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.

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.
