As the synopis says, these four videos of 1:30~2 minutes each one were aired in theaters before the movie started. They were created to tell the viewers the basic rules of the theaters (don't smoke, be quiet when the movie starts, don't take pictures or video) while having a good time with the NisioIsiN 4koma art style and voice actors references (Madoka Magica x Monogatari Series) (Karen = Sayaka, Ougi = Mami, Hitagi = Homura, Hachikuji = Kyuubey). The OST of the shorts is the same they used in Nisemonogatari when previewing a new episode. Overall they were great introductions.
