Suigetsu was born in Kirigakure. Reputed to be the "Reincarnation of the Kijin", Suigetsu, together with his brother, Mangetsu, dreamt to inherit the title of Seven Ninja Swordsmen of the Mist. This acted as their motivation to finish cruel missions day by day. However, this dream was later shattered with the premature death of his brother, and Suigetsu changed his ambition to "collecting all of the swords". With the humiliation of being captured by Orochimaru, his ambition was put on hold.
