Kami no Niwatsuki Kusunoki-tei

Since childhood, Minato Kusunoki could see supernatural beings, especially friendly ones. Soon after his mother leaves him in charge of a vacant house in the countryside, he draws the attention of a wolf-like mountain god named Yamagami, who is intrigued by the unusual purity surrounding the residence. Through Yamagami's guidance, Minato discovers the source of this mystery: anything written by his hand—regardless of the surface or the words themselves—carries the power to exorcise evil spirits. As more visitors arrive, Minato becomes the caretaker of an abode that now stands at the boundary between the human and divine worlds. At the same time, though still unfamiliar with the full extent of his powers, he begins to realize that they may have uses beyond simply keeping the area free of malice. [Written by MAL Rewrite]
