The Legend of Ninja Kamui

Kamui, a rogue ninja, is saved by siblings Nene and Ryuta but is soon pursued by assassins seeking revenge.

Kamui escapes into the forest, where he uses a secret technique to battle the tree-fighting Masira clan.

Ryuta follows Kamui, but after Tsukikage attacks, Kamui warns him of a ninja's perilous life and tries to send him back to his sister.

Kamui battles ninja siblings Sanae and Shirou, and after defeating Shirou, he faces Sanae's revenge with her secret technique, "Iizuna Gaeshi."

Kamui hears of the undefeated ninja Mitsu of Nabari, who breaks Kamui's Kiri Slash, prompting him to seek the secret behind Mitsu's invincibility.

Kamui faces an assassin with the mind-reading technique "Tashin Tsū," forcing him to use a life-risking strategy to escape.
