The Letter From The Outside World

He was supposed to be in an entirely different universe, an entirely different surroundings, and an entirely safe castle to reside in. Unfortunately, he was Hatake Kakashi; the universe's favorite play thing.

In which a certain Hatake is revisited by his not-so-old past in a simple guarding mission. Or, in which the universe decides to throw demons at Kakashi yet again. This time, she uses another world to do so.
