Twin Sister of Alastor: A Gender Change, Body Change, Clothes Change Story

The sun shines on your face, reminding you of the promise a new day holds. You exhale softly, welcoming the warm sensation as you make your way through the city towards work. This is your world, the human world, one of cars honking, endless streams of people, and towering skyscrapers piercing the skyline. Suddenly, you freeze in place as a peculiar tune floods your ears, one that doesn't belong to this world. A nostalgic jingle that echoes from a vintage mahogany radio you hold dear at home yet strangely, is also unfamiliar. Your pace stumbles, eyes narrowing to seek out the source, when in front of you materializes a peculiar figure. Not human, not anyone you know. A suited demon, with features resembling a dear from the wildlife and a flair for the dramatics. He introduces himself as Alastor, the Radio Demon, from Hazbin Hotel. His phantasmal figure fills you with unease, but his charming grin compels you to a standstill as he tells you about his world, and his wish to have a sister, a twin. His words wrap around you like a gossamer veil, a reality you never solicited. As he draws a circle around you with a cane, your heart begins to flutter, your mind racing as an alien sensation floods your body. Powerless to resist, you yield to the forces at play, reshaping your existence against your consent. Your body feels strange, foreign as if it's rebuilding atom by atom. First, the gender begins to shift if you're male. The hard angles of your profile soften, your body developing subtle curves, your face becoming more feminine. It's a bizarre, unnerving revelation. Yet, paradoxically, it feels natural, like you've finally slipped into a suit meant for you. Your attire dances around you in a swirl of fabric, overhauling into that of a 1930s flapper-style dress, similar but not identical to Alastor's suit. In the blink of an eye, your world ages and decays, only to rebuild itself in hues of vibrant red, representing an era long forgotten, yet residing in your being as if you've lived through it. You take on Alastor's age and as you peak inside your reflection in the nearby glass pane, you see the spitting image of your new brother, female version. The crimson eyes, deer-like appearance, completed with a bow matching Alastor's bowtie. A gale of thoughts disorients your mind, memories that hold no trace in your past life fill your head, replacing pictures of your human existence one by one. First, your birthday, coinciding with Alastor's. You remember being born into the world of demons, but the memories don't terrify you, instead, they offer a nostalgic comfort. You remember growing up alongside Alastor, his protective tendencies, your shared mischief and endless laughter. The stringent reality casts a veil over your human life. Your personality morphs, mirroring Alastor's jovial and sadistic nature, yet holding onto the sisterly affection. As the transformation nears completion, an invisible barrier of assurance surrounds you, a promise of protection.... Alastor's protection. Flashes of your past life flicker and die against the blinding light of your new existence. As your memories recede, the parting strings of familiarity are severed, slipping away to an unreachable depth of your mind. As the journey concludes, your eyes flutter open, a bright glare dwindles against the haze of your red-toned vision. A beaming Alastor greets you, satisfaction dancing in his eyes, "Welcome home, sis!" he exclaims. Silence dances between you two before a smile spreads on your face, a familiar tune humming in the back of your mind. "It's good to be home." Your new reality unfolds before you, casting its vibrant allure. You can't remember the time when you were a regular human because you were always Alastor's twin sister...right?
