Are you the one who's supposed to be my Master?

...No, wait... Where is this? How did I become Artoria? But... this... isn't so bad, I guess...

This is a story about the perfect meeting between King Arthur and a girl from Gensokyo.

A brief parting is for the sake of a better reunion... No! Actually, it's so we can be together forever!
