"You will know"
Koi stirs, twitching as he awakens. His eyes open slowly. He was in a classroom.
Augghh! He thinks. What class did I fall asleep in? He could see other student bodies around him, but in front of him was a blackboard. SHIT! I'm in the first row and I fell asleep?
He sat up with a start, hoping he could somehow play it cool and go undetected. Yeah right. As if a teacher would miss the opportunity to humiliate him. The sleep was so heavy in his eyes that he felt he might actually fall back asleep right there and then, but he had to force himself awake. Force himself straight.
The shape of a teacher was to his left. It didn't move. He waited to be scolded as he blinked the rest of the sleep out of his eyes. He waited for the other students to laugh at him.
He glances to his left and sees another student playing with their hair and giggling at their desk. Strangely, he wasn't paying Koi any mind. Koi blinked a few more times, thinking this student looked familiar, but couldn't quite place his name.
Koi finally cleared his eyes enough to see that he was staring at himself as if through a mirror. But he was laughing, and his hair was pink instead of blue. Koi used his hands to rub his eyes and looked again. He watched himself receive a note from another student. And when Koi's eyes fell on that student, he realized it was also Him. Light blue hair and all, with a stack of books on his desk, passing notes to pink-haired self.
Koi jumped as he felt something hit his neck. A spitball. Grimacing at the grossness, Koi turned around and came face to face with himself again, except this time, it was a female version of himself.
She had pink hair pulled back in pig tails similar to Carrots, and she snickered at the stunned and confused look on Koi's face. Then she gave him a wink and blew him a kiss. Koi quickly turned around, blushing. As he did, he noticed that while the classroom had lots of bright sunny windows, there were no doors, at least not on the left side. He turned to search his right and came face-to-face with another version of himself. Black hair and the megenta eyes so deep and violent it scared him. It creeped him out to the bone.
The eyes of this scary, rigid Koi were focused up front, and Koi followed his gaze, finding the teacher standing at the front of the classroom and instantly recognizing it was KETSU. He knew it was Ketsu just by the form and by the aura, because he couldn't see Ketsu's face. It was an unsettling blur, as if Koi had taken a cheap, kids' eraser shaped like grapes and smelled the same, and tried to erase his face, but did a poor job of it.
The Ketsu blur stood rigid at the front of the class. Koi inhaled, for fear the beast would extract his revenge and jump out and slaughter him at any moment. He wondered why the other Koi didn't seem scared. They hardly paid Ketsu any mind.
Koi saw his cheerful personality, smiling and laughing happily with a lily in his hand. The lily was the same pink color as his hair. He played keep-away with it as the female Koi jumped out of her seat and tried to wrestle him for it. She reached for it and purposely put her boobs in his face and then licked his nose. She was leaning over so far trying to get the lily from him; her skirt was hiked up to a dangerous level, and Koi wondered for a moment why his feminine side seemed to be a bit of a slut. This was definitely something he would have to discuss with his platoon of therapists.
Behind the wrestling Koi's, curious Koi peeked over a book to see what the duo was up to as if studying them.
Koi could feel dark Koi right next to him. He was terrified that his eyes were, in fact, on him. He refused to turn and see but just knew he was there. Between Ketsu and dark Koi, Koi wanted out of this place, but he saw there were no doors. A sense of dread fell over him and wrapped him up like a fall sweater.
"You were perfect, Koi. A prism. Each personality is a different lens. I could test spells through you without consequence. You broke, but you reformed. Again and again. That's what made you useful."
"I was perfect?" I muttered, somewhat in disbelief at what I was hearing. I had never been called perfect for anything.
It was the disembodied voice of Ketsu giving me a lecture. I was perfect. A Prism. My multiple personalities. My Mental Illness. What had gotten me kicked out of home, teased all my life, and sent me to this horrible "school." Ketsu not only knew about it and understood it, he also used it. He could test spells through my multiple personalities, and the main me would never know, would I? How would I know what was going on with Cheerful me, Girl me, Curious me, or the Darkling? When they took over my body, the Host me went to sleep. I had no idea what they were up to. He's right, it was perfect. Except what if it was a bad spell?
Koi could FEEL dark Koi glaring at him. His eyes were wide with anger and madness, and he was boring into the back of Koi's head to the point he could feel the heat.
"But you made a mistake. You started remembering. You started feeling. That's when you became dangerous."
I started waking up, you mean. Koi thought in a flash of anger. I started realizing you were manipulating me. I didn't know how, but now I understand it. Now I know indeed. You were casting spells on my different personalities, hiding your work within me, testing them out. Seeing what would keep and what would further break me.
And then I stopped it, didn't I? I started to feel it. Feeling came to me, I was no longer as numb as I used to be. And I banished you to Riconzi. But why are you back?
Then Ketsu said the words that chilled Koi to the bone:
"That's the one I'll keep."
And he pointed, past Koi, to the beast that sat on Koi's other side.
"No," Koi thought. He didn't want to be trapped in that personality forever. The one that helped the most PAIN. The one who had the explosive anger. Anger so material it burned away all his emotions and left him the numb sack of dead meat again.
But before Koi could do anything, he heard screaming. The other Koi were on fire, being burned away. And before he could let out a scream, flames engulfed him too, and he woke up in his bed, safe and sound. With just the window to his side open, showing the sunny bright outside and daylight. And his alarm blarring telling him he didn't have a moment to rest and reflect. He had to hurry up and get to class.
