Several decades before the fall of Wall Maria, a ferocious Titan enters into Shiganshina due to the actions of a fanatical cult. Chaos ensues, and from the consumed corpse of a pregnant woman, a boy named Kuklo is born. Shamed and disgraced for being a Titan's son, Kuklo faces hardships throughout his early life and is eventually purchased as a trophy for a noble family in Wall Sheena. There he meets Sharle Inocencio, a nobleman's daughter, who teaches him the history and ways of the people of the Walls.
