Attack on Titan: Wings of Freedom

After fierce fighting, the Trost District is back under the control of the wall's defenders, and Eren Yeager's newly discovered ability to transform becomes the subject of close scrutiny by the military leadership. He is placed under the responsibility of Captain Levi Ackerman, who leads an elite squad of the Survey Corps that operates beyond the fortifications and carries out especially difficult missions. The squad keeps the new recruit under guard, restricting his movements and monitoring every attempt to use his transformation, since the instability of his power poses a danger to those around him.

Training begins with testing his response to orders, studying the conditions that trigger the transformation, observing how long he can hold the form and recording his behavior after he returns to human shape. The squad makes sorties beyond the walls to test the use of this new power against individual targets and to assess how effectively he can work with the other soldiers. During these operations, the soldiers are forced to change tactics quickly, as the giants' behavior differs from previously recorded patterns, and their unpredictable movements demand precise coordination from the entire group.
