Muramasa

Muramasa (村正 Muramasa) is Masamune's older brother and the leader of the barbarian lands' strongest Hōjō Clan. He is particularly infamous for his cruel methods in dealing with the empire's enemies and his actions are even known by Earth Land's kingdoms. One particular event was the Battle of Ōnin, where he led his forces against the Daizen Clan. After a decisive victory, Muramasa rounded out the defeated army, and, according to others' accounts, took 8,000 prisoners. He then divided them into groups of 100, blinded 99 men in each group and left one man in each with one eye so that he could lead the others home; this was done in retaliation for the death of Takimaru, who was Muramasa's favourite general and advisor, and also to crush the Daizen Clan's morale. It did not take him long to conquer the clan afterwards, proving just much of a great leader he is, not to mention merciless.

Aside from being a leader, Muramasa is also a blacksmith capable of creating some of the finest weapons the world has ever seen. His younger brother's sword was forged by him.
