Core Premise

Ellen, a former Japanese scientist reborn as a half-spirit (human/spirit hybrid), has the ability to manipulate the elements of the periodic table, allowing her to create complex substances. Her father, Rovel Vankrieft, is a renowned legendary human hero who saved the kingdom. Her mother, Origin, is the Queen of the Spirit Realm.

• Political Intrigue & Royal Conspiracies: The plot frequently involves the family navigating centuries-long dark history and royal conspiracies. Themes of corruption and external threats to the family's peaceful life are prominent, as seen in conflicts with the royal family who wish to exploit Ellen or Rovel's power.
