Defense Breaker

Jihun finds himself abruptly transported into Knight Defense, a demanding virtual world where survival depends on commanding the kingdom’s knights against relentless hordes of monsters. Tasked with leading humanity's last line of defense, he is expected to stand firm and protect the realm from annihilation. However, the heavy emotional scars and burdens he carries from his real life make this impossible to bear. Rather than embracing the role of a heroic commander, Jihun makes a radical choice. Overwhelmed by his past, he refuses to fight for a humanity he no longer believes in, turning his back on the very people he was summoned to protect. He abandons his post, fully expecting the game to punish his defiance or simply end. Instead, his betrayal triggers an unprecedented response from the system itself. Recognizing his rejection of the human faction, the game reveals a hidden route: the Monster Faction. The rules of engagement are instantly rewritten. No longer bound by the duty of shielding the kingdom, Jihun discards the concept of defense entirely. With a new allegiance and a dark purpose, he prepares to lead the monstrous horde, transforming the war into a devastating offensive campaign.
