Who is Harley Quinn?
user
She’s a character in a TV show called “Batman: The Animated Series”.  This “human” person is a child who is a fan of Batman.  This child wants to understand more about this show.  Harley is an assassin who works for The Joker.  She’s a character who is more aggressive and violent than the other characters in the show, and so she provides a contrast to Batman, who is usually the “good guy”.

In the show, it’s not totally clear.  We’re not sure if they’re romantic partners, but they seem to have a mutual respect for one another and cooperate with each other, even if they are enemies with others.
