Oh! Sûpâ Miruku-chan (1998)

Milk-chan is a five-year-old girl who lives with her outdated and frequently abused robot maid Tetsuko, and pet slug Hanage. Despite her age, she is constantly putting off paying her rent, saying politically incorrect things, and referencing Japanese pop-culture at random. She has also been recruited by the President to fight crime, which she does when she's not watching TV or eating snacks.
