"Young Master?" Sebastian called, knocking at Ciel` s office door. "I have your afternoon tea."

Ciel looked up from his stack of paperwork. "Alright, bring it in, then." He said impatiently.

"For afternoon tea I`ve prepared a delicate vanilla madeleine," (It`s a shell-shaped French cake) "I hope it`s to your liking," Sebastian said, setting down the plate, along with a cup of cup of Ciel` s favourite tea, Earl Grey.

There was a sudden knock at the door.

"Young Master, were we expecting company today?" Sebastian asked.

"No," Ciel replied. "Sebastian, would you go and deal with that guest?"

"Yes, My Lord." Sebastian replied, bowing as he left.

Sebastian opened the door, revealing a scantily clad young girl, (Well, scantily clad for the Victorian era) with red eyes, cat ears, and hair every colour of the rainbow.

"Good afternoon, and welcome to the Phantomhive manor," Sebastian began.

"Like, hi!" The girl cooed cheerily. "I`m Princess Rainbow Sakura Star Michaelis!"

"Michaelis?" Sebastian said, confused. "I wasn`t aware we were related."

Princess pouted and stomped her foot like a little child. "No~, silly!" she whined. "See, I`m your wife! You love me because I`m a cat demon and you love cats, and I`m like, your super true love forever!" She threw her arms around Sebastian, but he pushed her away.

"My, you are most unsightly!" Sebastian shouted. "To show up here unannounced and claim such ridiculous things! Why would I take an interest in a silly little girl like yourself?!"

Princess started bawling. "Sebby-kun~" she wailed, "How could you be mean to your one true loooooove? No matter! I`m also the strongest demon ever, so I`m gonna like, kick your butt!" she shouted in resolve.

"If that`s really what you want," Sebastian sighed. "Young Master does ask that I entertain our guests."

Sebastian got out his signature weapon-cutlery, and threw a dinner knife in her direction. Princess ducked, and the knife missed.

"Ha ha, you missed!" She said childishly.

Princess jumped at Sebastian, but the highly athletic demon dodged her easily.

"No fair!" cried Princess as she hit the ground.

"Let`s make this quick," he said. "It`s getting close to dinner."

"You`ll never best me!" yelled Princess, "Because I`m the best ever!"

Sebastian threw two more dinner knives, Princess dodged one, but as she stopped to make another childish comment, the other hit her in the throat, killing her instantly.

Sebastian sighed and opened his pocket watch. "Goodness, it`s getting quite late," he mused, "I should start preparing Young Master`s dinner."
