A modern world is suddenly and strangely tied together with a mystical 7th century East Asia. Mythological beasts still roam the wilds while the Three Kingdoms of Korea and the clans of Yamato Kingship Japan struggle to maintain order. Lucas, fatalistic Korean-American who has only ever wanted to find someone and start a family by the sea; Mitsuko, a Japanese 'office lady' programmer who knows she can do more with her life but doesn't know how; Akari, ousted Koga clan warrior princess who doesn't believe in dilemmas or gender roles; Joshin, enthusiastic Goguryeo Buddhist disciple who is as naïve as he is sincere, yet a fearsome fighter - their lives will be forever intertwined. How will they face love, demons, and American health insurance?
