Summary: Catherine may be a witch and a demon but there are some things she's just not capable of. Undertaker shows her his job isn't as easy as that. She might not like it but that's what makes the shinigami man interesting, right?

Catherine had a very explosive nature. The kind that could not be contained for long. Like the fury of hell, it could be bottled up and kept but its release… is inevitable. Recently, she exploded. All over Undertaker. The shinigami was rather surprised but not displeased. He was actually quite amused but the man was greedy for humour and he saw a golden opportunity arise when Catherine belittled his occupation.

'Ah, my job can only be done by those of strong hearts. It's understandable that you would not take to it.' He murmured calmly, faking some slight anger. Of course, inside he was squirming with glee.

Catherine took the bait. Her cheeks flamed red. 'Excuse me?! I can do your ridiculous job a hundred times better than you can!' she protested strongly.

'Will you back up those words, my dear?' Undertaker asked her. His daring tone sent delicious shivers up her spine.

'Yes.'

PART TWO

So it was. Lizzie insisted on watching and being herself, she insisted that Ciel watched. The young earl feigned disinterest but he was curious himself and so dragged Sebastian along. The demon butler already knew what was going on. He had been the target of his sister's explosions long before this. He did however have the utmost confidence in her abilities. A demon witch against a shinigami. To him, it was obvious. As it turns out, not so much.

'First, we shall embalm the bodies.' Undertaker said smoothly, revealing two corpses, relatively fresh. Lizzie widened her eyes but merely scrunched up her face. Her apprenticeship with Catherine thought her when and where she was to be strong or be cute.

'Where did you acquire these bodies?' Ciel asked with narrowed eyes. Hopefully, he wouldn't have to arrest the shinigami for murder.

'Young Miss Sutcliffe had a little accident yesterday which I was called in to handle. It will not cause you inconvenience.' He promised Ciel with his usual smile. Sebastian's eyes darted quickly, looking for that ridiculously red creature.

Catherine smiled slyly. 'Worry not brother, I locked that annoying transvestite in a spell.' She assured. Sebastian smiled his thanks.

'Ready, my dear? Begin.' Undertaker said suddenly. He rushed to the body and began his work. Lizzie and Ciel watched as Undertaker's hands caressed the body with love and care even as he proceeded with the gory process of embalming the body. Sebastian was preoccupied with the anger on his sister's face.

A spell shot at Undertaker which he dodged with a giggle. 'Cheat!' She yelled but she flooded herself with spells as she said so, using one for speed, she embalmed the other body quickly to catch up to her lover. But her movements were professional and cold, nothing like the affectionate touches of Undertaker.

She finished her work, a second after he did and he announced the next task gleefully. 'Next one is simple, you watch me do it many times. We build them coffins.' Catherine was filled with competitive spirit. She actually tied with Undertaker, both with gorgeous elegant caskets, completed within the same second. Lizzie was absorbed in the competition, rooting for Catherine.

Ciel joined for the sake of his fiancée's enthusiasm, stating nonchalantly that Undertaker would win due to his years of experience and routine practice. The tasks went on with vigour but Catherine's anger did fade until only the competition was left in her system. She smiled at her young apprentice when Lizzie cheered openly at the cemetery for the last task. It was late afternoon and Sebastian was just serving tea with a small smile in place. It was a strange place indeed to serve tea for the young couple, especially in winter.

Lizzie was wrapped in furs and winter clothes as was Ciel but he felt nothing, actually enjoying the dreary weather. Lizzie's face lost some colour but she smiled all the same. It was only when she began to huff short breaths of fog that Ciel made her sit beside him to regain some of the warmth she had lost to her excitement. Catherine took a moment to prepare Lizzie a cup of hot vanilla, her favourite, before returning to the competition.

'We must dig the grave, the final task, my dear.' Undertaker said delightedly. It sounded quite deceptive and Catherine narrowed her eyes at him. They stuck their shovels into the ground. Undertaker's slid in with ease. Catherine's struck against the ground like metal.

'What?' She wondered discontent, striking the ground harder with a little more improvement. But Undertaker laughed freely.

'If you do it so very roughly, you'll break it, young witch.' He purred. Taking his shovel, he demonstrated his ease in the task. 'It must go in smoothly.' His seductive voice sounded slightly mocking to Catherine. Undertaker was having the time of his life, teasing her.

Catherine tried but she couldn't do it. Her grave was shallow and messy while his was neat and deep and done in less time too. Catherine huffed and stuck the shovel in the ground while Undertaker buried the bodies and finished up. The sun began to set, cast the shadows of the tombstones long. Catherine refrained from sulking. It was immature but then again, she was too by nature. Sebastian tried not to laugh at her. Lizzie congratulated her drive anyway, Ciel agreeing.

'You did well, my darling demon-witch. But I won.' He reminded her sliding his shovel beside hers and standing before her straight. 'Shall I have a prize?' He asked, his voice rolling rough and smooth together. Catherine met his green-yellow eyes with her red ones. His lips smirked.

She pulled him to her by his clothes and feasted on his mouth hungrily. Sebastian moved himself to block the children's view, Ciel enjoying his disgusted face while Lizzie squealed. Undertaker let loose for a moment, allowing his arms to demand their bodies' contact. When she pulled back, she was twisting his braid around her finger, a pleased look on her face mirroring his own. There was a devilish smug smile on his lips.

'Fine, next week.' Catherine agreed. The other three looked in surprise, having thought that the searing kiss that Catherine instigated was the prize itself. 'You may dress me as you please.' She said with a smile, as if indulging a little boy's whims.

'That kiss wasn't the prize?' Lizzie questioned, confused. Ciel also raised a brow. Sebastian merely sighed. Catherine looked at them and grinned.

'No, that was for my own enjoyment. Besides, he steals those on his own anyway. Regularly.' She commented, looking proud at the look her brother gave her but she beamed at Ciel and Lizzie with true pleasure. 'Isn't he just so very interesting though? Unpredictable as can be!' Undertaker giggled at the compliment.

Sebastian softened at his little sister's words. That was exactly the kind of consort that Catherine would accept, no other. It seemed she has finally found a worthy candidate to be her mate. Even if it was a shinigami.
