In this chapter, we learn that the fence is slowly falling down, and that the human body is able to move at high speeds due to the presence of the "spirits" . The only difference between the two of them is that they don't have the blood of the Yukawa family, so they're able to "decipher this world" and reap "some thing from it." They're the only ones in the world who can do this, and they can do it with the help of the human psyche.
