Attack on Titan: Doomsday Bunker

The apocalypse descends, and Cheng Feng pays with his lifespan to shelter humanity in a bunker for thirty years. But after three decades, he is betrayed by his adopted daughter Cheng Xin and the ambitious Lu Wenjie—the two forge fake recordings of life on the surface, deceive and incite the people, and send Cheng Feng to the gallows. The masses swallow the lies, blow up the bunker, and rush toward the beautiful oasis above—only to step straight into a captivity trap set by the Titans and Lu Wenjie. When the Titans reveal their true faces and begin the slaughter, the people are consumed with regret. Cheng Feng, who mastered mecha technology long ago, must decide: will he set aside his bitterness and save humanity once more?
