Seventy-five years ago, a catastrophic event shattered the world’s balance, turning a third of humanity into skeletal beings called Setam. As nature collapsed elsewhere, humans survived by entering Setam territory for resources. Mustak, a silent 16-year-old, becomes a “Destroyer” by forming a contract with a Dragon and awakening immense power. Through brutal physical and psychological trials, he unlocks a unique near-invincible ability. After surviving deadly missions against Setam, he meets the mysterious warrior Tosif and undergoes harsh training. Facing Afzal in battle and uncovering dark truths, Mustak’s identity grows more enigmatic. In the end, he emerges as someone who not only wields extraordinary strength but also accepts death without fear.
