Jordh, a goddess allied with her sister Fauna, confronts Kousuke over a dormant “devil’s seed” embedded within him—a force poised to awaken and devastate the world. Initially resolved to eliminate Kousuke, they relent when Fauna recognizes his inherent compassion, opting instead to purify the seed through vigilant oversight. Relocating into his home with their youngest sister, they implement a regimen blending physical and supernatural tactics to suppress the seed’s corruption, a collaborative effort Kousuke willingly accepts.

Their mission grows perilous as they clash with an Underworld emissary masquerading as Kousuke’s landlady, who schemes to trigger the seed’s catastrophic awakening. Jordh navigates the tension between her divine mandate to eradicate the threat and her empathy-driven resolve to protect Kousuke, steadfastly pursuing nonviolent resolutions even as dangers escalate.

Jordh’s appearance is marked by vivid blue hair, warm brown eyes, a stature of 1.68 meters, and measurements of 91-61-92.
