[DeepL Translation - needs review] Volume 1 Introduction: Inside the penguin house at the Uenohara Zoo, penguins were entertaining visitors with their cute movements. Then an announcement is made that the zoo is closing, and all the penguins who were performing earlier start to leave at once. Gimpei, who came to the zoo as a mid-career hire, suggests to the penguins that they rehearse every day to entertain the guests more. However, the penguins do not want to work after hours and go home.
