Haruka Tsuchiya is an ordinary university student with a pet named Okojo-san, who was born in the mountains and brought to a pet shop before being sold. Despite their humble beginnings, Okojo-san managed to devise a plan to escape from the pet store and eventually found themselves living with Haruka. The two of them often experience amusing and bizarre events around them, whether it's people or animals they encounter. This is an anime that focuses on absurdity as its main theme.
