While this is a continuation of the first Jigoku Shoujo, it is quite different. For one, the main character from the last season isn't here (not really surprising), and the story is told predominantly from Jigoku Shoujo's point of view. Two, the authors were obviously annoyed with the one-story-per-episode format from before, so... they kept it, and toyed and played with it (very successfully, I might add). Three, this series is noticeably darker that the previous, and if the previous depressing stories mostly ended in happy endings (of sorts), then these ones don't always follow that rule. This is pretty much everything you need to know about Futakomori
