Nomenclature and Etymology
Shakoukai means "high society" (社交界) in Japanese. "Shakoukai" also sounds like the Japanese word for giant clam, (シャコガイ, shakogai) making her name a pun. This is the reason she appears covered in clam shells and keeps a dignified, polite attitude, even in youma-form.
She had the appearance of a purple-skinned woman covered and clothed in yellow seashells
Kunzite transformed Countess Rose, an English aristocrat who ran the Princess Seminar, into Shakoukai. She planned to determine who Sailor Moon was by seeing that a girl was clumsy at everything else except frisbee, relating to Sailor Moon's Moon Tiara Action attack. During the last class, all of the girls' passed, except Usagi, Rei, and Minako, who failed at being able to ballroom dance. She greeted the girls who did pass, including Makoto and Ami, and encased them in wax. Shakoukai then emerges from the other room, declaring that Usagi, Rei, or Minako must be Sailor Moon.
The girls can avoid being encased in wax and transform, but their attacks prove to be useless against the Youma. But, when Tuxedo Mask and Kunzite show up and begin directing differing orders to Shakoukai, she becomes confused about who to listen to. Sailor Moon takes advantage of the situation and defeats Shakoukai, reversing the effects of the Youma's powers and transforming her back into Countess Rose.
Shakoukai could encase people in green wax, turning them into wax figures by spraying wax at them.
- Shakoukai is among the youma that appear in Pretty Soldier Sailor Moon: Another Story.
