In a mythical world where humans and gods coexist, a ceremony marking the new governing princess is about to occur for the first time in 60 years. Only a girl from the Hime Clan may take this position, but the lack of females born to this family means that a boy called Arata must pose for the role. Meanwhile in modern-day Japan, a boy named Arata Hinohara is starting his new life in high school. He wants to put memories of his difficult past behind him, but things aren't going to be simple when he discovers a mysterious connection to the first Arata...

Arata Hinohara has so far emerged triumphant from his encounters with those who would stop him in his journey, but now he must face Ikisu, an enemy who wields power over emotions. This power wreaks havoc among Arata and his companions, promising to isolate Arata so that Ikisu can confront him without interference. Arata does what he can to thwart Ikisu, yet just when it looks as though he might take command of the situation he loses his grip and commits an act for which he may never be able to forgive himself
