When you first start, press A or Z to dodge the first three attacks. When she pulls her hand (left or right) to attack, wait until you see the Wiimote appear on screen to attack. Dodge what she fires at you and attack her like before. Then press B to use Soul Surge. Keep swinging the Wiimote. Repeat this until she has been defeated. When she turns black she is almost dead. Be careful; she may try to stab you. Defeat her in less than 2:30 minutes to get a lot of followers.
