Seina is the only daughter and third child of Arata Yuki, a doctor, and Cori Yuki, members of the La Push Quileute Tribe, both head of the prestigious Yuki family. She is the younger sister of Jaden Yuki (by eleven months) and niece of Akemi Yuki, a traveling werewolf. Seina was born and raised in La Push Washington and was taught the ways of the tribe by her father. At some point in time, her family moved from La Push back to Forks, her mother's hometown.

Age age 16, she phased for the first time along with Jaden due to the appearances of vampires.
