ข้อมูลอนิเมะKannagi: Crazy Shrine Maidens

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 ancestral tree. Nagi and Jin go to Jin's family 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 takes a wand to the shrine, and while Jin holds the impurities, she destroys them. In Jin's house, Jin attempts to plan living arrangements for Nagi, who is fascinated with modern technology and items. As the two go to sleep, Jin realizes how human Nagi seems after she goes to the bathroom in the middle of the night.

Nagi and Jin are surprised by Tsugumi Aoba, a classmate and friend of Jin, paying a visit to him. Nagi sorts things out by fabricating a story about her being Jin's half-sister who started living with him. Later, Nagi and Jin end up having a serious discussion and she flees the house. Nagi returns to the sacred tree's place and finds a kid playing there with an impurity in his body. Nagi tries to cleanse it without Jin's help, just to find herself in danger. Jin appears in the nick of time to save her and he ends up carrying an injured Nagi back home.

Jin and his clubmates Daitetsu Hibiki and Meguru Akiba receive the task of cleaning an old storehouse from their seniors at the art club. Upon arriving there, Jin finds a spider-like impurity wandering there, but he ends up hiding the fact from Nagi. However, she becomes suspicious about his behavior and borrowed one of Tsugumi's spare uniforms to infiltrate the school. Nagi tagged along Jin and his classmates to figure out the mysterious being knocking from the cellar at the storehouse, just to find out that it was a teacher from the school whose studio lies under the floor. Nagi continues to search for the spider-like impurity, only to find a mysterious girl, who addresses Nagi as her older sister, easily destroying it.

Nagi figures that her sacred tree is uprooted and discusses with Jin about how she must find another object of worship to replace the tree, otherwise her powers will continue to wane until she disappears completely. Akiba tells Jin, who was questioning his classmates about idols, about a popular girl named Zange, the mysterious girl who Nagi met at the school. After Jin had an encounter with Zange herself, Nagi learns about her popularity, and after a little investigation, she also suspects that Zange may be possessing a human body. Her theory is proven true when she confronts Zange herself, who claims that a girl named Hakua Suzushiro is acting as her vessel "by free will". Just when Zange manages to put Nagi at her mercy, Jin appears and becomes shocked with the scene. Late at night Zange appears at Jin's place, stating that she will take care of him from then on.

Jin discovers that Nagi is becoming popular between the students at his school, to the point of having a famous website and a huge fanclub. However, the teachers became worried about her influence with the students, and Nagi ends up confronted by one of them who happens to be Hakua's father. He easily figures that Nagi is a god just like Zange and questions her about her intentions. After stating that despite having her reasons to be with the students, she has no intention to harm them, Nagi is brought to the principal's room. While the studens cheer for her, Nagi discovers that her godly powers increased a little, and the incident is settled with her officially enrolled at the school.

Jin arranges for Tsugumi to help Nagi with shopping. Nagi is happy at first, until she finds out that the money she got from Jin is too low, and she decides to look for a part-time job to help with expenses. She starts working at a maid café where Tsugumi is also working by request of a friend. Both did not expect to meet acquaintances at the café, until they are surprised by Jin and his fellow clubmates from the art club. Jin, unable to stop looking at Nagi as he found her too cute in her maid attire, ends up causing a scene when she approaches him, and Nagi decides to stop working there.

Nagi gets angry at Jin and shuts herself into his closet. Despite Jin and his friends' efforts, Nagi refuses to set foot out of it. Later it was explained that Nagi's reason for her anger is that Jin accidentally erased a taped episode of Nagi's favourite anime show before she watched it. After Jin gives up trying to get her out the closet by force, he finds that Nagi had already left by herself, much to his own anger.

Jin's clubmate Daitetsu is sheltered in his home during a stormy night. While pondering about Jin and Nagi's behavior, he starts wondering about their feelings for each other, and later, if they are really siblings at all. During dinner, Daitetsu confesses that he stole the cut down ancient tree Jin used to bring Nagi to life. Nagi got angry at him, and stated that he would be cursed by the gods. Full of remorse, and really in fear of some divine punishment, Daitetsu runs for the place where the tree was and asks forgiveness to the gods, and Nagi uses her powers to protect him from a bolt of lightning, collapsing soon later, much to Jin's worries, as he had seen her in this state before.

After witnessing a heated discussion between Nagi and Daitetsu about Jin, Tsugumi and the other members of the Art Club started questioning themselves about the true nature of Jin and Daitetsu's relationship. Later, Tsugumi accidentally makes the discussion get public, and rumors about the duo being a homosexual couple started to spread, much to their own troubles. A friend of Tsugumi encourages her to bring the topic to Zange, who decided that the best solution to the problem is for Jin to officially date a girl, and she offers herself to do so. Later at Jin's house, Tsugumi apologizes to him and he is asked by them to choose between dating Zange or her to clear out all misunderstandings, until Nagi suggests that both should be trying to get his affection in public as a "fitting solution". However, having two girls fighting so fervently for Jin at school ends up fueling even more bad rumors about him.
