No. No no no. Gajeel can sense Magic Power. Literally. Everyone in the series can. Gajeel can sense that he has it and that it is weak. Also, you are using mangastream's jaded translations to try and disprove me? Seriously? Would you like to see the actual text? Well, whether you want to or not, I'm writing it.

Gajeel: どれだけすごんでみせてもオマエは大した魔力じゃねえ (Dore dake sugonde misete mo omae wa taishita maryoku janē)　他の１２の方が迫力あるぜ (Hoka no tuerubu no hōga hakuryoku aruze) Bloodman: 我が操るは"呪力"ぞ (Ware ga ayatsuru wa "juryoku" zo)

Translation (this is my own) Gajeel: You talk pretty big for someone who's Magic Power is so pathetic! The rest of the 12 have far more than you! Bloodman: That's because what I use is called "Curse Power."

Right here. Right here Bloodman admits that his Magic Power is low because he uses Curse Power. However, Ice Devil Slayer Magic is Magic. Therefore, it operates off of Magic Power. There is no evidence in the story that says that Etherious cannot use Magic and Magic Power. However, nowhere in the story does it say that non-Etherious can use Curse Power. Therefore, Ice Devil Slayer Magic is not a curse, but a magic, like it says so in the goshdarn name.
