Lina Inverse

When Hajime Kanzaka was in high school, he created a story where Lina was a 10-year-old clone of her now-older sister, Luna Inverse. In this story, Lina was obsessed with machinery. When Kanzaka began writing Slayers, he made Lina five years older and obsessed with magic instead of machines. Rui Araizumi claims that Lina's design was based on a young Audrey Hepburn.
