There isn't a widely known and clearly defined 'love story' in the traditional sense between Kukulkan and Quetzalcoatl in a single unified narrative. However, both are important deities in Mesoamerican cultures. Kukulkan was a Mayan deity often associated with snakes and the sky. Quetzalcoatl was a significant Aztec deity, often depicted as a feathered serpent. They share similarities in their serpent - like forms and their connection to important aspects of the cosmos, but there is no common, well - established love story between them.
I'm not sure specifically as there could be many different takes on this. It might be about Percy being in a dangerous situation and Quetzalcoatl, a powerful figure from mythology, coming to his rescue in the context of a fan - created fictional story.
FGO isn't a typical visual novel. It has more gameplay mechanics and character-building features. The story is presented along with battles and strategic decisions.
It's likely that the main characters from the original 'Highschool DxD' series would still play important roles. Maybe Issei Hyodo would be there, adapting to the new quetzalcoatl - influenced environment.
There's no way to know for sure who the author is without more information. It could be anyone who is a fan of the relevant source material (maybe Percy Jackson series) and has an interest in Quetzalcoatl from mythology.
There were the following FGO-related novels:
"FGO's Journey to the Other World,""Lu Mingfei Challenging FGO,""Starting from the Collapse of the World with the Card Drawing System,""Running FGO in the Ninja World,""King Arthur's Comic Journey,""Yuki's Holy Grail Journey,""The Story of Chaldeans Landing and Becoming the Director,""Saving the World from the Collapse," and "Chaldeans in Marvel." These are the different types of novels about FGO. There might be games-game systems, light novels-derivative doujinshi, funny jokes, infinite universe-infinite, and so on. I hope you like this fairy's recommendation. Muah ~😗
I'm not sure what 'First Lady' refers to because the name could refer to different people or characters. Can you provide more context? This way, I can better answer your questions.
In some of these fanfictions, there could be a focus on the mythology of Quetzalcoatl integrated into the Highschool DxD universe. This could lead to exciting tales where the characters have to face off against threats related to this ancient mythology while also dealing with the typical high - school drama and the battles that are characteristic of the DxD world. There might be new magical abilities or artifacts inspired by Quetzalcoatl that change the course of the story.
