In this chapter, we learn that sumika is able to see the world through the projection of her sister's body. In other words, she can see what's going on in the world around her, even though she's not actually there. She's just imagining what it's like to be alive, and she wants to be able to show her sister everything. She wants to know what it was like to have sex with her sister, and how it felt to be brought to life again after her death. She doesn't want to know why she was forced to take back her present, and why she wanted to try to get back at the beta for raping her. She knows that she was responsible for marimochan's death, but she still wants to see her sister.
