異界の導き手からもたらされたテクノロジーと魔力が融合する閉ざされた王国で、代々魔力を持つ者だけが特権階級に属し、その魔力で紡がれた糸が動力源となる世界。王侯貴族たちは風、水、火、電気、それぞれの魔力属性を象徴する髪色となり、魔力を持たない平民たちは茶や黒髪で生まれてくる。そんな魔力特権階級の世界で、ロレッタは伯爵令嬢でありながら庶民の象徴である黒髪の不貞の子として生まれてしまった。その存在を隠されるように育てられた不遇なロレッタに、新たな運命が訪れる――!!
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 was born an unfaithful child with black hair, the symbol of the common people, even though she is a countess. Raised in such a way that her existence is hidden from the world, the unfortunate Loretta is visited with a new destiny–!
