Infiltration. Under the plan to expose Ikumi as a candidate for a beautiful girl contest hosted by the student council president, Kaori Shirakawa, Yuki and the others shoot a promotional video for the application. Emi, who is passionate about her artistry, begins to shoot a maniacal video in which Ikumi, who is wearing a worn-out shrine maiden outfit, is entwined with Rino's special slime, causing chaos. Ikumi manages to pass the second screening, and finally decides to infiltrate the student council president's office in order to find evidence of her wrongdoing.
