Overview: Many years before becoming the famed captain of the Survey Corps, a young Levi struggles to survive in the capital's garbage dump, the Underground. As the boss of his own criminal operation, Levi attempts to get by with meager earnings while aided by fellow criminals, Isabel Magnolia and Farlan Church. With little hope for the future, Levi accepts a deal from the anti-expedition faction leader Nicholas Lobov, who promises the trio citizenship aboveground if they are able to successfully assassinate Erwin Smith, a squad leader of the Survey Corps.
