Summery: You wanna get rid of someone? Nicolas and Worick your two neighborly gangsters also known as “Benriya” are for hire!

My Opinion: Its not a serious type of Seinen. A bit of shounen flavor, minus the childish exaggerations. The characters are interesting,even if they are not very 'deep' yet. The setting is in a city ruled by three mafia families. Throw in a group called Twilights, our heroes Benrya,a rescued prostitute and a mentor of a police detective...it certainly makes for quite an interesting setting.

Also the artwork is cool.
