Reading Spiral: Bonds of Reasoning. Or Spiral: Suiri no Kizuna for you who prefer the original names. :p
A kewl manga about a person who solves a string of cases that all relate to a certain group, which has some connection to his brother's disappearance.
Also, does 1/2 Prince get any better from the first volume?
Because I really disliked the forced humour that ruined the atmosphere in exciting moments, even going as far as blasting the fourth wall to the orbit.
I did like the idea, though...
