A/N: Hi there guys, its been a while since I last wrote something. They say that the 'dere-dere' characters are the cutest which is actualy true but they are also the scariest when they turned psycho. So with that in mind, I tried writing this story featuring a psychophatic Kotori but unfortunately, this is my first time writing a horror story so please don't criticize me too much. And oh a heads up, I only used a BlackBerry Curve to write and post this story. Its just experimental so I apologize if there are spelling and grammar mistakes. Oh well, without any further ado. I present you PSYCHOPHATIC BIRD.

"They sure are late nya." Rin said with a worried expression. The group was supposed to start their practice two hours ago but the only members that are currently present are Rin, Hanayo, Honoka, Umi and Maki and they are still waiting at the rooftop. The third years and Kotori haven't showed up yet and they are starting to get worry about them.

"Are they even coming?" Maki asked folding her arms.

"Aren't you worried about them nya?"

"O-Of course I'm worried about them too." Maki answered looking away. 'Specialy about Nico-chan.'

"I'm really worried about them. They're not responding to our messages or picking up our calls. We should really go looking for them." Honoka siad looking at her phone. She already sent countless messages to the others but she didn't even receive a single reply. She also tried calling them but none of them picked their phone up to answer her call.

"We really should. Should might have happened to them." Umi said and the others nodded.

They were about to leave when the door opened and revealed a bloodied Kotori. Her clothes was dyed with red. Her hair and face and other parts of her body are splattered with blood, but the scariest thing was the large bloodied kitchen knife that she was holding.

"K-Kotori-chan..." Honoka took a step blood and can't believe what she was seeing right now.

"I'm sorry for being late." Kotori said and gave the sweetest smile that she can give.

"Where are the others. What did you do to them?" Maki asked trying to hide her fear by acting tough.

"Nico-chan, Eli-chan and Nozomi-chan? I killed them before going here." Kotori casualy said like it was nothing.

"You're joking right, Kotori-chan?" Honoka asked unable to believe what her childhood friend just said.

"I'm telling the truth Honoka-chan. I did killed them before going here." Kotori said and took a step forward. Maki stepped infront of Hanayo and Rin to try and protect them.

"You're out of your mind." Maki said sternly. Kotori suddenly dashed forward and made a horizontal slash cutting thru Maki's throat.

"You think so?" Kotori asked Maki who was squirming on the floor. Her throat was cut open and blood was flooding out of the wound and she was trying to cover it with her hands but it was useless and her blood was starting to pool around her.

"Maki-chan!"

"Maki!"

"Maki-chan!"

"Mak-" Rin tried to shout Maki's name but her sentence was cut when Kotori turned to her and stabbed her on her stomach.

"Shhh. You should stay quiet Rin-chan." Kotori said and twisted the knife slightly to the right making Rin scream out in pain.

"Rin-chan!"

"Kayo-chin... Run!"

"Rin-cha-"

"Run Kayo-chin!" Hanayo was speechless. Honoka and Umi grabbed her hand and dragged her.

"You think I'll let you escape?" Kotori tried to run after the three but Rin hugged her. "Please let go of me Rin-chan."

"I won't let you lay a finger on Kayo-chin." Kotori sighed and violently twisted the knife causing her the cream out in pain. Kotori took this as a chance and pulled the knife out before pushing Rin away but she was able to grab Kotori by the hand causing both of them to fall on the floor.

Kotori clicked her tongue in annoyance. "You..."

"I won't let you-" Rin's sentence was cut when Kotori raised the knife above her head the brought it down on Rin's chest killing her.

"So annoying." Kotori said and stood up. "Now I need to search for them. This is going to be a pain." She said and went after the three.

"What's got into Kotori?" Umi. She, Hanayo and Honoka are hiding at the Home Economics room.

"I don't know." Honoka was trebling while hugging Hanayo tightly. Hanayo was in a state of shock.

"Rin-chan... Rin-chan... Rin-chan..."

"For now let's try calling the police." Umi said and fished her pocket for her phone to call the police. She dialed the police hotline and hit the call button. It rung for a few time before someone picked up.

"Tokyo Police Department, how may I help you?"

"Honoka-chan~... Umi-chan~... Hanayo-chan~... Where are you guys?" Kotori calls out to her prey while walking slowly down the hallway with her knife in her right hand dripping with blood.

"Oh, Kotori-chan." A familiar voice called. It was Hideko, one of their friend. She happily approuched Kotori. Kotori's back was turned towars her so she wasn't able to see her appearance. "Woah what's with the-" Hideko wasn't able to finish her sentence when Kotori turned and stabbed her on the base of the neck.

