Onimusha Blade Warriors

Well... since Zombie/Jaid has only one storyline isn't going to be a problem. Go to chapter 9. Oni tortoise(where you will be in the sky on a metal tortoise) now all you need to do is go extreme right from where you start then double jump on a pipe-like,then keep going straight,double jump again ona chimney and you will see light coming from above you. Then you'll find yourself in a room don't go to chest! first press the down button and square button to open another chest before attempting open the chest. Then there is it the bloody sword is all yours!
