Ookami, Sayuri

大神小百合

A suspicious third-year student who desires to make Shinobu exclusively hers. Ookami ranks first in her class and commands respect from her teachers and most underclassmen due to her exemplary conduct, yet she reveals herself as a calculated schemer in her pursuit of Shinobu. She tries to seduce Shinobu in an empty room but is repeatedly, albeit half-heartedly, rejected because Shinobu does not wish to hurt her. Her actual scheme was to provoke Momoko into losing her temper and getting expelled, thereby separating her from Shinobu. This plan comes to fruition when Momoko attacks her with a fire extinguisher. The incident is resolved quietly out of court, and although Momoko is permitted to remain, she opts to leave anyway. Although her plan ultimately succeeds, it proves futile as Momoko and Shinobu consummate their feelings several months later.
