Ah, how Ciel hated that red-haired, loud pervert. She was a handful, Grell Sutcliff, a Grim Reaper who, for some unknown reason, was obsessed with his demon butler, Sebastian.

Ciel avoided her at all costs, having little to no patience when it came to her and her antics. However, he found himself in need for her services.

Ciel had ordered Sebastian to go get information for the new case the Queen Victoria wanted him to investigate. Consequently , Sebastian had to be away from Ciel for a while... and the kid didn't even know how to tie his shoelaces, let alone protect himself.

It was then that Sebastian gave Ciel a horrid suggestion: call Grell over and ask her to protect him, and oh boy did Ciel argue against said suggestion. But, eventually, they figured it was the only option.

Making a small deal with the Reaper, Ciel and her agreed that she'd protect him for a day, as long as she got to spend a day with Sebastian in return.

Well, the day were Sebastian was absent came, and by the morning, Grell entered the Phantomhive mansion in the weirdest way possible: by the window.

She sneaked inside the Earl's room , only to find him still asleep, and decided to wake him up herself...
