after reading this manga untill chapter 33 i think i should make a review of this great manga ( well according to me).

well at first the story is little slow but if you read further you will enjoy and continue to finish it.
the story is about people who have "iris",a special power to see something that varies from person to person but our main protagonist doesn't have that special powers, but he covered his weakness with sharp thingking and high deduction.
this manga have some strong point like the plot story, the problem of every character, problem solving but the most interesting thing is how he manages to make the most ordinary person of the story the most special in his own way. That is work of some kind of genius. the character development also astonishing and display much emotions.
the art is pretty decent but is not important right? its just a bonus. if you have a free time its good to read this manga, cheers 8-).
