The Takagami brothers return to their mother's hometown only to find out that she was the last Priestess of the Water and that the elder sibling, Noboru, is now the head of the Mizuchi Family. Tōru, on the other hand, is currently being targeted by Yōkai for the power he possesses. In order to protect him, the Guardian spirit, Kūgen Tenko, is released from the seal that held her captive. Later that night, the enemy attacks and it requires both Kūgen and the sentinel Kō's combined abilities in order to vanquish the evil spirit. Afterwards, the brothers return home with both Kūgen and Kō, who will both serve as their guardians from spirits who mean to do them harm.

After getting permission from Noboru and Tōru's father, Kūgen and Kō are allowed to stay in their house. Kūgen shifts into his male form and asks Noboru to bring him to the town's Shinto shrine, in accordance to the custom where a spirit has to ask permission from the local god before using his powers. They discover that the owner of the local convenience store is the local god, Ebisu, who serves as the patron of merchants. After accompanying Ebisu to the shrine, Ebisu orders his shrine's gatekeepers—a pair of imperial guardian lions named Kōga and Eiga to attack Kūgen's group. A battle then ensues which Kūgen wins after "summoning Shin" from the sky. Ebisu then explains that he was only trying to destroy his temple to attract more business. Ebisu also tells Kūgen in private that Miyako's spirit still haunts the land.
