In this school fantasy story set in the distant future, creatures contaminated by pollution have overtaken the land, forcing humanity to live in isolated mobile cities called Regios. One such city named Zuellni is a self-contained school in which freshman Layfon Alseif has just enrolled. Layfon reluctantly joins the 17th Martial Arts Studies Unit led by the third-year student Nina Antalk and embarks on a series of adventures. This version recounts a slightly different version of Layfon's story. Here, Felli is the main character. Same world settings as the original novel.

In a closed kingdom where technology and magic power are fused together by a guide from another world, only those with magic power from generation to generation belong to a privileged class, and the thread spun by that magic power is the source of power. The royalty and nobility have hair colors that symbolize their magical attributes, such as wind, water, fire, and electricity, while the commoners, who have no magical powers, are born with brown or black hair. In such a world of magical privilege, Loretta is a noble who possesses black hair as she was born from her mother's infidelity and is raised in such a way that her existence is hidden from the world. The unfortunate Loretta is visited with a new destiny.
