If Fairy Tail was in the modern world and the characters were regular teenagers.
Gray: Natsu why are we up in a tree?
Natsu: Because Juvia and Lucy are having a sleepover and you know what that means…(Pulls out binoculars)
Gray: You mean you dragged me all the way up here in the middle of the night, just so we could spy on them like a couple of peeping Toms? That’s so creepy!
Natsu: No it’s natural curiosity. Besides, don’t act like you wouldn’t just love to see Juvia without a bra.
Gray: (Blushes and then punches him) Dude!
Natsu: Relax! I’m only going to be staring at Lucy. I know Juvia’s your girl and I respect the dude code.
Gray: First or all, she’s not my girl. And second, you know we could go to jail for this, if we’re caught right?
Natsu: Oh stop being such a geek. (Looks at the window to the girls’s bedroom) Oh hey! I think Lucy’s about to take her shirt off!
He eagerly looks through the binoculars. Gray rolls his eyes in disapproval.
Gray: You’re really sick, you know that.
Natsu: Aww crap! I can’t see her! Some half-shaved bear is blocking my view.
Gray: (Confused) A half-shaved bear?
Natsu: Yeah, and man is he ugly, and he looks mean to. Oh, I think he’s spotted us, and he looks really mad. What’s his problem?
Gray: Let me see that. (Looks through the binoculars and suddenly gets scared) Oh shit! That’s not a bear you idiot! That’s Juvia’s brother Gajeel, and he’s coming this way!
Natsu: Ahh! Abort! Abort mission!
Both boys jump from the tree. Gray lands on his feet and runs, but Natsu lands on his face. Gray tries to help him up.
Natsu: It’s too late for me! Save yourself!
Gray runs off and the looming shadow of Gajeel falls on to Natsu.
Natsu: (Nervous) Um…Would it effect your decision to hurt me, if I told you that your sister wasn’t the one I was spying on?
