From Mortal to Underworld Lord

Carlen, an LA barista, hides as a demigod son of Hades sealed by a bracelet. Seeking his destined kiss, he visits House of Ironblade, faces Isolde—the heiress he once shared a night with—and unleashes power against Naga, saving the manor. When Sebastian betrays the family to Phorcys, Carlen slays the sea god but goes berserk until Isolde's kiss breaks the curse. With Sebastian exposed and Hades surrendering to Zeus, Carlen inherits the Underworld throne.
