## Description
In the west-central region of Lunoche of the Raulbhach continent, there’s a legend of a great pirate who hoarded up many treasures, defeated demons by himself, vanquished other pirates and established a nation. His name was Gautherio Bonezzi, the greatest ruler of the seas who achieved everything that he desired. However, that was not the end of the tale about the “King of the Coral Sea”. Several hundred years later, he appeared once more on a ghost ship, proclaiming that he would grant an audience to the one who gathered all six rings to prove their worthiness and fulfill their wishes.

It seemed like just an old tale that could be passed off as a bedtime story, but then there were reported sightings of a ghost ship out at sea. Excited that the legend is indeed true, people began to battle with one another to collect the rings before the great king disappears again.

## Characters
### Agnes (アニエス)
An 8th-rank Apsael angel long tasked with the governance of the Lunoush archipelago, she is afflicted by a curse which brings misfortune to herself and to all around her. Agnes believes the source of her curse is a direct result of a previous appearance of the Coral Sea King and the struggle accompanying the quest to assemble the rings. She joins the ring hunt in hopes of dispelling her curse and to ensure no one else is made to suffer the same fate she did.

Agnes runs an orphanage she established shortly after she was afflicted with her curse. Due to the effects of the curse, she is financially constrained by the demands of the orphanage's upkeep and the occasional redemption of slave children from cooperating merchants.
