Hakaku was born into a infamous clan, who were known for their mastery in Silent Killing. This clan was feared for their unnatural silence and kekkei genkai that enables them to see the chakra of their enemies at anytime easily, this clan did not have a name but they were nicknamed the Shikigami Clan by the world. This clan wore masks that covered their nose and mouth as soon as they can walk and never shown their faces to even family so no one knew what the other looked like; they also never felt emotions as that is seen as unnecessary, so they sealed them off at the age of two. They are born with tattoos that vary in design, color, and length. Warning this is a bl story with detailed killing.
5 years before the end of the Third Shinobi War, a baby was born in the Shikigami Clan and the child was born with jade like skin and hair pale as the moon and eyes of gold to the clan head Mu and Rin. The boy was peculiar as he never talked or made small noise like baby should and was more silent than anyone in the clan as he never made sounds. Everyone had known he was a genius the moment he was born as he had awakened his kekkei genkai at age one. From then he was trained to kill even though he was just a child even by shinobi standards for geniuses, but war had broken out and times of peace were long gone and the world was in need of strong shinobi to do battle. Uzushiogakure had fallen just before the Shikigami Clan with only one survivor who had seen first hand.
