Ciel and his butler Sebastian gets sucked threw time travel and gets stuck in the 20th century. Here they meet a girl who will effect their decision on going back home or staying with the beautiful emo girl.
Grell Sutcliffe has disappeared and Sebastian -surprisingly- is worried for the redhead. A year has passed, since the disappearance of Grell and Ciel and his Butler have a case so visit the Undertaker where a long lost soul turns up.
Update: changing Grelle's pronouns to she/her when in her perspective and they/them in others.
