Fang and the gang return in this all-new Tactical RPG, directly connected to the story of Fairy Fencer F™: Advent Dark Force.
Fang and the others run into a mysterious woman named Glace, who has the ability to brainwash other people with her song. Another woman named Fleur joins their party, who also has the power of song. The two are known as Muses, and are able to boost or change other peoples’ abilities with the power of singing. ​
What could Glace’s motives be?​
