Rovel Vankreift, the legendary hero of Tenbahl, returns home after a long absence from the Spirit Realm. Though he has come back to life, he is no longer the same. Ten years ago, Origin, the Queen of Spirits, saved him by healing his severe injuries with her magic, transforming him into a half-spirit being. They eventually married, and their daughter, Ellen, was born, inheriting her mother's spiritual powers and her father's human resilience.
Ellen's extraordinary intellect comes from her memories of a previous life as a dedicated chemist in Japan. With her deep knowledge of the periodic table and elemental transformations, she can manipulate the basic components of matter, turning one substance into another at will. However, revealing her abilities could upset the delicate balance between the human and spirit realms, attracting those who wish to exploit her powers.
While Rovel resumes his heroic duties, Ellen grows increasingly aware of the challenges ahead. Admired and envied in equal measure, the young reincarnator must discover her true identity as a bridge between two worlds and possibly become the key to uniting them.
