Flagon yells at Levi for wielding his blades the wrong way. Another soldier tries to compete with Levi as they train but fails because of Levi's speed.

Summary
The chapter begins with the Survey Corps staff in a meeting discussing Levi, Isabel and Furlan's entry into the military without training. Fragon complains that it is a breach of the rules but Erwin responds that this will be 'a key part of the reform'.

Commander Keith Shadis presents Levi, Furlan and Isabel as they introduce themselves and they are put under Flagon's command.

Flagon shows Levi, Furlan and Isabel to the barracks. Isabel gets excited at the thought of the three of them living together only to be disappointed by the fact that women lived seperately. Flagon explains to Levi, Furlan and Isabel that they are to have cleanliness and order much to the annoyance of Levi who was disgusted by the dirt on his fingers from running them along one of the beds' frames. Furlan promises that they'll keep clean and Flagon leaves commanding them to report to the training grounds once they wre finished unpacking. Furlan yells at Levi for picking a fight as Levi questions the barracks' cleanliness and retorts that he treated his Senior Officer the same way he treated him and that if he continued to treat him that way he would receive no salute. They then discuss a plan to steal some documents. Farlen advises that it would be best if they remain there quietly. Annoyed, Isabel asks if he thinks that she's stupid. Furlan asks her what 18 + 22 is and before she can give an answer by counting on her fingers Levi tells her that it's 40, calling her stupid and punching her on the head. Isabel says that everyone calls her stupid and Levi tells her not to talk nonsense, calling her stupid again, this time, ruffling her hair. Isabel then says that it was more important to fill your stomach than learn how to count underground as Levi pushes her head away. The conversation reverts back to the plan to steal the documents. Levi then declares that they would clean until not a speck of dust was present.

Isabel is seen using her Vertical Maneuvering Equipment with a horse much to a fellow soldiers shock. She talks about how Levi saved her underground and she became better as a person.

Furlan is then shown telling another soldier how Levi was their group's unspoken leader because they didn't want to burden him. The soldier then says that they have to get back to work because Erwin was watching them through a window. Inside the room, Erwin is told by an unknown person that it is time and he thanks them and says that he is going and puts an unknown envelope with a seal in his shirt and exits the room.

Flagon criticizes Levi for the way he holds his blades. One facing upward and the other, downwards allowing him to slice in a circle. Levi replies saying that he should let him do what he thinks is comfortable.

While training on makeshift titans, a soldier, in his thoughts refers to Levi and the others as idiots and that they know nothing about being a soldier. He and Levi slice a titan at the same time however, his cut not deep enough. In his thoughts, he curses at Levi, saying he won't accept defeat. He zooms ahead past Levi saying, out loud, that he would go on ahead. On another attempt to slice a titan he breaks one of his blades. Levi switches his blade around so that he could cut in his circular motion and cuts the makeshift titan so quickly that the soldier questions if it was from gripping the blade wrong. He then thinks to himself that Levi is inexperienced but has unquestionable strength. Flagon is then seen watching from a distance wondering if they should be accepted with open arms he then says out loud that he hopes nothing will happen, probably referring to the expedition coming up, as Furlan is seen sneaking into a room which looks similar to the one that Erwin was in earlier.
