' Sora and Shiro's surname was said to be "Nai" by the author.[1] This can be interpreted that their surname is literally Nai or that they have no surname, as Nai (ない) in Japanese means none. It can also be interpreted as a joke, because when combined with their first name, Nai Sora (ない空) means "not empty" or "not Sora." '

That means "Nai Sora" meaning Not Sky, implies Land. "Nai Shiro" Not White implies Black.

Not a coincidence
