Sasori of the Red Sand has a little sister. Morrigan of the Red Sand. She had red hair like Sasori but she has blue eyes instead of brown. She got it from their mother while he got his eyes from their father. They both got their fathers hair. Morrigan isn't like her brother. She's not a puppeteer she's something completely different, something just as deadly maybe even more deadly than her brother.

This is going to be somewhat different from the show
