Artoria is currently 14 years old, a transmigrator from Earth. At first, she thought she had simply transmigrated to a parallel world and happened to transform into someone else.
Then, under Merlin's tutelage, she followed the dictates of fate, pulled the Sword in the Stone, and became King Arthur. She married the beautiful and wealthy Guinevere, then got close with her elder sister, the Queen, and had little Mordred.
Finally, she changed the story and set off toward a happy life. But after living for so many years, she only then learned that this was the world of Ultraman!
She'd gotten all ready to pull the sword, and then a monster showed up. Oh, screw this...!!!
