A meteorite made of a substance unknown to the periodic table crashes on the border of Rosellon and Akamot. After failing to secure total control of what would be known as Krydium, King Ito of Rosellon is forced to abdicate in humiliation. He and his brother, Prime Minister Toshiki Ichimada, are replaced by Grand Councilor Adama Keita as the nation's head of state and government. Crown princess Rika Ichimada rages at having the throne she was to inherit ripped away. In her anger, she realizes the effect of Krydium on a person's DNA as she is gifted with the power of telekinesis.

Five years later, Rosellon is embroiled in a crisis with its renegade paramilitary, led by the former prime minister. The grand councilor's daughter, Aminata Keita, is a Krydian with the power to manipulate energy. Motivated by the assassination attempt on her father at her graduation, she decides to become a soldier in the army of Rosellon.

In the twisting path that conditions her to develop as a soldier, she is placed in the company of the country's 180 most powerful soldiers under the command of captain Rika Ichimada. While Aminata seeks to put an end to the former prime minister's fury, the captain plans to claim the crown she never received at any cost.
