Born from the weaponization of nuclear fusion technology, the superhuman weapons known as Defiers (D-fire) plunged the world into war—an apocalypse that wiped out 30% of humanity. The survivors came to loathe the Defiers, branding them the architects of extinction and calling them "Enders." Theo, the sole survivor among the Enders, lived for 30 years under the surveillance of the Ainex Alliance, his core removed, passing his days as an ordinary family man. But when the anti-nuclear terrorist organization "Zero Core" attacks, Theo loses his wife—and his daughter Louise vanishes without a trace. The peace he struggled to protect is shattered in an instant. Vowing revenge, Theo reawakens the forbidden power he sealed away three decades ago to reclaim his daughter. Standing against Zero Core's vast conspiracy and a world steeped in prejudice, the lonely battle of the last Ender begins. (Source: Naver, translated)
