In a world ravaged by a mysterious curse known as the Shackle Spell, humanity is plagued by an otherworldly force that abducts the infected and replaces them with monstrous creatures known as the Defiled.
Levi, a young slum dweller, is among the afflicted. Deemed a hopeless case, he is prepared for the inevitable. Yet, Levi refuses to accept his fate.
With unyielding determination, Levi declares, "I shall survive and I shall break all shackles placed me, including the Shackle Spell itself." Thus begins his perilous journey to defy the odds and shatter the very fabric of the world.
