Une dangereuse stratégie de survie

The Penguin Spirit appears again and tells Shōma and Kamba to board a train and find a girl named Ringo Oginome who may possess the Penguindrum. With Ringo attending a girl's school, Shōma and Kamba send in their penguins to follow her. The brothers end up following her to a lingerie store, where they spot her maneuvering round the outside of a building in order to take a photo of something, which she shows to the brother's teacher, Mr. Tabuki. She then follows him home and hides out under his house, where the brothers conclude that she is a stalker, and pulls out a diary which allegedly fortells destined events.
