Spoiler for speculation based on ep. 10:

The way Matsuri said "fade away with me." sounded closer to performing suicide together instead of running away. It doesn't leave out the possibility of them eloping somewhere else, but if so, based on what I know about Japanese and Korean culture, she would be more likely to say something like finding something new or seeking freedom.

Aono used a interesting line to describe herself: Sacrificial Lamb. Perhaps she was supposed to be given up as food for a monster(vampire), but she was kept alive with help of Yorito, thus her unusual attachment to him, and relieved of loneliness by Matsuri. That may be why Aono is especially nice to Koyori who seems to be able to share and relieve her of her loneliness.

As many noted, interesting choice of angle for Mana. That scene was aimed right at doujinshi makers.

The speculations most popular in Korea is that Matsuri wants to know how the sword may turn a Yaka back into normal human being. She is tired of the life, and feels that she indeed is the source of misery of many. She also seems to believe Aono should find her own life without Yorito, which is true, and for this reason and that Yorito will not be able to become a normal adult would mean he would go through same suffering she went through for what seems like eternity, she feels it is best if Yorito disappears with her. The sword would be a way to give back a normal life to at least one Yaka, which I believe to be Mayuko, since she is the one most likely to be able to resume normal life among three Yakas. I think she will learn of the sword's power and offer the sword's power and her life to Aono. She will probably let Aono choose who will become normal, Aono or Mayuko. Now the interesting twist may be Aono may choose to end her life, she already performed suicide once, instead of Matsuri.

Lastly, I wonder if the hand we see in the opening song, touching the album with Matsuri's picture is actually Koyori's hand. It doesn't look like Yorito's and the pajama seems too cute for Mana or other older girls.
