The Legend of Ninja Kamui - Season 1 (1969)

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.

Assassin Heima suspects Kamui is the "werewolf" terrorizing a village but is trapped, while the werewolf saves his son, Taichi.

Kamui joins the "Tozura Group" of woodcutters, protecting a mistreated girl, Tone, while uncovering a plot against him and growing closer to her.

After betrayal, Kamui becomes paranoid, killing strangers he believes are assassins as a dark force takes control of him.

Blinded in battle, Kamui is cared for by hunter Senkichi, who later betrays him for money when an assassin seeks information about Kamui.

Kamui escapes to a farming village, working as a laborer and finding peace, but his tranquil life is short-lived.

Assassin Konoma, unsure if Kamui is truly blind, challenges him but is saved by Kamui, and ultimately chooses to become a rogue ninja like him.

After surviving a fall, the "Tengu" from Tanba resumes chasing Kamui and Konoma, but the mad horse reappears.

Kamui's paranoia leads to killings by an imposter using the "Ushimino" technique, who takes his appearance, while the real Kamui remains elsewhere.

Tengu's subordinates consider becoming rogue ninjas, prompting O-Atama to use Hanzo to gain their trust.
