The Last Phantomhive

What if Midoriya was not Hisashi's real last name and descended from the most feared and respected Earl of England?

Izumi Midoriya was an average girl who would face discrimination as Quirkless in Japan was seen as a disease.

So her father Hisashi, not wanting his only child to suffer, decided to take his family to England to be closer to his workplace. The current Queen of England made a no discrimination policy on heteromorph, animal, and 'villainous' quirks, and especially on the quirkless.

There, he tells Inko and Izumi that he is really a Grand Duke, and he only lied about his name to protect them. He came from the legendary Phantomhive Family, serving as the Queen's Guard Dog, and Voice of the People of England.

It was shocking to her that she was of
blueblood, but seeing that no one discriminated her, Izumi finally thought she could have a happy life.

But that was destroyed when Hisashi's jealous cousin, Lord Ikari, attacks the family mansion, resulting in the death of Hisashi and Inko.

However,
With the awakening of three demons, Sebastian, Claude, and Hannah, and one fallen angel, Ash, it also marks the birth of a Grand Duchess determined to erase Villainy.
