Jared: so the girl is confused?
Gajeel: yes now explain what they are.
Jared: so anti magic particles or also know as Magical Barrier Particles, or as known as Anti-Ethernano, can take the form of a black mist that quickly spreads in its environment. They feed on the Ethernano in the atmosphere and contaminate it, causing anyone that breathes it in to become poisoned, as well as have their Magic weakened. Said poison is lethal, especially to mages.
Gajeel: mhm
Jared: that's what it looks like. And that's what I can use.
Gajeel: so you wanna fight him now? Akane_Fernandes and you can only use that because of your curse magic!
Jared: what would you do if I used it on levy?
Gajeel: kill you.
