Saving in the mansion
You can save the game at the cat in the mansion you enter on your way to the Castle Town. To get to the cat, leave the initial room, go down the hallway from the group of demons, then go left until you see a room. Enter the room, then go to the door to the left.

Defeating Kanna
When you begin the battle with Kanna, you have to listen to what she says it helps you out in battle. When she says "you can have it" don’t attack her, all of your attacks will be reflected back to you and do damage. During this time build up your defense and attack. When she says "I want your soul" you can attack her then, if done correctly you should beat her with no flaws.
