Nine the Phantom

Nine the Phantom, born Konoe Ayatsuki Mercury and historically known as the Great Magister Nine, was one of the Six Heroes, the creator of Ars Magus, the Nox Nyctores and a hailed figure across the world. She was the older sister of Celica A. Mercury, wife to Jubei and mother of Kokonoe. Nine was known for her incredible talent with both magic and sorcery which she used in great efforts to keep her family safe. Nine sacrificed herself to stop Izanami from destroying the world in Doomsday.

Nine is one of the main protagonists of XBlaze Lost: Memories and first appeared as Phantom in BlazBlue: Continuum Shift. Nine was finally made playable in BlazBlue: Central Fiction where she is the final boss of Arcade's Act I.

Central Fiction
Nine entered the embryo, keeping her memories and free of Izanami's contract. She absolved to finally bring about her new world and to stop Izanami at all costs. In there, she found Carl Clover and began mocking him over his father. She told him that Relius was partially responsible for the beginning of the Dark War She began using the Phantom Field as a base of operations, specifically Purgatorium. At some point, she created multiple illusions to taunt Hakumen over the Dark War Eventually, she summoned Ragna, and the two battled. She won, and told him to defeat Izanami as she had to the chosen, and used phenomenon intervention to send him back to Embryo.

Using phenomenon intervention, she teleported all the chosen to the Embryo’s version of Ikaruga and emitted a voice telling them to defeat Izanami and claim their piece of the Azure. She found Relius, and they talked about the Nox’s and how to remove the Tsukuyomi Unit from guarding Amaterasu. Nine claimed that by retrieving the other Nox’s, she can remove their cores and make Take-Mikazuchi even more powerful than before. She later found Nu-13 attempting to retrieve the Rettenjou from Bang Shishigami and interrupted their fight, making it a three-way battle. Unfortunately for her, Bang managed to flee with his Nox and its core. She used the Requiem to constantly move Ragna through possibilities.

Later, Nine found a group consisting of Jubei, Iron Tager, Kokonoe, Jin, Ragna, Celica, Rachel, and Trinity entering her workshop. She fought Jubei, who was standing guard, defeated him, and threw him into the group. She explained that she was going to end the world, with Requiem becoming its replacement God. She told the group of the Dark War, and during its aftermath, how it should have been impossible to create Ars Magus in such a short space of time. She then told them of the Prime Field War and how the world as they know it came to exist before finally fighting Ragna – the battle was going her way for a great portion of it, but Nine was distracted by looking at Celica, which bought the Grim Reaper enough time to gravely wound her and steal her dream. Jubei and Celica rushed to her side, and she promised them that she would meet them in the afterlife.

Izanami came to her workshop, making Nine use the Radiance of Extinguishment, allowing her to both activate Requiem and bind Izanami. Nu entered, and was stopped by Jubei, who rushed to her side to protect his wife. Nine gave Ragna a warning that they would have one week until the space-time around the workshop would return to normal. She died, dissolving into seithr – her last moments spent being happy that Jubei could protect her one last time.

''Nine's temporary form after she was sealed by Terumi in the Boundary... upon the Black Beast's defeat. Why she stays by the Imperator's side and does her bidding is unknown.''

Nine
Celica's older sister, and one of the Six Heroes.

''She taught magic to the world, and helped develop its scientific hybrid, Ars Magus. Jubei is her husband, and between them, they have one very strong and powerful daughter: Kokonoe.''

''Like her belligerent personality, her magic is quite offensive and aggressive in its nature. She is determined in her ways, and loves her sister, which can sometime result in extremely reckless behavior. Her coffee's texture is said to change by the amount of sugar she puts in it. She also loves cats.''

''She can magic in its most pure form, which does not require the use of seithr. During the Dark War, she was admitted into the Mage's Guild as one of the Ten Sages at a very young age - a genius at her craft. She developed the Causality Weapons, Nox Nyctores, and led mankind to victory during the Dark War.''

After the Dark War came to a close, she was killed by Terumi for 'knowing too much.' As of 2200AD, she been seen doing the Imperator's bidding as the mysterious figure, Phantom.