Hideko dropped on the floor lifeless. Kotori resumed her search and she came upon the Home Economics room. She looked at the room sign before reaching for the door handle.

They heard the door opened and someone entered.

"Anyone here?" The three of them froze upon hearing Kotori's voice. They remained as quiet as they can. "No one? Fine then." They heard Kotori opened something, probably a drawer. After few more moments, they heard a noise that sounded like pressurized air escaping from a container followed by a smell that made their blood run cold. It smell like...

"Propane gas!" Umi shouted and came out of hiding. Honoka and Hanayo went near the window.

"Oh Umi-chan. Just as I thought, the three of you are hiding here. Kotori siad and turned one of the stove on. Their eyes went wide and they didn't had anytime to react when the fire from the stove ignited the accumulated gas inside the room.

BOOM

Honoka and Hanayo was thrown out of the window by the shockwave from the explosion. Since the home economics room was at the second floor, their landing was as painful as it can get when you are thrown out of a second floor window.

"U-Umi...chan..." Honoka was lying on the ground. Her limbs are dislocated, her whole body was in pain and her vision was strating to fade. The only thing that she can hear was the ringing in her ears and a faint sound of sirens. "Umi..." Honoka tried to call for her friend before her consciousness finally left her. The last thing she saw was the burning home economics room.

A few days later

A police officer was reading a pile of police report about teen aged girl found dead at different parts of Tokyo. The incidents are reported to had occured at the same day and the authorities are closely investigating all the cases in order to solve them.

Yazawa Nico- found dead on her apartment with her three siblings, Kokoro, Cocoa and Kotarou Yazawa. All three of ther had their hearts reaped from their chest. Evidence indicates that there wasn't a force entry because the door lock was still intact. Investigations are still being conducted to gain kwoledge about the assailant's identitybut the investigators believe that the victims personaly knows the assailant.

Ayase Eli- found dead inside her room with her sister Ayase Arisa. Both of them have multiple stab wounds. Forces entry wasn't observed at the scene indicating that the victims personaly know the assailant that was most likely one of their friend. Farther investigations are still being conducted.

Toujou Nozomi- Found dead at the bottom of the flight of stair leading to the shrine where she is working as a shrine maiden. The cause of death was multiple head trauma which she got when she fell down the stairs. Evidence such as a pair of bloodied hard print on her back indicates that there was a foul play. Farther investigations are still being conducted.

Nishikino Maki- found dead in a pudle of her own blood at the roof top the main building of Otonokizaka High School. Her throat was cut open. Her classmate and clubmate Hoshizora Rin was also found on the same roof top with a stab wound on the abdomen and chest. The cause of death was the stab wound on the chest area. Investigators are suspecting that the two were killed by the same assailant. Farther investigations are still being conducted.

An explosion occured at the Home Economics room of Otonokizaka High School. Two bodies were found burned inside the room. The two bodies were badly burned beyond recognitions. Dental records confirms the two to be Sonoda Umi and Minami Kotori, both second year students at the said school. The fire department identified the cause of the explosion to be a gas leak. The investigators are still trying to identify if the explosion was an accident or intentional. Farther investigations about the incident are still being conducted.

Kousaka Honoka- found dead at the side of the main building of Otokizaka High School. The arangement of her body and the multiple burn marks that she had indicates that she was inside the home economics room at the time of the incident and was probably thrown out of the window by the force of the shockwave from the explosion. The cause of death was multiple internal bleeding. Her friend and clubmate name Koizumi Hanayo is still in a critical condition because of a major head trauma and multiple internal bleeding. Her body was found next to Kousaka's and is also hyphotisize to be inside the home economics room at the time of the incident and suffered the same fate as Kousaka. The authorities are treating her as an eye-witness and the key in solving the case. Farther investigations are still being conducted.

A closed circuit television footage shows Minami Kotori, one of the victims found dead at the home economics room incident walking down the second floor hallway of Otonokizaka High School with a bloodied clothe and a bloodied knife at hand. The footage also shows another student of Otonokizaka only know by the name Hideko aproaching her. The next scene on the footage shows Minami stabbing her with the knife she was holding. A appearance of the video pointed Minami to be the primary suspect for killing Nishikino and Hoshizora. Authorities are still investigating if she is also the one who killed the Yazawa siblings, the Ayase sisters and Toujou Nozomi.

A/N: And that concludes the story. I hope you liked the idea of Kotori turning into a mad psycho. I actually got the idea after reading a few Love Love zombie fanfics so I hope you enjoyed it. Please feel free to leave a feedback about my story. I would be more than happy to read them.
