When Kurt Zisa moves his blades around him in a spiral form run away from him. Then when he's done go back and attack those darkness balls (you might want to equip a strong weapon and have ready a lot of HI-Potions and Ethers). When he stars spinning his entire body in a horizontal way and comes close to you jump (you should equip the ability High Jump for this method). When Kurt Zisa spins his body in a vertical way you sould run to the left and then push the square button to do the Dodge Roll (time this just right or you'll get seriously hurt). After you know what to do it should be easy if you're good at this game. Last thing: You should attack him quickly because at some point Kurt Zisa will recover more quickly. GOOD LUCK GUYS!
