Hmm...I didn't have a problem with Volt, so I'm not sure what to tell you. Have Raine in your party for healing. I used Kratos, Lloyd, and Collette, though Genis is probably a better choice. Set one of your C-Stick commands to Raine's First Aid, or Nurse if she has it by then, and use it when you need it, and Raine SHOULD listen to you. Hope that helps a little bit.
Beat the game while I was away on vacation...
Now I have my restart game, and I saved my old game to file 2, so I can do more sidequests, get all the best weapons, get more Grade, ect.
It was funny watching the last ending scene with Pirate Lloyd, Beach Collette, Judgement Kratos, Katz Genis, Maiden Raine, Klonoa Presea,Chef Regal, and Swimwear Sheena. XD
Next time I'll actually have em have their normal outfits. ^^;
