From these gates emerged not only deadly threats but also new races and advanced technologies, forever altering the fabric of human civilization. Kang Hyun-jun, a man who once lived in a mundane, struggle-filled life, awakens in a parallel world after a fatal accident. Gifted with a mysterious "Player System," he discovers he has the ability to grow stronger by hunting monsters and exploring the treacherous portals. But in this new life, nothing comes easy. As he battles both external enemies and the internal struggles of adapting to a perfect family he never had, Hyun-jun must navigate a world steeped in corruption, inequality, and alliances forged between humans and otherworldly beings. Through perilous dungeon raids, evolving monsters, and escalating political conflicts, Hyun-jun rises from a lowly adventurer to a pivotal force in the battle for humanity's survival. As the portals grow stronger and the creatures within more intelligent, Hyun-jun must face the question: can one man bridge the gap between worlds, or will the gates' power consume everything? Packed with thrilling battles, intricate political intrigue, and a deep exploration of human resilience, "The Limits of the Gates" weaves a tale of personal growth, sacrifice, and the relentless fight against the darkness threatening to engulf two worlds.

After years of war, triggered by the tragedy caused by the appearance of towers and portals to other dimensions, the different races finally live in peace, prosperity, and happiness… except for the undead and the demons. They don't count; after all, they were the losers. Thus, their fate was sealed: marginalized beings, condemned to slavery and banished to desolate and inhospitable wastelands. The same as always. The heroes received fame and fortune for defeating the alien demon god, and Lyon, well, at least he is in good health. However, secretly excluded for practicing dark magic similar to that of demons, for his questionable taste in dark matters, and for admiring necromancers, he was soon deliberately forgotten by everyone. And if that weren't enough, his friends ended up killing him. “I’m sorry, your presence makes us nervous,” with some random excuse, they threw him into the abyss of the dead in the last SSS portal before completing it and sealing it forever. What no one expected was that Lyon would awaken a unique stigma: the Tamer of Death. He would take control of the portal, create his own tower, start adopting homeless losers, and join the games of destruction and calamity, also known to humans as the day of the apocalypse... Not even Lyon expected it... He just wanted to return to his former, beloved NEET life! Can't losers live too?
