Purity

Demons have started falling ill. Sebastian is close to death. Alois and Ciel come together to try and find out what's going on. Why are all the demons suffering? Is it some sort of virus? And how will two boys manage to save their servants?

Our worlds should have never collided. Demons reap havoc amongst the innocent humans. They create a mess within their society. They must be eliminated. Demons and humans cannot co-exist. The demons have to go…

The shadows that hide beneath the rocks must burn and shrivel until they're nothing left but miserable ash. May the soulless life forms turn sickly and unholy until not even bone remains.

…It's time…

"A letter arrived from her Majesty the queen." Sebastian handed the young Earl Phantomhive the note that he'd already opened for him. Ciel read through the parchment and sighed. "She wishes to invite you to the annual fair in London Town."

"Tell her I'm preoccupied. I'm not heading all the way down to London for a fair. I've got more important things to worry about." Ciel stated, placing the invitation onto his desk.

"Well, you never know. You could end up enjoying yourself." Sebastian joked with a slight smirk. Ciel simply shot him a look of disapproval and rolled his eyes. "I'll send word to Her Majesty as soon as possible." Ciel watched as Sebastian turned to exit the room.

As Sebastian reached for the silver handle upon the door, he suddenly felt a vicious sharp pain upon his chest, like someone had lodged a knife where his heart would be. The pain burned like molten and became more and more intense the longer he stood there. At first, Sebastian made no obvious signs of discomfort. He simply clenched his fists, wondering whether the feeling would pass.

Demons are impure, meaningless life forms. They must be deleted!

The pain struck again, only this time, it had impacted his head, like a thousand blades piercing his skull. Sebastian choked and put his hands on his head, silently screaming as the strikes continued to hit his human form. Ciel stood in alarm. "Sebastian? What are you doing?" The demon fell to his knees by the door and couched up a hefty amount of blood. The pain was overwhelming. He'd never experienced anything like it before.

"Sebastian!" Ciel paced to the demon's side and placed a hand on his shoulder. "Sebastian, what's happening to you? Snap out of it!"

The commotion had alerted Mey-Rin, Baldroy and Finnian. They burst in through the door to see the black butler on his hands and knees, shaking uncontrollably, sweat dampening his porcelain skin and charcoal hair. "What's going on?" Baldroy questioned. "Mr Sebastian…"

Ciel had never seen his demon like this. He looked so weak…so pathetic…he almost looked human. He couldn't understand what was causing Sebastian to shrivel like this. "Baldroy, Finnian, carry him upstairs, now!"

"Would you like me to call a doctor?" Mey-Rin asked.

"No…" Ciel knew no form of medication could heal a demon. "Leave it. Just get him upstairs to the bedroom before he passes out!"

They shall shatter like glass and bend like rubber. They will melt beneath the flames of death.

Demons are strong…but believe me…so am I…

Claude stared down in shock at the three triplets who shivered beneath the covers of the bed, sweat covering their entire bodies. Hannah sat beside the three of them, dabbing a damp cloth over their foreheads. "This isn't possible…" Claude examined the three from a distance.

Timber wheezed out a cough and a drop of blood trickled down the side of his mouth. Hannah wiped the blood from his face before it stained his purple hair. "They're burning up. It's like their bodies have caught fire." Hannah stated.

"Demons have no physical need for an immune system. It's impossible for them to just fall ill."

"This isn't sickness." Hannah hissed. "They're…they're dying." Hannah stroked Canterbury's cheek with pity. "I've never seen anything like it."

"…How long do they have?" Claude asked.

"They're staying strong…but from the looks of things, I don't think they'll last much longer." Hannah stood and from the chair beside the bed and turned to look at Claude. "If this is some sort of curse that can only be spread from demon to demon, we'll probably end up like them if we don't figure out what's causing this virus."

Claude adjusted his silver wired glasses. "We need to find the source of the virus, and once we do, we need to destroy it."

"Agreed…" She took one last glance at the triplets in dismay. "We don't have much time."

They shall fall into death and burn in the flames. They shall die feeling the pain of ten-thousand years of torture all at once, as they slowly crumble to dust and ash.

Sebastian lay completely still upon the bed. If it weren't for his breathing, Ciel would have thought him to be dead. Sebastian had been shivering and shifting uncomfortably for hours…when suddenly, he stopped, as though to say he wasn't going to even bother anymore. He was still in pain. The suffering continued, only in silence. Mey-Rin, Baldroy and Finnian stood outside wondering what was going on. "This isn't just a fluke, is it Sebastian?" Ciel said, though he knew Sebastian wouldn't reply. "This would never naturally happen to a demon…which can only mean one thing. Someone's trying to kill Sebastian…and they're doing a pretty good job of it too." Ciel thought out loud, knowing the others wouldn't be listening. He smirked and placed a hand over his eye patch. "Sebastian…I know you can hear me…and I command you to hold out for as long as you can until I find out what's going on. That's an order."

Sebastian began to shiver as a melancholy smirk crawled upon his lips. "Y-yes…my…lord."
