Laplace no Ma is Shirosaki in the appearance of a white rabbit in a tuxedo and a top hat with human mannerisms. He is neither sinister nor kind, and has a tendency to speak in riddles. His brief appearances in the N-Field leave the Rozen Maiden with nothing more than poetic and seemingly nonsensical advice. Despite the fact that he was seen supporting Barasuishou (and later, Kirakishou), Shirosaki's true motives remain a mystery. His rabbit form is named for Laplace's demon. Featured in the manga and the second season of the anime. He also appears at the end of the OVA.<br /><br />
