"Shadow Isles" is an original song featuring Xin Hua and is inspired by the online game League of Legends. Xin Hua sings as one of the monsters from the "Shadow Isles", describing how the visitor will never get off the island and outlining exactly what she will do with his or her death. This song, especially its PV, is reminiscent of a video game in which the hero battles through so many monsters, only to die at the end even though it seems the quest is over as he found the "princess".
