"Shabake" is a supernatural anime series that blends elements of Japanese folklore, mystery, and drama. The narrative centers around Suzuhara Izumi, a high school girl who discovers she is the descendant of a powerful onmyoji, a practitioner of ancient Japanese esoteric cosmology. After her grandfather's death, Izumi inherits a mysterious box called the "Shabake," which contains a collection of supernatural artifacts and spirits bound to serve her. These spirits, known as shikigami, each possess unique abilities and personalities, and they become central to Izumi's journey as she navigates a hidden world of spirits, curses, and ancient rituals.

The plot unfolds as Izumi begins to encounter various supernatural phenomena tied to her family's legacy. She learns that her grandfather had been a guardian of the balance between the human and spirit worlds, and his death has left a power vacuum that threatens to disrupt this equilibrium. As Izumi takes on the responsibility of maintaining this balance, she is drawn into conflicts involving malevolent spirits, rival onmyoji, and ancient curses. Alongside her shikigami companions, she must solve mysteries, exorcise dangerous entities, and uncover the truth behind her family's history.

Key characters include Izumi's shikigami, such as the loyal and protective Byakko, a white tiger spirit, and the mischievous yet resourceful Suzaku, a phoenix-like entity. Other significant figures include rival onmyoji who challenge Izumi's authority and enigmatic spirits with their own agendas. The series explores themes of duty, legacy, and the coexistence of humans and spirits, all while maintaining a balance between episodic supernatural cases and an overarching narrative. The interplay between Izumi's growth as an onmyoji and her relationships with her shikigami forms the emotional core of the story, as she learns to harness her powers and confront the challenges of her inherited role.
