I would probably rate this closer to 2.5 stars if I could. I have enjoyed Vampire Knight for the past 3 years and have found it a compulsive read, even though the quality is somewhat erratic. The character styles have been steadily becoming prettier in a style I enjoy, but the art overall is lacking in the depth of detail the earlier volumes had and the creative angles that made the art interesting, looking a lot more mainstream these days.
Volume 11 includes chapters 49 to 53, chapter 49 continues from chapter 47, leaving chapter 48 as a bit of a filler chapter that doesn't quite fit in because it seems to lack in purpose and impact, a pity.
Chapter 49 introduces the new arc by skipping over a year, during which, flashbacks show, Yuuki refused to learn to use her fangs and has pretty much been starving most of the time while stuck inside for a whole year, Kaname has been working in the shadows gathering support for his rule and Zero and the hunters have been cleaning up after the chaos created by the destruction of the council. Kaname finally brings that in by signing a treaty with the hunters, but their relations don't seem to be as nice as they used to be, while Zero is included as the potential new president of the hunters, Yuuki is left out in the cold instead worrying about dresses and how to present herself at the party.
Yuuki falls flat in this volume, the concerns that once made her so interesting, with her hidden past, have all been revealed and she's left to dealing with more vacuous issues, such as the possibility of being in love with two men and her desires to support Kaname no matter what he does, she contributes pretty much nothing to the story but a bit of angst. There was a lot that could have been explored, such as the fears that kept her inside for a year, dealing with her parents and the reality of her past, angst over not seeing her friends and family for a year, all the changes, but any of that was just lip service and her plot boiled down to boy troubles while not really making any real decisions.
Yuuki's character is exemplar of this chapter, much of it seems to be about waiting for something to happen, waiting for a plot, though its intended to be a introduction to the new arc, not much comes of it, the drama is all built up to the reunion of Zero and Yuuki rather than any real drama and with very little comedy, this volume doesn't offer that much entertainment. Overall, volume 11 really lacks much impact.
