The residence is first shown in "Sad, Sad Santa", when Senbei Norimaki goes there to give his autograph to Midori while disguised a Santa Claus. It is next seen in "The Great Arale-Eye Caper: Part 2", when Senbei sends Arale Norimaki and Gatchan to Midori's apartment to have a bath, in order to see her naked via the Arale-Eye Caper. In the future, Taro Soramame and Tsururin Tsun are married and live in an apartment here.
