After escaping from a lifetime of captivity, sixteen-year-old Emma finally reaches the capital city of Hawk Eye. However, her arrival triggers an unexpected response from every man in the city - including the king - who falls deeply in love with her. Emma's fate seems sealed, as she is about to be forced into an unwanted marriage, but a sorcerer appears just in time to rescue her.
The sorcerer, Shion, is one of the nation's most talented and youngest mystical practitioners. Although Emma has no memory of their previous encounter, Shion reveals that she is cursed with the Echidna, a rare magical condition that occurs once every five centuries, wherein a girl is born with a heart pulsating with such potent dark magic that it could potentially endanger the world. Emma must beware, as others may try to hunt her down and seize her heart's immense power for themselves.
Shion proposes a solution: There exists a ritual that can release Emma from the Echidna's curse, but it demands a long and strenuous effort. Emma and Shion must marry each other to begin the process.
