Torii, Eriko
Summary
Eriko Torii is Rei’s older sister and one of the most highly regarded members of the Yamayurikai. She is portrayed as a talented individual who excels at nearly everything, yet she remains an enigmatic and eccentric figure. Her rivalry with Sei traces back to their childhood, when Sei mocked her large forehead. Eriko once revealed that she chose Rei as her sister specifically to see if anything interesting would occur. She frequently clashes with Yoshino, who harbors jealousy toward the close bond between Eriko and Rei. Eriko has four older brothers and, after departing from Lillian, she pursued studies in Arts. She holds a particular hatred for dentists.
