Kid of Phoenix House

Law chuckles and disappears as realization that you were now in Kids body sets in. "He can do this!?" You gasp.
"He majors in bio magic, come on, we need to make him change us back!" Kid says from your body running down the hall. You blink and rush after him, staggering slightly.
"Man you're big..." You mutter magic inside your current body feeling rugged and untamed. Law appears up ahead and Kid casts a fire spell at him. You pale slightly as the blast scorches the floor and walls.
You grab your collar turning Kid to face you. "What the hell!? Don't just use spells in my body! You might kill someone!" You snap. He blinks uneasily at you.
"Who are you?" He murmurs.
"That was alarming." Law's voice makes you both look up to see him standing on the ceiling, holding his hat to his head peering down at the peer. "Good luck explaining this to the White Beast."
"Huh...?" You murmur as he smirks and disappears.
"What the hell is going on?" A familiar silver haired man rumbles coming out of a room.
"Run." Kid breathes grabbing your hand and running down the hall. You stagger but run along beside him. You peer back to see the man change into a giant silver wolf and give chase. A surprised cry leaves you and you pick up Kid bursting away with him.
"Oi! Put me down!" He gasps.
"No! I have bad legs I can't run far or my knees will hurt." You reply looking around sensing the wolf right behind you.
"There!" He points to a door and you swiftly dive in closing the door behind you. You lean back against the door listening to the wolf's claws click against the marble as it passes. You set Kid down and look around the classroom.
"What now?" You ask.
"Mr Trafalgar!" He calls, you blink at that.
"Mr-"
"Yes? What may I do for you students?" A handsome older man inquires appearing between you two. Just one look and it was obvious he was Law's father.
"Your son switched our bodies!" Kid tells him ill tempered.
"Oh dear not again..." Mr Trafalgar sighs.
"This happens often?" You ask. He blinks and looks between you and Kid.
"Yes but he doesn't often do it to new students... My apologies." He snaps his fingers switching you both back. You relax as does Kid.
"No offense but I'm kicking your son's ass." Kid grunts.
"No offense but I second that." You agree.
"Oh dear... Then I suppose you'll have to have him change you back." He smiles snapping his fingers again and switching your bodies back.
"What!?" You both snap. He just chuckles and disappears.
"Dammit! Come on!" Kid growls going past.
"Where we going?" You ask quickly following.
"We're going to the Griffon corridor and trashing the place!" He rumbles. You sigh rubbing your cheek.
"Why does my first day have to be so chaotic..." You mutter.
