 is the prologue chapter of Attack on Titan: No Regrets, written by Gun Snark and illustrated by Hikaru Suruga.

Overview
Levi, Furlan and Isabel are watching the morning sky through an opening that communicates the surface with the Underground District. After that, they go for a walk on the District.

After the fight, he and his two friends escape with their Gear, all three being spotted by Erwin Smith.

Summary
The story begins with three friends, Levi, Furlan Church, and Isabel Magnolia gazing up at the morning sky through an opening in an underground sewer system. From the trenches of the Underground District, the companions spot birds flying freely in the sky above. Isabel wonders where they are headed, and Furlan states the birds are able to go wherever they please, unlike them. Isabel muses that she will join them someday as Levi announces they should get going.

The three purposefully make their way through the slums of the Underground District and are met with menacing stares from the city's unwashed inhabitants. Along the way, Levi accidentally collides shoulders with a man who responds angrily, though Levi ignores him and keeps walking. The man draws a gun on Levi, and Isabel suggests this situation might make for good warm-up. With that, Levi quickly turns around, revealing his Three Dimensional Maneuver Gear, and fires a cable into a barrel behind the armed man, bringing the barrels down on him. Before the man can react, Levi fires another cable into the ceiling above, launching himself into the air before taking the man down with a drop kick. Levi prepares to take down the man's friend, only to find that Isabel and Furlan, also sporting 3DMG, have already dispatched him. As the three make their getaway, Levi spots a soldier, Erwin Smith, watching them.
