The Mysterious Killer

It was late at night at the Afterlife School. There were a group of nine people in the principal's office. They were class SSS or the Afterlife Battlefront. There were seven boys all wearing a tan jacket with an SSS symbol on the right shoulder. There were also two girls. They both had on a white and blue sailor suit and a dark pink tie, and a mini blue skirt. One girl had purple shoulder length hair, sea green eyes, and a black headband with a yellow ribbon on the left side. She had on dark blue thigh highs, and black shoes. The other girl had red eyes and pink hair that reached all the way to her waist with two little pigtails tied with red ribbons and two strands of hair going over her shoulder tied with a white cross symbol. She had black bracelets with chains on each of her wrists, two more black bracelets on her both her thighs, black shoes with stockings, a devil tail, and small bat wings hiding behind her hair giving her the impression of a little devil.

"So tell me any intelligence, Takamatsu?" said Yuri, the girl with purple hair.

"Okay, let's get started with Operation: Tornado."

"Alright then," said Matsushita the Fifth, the big guy with black hair.

"Alrig-," Yuri was interrupted by a loud blood curling scream coming from outside. All the other SSS members were as shocked as she was.

"What was that?" said a guy with blue hair and royal blue eyes.

"I don't know, Hinata," said a guy with red hair and burgundy eyes, Otonashi.

"Don't just stand there!" Yuri yelled. "Let's go! Everyone grabbed their weapons and headed out towards the source of the scream.

"Do you think it's Angel?" Fujimaki asked.

"I don't know," Yuri replied uncertain. "She would never scream or cause someone else, too, but there still the possibility of it being her." Just then they heard another scream.

"We better hurry," said Hinata.

"Whoever's doing this I'm going to kill them a thousand times," replied Noda, the guy with purple hair.

"Yeah!" everyone else yelled out. As soon as they came to the place they all froze in fear and fright. There was blood and pieces of torn bodies everywhere. They were the bodies of the NPCs. It looked just like a horror movie. When they walked a little closer they came to a girl with her back turned to them. She had black hair that reached to her mid-back. The girl also had one a black and dark orange sailor school uniform with a white bow tie, a dark orange mini skirt, white knee-high socks, and black shoes. She looked like she was stabbing something over and over with a katana with black and red hilt, and a red and white sheath.

"What the hell do you think you're doing?!" Yuri screamed. "Stop that!" The girl didn't listen, she just kept stabbing the NPCs.

"Hey! You listen to Yurippe and stop that now!" yelled Noda. She still kept on stabbing. Noda got frustrated with her and threw his halberd at her. Just as it came close to her she caught it… without turning or looking back?

"She barely even moved. She didn't EVEN look. How on earth did she know where it was coming from?" The SSS were all thinking the same thing. The girl stopped and slowly turned around to face them. They all let out a gasp of fear. She was completely covered in BLOOD! The blood was on her face, neck, hands, and on her sword.

"What do you want?" Everyone was frightened by the sound of her voice. Her voice lacked any kind of emotion.

Yuri stepped up and spoke, "Why are you killing the NPCs? Aren't you afraid of disappearing?" The girl just stared at her with no change in her expression. Everyone got out their guns (A/N: I don't know the name of their weapons. I'll try to learn more about them. I'm not good at the name of guns. Watch the anime for more info.) and pointed them at her.

"You are afraid of getting obliterated?" she finally spoke rather coldly. Just then a NPC started walking towards them from behind her. "I, however...," in one swift motion she cut off the NPC's head; blood spilled everywhere, "…hold no such feelings." The Afterlife Battlefront members stared wide-eyed in shock and horror.

"SHOOT HER!" Yuri yelled. All the members of the Battlefront started shooting their guns at her. She dodged every bullet that was shot towards her. The mysterious girl ran up to Fujimaki and kneed him in the gut. He doubled over in pain. The girl kept on her assault on the group. Yuri came up with a plan. "Everyone distract her!"

"Are we going to use that?" Hinata asked tiredly. He was exhausted. The black-haired was just too quick. Yuri shook her head indicating a 'yes'. Everyone started shooting at her again to distract her. The girl was currently engaged in a hand-to-hand combat with Matsushita. She tried to punch him in the chest, but he was faster than she anticipated at first, and he grabbed her both her wrists restraining her. This is what she gets for being over-confident and cocky.

"Let me go, you bastard!" she was thrashing about trying to get out of his hold on her. "Damn! If I wasn't in my human form then this would have been a piece of cake." Just then Yuri shot her with a tranquilizing dart in her neck. The killer instantly stopped struggling then slowly went unconscious.

"What are we going to do with to do with her?" Takamatsu asked pushing his glasses up.

"I don't know," Otonashi replied slightly frightened to go anywhere her.

"Let's take her back to the AAHQ (Anti-Angel Headquarters)," Yuri stated. "I like to ask her a few questions." Matsushita carried her over his shoulders and they headed back towards the principal's office.
