A manga by Mitsuteru Yokoyama which ran in Weekly Shonen Sunday from 1966 to 1967, turned into a tokusatsu and then an anime in 1987, Kamen no Ninja Akakage is the tale of three ninjas during the Warring States period of Japan. They protect Japan from various warlords and their kaiju. No, they don't use giant robots or anything, they use much more inventive methods than that!
The three ninja:
- Akakage — Master Swordsman, The Hero, Master of Disguise
- Aokage — Just a Kid, Child Soldier
- Shirokage — The Lancer
Kamen no Ninja Akakage provides examples of the following tropes:
- Anachronism Stew: On purpose; the ninjas fight the monsters using anachronistic technology such as gliders and concealed guns.
- Macross Missile Massacre: Bomb/missile spamming is frequently used against the kaiju.
