This volume focused on Aqua during her time in the Realm of Darkness. It follows most of the events of the 0.2 game. King Mickey explains to Riku and Kairi about the last time he ran into Aqua. Shiro's artwork beautifully displays all of the suffering Aqua endured while being trapped in that world. Her bond with Terra and Ventus is what keeps her fighting. Now it's up to Riku and King Mickey to rescue her.
