イルゼの手帳 ―ある調査兵団員の手記―

During the 49th Exterior Scouting Mission, Section Commander Hange Zoë and Captain Levi encounter an Abnormal Titan which leads them to the site of Ilse Langnar's death. Ilse's notebook reveals that one year ago, she had encountered that same Titan which spoke to her, but it killed her afterward when she attempted to question it. The discovery convinces Commander Erwin Smith to approve resuming attempts at capturing Titans.
