The nights are getting longer and longer as each day passes and we all knew winter would only make things harder than they already were for us. The fact that winters shadow is beginning to loom over us is already making life worse for everyone 'lucky' enough to not be affected, since days are starting to become a few hours of decent sunlight at best. Most days remain cloudy and dark, meaning another day without provisions. 'They' don't like the day; their bodies lacking what protection they once had; making them especially vulnerable to the suns UV rays. The day is the safest time to do whatever needs to be done; gather supplies, search for other survivors or even get as far as you can from populated areas.
This parasite is evil in the deepest of forms. It has no sympathy; it has no mercy. It simply seeks out the next suitable organism in which to latch onto and feed from. There's no such thing as compassion anymore; people you've known for years can be taken over within a matter of hours, leaving nothing but an empty shell of a creature and a never ending need to satisfy its hunger.
It's been half a year since Pokémon began acting erratically and attacking their trainers. Most of the cases originated from the densely populated areas of Unova, before cases began cropping up in and around Johto. At first it was strictly Pokémon that contracted the odd behaviour, but soon it was becoming prevalent in humans too. Coincidentally, those who had been in 'contact' with carriers of the parasite were notable 'offenders' and seemed to be the ones that became infected. This ultimately led to the contamination of other humans, kick-starting the rapid spiralling effect of a mass inter-species contagion.
I've got no idea how many people are still alive. How many people resisted the parasite, or refused to concede their lives at will. I used to have a full team of six, one naturally being the one I've known my whole life. My best friend. This... parasite killed off the majority of Pokémon species instantly, and practically left the rest infected; which is basically as 'good' as. Those who were left are either completely unaffected and fought off the invading parasite, or became carriers of said infection. Carriers then transmitted the infection to humans via... 'distasteful' actions.
The only things that matter about the human race now are; the majority of us were killed outright, the minority are immune and the rest are infected. We have no carriers; we're too inferior to keep it suppressed in such a way.
I'm no scientist. I'm no expert. I'm just a normal guy who was born with a strong immune system. I'm just a guy who's been cursed with staying alive alongside these creatures.
Unfortunately... I've got a long way to go yet...
