Hymn of the Teada

"Time doesn't work the same for all. As an imminent invasion looms over old Ryukyu, the high priestesses are engaged by Ryotetsu, a court official in the old kingdom. He implores their guidance to prevent the impending injustice. He embarks on a mission to find the one person who wields the power to change the course of History. He discovers that the one he seeks is a 17-year-old high school student from far away."
