Summary: Catherine eats human food but she does indulge in some demonic sustenance as well. When Ciel sees her in the act, he feels somewhat fearful about what it'll be like for him. But if you leave it all to a demon witch, I'm sure everything will be fine…

Elizabeth was sound asleep in her room in the Phantomhive Manor and Sebastian had just prepared his own master for bed as well. Ciel was sending him on an investigative errandso he planned to leave Catherine in charge. She only slept two hours. If he asked, she'd gladly wait to sleep later after he had returned and the Phantomhive Manor along with its inhabitants were completely secure.

Two eyes flickered sharply. Two otherworldly beings sensed the intruders long before they stepped into the Phantomhive grounds. Sebastian sighed, sure that his sister knows the situation as well. He flipped out his pocket watch, calculating how late he'll be. A smaller hand covered it.

'I'll handle it. You go on your errands.' Catherine reassured with a mischievous smile. Blood would be spilled tonight. Sebastian didn't need to think twice. Catherine could handle a bunch of humans easily. It was only certain other demons she had issues with.

'Thank you, sister.' He said simply, disappearing from the area. Catherine peeled off her gloves, her eyes glowing red. She smelled something succulent amongst the ranks of the enemy. Nothing Sebastian would have bothered with since he was focused on Ciel.

She moved out to the lawn with demonic speeds, half-frightening the intruders. 'I do apologize but you will not be able to seek an audience with the master and lady tonight.' She murmured with a slow smile that entranced the enemy. 'They are already asleep.'

She sensed the soul immediately. He was the auburn-haired boy, barely a man and holding a regular handgun. His soul was twisted and tortured, simply mouth-watering even if he was incomparable to Ciel, he would make a good meal. She'd save him for last. It would be all the more delicious if he watched everyone die first. 'Fire!' A man shouted.

Not one bullet had a chance to leave their cases. The leader shivered as he stared at his men, some bloodied, some merely had their necks broken. The auburn-haired boy shook were he knelt, unbelieving of what he had seen. A beautiful woman who had killed an entire squad of trained assassins. His mind screamed 'inhuman!' Catherine had broken the leader's hand, forcing him to release his gun. Her hand was over his mouth. She could feel his fear. It made her excited.

'You shouldn't be so loud. It's very rude especially after dark.' She chided with a dark low laugh. Her other hand slid down the line of his throat. 'I'll have to make sure you stay silent.'

She dug her fingers through the flesh and ripped out the voice box. The scent of blood was intoxicating. A bullet was fired. The auburn-haired boy had gathered his senses and tried to shoot her. She swung the body of the leader in the way so she wouldn't get hit. It would be troublesome to have to mend her dress. But blood did splatter over her, some on her face. The sound was loud. She dropped the body as she licked a drop of blood of her lips.

She half worried that Ciel or Elizabeth had awakened. But she didn't realize that Ciel was already awake. He had been watching her the entire time, likening her to Sebastian. She killed in a similar manner. He watched as she approached the boy with a predator's gait. Ciel had never seen this. If she had known, she would've stopped. But she didn't.

'You smell delicious.' She purred, kneeling on the ground before him and grabbing his chin so she could study his face. 'You poor thing, you must've felt so much pain in this life.' She said in mock sympathy. He fell for it completely.

Her red eyes mesmerized him. 'Yes.' He answered.

'Would you like me to take you away from this life?' She asked softly, stroking his face.

'Yes.' He repeated, probably not even thinking about his. She grinned with her fangs peeking out and kissed him briefly, getting the taste of his soul. Ciel began to shake as he watched her devour the soul, the man screamed but once and then it was drowned out by the sickening sounds of Catherine feasting on him. When she released him, he fell with unseeing eyes that stared straight at Ciel. The young earl choked.

Catherine spun around, her red eyes making Ciel jump. He took a few steps back from the balcony, intending to enter his room but he bumped into Catherine suddenly and spun around but there was nothing in her face but concern. 'Master Ciel?' She called gently, going to her knees, her hand poised on her chest. 'My deepest apologies, if I had known, I would have made sure…'

'Is that how it's done? Sebastian is going to…' Ciel started, his eyes wide open, his contract seal glowing brightly. Catherine cut him off by standing up and guiding him back into his room by his shoulders. She placed him on the bed lightly, making him lie down.

She smiled gently. 'My brother is not me and you have a contract with him. It will not be like what just happened.' She reassured gently, pulling the covers over the young heir. His eyes were still fearful but not of her, even if the moonlight was casting an eerie light on her blood-splattered face.

'But…'

She hushed him and sat in a chair by the bed. 'I promise by my contract, my lady and I will keep you safe.'

'But how…'

'Leave it to me.' She stopped him again. And she bent over to place a kind kiss on his forehead as if she was looking after an ordinary child. 'Have no worries. Sleep.'

He closed his eyes obediently and Catherine sang the demonic lullaby that she used to sing for her brother as children. Ciel believed her words and fell asleep easily. When she exited the room, she saw her brother's smiling face. 'I haven't heard that in a while.' He commented, looking her over, her dress would have to be washed.

She smiled but apologized. 'I only sang it to calm him because he saw me eat a soul.'

Sebastian chuckled. 'I know. I've already cleaned up the mess on the lawn. Why don't you dress for bed? I'll have your dress cleaned by the time you awaken.' He said and almost laughed, seeing her yawn and smile. He was quite curious about how she planned to keep that promise when she would never take away a soul from him. Yet she hadn't lied.

'Alright.' She answered with a soft smile of her own. She leaned up and pecked her brother on the cheek. 'Good night, brother.'

'Good night.' He wished her well.
