Sawako Sekijou

Sawako Sekijou serves as the head of Ichinose Academy's Chemistry Club and consistently ranks second in science scores across the entire school, surpassed only by Rizu Ogata. Though she initially appears as a rival figure, her true feelings reveal a deep admiration and protective devotion toward Rizu. Rarely seen without her lab coat, she has a known habit of quietly shadowing Rizu around campus. Beyond her remarkable talent in chemical research, she frequently plays the role of a calm, observant bystander who subtly supports the romantic developments of the main cast.
