Karoshi - Death by Overworking

Harry let out a heavy sigh as he looked at the large pile of paperwork in front of him, no matter how many times he managed to reach the last page he always found it to suddenly become a large tower of paperwork almost touching the ceiling within a second without him somehow noticing. Letting out a sigh Harry raised his hand and stressed ran it through his short messy black hair trying to get rid of the large headache that had formed as soon as he had woke up that morning and it still had not gone, nothing he tried to do got rid of it.

"Whoever said that things will be nice and peaceful in eight years time after I had defeated Voldemort must of never of heard of the attack of paperwork," Harry muttered to himself with a scowl on his face when he suddenly noticed that he now had two piles of paperwork on his desk waiting for him to complete.

Letting out a low groan Harry finally allowed his quill to fall out of his hand and onto the desk with a soft thud as he tiredly turned and looked at the analogue clock that rested on the wall, it was 2am in the morning on the 31st July. Realising just what this meant for him Harry let out another loud groan and turned to bury his head deep within his now folded arms.

'It seems that I am going to be spending my 25th Birthday alone in my office working again' Harry thought with a depressed sigh as the fact that he had only an hours sleep in the past four days was finally catching up to him 'At least I won't have to suffer through that horrible silence at home...'

Images of his friends leaving him alone and lost as they got on with their lives flashed before Harry's eyes, Hermione and Ron getting married, Luna and Neville going off to hunt for some strange type of plant on the other side of the world, Colin and his brother creating their own photography business together, the Weasley twins working on making their joke shop into a chain with each new shop becoming more and more successful than the last, and Remus finally settling down with his lover Tonks and getting ready to start a family on their own and Ginny happily engaged to her future husband, Dean.

'I'm so lonely' Harry thought tiredly as he lifted his heavy head up and propped his chin on his arms, not wincing as his sharp bony chin rested on his thin bony arms 'At least the never ending paperwork I have to do as part of my job as the second in charge of the head of all departments should keep me too busy for me to notice the pain.'

Without realising it Harry's eyes slowly grew heavier and heavier until he found himself floating away from the exhaustion and pain that littered his overworked body and into a peaceful relaxing sleep never noticing the shadowy figure standing in the shadows of the room with a worried frown on his face.

"I cannot allow this to continue," the shadowy figure muttered to themselves in a smooth Italian accent, "If this is the person...the one that the ninth thinks will be able to help Dino and Tsuna..."

Taking a deep breath a pale slim hand reached out from the shadows and reached upwards only for a few seconds later a small green lizard to suddenly come crawling out of the darkness with large yellow eyes and come to a stop on hand. Once the small green lizard was safely on his hand. As if by magic the strange green lizard suddenly changed shape into a green and blue gun and the gun was aimed at the sleeping figure at the desk.

"Time for my new bullet," the man said softly as he pulled the trigger with a hidden smirk.

As the bullet left the gun a bright soft red light sprayed out around the bullet with bright blue sparkles, as it headed on its path towards the sleeping Harry Potter. Just as the strange bullet was about to hit the raven haired man a large thick cloud of red smoke covered the office preventing the shadowy figure from seeing anything through instead of frowning in confusion the shadowy figure gave a dark knowing smirk.

"Good, it works," the shadowy figure with in a pleased tone as the red smoke slowly disappeared, "Now onto stage two of the plan."

Until the next prompt!
