The girls, learning that the next fragment is located in the Moon's orbit, are trained rigorously to prepare themselves to leave Earth. They also hear about a piano concert held by Hikaru's parents, who are trying to send piano music into space, much to the dismay of Hikaru herself, who barely gets to see them. Later, as the girls head for the Moon, they are once again interrupted by the cloaked boy, who ends up causing a blast. After having a dream, in which she laments to Subaru about not being able to listen to her father's song that she altered by herself, Hikaru awakes to hear the song being sent from Earth by her father, who believed a note she left that said she would be on the moon. After using the cloaked boy in order to catch the fragment, Hikaru manages to hear that her father kept the note she added to the song.
