Jin Mikuriya creates a sculpture of a young woman from the wood of his ancestral tree for an exhibition. When he tries to leave his house, the statue cracks to reveal a young woman. She explains that she is a goddess named Nagi, and when she asks Jin how he created a vessel to materialize her, he reveals he used wood from his family's ancestral tree. Nagi and Jin go to what used to be Jin's family's shrine to find that the tree has been cut down and there are impurities in the area. Both of them return to Jin's house, where Nagi watches a magical girl anime on the television. Inspired, Nagi returns with Jin to the shrine, and while he holds the impurities, she destroys them with an improvised exorcist staff. In the end, Nagi decides to live at Jin's house, which he reluctantly accepts.
