Keiko is of German, Irish and Japanese (her great-grandmother) ancestry. Born in Colorado, her family moved to Florida when she was five. She grew up to be a rebellious teenager, being kicked out of several public and private schools, and while surfing the Internet one day she came across a pictorial of porn actresses Jezebelle Bond and Jewel De'Nyle. That put the idea of getting into porn in her head. Later she acquired a boyfriend who worked in an adult-book store. Tired of dead-end jobs in stores and fast-food joints, she decided to take up stripping, and discovered her calling. After shooting a few adult films in Florida, she attended the porn industry convention called Internext and met several adult-film producers who encouraged her to go to California and break into the business, which is exactly what she did, and another porn star was born.
