Deep in the Japanese countryside, a young man named Minato Kusunoki is entrusted with the care of a sprawling, traditional house. The residence has a fearsome reputation, overflowing with evil spirits that have driven away all previous caretakers. However, upon his arrival, Minato unknowingly unleashes an extraordinary latent ability. His pristine and powerful handwriting possesses the unique property of exorcising evil miasma and spirits, and he inadvertently clears the entire house of its dark occupants with a single stroke.

In the absence of vengeful spirits, the purified Kusunoki residence becomes a beacon for a different kind of supernatural entity. A procession of unique and peculiar gods, or kami, is drawn to its newfound comfort and peace. The first to arrive is the sweet-toothed Yamagami, a great mountain god who appears as a giant wolf, accompanied by his fluffy, marten-like children who prefer Western-style sweets. Soon after, a sake-loving spirit turtle takes up residence in the pond, followed by a dragon with a taste for wine and a kirin who is partial to a certain brand of beer. Before long, Minato's garden transforms into a kami realm of perpetual spring, an eternal sanctuary where time seems to stand still.

Minato takes this strange turn of events in stride, embodying the gentle and relaxed pace of an iyashikei story. His daily life becomes a series of tranquil moments: enjoying tea and wagashi with the mountain god on the porch, going shopping for the specific treats each spirit favors, and simply relaxing in the company of his spiritual neighbors. His power does not go unnoticed by the human world, however. An onmyoji named Saiga from a government bureau arrives, recognizing the immense power in Minato's handwriting. He seeks to borrow Minato’s spirit-dispelling power, leading to a relationship where Minato’s everyday shopping lists are secretly used as potent talismans for exorcisms.

The narrative unfolds through episodic, low-stakes arcs focused on the slow, heartwarming life in the garden. One arc follows the arrival of new, eccentric gods, such as a difficult phoenix chick or rival deities of the mountain, and Minato’s gentle efforts to accommodate them. Another storyline sees the garden change its season at Yamagami’s whim, leading to cherry blossom viewings and harvesting bamboo shoots. Minato gradually learns to hone and recognize his own abilities with the help of the resident gods, using different inks and papers for different effects, all while the onmyoji deal with larger spiritual threats off-screen. The heart of the story remains Minato’s halcyon days as he lives peacefully, surrounded by gods in a garden that has become a little slice of heaven.
