The “D-fire” (Defier)—superhuman weapons born from the weaponization of nuclear fusion technology. The war they waged brought about a great catastrophe that annihilated 30% of humanity. The survivors came to despise the D-fires, calling them “Exterminators” or “Annihilators”)—the ones responsible for mankind’s near-extinction. Theo, the sole surviving Exterminator from the war, has lived for 30 years as an ordinary family man under the surveillance of the Einex Alliance, his core removed and his powers sealed. But when the anti-nuclear terrorist organization “Zero Core” attacks, killing his wife and causing his daughter Luis to disappear, the peaceful life he tried so hard to protect shatters into pieces. Swearing revenge, Theo unleashes his forbidden power for the first time in 30 years to retrieve his daughter. The lonely battle of the last Exterminator begins—against Zero Core’s massive conspiracy and the prejudice of the entire world.
