I don't usually do reviews but seeing as the only other review is rather negative and a bit ignorant I'll say this:

The story is interesting, like pokemon go but with real people. Some people like to say the mc is dumb but after learning his backstory his actions make more sense... I'll admit the story is a bit predictable at times but I found it over all engaging.

The art and character design is very good in my opinion and the overall world is very believable, If you don't like gore or dark stories this definitely is not the manga for you.
