LINEBECK!!!! >:( [SPOILER WARNING]

[PokemonMaster]

I can't beat the Bellum controlled Linebeck.  My brother and I can't get the fairy back from bellum's arms.  The guides I used said slash at him untill it says rub and then the fairy is free, I forget fairy's name.

First off-Spoiler warning. Put it in the title, please. I've already beaten the game, but that doesn't mean everyone has.

Second off-
Just keep fighting, you'll eventually have your blades crossed, and you'll just keep rubbing until Ciela's free.

[Hi no Seijin]

Once you've clashed swords with Bellum and out rub him (hmm, that'll probably sound weird), you should be given a chance to strike him.  Once you hit him, Ciela will be able to release a Phantom Sphere.

Thanks for the advice now I can't beat without dying 3rd time. ;)
