The ones harassing Riko and her friends were "former" student council president Enomoto Yuiko (Eno), whose work was stolen by Maki, and her friend and student council treasurer Mizushima Sayori (Sayo). Declaring war on Riko and her friends, Eno and Sayo sneak into the student council room where they discover materials related to the love lab.
