Freshly graduated from middle school, loner Yanagi Yukito finds himself spirited away to his childhood home on the Ayaka Islands. There, he discovers that he is descended from a line of magic users known as Ley Masters.

Jingi takes Yukito on his first job to pacify an Ara-Mitama chasing people away from the local canal, but the origin of the problem may be closer to home than either of them believed.

Yukito and Jingi visit the First Island, a popular tourist destination. There, they meet Ibuki, another former disciple of Yukito's father, but one who has a very different view on how to handle Ara-Mitama.

Yukito learns a bit more about his father's legacy and the lasting impression he's left behind on the people of the Ayaka Islands. During a visit to his grave, he runs into Ibara, Aka's stonefaced associate.

Yukito tries to fend off the Ara-Mitama with Ibara, Chataro, and Yuko. When Aka and Haruaki arrive to help, things get heated as their ideals clash and emotions run high.

A glimpse into the halcyon past when Aka, Haruaki, and Jingi were Makoto's young disciples, and how Makoto stepped up to save the Ayaka Islands one fateful night when disaster struck.

Yukito attends a summer festival with all his new friends as he tries to enjoy some semblance of a normal life for a boy his age, but the evening's peace rests on shaky ground.

The Ayaka Islands prepare for an evacuation after the eruption on the Fourth Island. As everyone makes their own preparations to try and help save the islands, Yukito discovers the truth about his identity.

As the fire dragon rampages and threatens the future of the Ayaka Islands, Jingi steels his resolve and prepares to follow through on a promise he made years ago.

The Ayaka Islands are safe again thanks to Jingi, but his choice causes ripples of emotions through the island's inhabitants and strife among the Ley Masters. In his despair, Yukito sees a light in the darkness, and makes a decision of his own.

Yukito takes a leap of faith and dives into the Ley Energy, and encounters a certain soul while searching for Jingi. On the outside, the other Ley Masters band together to help lead him home.
