you know how you can assign 3 characters to attack your opponents? If you have them, use kensei(silver haired vizard), Ichigo, and Orihime. Kensei and Ichigo are quick and do a fair bit of damage, while Orihime can heal up to half of your hp. Careful when using her though, as you have to remain close.
