Sword art online

So you've chosen the Sword art online universe now all you have to do is choose your character. Is it an original character that you came up with on your own? Or is it a character from the Sword art online universe? Maybe its a cross over character where you take a character from another book, movie, TV show, game, manga, or comic and insert them into the Sword art online universe with the universal acceptance power. Make your choice.
