Shattered Pieces (BB fanfic) CielxOc
The Sasaki twins have been raised by their doll making uncles their whole lives, following every order and command told by their uncles until the day Ciel Phantomhive began to notice the dolls sudden popularity and a photo of the Sasaki family, quickly deciding to propose a business deal with Charles and Ryan while Sebastian senses something off with the girls and then something lacking from the eldest. The Sasaki twins go on to their new lives at the Phantomhive estate while their past life fights against the new.
These pieces have become shattered, but will they be able to regain themselves and finish the game?
Also remember, the game is over if the king falls.
