Rider
Rider sighed at his response. Amusingly, though, despite his obvious insanity, he wasn't actually that far wrong. She was, after all, certainly from another dimension and, whilst she was not a princess, she was a fallen goddess. Still, despite him having stumbled upon something vaguely resembling the truth, she could tell that talking to him was going to be taxing and, after pondering what to say for a few moments, she decided she simply couldn't be bothered to correct his false impression, especially since she had no desire to explain her true nature to him right now.
"Eh, that's close enough, I guess", she responded with a somewhat-forced smile.
Then she held out her hand.
"I'm Rider", she said. "Nice to meet you."
