But its fans have matured since then, and they've become more aware of the fan fic's glaring flaws, feeling that the cannibalism, dark elements, and boob jokes to be out of place in a fan series for a show aimed at little girls. Even the author herself admits, and agrees, that the fan series hasn't aged well and plans to rewrite it completely.
Germans Love David Hasselhoff: Apparently, the fic is famous around France. Not surprising, given that's where The Heroine and her family are from.
