Isana is Yumeji's childhood friend, whom Yumeji has been living with for a while. Daughter of the cook of a restaurant in the city, she's a kind and quite shy girl who works with her father. Yumeji saved her as she was about to fall from a playground when she was young. She also commented once that she has a feeling that she had met Merry before but shook the idea off as her imagination. She's in love with Yumeji and asks Merry what kind of feelings she has for him. Her dream is to be an artist. When first seeing Merry, Isana speculates that Merry and Yumeji somehow resemble each other. After being targeted by Legion, Yumeji and Merry tell her the truth about dream demons.
