Plot

In an alternate time and place, the Daughters' Kingdom is home to beautiful girls who live a peaceful life and have four loyal guardians. Every year, at certain times of the year, holy water would flow from the Daughters' sacred altar, which was the secret of the Daughters' population. The ancestors used the power of the sacred spring to build a border for the Daughters' Kingdom, but they were cut off from the rest of the world from then on.
