When you fight that swords man demond, dont let him hit you cuz there is no way 
that you can beat him with out the special flute that you have to get at the 
secret palace place, just block when he hits. but let him hit you a couple of 
times cuz u need to in order for the next part to happen when the girl comes. 
you have to face him twice but he just lets you go as the girl saves you both 
times. first at the secret place go in the maindoor from the ocean and then open 
the doors on the sides, and go in the one closest to the door and follow it all 
the way through u could collect all the stuff or save it for jubei to pick up 
but i thing there is a key that the girl might need in the room with the green 
acid go in there and go behind the big statue with the acid infront of it and then 
you will see a shinning key, and get that im not sure if the girl needs it i cant 
remember, but just encase. keep following through all the doors until you get to 
this door and kill the big demond blocking the wall with all the legs it has just 
kill that and there should be a white little whole behind it, that leads to a 
bridge just follow that to the end. you will have to kill some demonds on the way 
but when you get to the end of it you could save your game if you want but thats 
ur choice. go in the darkness at the end and then kill the big ork and there will 
be the flute get that and go back to jubei.
