If it's just bluster like the stuff about his plot of land sure... but here he really was not affected by magic barrier particles. That stuff brougth even Laxus down... or at least strongly affected him... but Gajeel isn't affected in the slightest. And that is what is bothering me.

Gajeel can talk trash for all the chapter as long as it's just talk, but in this case Hiro cheaply swindled out of giving a sensible explanation for why the MBP don't work on Gajeel, when by all rights they should - or rather have to - affect him. Unless there are other types of MBP than the one Torafusa released that work fundamentally different, I don't see any way to avoid being affected as long as your still breathing, except for protective masks like the guys with the gas masks in Hargeon or Levy's Mask Spell. In the past I would likely have complained about a spell countering magic destroying particles... but after the Wahl desaster... whatever... but Iron Lungs? That's just so stupid.
