Bound to the "Corpse Friend" System — I'm the Only One Not Attacked by Zombies.

Silver, a quiet high school student who had long been involved in obscure private dealings to sustain his simple life, held a single warm wish in his ordinary days. He planned to pay a visit to his beloved adopted younger sister, his only kin and the sole comfort in his lonely world. However, an abrupt and unexplained dimensional shift tore through reality out of the blue, transporting him abruptly to a desolate parallel world entirely overrun by endless zombie hordes. In this terrifying alternate realm, global civilization has long crumbled, and helpless ordinary humans have been reduced to vulnerable fodder for ferocious wandering zombies, trapped in constant life-or-death peril. Amid the sweeping despair where all humanity struggled futilely to survive, Silver awakened a one-of-a-kind supernatural talent known as “Zombie Companion”. This unique ability rendered him completely undetectable and immune to all zombie attacks, making him the only human capable of moving freely and safely across the monster-infested wasteland. A naturally reclusive and introverted boy, Silver clung firmly to his only spiritual pillar—finding his remaining family in this chaotic world. Before setting off, he took in a helpless stray black dog, naming it Blackie, who became his first and only loyal companion in the desolate apocalypse. The pair embarked on a long and dangerous journey across ruined cities and barren wilderness, wandering through zombie-packed streets in search of his family. Having witnessed countless brutal scenes of zombie slaughter, Silver gradually realized that the dead monsters were far from the deadliest threat in this end times. As he encountered desperate, greedy and ruthless wandering survivors one after another, he came to understand the true cruelty of human nature hidden beneath the apocalyptic chaos. During a brief rest amid the ruins, Silver stroked Blackie’s fluffy fur and whispered a sobering truth into the silence. “Blackie, sometimes, compared to zombies, we should be more wary of humans…” Sensing the hidden dangers in the surrounding area, the vigilant black dog barked sharply in response. Panicked that the noise would draw nearby zombie hordes, Silver quickly hushed his companion softly. “Shh... Keep it down!” In this hopeless wasteland, the lonely boy and his loyal dog continue their arduous journey, learning to fear human greed far more than the mindless monsters lurking in every shadow.
