To the Other Side of the Wall

is the 4th and final chapter of the 22nd volume and the 90th chapter overall of the Attack on Titan manga, written and illustrated by Hajime Isayama.

Overview
At the military meeting, officers of the Military Police Brigade mention the inevitable social chaos that will erupt if the truths of the basement become known, though Pixis believes spreading the truth is a necessity. Historia sides with Pixis, and the meeting concludes. Later, Hange and Levi speak with Roy and Peaure of the Berg Newspapers about the mixed public response to the new information. While Roy is proud of the Survey Corps' accomplishments, he is afraid of the implications the basement's information brings.

Later, Hitch meets with the 104th recruits in the Survey Corps and learns of Marlowe's death from Floch. He argues with the others about the decision to save Armin over Erwin, and the situation grows tense. Armin sides with Floch, but Eren insists that no one can know what would have been better and reminds Armin of the freedom they seek beyond Wall Maria. Shortly afterward, Historia hosts a ceremony for the survivors of the battle of Shiganshina District, and Eren sees a memory of his father in the Reiss Chapel when he touches Historia's hand.

That winter, the Titan guillotine was used to eliminate all the Titans in Wall Maria, confirmed in the last weeks of the season. By springtime, transport beyond Trost District was made possible through elevators along the Wall. Finally, one year after the battle of Trost District, Shiganshina was repopulated and the Survey Corps set out beyond Wall Maria for the first time in six years. Following the trail of a Titan dragging itself on the ground, they reach the borderline of Paradis and come to the ocean. As the others play in the water, Eren contemplates the freedom they will achieve when they kill their enemies across the sea.
