Etymology
Kitamatsu (北松) - composed from "Kita", which means north and "Matsu" which means pine tree or fir tree; making her name mean "North pine (tree)"

Rio (リオ) - originally spelled as "莉央", composed from "Ri", in this case meaning "white jasmine" and "o", meaning "center" here; so her first name means "white jasmine center"
