Prologue: Chapter 4

   The next week, Iida was teaching Nakajima Akemi and Takamizawa Kyoko's class math in the CAI Room. Perhaps it was because he was there to witness the failure of the demon summoning, but Nakajima was looking at Iida with a defiant stare. Until now, he would never have acted like this. Trying hard to ignore him, Iida continued his lesson.
   "Now I'm going to have you take an interactive test using the host computer. However, this test won't affect your grades in any way. Through your interaction with the computer, I'd like you to get a little bit more familiar with any weak points you may have. Begin entering your commands as soon as I give the signal."
   The students all affixed their eyes to their screens and silently started answering the questions given them, as the host computer started diligently recording their individual responses.
   Once use of CAI spreads, things will get a lot easier for us teachers. Though if it becomes too widespread, the time may come that we teachers aren't neeeded any more... Iida carefully watched over his class while relaxing a bit.
   All of a sudden, as if coming from the depths of the earth itself, a low, rumbling voice sounded and shook the CAI room.
   "Yod, Heh, Vav, Heh."
   The magnetic tape of the host computer started spinning wildly and the screens of the computers in the room started changing rapidly. Eerie colors and strange images flashed onscreen, and strange letter-like symbols appeared and disappeared. The students said nothing, but remained transfixed to their screens as if entrhalled.
   "Nakajima, this is your doing, isn't it? Come on now, there's nothing wrong with a little mischief once in a while, but there are limits!" Twisting his face into an dark scowl, Iida started to walk over to Nakajima's seat, but the moment he started walking a student in the first row stuck his leg out into the aisle, tripping the teacher and causing him to clumsily fall forward. As Iida tried to get up, two more students slammed into his back, pinning him to the ground and twisting his arms behind him.
   "Wh-what are you doing!? Stop this at once!" Taken aback at the sudden hostility of his students, Iida struggled to lift his head up while crying out. The other students, staring ahead with glazed looks as if in a trance, stood up from their seats. Three male students left the classroom, and the others gradually started to surround Takamizawa Kyoko.
   Her face drained of color, Kyoko stared dumbfoundedly at her classmates surrounding her. Her catlike eyes were full of fear, her lips trembling up and down but held shut as if sewn together. A male student with thick glasses touched her chest, and as if freed from a curse, Kyoko lept up onto the desk.
   "Stay away from me, asshole!" Kyoko yelled out desperately, whipping out a razor blade held between her thumb and middle finger.
   "Stop, Takamizwa. Run!" Iida's shaking voice echoed throughout the classrom. But Kyoko merely took a sidelong glance at her restrained teacher, spat, and swung her razor at the student that had touched her. The student's glasses flew off, and his split cheek started oozing fresh blood. But the student did not falter a bit or even try to wipe off the blood, but obstinantly grabbed onto Kyoko's left ankle.
   "Let go of me, asshole!" The razor slashed open the student's temple, and then lodged into his blood-soaked arm, breaking in two. Taking advantage of Kyoko's surprise, another student grabbed her left angle, and the two students now gripping both her legs raised their arms, hoisting her up in the air and dangling her upside-down. Her skirt fell down around her waist, revealing her white legs. Kano Miyuki, one of the most beautiful girls in the school along with Kyoko, walked up, put her face in between Kyoko's legs, and bit into her inner thigh. Bending backward in pain, Kyoko attempted to fight back, flailing her arms around like an animal caught in a trap, her drooping hair swishing wildly around, but several students knelt down by her head and started to twist her neck around.
   "Stop! Stop this!"
   As Iida cried out with tears in his eyes, a cold voice spoke.
   "Professor, it's too late." Nakajima, who had been at his computer entering commands the whole time, looked at Iida with a sarcastic smile on his face.
   "Ooh..."
   With a meager cry, Kyoko's legs spasmed two or three times. Without even attempting to wipe the blood from her face, Miyuki looked up and the two students holding Kyoko in the air let go of her legs. As Kyoko's twisted, lifeless body dropped to the floor, the circle of students started to break up, leaving her behind.

   Right about that time, the door opened, and the three students that had left earlier entered the room, Kondo following behind them. After hearing that Kyoko was being ganged up on and verbally harrassed by her classmates, Kondo came with a mind to teach the "know-it-alls" of the gifted class a lesson. However, the classroom was completely silent, and not at all what he was expecting. The three students led the perplexed Kondo to the center of the room, then quickly moved away.
   "Oh my god..."
   Seeing Kyoko's corpse, Kondo was dumbfounded and words escaped him for a moment. The students in the classroom surrounded him, as if to cut off his path of retreat. At that point, Kondo probably could have gotten away had he set his mind to it. But with his mind clouded with shock and anger, Kondo didn't realize just how dangerous a position he had walked into.
   "You bastards, what have you done...who killed Kyoko!?"
   His body shuddering in rage, Kondo's furious, bloodshot eyes turned to the students. But the normally meek students, who would usually run away if Kondo merely looked at them, showed no signs of fear, and returned his harsh gaze.
   There was something seriously strange going on here.
   At that moment, a groan sounded. Looking in the direction of the voice, Kondo saw Nakajima standing over Iida with his foot pinning the teacher's head to the ground.
   "Nakajima...?"
   Not evening imagining for a moment that such a genius pretty-boy could be capable of something like this, Kondo was completely taken aback.
   Iida called out to him from the back of his throat. "Kondo, run! Everyone's gone mad!"
   Called back to his senses by the teacher's voice, Kondo howled like a wild animal and charged Nakajima. But right before he reached Nakajima, a dozen students jumped on him and pulled him to the ground. Struggling with all his might, Kondo knocked off the students clinging to them, punching and kicking any that got close. But even with their foreheads split and their ribs shattered, the students picked themselves off the floor as if they felt no pain at all, and fiercely grabbed onto Kondo. One of them picked up a computer monitor and hit him hard in the back of the head with it. Kondo's vision blurred with the shock of the blow and started to stumble, and in that instant, the students pulled him to the floor again and restrained his limbs.
   "Shit, let me go! I'll kill you!!"
   Looking at at Kondo vainly struggling against the students, trying to get free, Nakajima's handsome face twisted into a cold smile.
   "Actually, you're the only one who's going to be killed here. I was hoping to have Kyoko be your executioner, but as you've seen, she's already died. So I've been nice enough to have Miyuki do the job for her; you should thank me."
   Cradling his chin in his hand as if in thought, Miyuku kneeled down near Kondo and brought her face close to his, her chin still covered in Kyoko's blood. Her warm breath caressed his cheek. Kond's body stiffened up and shivered a bit, and in that instant, the knife in Miyuki's hand flashed and was drenched in crimson. A gurgling cry came out of Kondo's severed windpipe, and with his eyes still open, his head folded backward with a sickening crunch.
   "Now then, Professor." Nakajima crouched down and looked into Iida's face.
   "What do you think, Professor? You see? My demon summoning experiment wasn't a failure. That day, a demon really did appear--inside the CAI host computer. We just didn't realize it. When I was in class here in the CAI room yesterday, the demon sent me a message: "KILL! I UNDERSTOOD" He can't escape from the computer, so he used group hypnosis to control the class. By the way, Professor, I promised to give three souls to the demon. Kyoko's, Kondo's, and one other..."
   For an instant, Nakajima's eyes glittered with an emotion like pity. But as if to surpress it, he pressed his lips together and stood up.
   "W-wait, please wait..." As Iida desperately wheezed and struggled, ten students dragged their feet along the floor, slowly approaching him.
