Kamen no Ninja: Akakage, or "Masked Ninja: Akakage", is a Famicom-exclusive video game based on the 1987 anime series of the same name (which itself is a remake of the 1967 Akakage tokusatsu). While the game mainly features the Red Shadow, Akakage, you can also freely switch to Aokage (a young boy) and Shirokage (an old man).
This run by mtvf1 mostly uses Akakage for his superior arsenal of weapons, but switches to Aokage at a few points when the young ninja can move faster.
There is some commentary by the author in the emulator movie file and in the primary (HQ) encode.
