Kuklo was cut alive from the corpse of a woman a Titan had eaten, and the people inside Wall Sheena branded him the Titan's son. Sold as a curiosity to the noble Inocencio household, he is freed by his owner's daughter Sharle Inocencio, who teaches him what the world outside his cage looks like. Determined to prove he is human, Kuklo sets out beyond the walls, a path that pulls him toward the Survey Corps and the first vertical maneuvering equipment. This prequel runs decades before the main Attack on Titan story.
