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.
