RUI SAIONJI:
ANIME

Rui Saionji is a famous tennis player who is a student at Juuban Junior High School. She appears only in
episode 014.
She is very close friends with
Naru Osaka;
her mother is a long-time patron of Naru's mother's store
Jewelry Osa-P.
The two have known each other since they were very young girls, and although Rui is only one year older than Naru, Naru
calls her "big sister."
Nephrite used
Rui as his first target for energy. He appeared at her tennis practice one day, disguised as a tennis coach named
Masato Sanjoin. He used the opportunity to put his evil crest on Rui's racket, causing her to reach her peak energy very
quickly. Not only did she begin working harder and getting better, but her personality changed for the worse. This worried
her friend Naru, who was unable to even talk to Rui. Eventually, her energy peaked and the youma
Tesunii emerged from her
racket. After Tesunii was defeated, Rui's personality shifted back to normal, as did her friendship with Naru. Rui had no
memory of anything that happened.
