When high school girl Himari Takakura escapes the clutches of death thanks to a quirky spirit inhabiting a penguin hat, she gets a new lease on life—but there’s a catch. In order for her to stay alive, her twin brothers (with the help of three penguins) must track down a strange object called the PENGUINDRUM and in doing so, delve into the mysteries of their very existence.

The hunt for the Penguindrum is on! Kanba and Shoma are doing everything they can to track it down but how can they find something when they don't even know what it is?
