@FTF, well, you said exactly what the best answer should be about the whole Gajeel and MBP case, his Iron Lungs acts like a filter to air out the bad gases and such, because you wouldn't use organic substances to filter out stuff because that doesn't work at all, besides out of all the DS, he see,s like the only one who can turn into his respective element for defenses.

@Sane, well you must remember, Kagura would have no chance what so ever against Dimaria with her God Soul powers, it is like she was marching off to her own death, with Chelia, she was the only best chance to defeating her.
