Kotoha is a Flame Deity known as the Princess of Phantasms, who inherited her mother's legacy. Unfortunately, when her title is stolen by the nefarious Tenzen Shimazu, she is to be wed to him as her perfect record of being undefeatable is tarnished. To suffer this humiliation further, she will no longer lead the Night Parade that her mother led years ago, and Tenzen now has control over the lands and territories that her mother once held. How will Kotoha get out of this situation? Can she claim back the people's heart's once more for her failure?
