The battle to determine the fate of Tortus has finally begun. With Hajime and his companions deep inside the Sanctuary, the majority of those left defending the world from the army of apostles are just regular people. Despite their best efforts, the combined forces of the world continue to be pushed back—but just when it looks as though all hope is lost, Hajime’s final trump card kicks in. Meanwhile, Hajime himself faces off against Ehitruje, the self-styled god of this world. And in order to rescue his beloved vampire princess and return home, Hajime will need to transcend even the title of world’s strongest.
