Incubus

The village of Nomen Tuum is introduced, famed for its healing water that can cure the sick and even beautify people. Outsiders flock to the village for cosmetic change, feeding its notoriety and temptation. The setting is described as a haven for darkness and demons.

Kia, a prominent succubus, grows bored with her routine of luring sinners. She longs for something more exciting than simple temptations. Amael warns that loving a pure soul could shatter their plans.

Kia begins to shadow Marc, a wounded soldier, and his sister Arndis, following them as they come to the sacred waters seeking healing. She disguises herself as a lost traveler to draw close. The siblings' movements set the stage for the seduction.

During a brief eclipse, Kia persuades Marc to accompany her to the sea, starting a dangerous bond. Arndis, meanwhile, is blinded by the strange light overhead and wanders in confusion. The episode marks the first moment Marc's heart leans toward Kia.

Marc and Kia's growing bond deepens as attraction flares between them. The affair unsettles the village's order and Arndis's plight adds tension to the siblings' mission. The sea's stillness becomes a turning point for all involved.

Marc insists that closer relations must wait for marriage, complicating Kia's scheming. He guides her toward the village cathedral, where stark images of Christ and the saints confront her. The sight unsettles Kia and foreshadows a clash between light and darkness.

Amael and Kia finalize their revenge plan and summon an incubus to torment Marc. The plan targets Arndis as well, and the incubus begins its attack on them in a secluded way.

The incubus assaults Arndis, fulfilling the sisters' plan, while Marc prays for his sister, making the sign of the cross as the demon closes in. The encounter shocks all and appears to seal Arndis's fate.

Marc fights to defend himself and his sister as the incubus nears him, and he appears to have killed the demon. Amael cruelly reminds him that he bears the sin of murder for the acts committed by the incubus.

Kia trails the dying Marc back to the cathedral and professes her love for him. The resurrected incubus interrupts and claims she belongs to the God of Darkness.

Kia defies the incubus and makes the sign of the cross, surprising even herself. The demon transforms into a goat and wrestles her to the ground as the struggle intensifies.

Kia proclaims she belongs to the God of Light and crawls toward Marc, embracing his love as the incubus is defeated by her choice. Their bond, though tested, remains fragile but hopeful.

The final scene shows the couple staring in disbelief at the boundary of the cathedral, with the goat-like incubus watching them from the gate. The image seals the tenuous balance between light and darkness as their future remains uncertain.
