[B][U]And the Screaming Begins[/U][/B]

Hiro munched on her meal an drank her sugary drink enjoying herself in her secluded spot. She checked her phone to see what time it was an found she had a few more minutes before she had to head off to her next class. 
Cleaning up her mess she gathered up everything in the grocery bag she'd brought it all to school with and headed for the stairwell. She went down the stairs three at a time her skirt flying with each leap but she didn't care because the stairwell was always empty. When she reached the bottom she opened the door and some guy she didn't know tried to grab her.
Hiro danced out of his grip and turned to face the Ecchi an crew him out. That was when she noticed several things all at once.
First the perv had two friends, Second there was a familiar smell in the air and Last that he an his friends appeared to be in horror Cod.
[B]"Really funny, ha, ha, jokes over"[/B] she said as the three began shuffling towards her
It was at about that time that Hiro discovered the source of the familiar smell; it was Samiko Misha a girl she knew from science class and the smell was blood.
Hiro screamed before she could stop herself because of the horrible way Misha looked. Her throat was torn open an blood everywhere and her school blouse was also ripped exposing a mangled breast.
Never one to hesitate in choosing an action Hiro turned an ran. She was seeking a teacher or any other adult to expose the crime to.
Her feet powered her through the halls at breakneck speed till she slipped and fell sliding into a mop bucket.
As Hiro struggled to her knees she realized she'd slipped in a huge puddle of blood and to add to her misery she was now covered in mop water that smelled of vomit.
Her hand touched on the thick handle of the mop that went with the bucket and she gripped it tightly as she stood. 
As a practitioner of Ryūkyū kobujutsu the Okinawan martial arts Hiro was taught by her grandfather that all weapons whether makeshift or intended shared certain traits that she should recognize. The mop was no longer a mop but a Bo staff or potential spear.
She quickly unscrewed the handle from the base then took a stance to face a half dozen of the clearly psychotic students in horror Cos as they began to move towards her. With a spinning flourish to distract them from her true purpose Hiro spun her mop handle staff and smashed out a hall window. Sweeping the staff in a circle. She knocked the remaining glass from the frame then leapt out the opening and into the school yard between buildings.
What she saw outside showed her that this was no small localized event but was everywhere on the school grounds.
She looked all around herself and saw everywhere students attacking an killing students.
"High ground, I need high ground to see if I can find allies and an escape route from the school" she thought as she ran towards the main building on the Academy grounds.
Again rather than take a door Hiro smashed her way through another window. She was headed for the clock tower which at it's top was three stories taller than any building on the school grounds. She was sure that from there she could see a good distance an formulate a plan.
She opened the stairwell door and was momentarily surprised to find two of the crazy students inside ready to attack. One of her foes managed to grip Hiro's blouse an tried to use it to pull her towards him. She was forced to lean back hard to rip open her blouse leaving him a handful of cloth.
Now really ticked off with everything that hand happened to her Hiro swung her Bo in a skull crushing arch dropping the ecchi creep with a satisfying crack . His friend a girl Hiro didn't know stumbled forward forcing her to deliver to the girl a jaw breaking upper stroke followed by another skull cracking over hand swing.
"Great, I stink of vomit, I'm covered in blood an niow I'm a flasher" growled Hiro as she kicked the male the headed up the stair to the tower roof.
On her ascent Hiro encountered three more of "Them" and dispatched them with vengence.
She pushed open the door and exited quickly ready to defend herself from any lurking on the roof of the clock tower.
