Mirai Ninja

Mirai Ninja (complete Japanese title: Keigumo Kinin Gaiden Mirai Ninja), is a beat 'em up arcade game that was released by Namco in 1988 only in Japan. It runs on Namco System 2 hardware and is based on an old Japanese movie of the same name, which was released earlier in the year and directed by Keita Ameniya. The eponymous main character was portrayed by Makoto Yokoyama and voiced over by Satoshi Itō, who also portrayed Hiu-Kaku.

Plot of the movie
A man's body and soul are stolen and used as part of a demon castle. What is left becomes Mirai Ninja. He teams up with the chi students whose cyber-earmuffs show matching red symbols. They fill their swords with ammunition, grab some neo-retro-cyber-antique guns and attack the demon robot expendable ninja squad. Each fight is won by whichever side uses more gratuitous special effects. They slay the Tron-like hover droids, who are destroyed in their shame. There is a showdown with a white-armoured man with dreadlocks, who is later reincarnated by the eclipse and a lot of multi-coloured lightning. After killing the effeminate makeup-wearing spider person, the chi school fires a giant cannon at the demon castle spider cyber robot. It blows up and Mirai Ninja escapes safely.
