This is supposed to be the main character from Musashi #9, a very serious manga series. And of course the main character is agent number 9 of the secret orginazation called 'Ultimate Blue' or 'The Other United Nations'.
I really liked the series, it's got a lot of drama, action (and a little romance.)
So if you like any of those, you'll love this series.
P.S. The person in the picture is a girl, not a boy.
