All Purpose Cultural Cat Girl Nuku Nuku Dash! - S01

It's the not too distant future. One day Nuku-Nuku showed up and started living with the Natsume family. She had lost her memory, so she took on the identity of a beautiful girl named Atsuko Higuchi. She was so beautiful and gentle, and on top of that, such a great cook that Ryunosuke, 14, was all smiles. But after she came to town, a series of mysterious incidents began happening in Maneki City: experimental machines going haywire, roaring fighter aircraft flying low, mass destruction in the city. In every case, a mysterious girl was spotted at the scene.
