A grasshopper-like, motorcycle-riding cyborg (joined by another one later in the show) fights the evil organization that transformed him for their evil deeds.

This sequel to the Silent Mobius The Movie 1 continues the timeline of the flashback section of the first movie (Katsumis initial contact with AMP), using some more ideas and persons from the Manga, and being slightly less incompatible to the Silent Mobius series from 1998.
