Spring 854. Marley is calling up inexperienced recruits from all corners of the empire to the eastern border in order to put an end to this four-year war against the Middle Eastern alliance, which is beginning to take a heavy toll. On the other side of the continent, a small group from Paradis Island is traveling to the mainland for the first time after a century of isolation... But their only deterrent, Eren Jeager, vanishes without a trace. As the Survey Corps prepares for the imminent last battle, Logan has no choice but to put the shadows of his past aside if he wants to spare as many lives as possible. He embarks on a race against time to slow down the unstoppable machine of total war, even if it means being crushed in its gears.
