Amaimon's favorite animal

I do not own blue exorcist or any of the characters.

A chuckle rang throughout the large room. Mephisto smirked deviously as his new potion was completed. He stared intently at the magenta fluid sloshing around in the vial. He took a whiff and almost immediatly gagged. The heels of his shoes clicked against the floor as he walked towards the table. After adding a few more ingredients, he poofed leaving behind a pink cloud.

He reappeared in the exorcist training room, watching as the sweaty exwires ran away from low-class demons. He spotted Rin fighting with a classmate and smirked. He spotted Rin's teal waterbottle on the bench. After unscrewing the lid, he pulled out the vial and gently poured the liquid in.

"Alright everyone, that's enough for today", Yukio shouted.

Seeing everyone coming back, Mephisto closed the bottle and poofed away.

"Ugg..I'm so thirsty..", Rin groaned.

"Oh shut up, everyone else is too", Bon snapped back at him. Rin was too tired to argue so he let it slide. He collasped onto the bench and grabbed his waterbottle. After taking a huge gulp, he felt like puking.

"What the hell?! This taste like shit", he abruptly cursed. Everyone ignored from exhaustion. A few minutes later Rin didn't feel good at all. He felt nauseous and had a major headache.

Mephisto was watching from above, grinning with amusement.

"Let the fun begin", he cheered with sadistic joy.

"Nii-san, are you okay", Yukio asked with concern.

"I'll be fine, I'm gonna try and sleep it off", Rin said slipping under the covers.

Rin's pov

I opened my eyes slowly, trying to adjust to the light coming through the windows. I looked around, noticing that everything looked a lot larger than before. Especially the bed...what the hell's going on?

My ear started itching so I moved my paw up to scratch it. Wait, paw? I look down only to see two black paws. What's happening, I think to myself. I leap off the bed, landing on four limbs. I race up to the mirror only to see a black cat in my reflection.

This is all just a bad dream right? I'm still in my bed sleeping...r-right? I thought pacing furiously. I hear the window open suddenly and something landing on the floor. I swerve around and I saw the thing I did not want to see the most. The demon earth king, Amaimon.
