The Angel Demon Twins.

Job interview.

Rays of golden light peeked through the curtains and Maria decided it was time to wake up Rose and begin to get ready for the job interview. What? She's a demon so why should she need to sleep?
"Wake up Rose!"
"Nnnggg, five more minutes Marrie~ I'm tired~"
"No get up now!" Maria said. Rose continued to ignore her and huddled under the blankets like a baby. A smirk crept onto Maria's face as she got behind Rose and pushed her off.
"Aarrrggghhh!!"
"I told to get up!"
"Nnnnggggg-fine."

*Time skip to interview*
Maria and Rose knocked on the door to the young master's study and Sebastian opened it and showed them in.
"Welcome to the manor, I am the Earl Ciel Phantomhive and your master should you pass this little interview." A voice said. Maria and Rose looked to see a boy about the age of thirteen with slate blue hair and an ocean blue eye, the other one covered with an eyepatch. Maria and Rose stood there.
"We're going to be serving a little boy?!" Rose exclaimed.
"I would appreciate it if you held off the 'little' I'm perfectly capable for my age thank you very much." Ciel said, annoyance obvious in his voice.
"I apologise on behalf of my sister, I am Maria and this is Rose."
"Yes, well, let's get on with it!"
"Ok, first question," Sebastian began as he got out a clipboard and pen.
"Have you ever had any experience with working in such a big place?"
"Yes we both have, though Maria has more experience than I do." Rose answered.
"Any reason as to why Maria has more experience?"
"I would prefer if that was kept untold for now." Maria interrupted.
"Very well next question, which areas of common chores do you expertise in?"
"Washing and cooking for me," Rose said.
"And cleaning and gardening for me." Maria said.
"But we can really do anything you put us up to." They ended in unison.
"Ok.." Ciel said, a bit weirded out by their synchronised speech.
"Next question, do you know of any fighting techniques and are you masters at those techniques."
"We are both black belts in martial arts and I can wield a spear and dagger but Maria can wield almost anything, you just have to say the word and she'll wield it like a true expert."
"Interesting..." Sebastian said writing down all the information.
"It's not my fault I'm extremely talented." Maria chuckled.
"Thank you for the information ladies now comes the practical part of the interview, you will stay here for a further week and do normal chores and if the young lord is pleased with your performance then he will hire you."
"Okay."
"For now you two are to complete the week as how Sebastian said. You are dismissed." Ciel said. The two girls left and began to work around the manor, completing their tasks to absolute perfection and leaving the other three servants lost for words. Everything was fine until Sunday...
