Dr. Mikeneko & Shironeko, along with their family members, return to challenge ChaCha and Seravy again. Most of the episode recaps their previous defeats at the hands of Magical Princess. However, they are disappointed when Seravy reveals that there is no reason to fight anymore due to the gates of Hell being sealed by Magical Princess's sacrifice. Fortunately, Seravy recommends the post of Curator of the Science Museum to Dr. Mikeneko, and he happily accepts.
