"The Nine-Tailed Vixen: Embracing Two Identities"

Prompt: write a part 2 were only keizoku and kurama and the only ones who remember her past life with even the other tailed beasts treating her as if she has always been this way. with kurama to help his new sister get adjusted slowly starts warping keizokus instincts and memories to reflect her new body. however she remembers she used to be a boy Inside Kurama, the towering Nine-Tailed Fox, a longing germinates. A longing for the companionship of siblings lost. As the waves of melancholy washed over him, he looked at Naruto in a new light, viewing him not just as his Jinchūriki, but as his sibling in solitude. A sibling that could possibly be reshaped into a more familiar form, a replica of his past, a vixen that would complete his world. A sudden determination took over Kurama. Naruto, hosting the fox, involuntarily started to transform into the desired vixen version of the Nine-Tails. Flashes of orange fur sprouted across his body, replacing his human skin, a new form began to take shape. A long and slender muzzle replaced his mouth. His legs contorted, taking the shape of a vixen’s digitigrade hind legs. Where there were once feet, now were fox paw pads, hindering any attempts to move his former toes. His voice, once boyish and strong, now altered into a feminine thunderous tone, similar to that of the tailed beasts. His human grunts and yells now echoed the fox's cries. A painful transformation rapidly altered Naruto's spine, contorting it into a quadruped stance, similar to Kurama's. Try as she might to stand on two legs, the new architecture of her spine simply would not permit it, forcing her to buck and stumble before giving way and forcing her into the humiliating experience, confined to all fours. Whereas Kurama enjoyed the sight of his new sister's struggle, Naruto was tormented by the inescapable imprisonment of her new form. Further down, her hands metamorphosed, becoming covered in striking orange fur as the nails grew into sharp, claw-like formations. They luxuriated within her slender, feminized fingers, ready for the hunt that was apt to come. A ripple went through Naruto's body as the nine tails, the Nine-Tails' namesake, sprouted from her lower back. Her previous human genitalia vanished, making way for reproduction organs befitting her new mammalian form, a biological function of motherhood on her new path. Her size adjusted, growing exponentially to match Kurama’s monstrous form, and her face pupated, an uncanny replication of a vixen's muzzle. Her ears too, pointed and upright, mimicked the nine-tailed beasts he was named after. With the transformation complete, Kurama bestowed upon his new sister a name, whispering it to her, etching it to her very core. "Keizoku", the Japanese word for 'continuing', for they were meant to continue together from this point on. Naruto's memories of her past life faded, his old name felt foreign, and the new name Keizoku rang true in his ears. Yet, the traces of his past as Naruto still lingered, he remembered being a male, striving and fighting in a human world. The world seemed to have altered its memories too, everyone but Naruto and Kurama had forgotten about Naruto's existence, and instead a nine-tailed she-fox now existed, a new identity known as the Nine-Tailed Vixen, or Keizoku. Even the surrounding tailed beasts seemed to recall her always being one of them, a female Biju.
