Sengoku Heat I: The Ghost and the Demon King

In 2026, Soma Kurogane built skyscrapers. In 1559, he has to engineer his own survival against the Demon King. Soma Kurogane is a brilliant 24-year-old structural engineer, a young genius who accelerated his education and career at an early age and whose life is defined by cold logic, strict corporate hierarchies, and flawless mathematics. But when a devastating car accident plunges his SUV into the freezing Kiso River, Soma was rescued by a mysterious figure and wakes up four centuries in the past. Stranded in the blood-soaked Sengoku period with nothing but his wits and a single waterproof suitcase of modern tech, Soma is captured by Japan’s most terrifying warlord: Oda Nobunaga. To avoid execution, Soma must prove his worth. Armed with 21st-century logistics, he treats the brutal feudal era like a hostile corporate takeover. From standardizing matchlock infantry to constructing impenetrable geometric palisades, Soma uses his unyielding composure to navigate the deadly politics of the Oda vanguard. But his flawless math cannot calculate the heavy, suffocating gravity of the Demon King. Nobunaga doesn't just want the engineer's mind; he demands absolute, territorial possession over Soma's body and soul. The Warlord becomes intensely, dangerously fixated on his new asset, relentlessly weaponizing his physical dominance to break Soma's sterile boundaries. Caught in a highly charged, suffocating game of power, submission, and biology, Soma's cold logic begins to melt under the Warlord's blistering heat. As enemy spies infiltrate the mud and assassination plots loom in the dark, Soma must balance the crushing weight of a warlord's obsession with the treacherous desires of his own captive flesh. In Sengoku Heat I, you will be introduced to the possessive advances of Nobunaga, and the unyielding mind of Soma. The math is absolute, but the foundation is built on blood. 🔞 Content Warning: Explicit MM Erotica, Dark Romance, Reverse Harem & Love Triangle Dynamics.
