys who like detective series.. I really recommend you to watch them.. ^^ 

Both are about detectives solving all kinds of cases. 

Same mystery genre. However, mysteries are solved by a team of gifted middle schoolers. Also, the cases here are much more realistic than Detective Conan. 

Both shows are about solving cases and having an organization as antagonists 

Detective Conan and Tantei Gakuen Q are very similar. They are both mystery, and focus on a very smart, young detective who solve cases. They both have someone who is very good at fighting. Also they both have "master of disguises". They both have organizations looking for them. While Conan is solving cases to find information about the Black Organization, Tantei Gakuen Q are working to ambush Pluto! 

Very good anime and has a lot of similarities to Detective Conan, and it is way shorter. The main characters have really good VA's from popular anime: Ryu (Neji from Naruto) and Kyu (Naoi from Angel Beats). The action in this for how many episodes there are is really nice and the plot is actually visible. If you are looking for a good detective anime, watch this. 

They both have great mysteries and both have great feels on how crime should be solved. Both have children has detectives. 

The main similarity between the two shows is the focus on teenage detectives who solve tricks behind various crimes (most commonly murders) and are very good at it. Some of the cases they encounter are related to a criminal organization that the main characters are trying to stop.  

Spiral and Tantei Gauken Q both deal with mystery sindicates that they are out to stop. There is also a rather dark mood to both shows, though Spiral is probabbly the darkest of the two. 

lot's of mysteries, although Spiral is definitely darker one, and more dangerous for participants... Still, breathtaking mysteries, and danger, and also tricks, you can find it in both, though Tantei is by far more cheerful.  

If you're keen on checking out some detective fiction, then these two series should definitely be considered. Both series features the theme of mystery and thus involves detectives. The main characters plays the role of the detectives in this case. Both series takes place at a school life setting although some of the cases involves stepping out of the field. Both series' main female protagonist has similar personalities in that they are curious but also intelligent and helpful girls who wants to be useful to the cases. Both series has drama, comedy, mystery, and action occasionally when the needs arises. 

Both are mystery orientated anime, and both involve rather big groups to help in the cases (unlike Conan or Kindachi). Though Ghost hunt is more on the supernatural and Detective School Q is mainly about closed room murders, enjoying one will lead to enjoying the other, if your heart can stand Ghost Hunt, that is. 

Crime, investigations, suspense, a group of people that stick together in "fishy" situations...Yup, these are just some of the similarities. Even though Ghost Hunt is more on SF part, they still have the detective touch as a similarity. So go ahead, watch them both, a get that detective spirit going! 

Both gives a creepy scary feeling when trying to solve a case, especially an eerie case. Both shows takes you on a journey on how the case is solved. However, ghost hunt is about solving cases due to the supernatural, and detective academy Q is total logic. 

both of them are around mysteries , they both differ at the base source , manga and an light novel and has the difference . But for an mystery fan this would be the most awesome anime of this year  

Mystery, mystery, and mystery. These two series revolves around detective fiction and with a group of friends at school. There is drama, comedy, and suspense. If you're looking for some brain twisters and plot thrillers, then these two series are something to keep an eye on. 

Come from the same author, it has the same model mystery
