Voice Actors


Jungyaku Jizai no Jutsu (順逆自在の術, Yin and Yang Switch Jutsu?)

Yami Kumo Otoshi (闇蜘蛛落とし, Dark Spider Drop?)


A ninjutsu choujin. Nicknamed Shounetsu Jigoku (焦熱地獄, Hell's Inferno). He was one of the Devil Knights who served Akuma Shogun and stole the Golden Mask of the Kinniku Tribe. When the Devil Knights retreated into Warsman's body for the Five-Story Ring battle, he fought Brocken Jr. Although he had the advantage throughout the fight, Brocken won in the end when he threw the both of them over the side of the ring. As they fell, Ninja disguised himself as Brocken so Robin Mask (in the next ring down) would save him. Robin only had time to save one Brocken so he fortunately grabbed the real one, causing Ninja to be killed when he was impaled on Junkman's spikes.

The Ninja appeared again, alive and reformed, as a member of Kinnikuman Soldier's team during the survivor series for the throne of Planet Kinniku. He died fighting Satan Cross, but was brought back to life along with the rest of Team Soldier by Kinnikuman's Face Flash.

Kinnikuman Nisei

Years later, The Ninja forms the Choujin Untouchables (超人特別機動警察隊(アンタッチャブル)?) with Ataru Kinniku (Soldier). He interrupted Mantaro's fight against Hanzou, who was captured by the Ninja after his best student, Kokumo, was killed. At the end, Hanzo kills The Ninja, who later helps Mantaro through the fight as a spirit.

His spirit reappears during the Demon Seed Arc to encourage Hanzou during his fight against Gepparland. Whether or not he is revived by the Reborn Diamond with the other fallen Seigi Choujin is unknown as he has not been seen since.
