Shinigami?! Well that explained a lot. The more he spoke of the book, the more Shae read over the rules mentioned in the front page. This whole thing was real? She rested her bag on the sink behind her and held the book close. 
"This book.. It takes lives? Just like that." She clicked the fingers on her free hand and waited. Morbid curiosity made the whole thing a little more interesting. If she really did have the power of life and death at the end of a biro, she could rule the planet. "You can see how long I have left to live?" A free hand moved to the top of her head, as if she imagined her remaining days shining vividly above her head.

"A whole world? How many of you is there?" Despite the strange appearance, Shae was slowly overcoming the terrifying experience she'd had earlier that afternoon. "What happens if I don't want this anymore?" She asked, tucking the book back into her bag. She pulled her bag strap over her shoulder and looked towards the door. No doubt the police would be here by now. There was no way to trace the death to her, as far as she knew. Regardless, she didn't need the authorities on her back. Not if she was carrying the weapon in her hand. 

She moved over towards the bathroom door and peered a head outside. The hallways were quiet now, but downstairs she could hear the sound of sirens and commotion coming from hundreds of students outside. 
"Is there anything else I need to know?" She asked, lowering her voice. After all, if the Shinigami really was invisible, she would appear to be talking to herself. Shae walked along the hallway, peering out the windows are she walked. They'd already barricaded off the school entrance, and by the looks of things, the body was already in the ambulance.
