I knew what all of that meant Shinto. I studed religions in school and I research different types of swords. (Note that the katana is my second favorite type of sword)
I got mine from the main villain I made a series of books called "The Book of the Ado" Ado is the word for one in an ancient language that has to do with my books. I also add him in ALL my fan fics involving FFVII-FFIX.
Also, Avara means either "chosen" or "fallen" in the ancient language mentioned earlier. The unknown meaning of Avara is a key part of my books.
