Seventy years before the Colossal Titan breaches the gates of Shiganshina, humanity cowers behind the stone perimeters of Wall Maria, Wall Rose, and Wall Sina, utterly defenseless against the mindless giants roaming outside. When a fanatical religious cult opens a district gate to worship the monsters, an invading Titan wreaks havoc before vomiting a pile of half-digested human corpses. Among the gore lies a newborn boy miraculously alive. Branded the Titan's Son, Kuklo grows up chained in cages, beaten and exhibited as a freakish curiosity by corrupt merchant elites who blame his very existence for the disaster.

Determined to prove his humanity, Kuklo forms an alliance with Sharle Inocencio, the rebellious daughter of the noble household holding him captive. Escaping into the industrial underbelly of the walled kingdom, he connects with visionary weaponsmith Angel Aaltonen and the Survey Corps. Humanity lacks any tactical method to slay a Titan, having only crude harpoons, ground cannons, and sheer desperation. Kuklo volunteers as an experimental scout to test humanity's first gas-powered Vertical Maneuvering Equipment and hardened iron-bamboo steel blades, charting the bloody origin of every tactical weapon later wielded in the war for human survival.

What to Expect

This completed 17-volume military manga explores the grueling technological trial-and-error that created the Scout Regiment's mobility gear. Readers experience grounded, high-fatality battlefield encounters where scouts do not yet understand the Titan nape weakness. The narrative balances brutal survival skirmishes beyond the wall with cutthroat aristocratic corruption, underground black markets, and military tribunal trials inside the capital. Tension builds through engineering breakthroughs, daring field trials, and relentless physical risk rather than supernatural transformations.
