Review Detail of Blast_Niro in i am just a student? in Conan world

what the hell type of premise is this, this is the world of Conan where everyone week a murder happens and a mystery is revealed, where secret organizations plot in the shadows and phantom thieves pop every Sunday. but no the mc's biggest problem is taxes even though he's a student and a detective to but which leads me to believe he's shit at said profession if he needed a system for help, all in all trash premise.
