With whom did father have a duel and lose?..
For what reason did he fight and die?
Even I don't know for sure.

The day after he disappeared, in father's room I found a letter addressed to me
It said "Ryu, I am on my way to a life or death duel
If it is destiny that I no return, you are to take the Dragon sword of the Hayabusa family
and go to America and see the archaeologist, Walter Smith.

Ryu, be always brave..."

I will get my revenge!
