Konoe Ayatsuki Mercury

Konoe A. Mercury, more commonly known as Nine, was a witch and one of the Six Heroes.

Information
Konoe was an attractive Witch whom went by the name of Nine. She had long, pink hair and dresses like a stereotypical witch. The name "Nine" comes from her being the ninth member of the Magic Guild's Ten Sages. Caelica A. Mercury is her sister, Shuuichirou Ayatsuki is her father, and her mother is deceased; she is the mother of Kokonoe. Nine's role in the story is further explained in the novel, BlazBlue: Phase 0. She tells Ragna to beware of Terumi.

She passed down her knowledge of magic to mankind during the Dark War. During the Dark War, she created the Nox Nyctores in order to help humans fight against the Black Beast. After the war, she discovered what Terumi's future plans were, and he killed her (this action is why Kokonoe despises Terumi). She created the Nox Nyctores using human transmutation, a process that requires thousands of human souls. Due to similarities in their appearance and abilities, Phantom may have some connection to Nine. It is notable that in Lambda's arcade mode, Hazama tells Kokonoe that the magical power he used to create Mu belongs to Nine.
