Yet another Sherlock Holmes rip off that autistic detective with a gimmick and his/her relatively normal (in the context) sidekick go around and solve mysteries.
I dont want to go in too much detail as it seems like there is one of these animes every season and all of them use same formula. Autistic detective with a gimmick meets the sidekick, he/she helps the sidekick to solve the problem then they team up and contunie solving more cases while detective's `oh so mysterious and tragic` past catches up with them... Basically there is nothing original to delve into. If you watch one of these, you will know exactly what to expect.
If you are a fan of the genre, you can watch it i guess. If not, dont bother. Like i mentioned above, there is one of these every season. You wouldnt miss anything.
