5 - The other side of the other side of the other side would be the other side
The contest has finally begun but instead of a real contest to decide who’s the real Santa, Kagura, Otae and the five Santas together with Shinpachi and Hasegawa are shown in various scenes playing a role like a school girl and not fighting each other like in a real contest. In each scene they imagine, the Santa has to show his kind of version what he would do as Santa and this is judged by Kagura, Otae and Hasegawa. Although in the end none of the Santas has any desire to continue with this contest so they all quit. The episode ends with Kagura, all along figured out the identity of everyone, wishing everybody a Merry Christmas.
