Chapter 1: The Sister
It would be easy to believe, easy to think that the girl might kill herself. Dislike by boys and within striking distance from home, Kagami Hiiragi was the perfect victim for the first of many "accidental" deaths.
These thoughts ran through her head as Tsukasa Hiiragi sat at her desk in Class B. For many years Tsukasa had been nagged on and made fun of by people that she used to regard as friends and family. However, she was reaching her mental limit and decided to put an end to it.
"Everyone believes that I'm just a cute little airhead," thought Tsukasa, "Little do they know, that these days will be their last."
That night, while her sister was busy with her homework, Tsukasa began planning her first attempt at murder. She that her sister would be a formidable opponent in a direct conflict so she devised a sneakier idea.
"I could try hanging her from the shower rod in our tub," she thought. "However, the body would be found as soon as someone else tried to take a shower." Sensing the plan was doomed to fail, she continued her planning. Six hours later, the plan was complete, and it would all happen tomorrow evening.
"Good morning Sis!" Tsukasa said as she rushed to the breakfast table early the next morning. She knew that to keep Kagami in the dark, she would have to be her normal self throughout the day.
"Good morning Tsukasa," replied Kagami, wondering why her sister was up so early. "Are you ready for school?"
"Yup sis, Let's go!"
That evening after the rest of the house had gone to sleep, Kagami sat in her room reading one of the new manga that Konata Izumi had lent her. It was a new horror volume in which the killer was the protagonist's sister. It had a great plot and suspenseful panels. Little did she know, but Kagami's world and that manga were about to become very real.
Since her sister seemed to be preoccupied with the manga in front of her, she did not hear the door open quietly as Tsukasa crept in.
"Sis, can I come in?" asked Tsukasa as she leaned through the door. Slightly startled, Kagami immediately hid the manga and covered it with her pillow.
"Sure, come on in," she responded. "What do you need?" Her back to Tsukasa, Kagami could not see the murderous intent in her sister's eyes as Tsukasa's pupils trained in on her target.
"Oh nothing Sis, just wanted to talk." With that Tsukasa grabbed Kagami, slapped a piece of tape on her mouth, tied her wrists behind her back, and threw her on the bed.
"Mumble, Mumble!" Kagami screamed into the tape on her mouth.
"Oh don't you worry Sis, it will all be over soon. You know how you and Kona-chan are always making fun of me?" Tsukasa inquired of her sister. "Well, I've had enough and now I'm putting an end to my suffering through putting you down. All I had to do was find the right way to do it and make it look like a suicide."
Kagami began to mumble things that may have been some sort of apology, but all Tsukasa could hear was gibberish because of that lovely tape that fit so well over her "older" sister's mouth.
"Shut up, you self righteous bitch!" said Tsukasa, grabbing Kagami by the throat. Tsukasa dragged her sister to the middle of the small room, under the hanging fan, and began to tie Kagami's long twin tailed hair into a noose shaped around her sister's throat. She reinforce the "hair noose" with rope to make sure that it actually did the job. She then proceeded to tie both the hair and rope from one of the blades of the overhead fan. Tugging on the hair to ensure the security of the noose, Tsukasa ripped off the tape over her sister's mouth and walked over to the switch on the wall.
"Wait Tsukasa," pleaded Kagami, "Let me down and I promise that we won't make fun of you anymore."
"No, I've had it!" Tsukasa responded to her sister. "After tonight, you won't be able to make fun of me ever again!" With those final words, Tsukasa flipped the fan switch to ON. At first the fan had trouble with Kagami's weight, but it eventually started to spin, slowly at first, but soon it gained speed. As the blades spun faster and faster, Kagami could feel the noose tightening around her neck.
"Tsukasa! We never really meant any of those things we said," Kagami choked out, but she could tell that her sister was already too far gone for anything she said to have any effect. Realizing that these may be her final moments, Kagami began saying her goodbyes to her friends and family. Suddenly, her thoughts fell silent. "Snap!"
That was it; the sound that Tsukasa had longed to hear. The sound of the breaking of her sister's neck was a long awaited relief. She flipped the fan switch OFF and the blades began to slow. After the fan had stopped, she checked to see if the deed was done. The proof she wanted materialized in the form of a puddle of urine and feces on the floor, compliments of Kagami's loss of bowel control. Lifeless, her sister's body hung in the room for the rest of the night. Satisfied with herself, Tsukasa cleaned herself up and went back to her bedroom.
Tsukasa awoke to the horrified screams of her mother's voice.
"What is going on here!" cried Mrs. Hiiragi. "My baby girl, oh my girl is dead." Her sobs rang through the house like the sound of morbid church bells. While Mrs. Hiiragi continued with her sobbing, consoled by her two elder daughters, Mr. Hiiragi cut down his daughter's lifeless body from the fan and laid her on the bed.
Later that night, Tsukasa snuck into Kagami's room. Walking over to the bed, she saw her sister's body lying there. An air of satisfaction came over Tsukasa's body as she reveled in the fact that she had just completed the first step in her plans. Now, she would take out the rest of her group, Konata-chan and Miyuki. Somewhere, deep inside the confines of Tsukasa's mind, the real Tsukasa cries.
