In this chapter, we learn that the battle is about to begin. The memory dust that lucia is trying to absorb is just a part of his plan to destroy the real world. He wants to destroy all the memories in the world so that he can destroy the parallel world. In other words, he wants to completely destroy the dimension in which the world exists. This is why lucia wants to wipe out all of the world's memories. He also wants to "drum up enough power" in order to destroy this dimension completely. This sounds good to haru, who is excited to meet his sister. He tells haru that he's so lucky that he has a family to return to. His parents died when he was young, and he became a dancer when he didn't have anything else to do. All of the memories of his childhood are flooding back, and haru can't believe how fast they're coming back. He's worried that something's up above them, and that they'll need more altitude to get to it. .
