In the southeastern corner of Gravania lies the Kingdom of Palanthein, once celebrated for its artistic grace and the philosophers whose ideas shaped generations. But behind that, social inequality plagues the country and makes its people begin to wonder, is our beautiful country really that beautiful? By what right do aristocrats decide our lives? Is the title of king really useful?

Meanwhile, across the northern strait an ancient race hides on a isolated island. Long ago, they ruled over mankind with cruelty and chains. Now they wait in silence, but rumors of their return grow with each passing year.

Along with the unstable situation on the continent of Gravania, a girl with the characteristics of a jet-black hair and blood-red eyes wakes up from her coma. Is her awakening merely a coincidence amidst the chaos, or is it a destiny that will change the course of Gravanian history forever?
