Maquia is a member of a special race called the Iorph—mystical beings who can live for hundreds of years and remain separate from the lives and daily troubles of mankind. However, Maquia has always felt lonely despite being surrounded by her people, as she was orphaned from a young age. She daydreams about the outside world, but dares not travel from her home due to the warnings of the clan's chief.

One day however, the outside world finds her, as the power-hungry kingdom of Mezarte invades her homeland. They already have what is left of the giant dragons, the Renato, under their control, and now their king wishes to add the immortality of the Iorph to his bloodline.

The humans and their Renato ravage the Iorph homeland and kill most of its inhabitants. Caught in the midst of the attack, Maquia is carried off by one of the Renato that has gone berserk. It soon dies, and she is left deserted in a forest far from home, now truly alone save for the cries of a single baby off in the distance. Maquia finds the baby in a destroyed village and decides to raise him as her own, naming him Ariel. Although she knows nothing of the human world, how to raise a child that ages much faster than her, or how to live with the smoldering loneliness inside, she is determined to make it all work somehow.

While playing in the snow one day at her shrine, the land god Nanami Momozono witnesses her familiar—the fox youkai Tomoe—collapse, with dark markings appearing on his body. Tomoe's former master, Lord Mikage, appears after his long absence and places Tomoe into a magical pocket mirror in order to stave off his ailment. Mikage explains that long ago, before he and Tomoe had met, the fox youkai was in love with a human woman. Seeking to live as a human with his beloved, he made a deal with a fallen god, but he only ended up cursed and dying. When Mikage discovered Tomoe, the god made the youkai forget his human love as a quick solution. However, something has changed recently to reactivate the curse; Tomoe has fallen in love with his new human master, Nanami. Since there is no way to stop the curse, Nanami wants to stop Tomoe from getting cursed in the first place by traveling back through time, even if it means they may never meet. As Nanami travels back hundreds of years to save her precious familiar, she discovers that she is far more closely bonded to Tomoe than she previously thought. [Written by MAL Rewrite]
