The complete anime of Kaikai Guardian God is adapted from a ghost-themed manga created by Hamada Yoshikazu. It tells the story of an ordinary high school student Kagami Ichiya and a beautiful girl who claims to be his master, the Fusang God Kiriha, who live together in a strange way. But one day, a person who claims to be a messenger sent by the land god Kikurihime God, and a beautiful big-breasted witch Heiyao, appears in front of them. What is her purpose? Sleeping together and taking a bath together, this naughty and cute Kiriha, who doesn't look like a guardian god at all, does not play by the rules, always makes Ichiya go around in circles, making him live this kind of incredible life every day.
