A person who has fallen in love with a wonderful person is not necessarily a wonderful person themselves.

The Kingdom of Aristeria. One chosen by God, called the Holy Maiden, constantly maintains a barrier to prevent monsters from the forest from invading the kingdom. Only one Holy Maiden appears in the kingdom. One month before the current Holy Maiden passes away, a sacred mark appears on the right hand of the one who will become the next Holy Maiden. The mark possessed by the Holy Maiden shines in rainbow colors, but only the current Holy Maiden's mark glows. The next Holy Maiden's mark remains black until the previous Holy Maiden passes away, and they cannot use holy power until their mark shines. The current Holy Maiden has reached 85 years old this year, and her decline had become so evident that everyone thought, "Perhaps a new Holy Maiden will be chosen soon?" In fact, individuals bearing sacred marks have appeared. Moreover, there are two of them. Which one could be the true Holy Maiden?
