My re-write idea

I've decided to do a rewrite base on an anime/manga called Kuroshitsuji (Black Butler).

Basically, the original plot line is like this:
In a manor house on the outskirts of Victorian era London, butler Sebastian Michaelis serves Lord Earl Ciel Phantomhive, the orphaned twelve-year-old head of an English noble family and a toy and candy empire, who serves directly under the Queen as her "guard dog". Sebastian carries out any task required by his master while solving the problems plaguing England with ease and perfection, because of his demonic lineage and Faustian contract with his master. The parents of Master Phantomhive estate were murdered when Ciel was younger. As a result, he made a deal with a demon asking for vengeance upon those who had disgraced him, and the Phantomhive name, in exchange for his soul.

For the first part, I decided that I would like to write my story from Madame Red's Point of view.

Below is a brief description of Madame Red:

Madame Red, born Angelina Durless, was Ciel's aunt. As her title suggests, she was known for her red appearance and clothing. Initially she hated her red hair, which she inherited from her father, until Ciel's father, Vincent, said he liked it. Angelina fell in love with him, but became distraught when she found out her sister was marrying him. Madame Red later married Baron Barnett, who treated her lovingly and gently, stating that he does not mind that she harbors feelings for another. She obtained a medical license against the wishes of her parents and practiced at the Royal London Hospital. After a carriage accident in which her husband was killed, her womb and unborn child had to be removed. This causes her great strife as a doctor because she regularly performs abortions on prostitutes because they believe having a child was troublesome. Unable to bear her misery at ending so many pregnancies when she herself wants one so badly, she begins to kill her patients with Grell Sutcliffe and the two become known as Jack the Ripper. However, she cannot kill Ciel because she sees him as her own son. This causes Grell to turn on her and kill her.

For the second part, I'll write it from Grell's perspective, and the last part from Ciel's perspective.
Basically, three parts will be related to Madame Red.
