Precious Gem Stone - Sword Art Online Based off the characters from Sword Art Online placed in an alternate universe. I do not own Sword Art Online. The story contains Kazuto x Asuna fluff and lemon material. In an alternate universe written in Kazuto's perspective as a normal 16 year old who has a passion for basketball. Basketball was all he ever thought about until he met her, Asuna, his angel. Asuna opens Kazuto's eyes to the world besides Basketball. Also to what a relationship does to a person and how couples overcome certain urges. Enjoy.
