Arata of another world called Amawakuni and Arata Hinohara of modern-day Japan switch places. An illusion hides the switch from people of both worlds, and Hinohara and Arata pass as each other. Kannagi, a wielder of special sword-spirits called Hayagami, has led eleven other wielders against their ruler Princess Kikuri and framed Arata, the sole witness. The Imperial Court convicts Arata and exiles him to Gatoya Island, but due to the switch, Hinohara goes in Arata's place. Kotoha, Arata's childhood friend, accompanies Hinohara and gives him Tsukuyo, a Hayagami that Hinohara activated before his trial. She also gives him a charm, through which he and Arata communicate. Barely alive, Kikuri also speaks to Hinohara through the charm and tasks him with restoring order to Amawakuni. Hinohara escapes Gatoya, learns to use Tsukuyo, and gains allies, including Kannagi. As he defeats the other rebels, Hinohara learns Masato Kadowaki, a bully from his past in modern-day Japan, has followed in his footsteps. After switching places with Harunawa, one of the mysterious Six Shinshō, Kadowaki activates a Hayagami of his own, Orochi, and faces Hinohara in multiple fights. Along the way, Hinohara and Kotoha grow close, and their relationship complicated when Kotoha discovers Hinohara's true identity and when he loses control of his growing power and hurts her. In modern-day Japan, Arata adjusts to high school and befriends Imina Oribe. Imina, a woman from Kikuri's clan who winded up lost on Earth fifteen years prior, is the true heir. Harunawa, who passes as Kadowaki, plots to kill Imina and end Kikuri's line. Arata and Imina search for information in prophecies on how to foil the Six Shinshō's ambition to rule both Amawakuni and Earth. Harunawa attacks the school and infects the city to augment his powers. Imina counters the outbreak with her Amatsuriki abilities, unique to women of her clan, to protect Arata and the Hinohara family.

Reception
Rebecca Bundy of Anime News Network gave the first volume an overall B+ for "Great art and character designs; plus, Watase's ability to create interesting lore is as sharp as ever." She also noted, however, that the "Pathetic, cowardly main character makes everything involving him painful to read." Deb Aoki of About.com notes that the plot is "fairly formulaic fantasy fare that's just a bit too predictable to offer fans something truly fresh and new" but that the series has her "hooked." Todd Douglass of Blogcritics.org says that the first volume is "strongly recommended," despite some reservations. Christopher Nadolsk of Mania.com says that the first volume offers "an entertaining and eye-pleasing escapist fantasy read."
