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

Ellen was once an ordinary person living in modern-day Japan, but after reincarnating into a fantasy world, she discovers she has been reborn as a half-spirit. Her new lineage is nothing short of extraordinary. Her father, Rovel, is the legendary hero who saved the kingdom, while her mother, Origin, reigns as the primordial queen and absolute ruler of all spirits. To top it off, Ellen herself possesses the overwhelming ability to manipulate the very elements of nature. Despite her godlike heritage and immense power, Ellen appears as nothing more than an impossibly adorable little girl. Yet beneath her innocent exterior lies the sharp mind and memories of her previous life. She refuses to let her family's prominent status make them targets for danger. Instead, she quietly prepares to use everything at her disposal to keep them safe. By combining the practical knowledge retained from modern Japan with her unparalleled command over elemental spirits, this perfect child is determined to shield those she loves most. No matter what threats approach her heroic father or her spirit queen mother, Ellen will draw upon both her past life's wisdom and her extraordinary magic to protect her precious family at all costs.
