Odd Sleeping Habits (Pjo crossovers)

Welp, this isn't good...

Nagisa P.O.V.

Scribbling furiously on my homework after school, I only lifted my head as footsteps pounding got louder and louder until the door to the classroom is thrown open and in the doorway stands a breathless, raven haired boy.

 "Percy?" I ask looking at him in confusion. He had said he was going to take a nap. It had only been 10 minutes and I doubt a 10 minute nap was what he meant. His dropped head from running jerks up only seconds after I say his name his eyes locking into mine fiercely.

 "Everything is in danger. Existence itself is in danger. And I was chosen..." He croaks out collapsing unconscious into the wooden floor. Alarmed I rush out of my seat alongside several others who make a beeline to Percy.

 "Percy?" I call as I sit beside him. Suddenly Karma pushes the lot of us outta the way.

 "Get out of the way and let me check his breathing!" He commands. Upon hearing this we promptly scatter. Kneeling at his side, Karma presses his fingers to the side of Percy's neck then waits. A few seconds later Karma looks up relaxing considerably.

 "He's okay. Just unconsious." Karma declares as everyone sighs in relief.

 "Did anyone hear what he said?" Manami asked., "Something about danger and him being... er... 'chosen'. Anyone else?".

"We should go get the teachers!" Rio points out, blonde hair swishing behind her as she walks to the door and opens it, "Who's coming?" 

 "This seems like something important so we should get all three of our teachers. So say... Nagisa and Karma stay here with Percy and the rest of us will go get the teachers. Sound good?" Tomohito asks. Everyone nods in agreement and one by the one the rest of the class there at that moment files out. Practically the second the others leave Percy's eyes burst open and he jerks up violently, panting like he'd run a marathon.

 "Hades... this REALLY isn't good..." Percy mutters , eyes darting around the room.

 "What isn't good?" I ask. I wanted to know what was freaking Percy out so much.

 "I kinda... accidentally chose you guys. So now you're part of this mess as well..." He explains and groans as he collapses back into the floor muttering, "Don't have the strength of will to do this right now..." 

 "Chose?" Karma asked, "And who's we?"

 "You and Nagisa... maybe Ritsu too?" Percy mutters, "And it's starting... try not to panic... too much." Then Percy conks out. His breath light and even and obviously asleep.

 "Why would we be- ohmy*bleep*what is that?" Karma begins before stopping nod sentence when a multicolored swirling vortex of colors appear over Percy and slowly sucks him into it. The pull is tugging at me and Karma too by the looks of it and we slide against our will into the portal. Seconds after I watch Karma, yelling profanities like it's the end of the world, get unceremoniously pulled all the way into the energy vortex, I manage to manage the corner of a floorboard, holding tightly to it. Still, my hand was slippery and the pull was very strong and only seconds passed before I was losing my grip.

And that's when the teacher and the rest of my peers rush in and then stop immediately upon entering the threshold. Then my grip slips and I get pulled into the vortex. The last thing I see before everything faded into blissful black is a yellow tentacles stretching and only brushing the tips of my fingers. And then black engulfs me.

Ritsu P.O.V.

Seeing Nagisa getting sucked in, I frantically travel into Nagisa's phone only seconds before we both get pulled into the swirling energy vortex. Once we enter I can feel the phone shutting off and sigh. Hope I made the right choice...

Koro-sensei P.O.V.

Hearing that my student had collapsed in the classroom, I rushed over immediately. Pushing open the door with a bang, I stop in surprise and horror at what I see. Karma, shouting profanities, getting sucked up and disappearing within the vortex. Percy, nowhere to be seen. Ritsu, packing her bags and traveling out of her box. Nagisa, holding on by a hand. And that's when Nagisa's hand slips and he gets pulled into it as well. Moving even faster than Mach 20, using all my force, I make a desperate grab for my students hand. Yet, despite my abilities all I manage to do is lightly brush his fingertips before he's gone. Less than a second later the vortex blips out of existence and I'm left staring at my tentacles in horror. I failed to protect my stusents. What kind of teacher am I?
