Attack on Titan: No Regrets

A street‑kid’s deadly contract thrusts him into the Survey Corps, where destiny and betrayal clash.

Long before he earned the legend of humanity's fiercest soldier, Levi Ackerman scraped a living in the squalid depths of the Underground, the city’s hidden landfill. He runs a tiny gang of street‑wise outcasts—Isabel Magnolia, a sharp‑tongued pickpocket, and Farlan Church, a bruised brawler—who ekes out a meager profit by hustling scraps and contraband. When Nicholas Lobov, a charismatic agitator opposed to the Survey Corps’ expedition, offers them a chance at surface citizenship in exchange for assassinating the famed squad leader Erwin Smith, Levi sees a sliver of hope and takes the contract. The mission forces Levi into Erwin’s orbit, and the Survey commander quickly spots the raw talent and feral instinct that set Levi apart. Instead of a simple kill‑order, Erwin extends an unexpected invitation: join the 23rd Expedition and earn redemption, or be handed over to the Military Police to atone for his crimes. Torn between his grim past and a precarious future, Levi must decide whether to betray the man who recognizes his potential or seize the rare opportunity to rise above the darkness of the Underground. As the two worlds collide, the OVA explores how the promise of freedom can demand a price far steeper than any blade.

This two-episode prequel follows Levi's brutal upbringing in the Underground and his coercion into the Survey Corps, featuring the franchise's signature gory Titan battles and sudden character deaths. The story centers on trauma, betrayal, and the moral cost of survival, making it emotionally heavy despite its short runtime.
