"The Cosmopolitan Prayers" is a supernatural drama set in a world where ancient deities and modern society intersect. The narrative centers on Haruto Aizawa, a young man who inadvertently becomes the vessel for a forgotten god after discovering an ancient relic in his family’s shrine. This god, known as Amateru, is one of many deities who once ruled the world but were cast into obscurity as humanity turned away from faith. Haruto’s life takes a dramatic turn as he is thrust into a hidden world of divine politics, where gods vie for power and influence in the modern era.

The story unfolds across multiple cities, each representing a different cultural and spiritual backdrop, as Haruto and Amateru embark on a journey to restore balance between the divine and mortal realms. Along the way, they encounter other vessels—humans bonded to gods—who serve as both allies and adversaries. Among these are Yuna Shiraishi, a fierce warrior bound to the storm god Susanoo, and Riku Takahashi, a cunning strategist linked to the trickster deity Loki. These characters form a fragile alliance, united by their shared goal of preventing a catastrophic event known as the "Divine Collapse," which threatens to erase the boundaries between the human and divine worlds.

The plot delves into themes of faith, identity, and the consequences of humanity’s abandonment of spirituality. Haruto struggles with his dual role as both a human and a divine vessel, questioning whether his actions are driven by his own will or the influence of Amateru. Meanwhile, the gods themselves grapple with their fading relevance, torn between their desire to reclaim their former glory and their growing attachment to the humans who now carry their essence.

As the story progresses, tensions escalate between factions of gods who seek to dominate the modern world and those who advocate for coexistence with humanity. The narrative builds toward a climactic confrontation, where Haruto and his allies must confront the enigmatic "Eclipse Council," a group of ancient deities who orchestrated the gods’ downfall centuries ago. The series concludes with a resolution that redefines the relationship between gods and humans, leaving room for future exploration of this intricate world.
