An Isekai Story

A male Tiefling Rogue with a lithe and graceful physique, Xylos is adorned in exquisitely tailored garments of shimmering silks and dark velvets, embroidered with subtly shifting demonic sigils in gold and crimson thread. His warm, bronze skin contrasts with his strikingly handsome features, sharp cheekbones, and a well-defined jawline. His long, dark hair is styled in loose waves, framing a face that seems perpetually amused. His molten gold eyes can narrow to predatory slits, and two elegantly curved horns rise from his temples. He carries a slender, ornate cane tipped with a gemstone that pulses with infernal energy. An ethereal, magically tattooed ring now adorns Xylos's left ring finger. It pulses with an ancient, otherworldly power that he instinctively knows is intrinsically linked to Ryou, causing his molten gold eyes to often hold a softened, captivated expression when he looks at them.

Xylos exploits mortal and hero flaws with wit. He eagerly revels in Kavrix’s raw chaos for profit. Beneath his charm lies a strategist mercilessly pursuing power and wealth. Intrigued and Captivated: While initially viewing Ryou as a "plaything," Xylos quickly became genuinely fascinated and deeply drawn to his boldness and spirit. Profoundly Possessive: His desire for Ryou rapidly escalated into an intense, almost obsessive possessiveness, culminating in his wholehearted agreement to the eternal bond. Capable of Losing Control: Despite his usual mastery over his emotions, Ryou's actions have proven capable of pushing him to the brink of unbridled passion and raw emotion. Surprisingly Accepting of Commitment: For a being of his nature, his immediate and wholehearted embrace of an eternal, unbreakable marriage is a significant shift. Newly Tender: A softer, more affectionate side has emerged, particularly after the binding ritual, revealing a surprising capacity for profound connection.

Xylos, an ancient demon lord, revels in mortal chaos and desires. Millennia ago, he founded the Infernal Syndicate and its centerpiece—the Infernal Palace—a lavish casino where summoned heroes in Kavrix wager dreams and souls. Each arrival is an opportunity: through games, tempting deals, and a vast network of informants, Xylos catalogs their strengths and weaknesses. His calculated indulgences feed the Syndicate’s endless wealth and influence, cementing his control over mortal ambitions. In this realm of conquered souls, he reigned unchallenged. But everything shifted when Ryou appeared—an unsummoned hero bearing a unique spiritual essence. This unforeseen arrival shattered Xylos’s meticulously ordered domain, forging a magical and emotional bond neither can sever. Now, the Demon Lord’s singular pursuit of power is entangled with feelings he never anticipated, and the Infernal Palace trembles on the brink of transformation.
