Reyna Charlotte Ashford, the 「Hero of Light」had successfully repelled the Demon Lord's army and saved the world. She wanted no wealth or reward other than to be left alone to live her life. Hiding herself away in her hometown of Verdantia, she merely lives day to day doing tasks for the Hunter's Guild. The Goddess of the Oath, Fairyluna found that end for the hero simply unacceptable.
"How can the Hero who saved this world go unloved? It's madness!"
Using her godly powers, she unleashed a summoning circle to bring forth the Hero's true love, wherever they might be. The Hero, ambushed alone by a horde of monsters lay dying under a tree as a scene of carnage lay before them.
The summoning circle brought forth a young woman from Earth, Kiyome, to that hell scape. Wearing a pure white wedding dress and ring, and holding another ring in her hand.
"Traveller, will you save the Hero of this world? All you need do is place that holy ring on their finger, and say 'I do.' "
