Step into the underground world of assassins where we do not familiarize ourselves with the term assassins but only known as Merchants of Death. We auction lives and prices can get high but at the end of the day we cannot lie, we do make good business.

Brother Assassin is an urban fantasy shounen manga set somewhere in Japan, in present times. It revolves around the lives of two brothers who are both assassins leading normal lives by day but grim lives at night. Under the orders of Kakeru, one of the most notorious Merchants of Death, they loyally set out to kill their designated targets. But unknown to their boss, they are not normal humans. They are Dark Beings, gifted with powers unique to the clan they are tied with. They have to form alliance with as many Dark Clans as possible, especially with the Four major Dark Families of the city because if they fail to do so, then their existence is at stake.
