Olivia is a moderately-sized Delcatty with large breasts. She can control the muscles of her throat, pussy, and ass to tighten or loosen them at will.
Olivia is from the same village where Mane was born. She moved to Sinnoh where she opened a cafe, and met Thomas, who she temporarily fell in love with. She later met Derek, who she is now dating. She is also best friends with Megan and Bryanna, the three of them being a sort of slut trio when Olivia was still in Hoenn.
