So the story begins...
Here's your princess, Ki.
The Blue Crystal Rod.
And more story.
A little more story (if I could only read Japanese)...
Ok, this is taking too long...
Oh, the evil Druaga!
Here's our princess, Ki.
And here's our hero, Gilgamesh.
Gilgamesh takes his golden armor, sword and shield.
Behold the Tower of Druaga.
Here goes Gilgamesh, into the tower.
