Fairy Tail: I'm Not the Most Terrifying Mage

Deceptive magic?
It's just a weak form of magic that can only deceive the five senses and the seven emotions and six desires.
Yefried always said that, but no one thought so!
-
Natsu: I used to think I was fighting with Yefrit in the forest all day, until Happy told me that he and he were fishing by the river that day!
Gray: I thought I was wearing clothes countless times until the Council warned me not to run around shirtless all year round!
Erza: I used to think Yefrit's magic was just some kind of fraudulent magic, until I got a face full of pimples and realized I had been eating chili peppers like they were cakes for a whole month!
Lucy: I truly believed Yefried was a weak person, until we fought tooth and nail to defeat the Oración Seis, only to find he was already...
Wendy: Mr. Yeffert may look kind, but he's actually quite terrifying.
Laxus: Yefrit, I don't want to fight you!
"..."
Yefrit sighed helplessly: "I'm just a weak mage who can't even create a little bit of magical effects."
