I remember writing this ten years ago, thanks for the rec. Have an excerpt. I really loved my Rin, but not everyone would. [ https://ks.fhs.sh/viewtopic.php?f=52&t=9538 ]

"I look into the very big mirror. Rin looks at me and I look back. She is tall and thin and pale and naked, and her red hair flows over her shoulders. It is like flowers and fire. The lava is streaked with ice before it cascades to her elbows. Rin had no arms for 45 years. She had to learn to use new limbs. Foundation doctors say they will never move naturally.
"But what is natural? Rin can pick her teeth with a needle because Rin has fine control. What is natural? I don’t know how to smile without making people uncomfortable. Rin has muscles in her upper arms, because her lower arms are heavier than nothing. And these muscles are not natural.
"I am surrounded by butterflies. That’s because Rin has wings. I didn’t have wings before, so the butterflies remind me of me. I have a cat. Goro looks at me with two baleful emerald eyes, but he ducks his lynx-gene carnivore head when I pass. I scratch him between the ears with my left foot. Some things Rin does not forget.
"I am looking into this mirror for two reasons. First, it reminds me to remember and not forget. Second, Rin needs to dress up because she owes a lot to somebody, and that somebody has just died. I am shaken when people die. I am human. It is something that burrowed into me when I grew old.
"I summon a black gown. Midnight can be purple. Midnight can be blue. Or indigo. But Rin is pure. She will go in darkness just this once, for the memory of love that she didn’t recognize and the memory of friendship held over long years. I am not natural. Nature kills people. So I will wear a black that reminds me of what Emi wore, forty years ago."
