Kokindaichi Kotaro just recently got accepted to work at the Hanasaki Detective Agency and can’t wait to get real work experience as a Private Investigator.

They spend a majority of their times doing nothing and fooling around with no real case to work on.

Black Detective

Black Detective

The detectives are supposed to be the good guys, right...? That's certainly what Arata Toiro used to think, but after having his first brush with a real-life detective, suddenly he's not so sure. I mean, there's no question that even though he's still just a teenager, Yoh Kuroba is a gifted sleuth. It's just that he seems to have a peculiar predilection for making his adversaries writhe more than just catching them... That's really not normal, is it? Either way, now that he's found himself bullied into a position of playing Watson to Kuroba's Holmes, it seems that Toiro will have plenty of opportunities to find out!
