Masaki Iizumi

Okatsu is a widow raising five children - adults but still mama-dependent - in mid-eighteenth century Edo, Japan. Her frugality attracts unflattering comment even amid national tough times (the region is in famine) What Okatsu tells no one is that she saves so that a friend can start his own business once he's released from prison.

Commander Sugata discovered the existence of the Royal Underground Empire Tube, a malignant force that desires to dominate the land, which is based underneath Japan. He recruits five young people, each one specializing in a style of martial arts, and teaches them in the ways of the mystical "Aura Power" energy. A year after he recruited and trained the Maskmen, Tube is ready to strike.
