At the start of Misaka Mikoto and Shokuhou Misaki's first year at Tokiwadai Middle School, Sha was in her second year and leader of one of Tokiwadai's 'big three' cliques. Said to be the closest to the title of "Majesty" at the time, her clique was the largest.

Sha and her clique believed that the gifted had a duty to do volunteer work (such as buying and greening deserts) and its members were dedicated to service, earning them popularity and power. It was suggested that their efforts might have been to thank for Tokiwadai being considered one of the top five schools. It was also suggested that the secret to Sha's popularity might have been the protective desire inspired by her weakness and frailty, having a weak constitution and being nicknamed the Infirmary Empress (保健室の女帝).
