== Summary ==
As people are going about their everyday lives, they notice a Titan peeking its head through an archway. They stand there in disbelief, confused as to how a Titan can be there if Wall Maria is still intact. Chaos quickly ensues, as the Titan begins casually eating as many people as it can catch. A young boy, afraid and alone, hides in his home hoping the Titan will not find him. He notices it outside his window, and when it breaks through, he screams in terror before being eaten.
On the ground, people run in the opposite direction of the Titan; all except one woman, Elena. Though heavily pregnant, she stands with purpose and calls out to the Titan with complete respect. Slowly grinning; it leans down to her level, unfazed by her words, it quickly eats her. Afterward, it continues on its path of destruction. Due to the lack of technological advancements, humanity is incapable of adequately fighting back.
