Suigetsu Ketsueki is a shinobi hailing from the Ketsueki Clan. He is currently a freelance that, who once belonged to the Hidden Mist. Sui, is known in Kirigakure by his moniker The Blood That Never Stops Flowing (血の永流, Chi no Eiryū). Additionally, he is a member of the Seven Ninja Swordsmen of the Mist.
Suigetsu is a notable member of both the Ryūgakure ANBU, and the Ketsueki Clan. Some time as a jonin he was sent on a mission to retrieve intel on Kirigakure, which is when he had a clash with the previous user of Hiramekarei. The battle was fierce, but in the end Suigetsu's Blood Release was to much for the foe leading to his death. As a token of victory Suigetsu took the blade for himself. After that successful mission, he was recruited into the ANBU.
