(Demon Instinct. Final and English Ver) First book of Demon Instinct. For centuries, the Kingdom of Silveria stood unmatched-its power unrivaled, its lineage blessed by the divine. But all of that ended when Kohaku III, the strongest warrior of his era, perished in battle. His death signified not just the fall of Silveria's noble bloodline but the start of an era where its enemies thrived in his absence. At least, that's what the world believes. In truth, Kohaku III-once known as The Walking Catastrophe of Silveria did not perish. He survived, hidden in the shadows, changed his name, and trying to abandon his past. Now, under the alias Kouna, he lives in obscurity, far from the battlefield, hoping for a life of quiet anonymity.

Second book of Demon Instinct. A grand mansion stands in the middle of the desert, untouched by time. It is golden, endless, and waiting. The air is warm. The food is rich. Perhaps somewhere in this mansion, somewhere beyond the golden halls, something is watching. No door is truly locked. But the deeper you go, the harder it is to leave. And beneath it all, something is waiting.
