Arietta

Original title: いじめて、ください。アリエッタ

Directed by Akio Jissoji

A young widow becomes an SM call girl to pay off the debts accumulated by her yakuza husband. She's a depressed woman, merely going through the motions of existence, subjected to every cruel whim concocted by her clients. She's dedicated to the misery - even finding comfort in it - stumbling through life like a zombie.
