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

In her previous life Ellen was a scientist in modern Japan. She is reborn as a child in a magical world and into a family unusual even by its standards: her father Rovel is a legendary hero, her mother Origin is the queen of spirits, and Ellen herself is a half-spirit able to manipulate chemical elements.

The family tries to live happily away from court, but Ellen's bloodline and abilities make privacy difficult. When politics and noble ambitions begin closing in, she combines the mind of a scientist with spiritual power. Her goal is not to become the greatest mage or hero. She simply wants to protect the warm family she was fortunate enough to receive in her second life.
