Levi, Isabel and Furlan escape from the thugs, they start being persecuted by members of the Army. Levi guesses that they are part of the Survey Corps because they are way more skillful than the Military Police. Levi and his friends try to evade them by splitting them up, but his friends are finally trapped by two soldiers and Levi by Erwin Smith and Mike Zacharias. There Erwin makes a deal: if they join the Survey Corps, they will not be judged by the Military Police. Without other choice, Levi accepts the deal.
The chapter begins shortly after where the prologue left off with Levi, Furlan Church, and Isabel Magnolia being pursued by the Survey Corps in year 844, all of them utilizing vertical maneuvering equipment. The three delinquents skillfully maneuver their way through the Underground District, but the Survey Corps members are not so easily eluded.
Refusing to be caught, the three choose to split up, but, despite some complicated navigating by Levi, he is tracked down by Erwin Smith and Mike Zacharias, and the three engage in a brief brawl. During the struggle, Erwin manages to cut one of Levi's cables, preventing him from fleeing. Levi attempts to resist capture, but stands down upon seeing that Furlan and Isabel have already been apprehended.
With Levi and his allies restrained, Erwin questions them on where they obtained their vertical equipment, and how they became so skilled at using it. Levi remains defiantly silent, but after Mike roughly interrogates him, Isabel and Furlan reveal that they taught themselves. Impressed by Levi's ability and willpower, Erwin proposes a deal with him: if Levi were to join the Survey Corps, Erwin will not turn him and his companions over to the Military Police. Seeing that he is no position to refuse, Levi accepts.
