Kamuri seems confused upon seeing a photo of Eiko from middle school, as she looked different to the Eiko she saw a year ago. The girls eventually find that this alleged doppelganger is actually Eiko's younger sister, Miki. Kamuri reveals that she mistook Miki for Eiko a year ago, which led her to enroll at Hoshio Girls' School out of a desire to be with Eiko again.
