"CHILLED TO THE BONE" Having finally found a way home, Hajime and his party head to the final Labyrinth--the Frost Caverns. There, in that frigid land, the party seeks out the last ancient magic they'll need to go back to earth. Upon entering the caverns a maze of ice and an ever-present sinister whispering chips away at their concentration. As they proceed through it, the party is split up. Separated from the others, Shizuku is forced to fight a copy of herself. Will she be able to overcome this trial and surpass her limits?
