Seven Swordsman info

The members of the Seven Ninja Swordsmen were the people who came from the Bloody Mist's graduation exams with the greatest battle skills. However, the members also had a great lust for power, which led many of them to defect and become missing-nin. Kisame Hoshigaki was the first to abandon Kiri, and joined Akatsuki. Zabuza Momochi would later do the same after a failed coup d'etat and assassination attempt on the Mizukage. Before leaving, he encountered a boy named Haku with a unique ice kekkei genkai and took the boy with him, as well as the Demon Brothers, Gōzu and Meizu. It hasn't been confirmed when Raiga Kurosuki left Kiri, but it was around the same time when he discovered a boy named Ranmaru, who ended up having a similar relationship with Raiga to that of Zabuza and Haku. Ranmaru also had a special dōjutsu which Raiga used for his own purposes, furthering their relationship to that of Haku and Zabuza's.

The Hōzuki brothers, Mangetsu and Suigetsu, both trained with the intention of joining the Seven Ninja Swordsmen together. However, their ambitions were cut short when Mangetsu died and Suigetsu was captured by Orochimaru. Suigetsu has since taken an interest in collecting all of the swords of the Seven Swordsmen for himself.

According to Suigetsu, the swords of the Seven Swordsmen are passed down from generation to generation.
