What I'm saying is that you guys translated the JP Wiki wrong. Again I'm pretty sure it's erasing our buffs, not the debuffs on itself. I'm talking about Demon battles. So unless you have a vid that's actually relevant to that, I don't need to watch you struggle against Lilims. :P
Does seem Expert Demons remove self de-buffs on a rage burst, though I swear it seems random as hell currently.
