Both sides of the conflict put aside their differences in order to deal with this new threat, and in the middle of the fray is a teenager named Taishi. Entrusted by his father to care for a black brief case, he finds himself the protector of the controls of a massive, mechanized robot weapon which everyone, allies and enemies alike, want to get their hands on.
