Hiroshi :" This is my father's voice , I'm not dreaming..."

Shiba :

"What you see is not me for real .

I've stored in the computer anything I knew

In the event of an accident .

During an archaeological digging I discovered an ancient bronze bell

With engravings in a language unknown.

Once deciphered I learned that it belonged to an advanced people

lived thousands of years ago in which science was not used to make life easier for all

 but for the oppression of 'man on man'.

This was the Yamatai Kingdom

governed by perfidious Queen Himika and her haniwa warriors."

Hiroshi learns about his father's death, and his legacy:

after the accident, Hiroshi was turned by his father into a cyborg,

the bronze bell hidden in his own chest,

able to transform into the head of a giant robot,

the Steel Jeeg, created by Prof. Shiba

with the purpose of stopping the Yamatai invasion of modern Japan .
