"Neji-Shiki" is a manga series that blends elements of psychological horror, mystery, and supernatural intrigue. The narrative centers on a young man named Shiki, who becomes entangled in a series of bizarre and unsettling events after moving to a remote village. The village is shrouded in secrecy, with its inhabitants harboring dark rituals and an ancient curse tied to the concept of "spiral patterns." These spirals, which appear in various forms throughout the story, symbolize the cyclical nature of fate, death, and rebirth, serving as a recurring motif that drives the plot forward.

Shiki's arrival coincides with a string of gruesome murders, each marked by the presence of spiral imagery. As he investigates, he encounters a cast of enigmatic characters, including Kirie, a local girl with a mysterious connection to the village's history, and a series of antagonists who embody the curse's influence. The story delves into themes of inevitability, existential dread, and the inescapable pull of destiny, as Shiki uncovers the village's ties to a cult that worships the spiral as a divine force.

The plot unfolds through a series of interconnected arcs, each revealing more about the curse's origins and its impact on the villagers. Shiki's journey is marked by a growing sense of paranoia and helplessness, as he struggles to break free from the spiral's grip while confronting his own mortality. The narrative is punctuated by moments of visceral horror and surreal imagery, creating an atmosphere of unease that permeates the series.

Key characters include Shiki, whose curiosity and determination drive the story; Kirie, whose tragic backstory and connection to the spiral add depth to the narrative; and the cult leaders, who serve as both antagonists and embodiments of the curse's power. The interplay between these characters and the overarching mystery of the spiral curse forms the core of the series, culminating in a climactic confrontation that challenges the boundaries of life, death, and human will.
