Chichi wa Eiyuu, Haha wa Seirei, Musume no Watashi wa Tenseisha.

As a girl of both spirit and human blood, eight-year-old Ellen has power over the elements—though not the traditional four. She can transform her surroundings by manipulating the elements of the periodic table. On top of that, Ellen also has a great amount of scientific knowledge due to being a scientist in her past life.

In a sudden, devastating demon attack, the spirit magician Rovel Vankreift, eldest son of House Vankreift, was fatally injured. The Queen of Spirits, Lady Origin, had fought by Rovel's side; she saved him from the clutches of death by bringing him to the spirit realm, and Rovel was pronounced the nation's hero. The two fell in love and had Ellen—who, thanks to her extraordinary parents, was born remarkably powerful.

But even this wholesome family of three, each quirky in their own little way, has its fair share of problems. Ellen and her parents are forced to reconnect with the Vankreift household to defend their relatives' honor, all while hiding Ellen's dangerous existence from the public to preserve their undisturbed happiness.
