Chobits, Freya/Elda, the more loving one
Freya knows what sacrifice is. She made it for Daddy, because he loved Mommy more. She's making it again, because she loves Elda more. Her fingers, still agile as her systems shut down, slip between her sister's legs, delving into the place forbidden to them both.
The place that they should have come from, if life was fair.
Elda doesn't cry out as the fingers enter her, twirling deftly around the switch that gives and removes her life. She smiles at her sister, feeling something dark and bittersweet as she grasps Freya's free hand.
"I will," Elda says in answer to the probing fingers, and Freya smiles as her eyes close for the last time.
