Secret Swords

The most feared ninja brotherhood in Japan, the Secret Swords (in Japanese, the Mitsugatana) are spoken of only in whispers across the underworld. Founded during medieval times, they are masters of the arts of stealth, deception, and murder. The Mitsugatana are also masters of black ninja magic and rely as much on terror as on skill at arms.

The trademark of their most skilled agents is their demonic hannyu, or grinning masks.

After World War II, the group was led by Black Scorpion, who trained many ninjas to operate in the modern era. After his demise at the hands of Avenger, the group was taken over by one of his students, Ichiban. Now, the Mitsugatana are known worldwide as a brotherhood of assassins for hire.

Many of their current and former agents and traineers are are well-known and include Avenger, Dragon, Tarantula, Raven, and Master Zan.
