The advanced I-403 Submarine was the summit
of Japan's navy capabilities during World War
II. The craft was able to exceed depths of nearly
3,000 meters, as well as contain the newest line
of guided torpedoes. Truly a sight to behold the
ship was, until one fateful day. Patrolling the
seas, protecting it's beloved land, the I-403
Submarine was attacked and captured. Fearing that
the surface dwellers' fleet would surpass their
own, the undersea Mu people seized the vessel.
But when they entered the ship, they found no
crew, no captain. Only a few scraps of papers
that promised the construction of another submarine.
Terror now caressed the people of Mu. Captain
Shinguji would soon build and show the world of
Japan's newest weapon: the undersea warship Gotengo.
