Now, to get out through the mirror, they will meet again this rabbit that is not easy. When-Long ago a mysterious magician named Koto (almost like our heroine, only writing more) peopled the world with their creations, and she went to distant wanderings. So distant that even her name not everyone remember them, and the story itself is now nothing more than a legend. But three of the elders know - sooner or later it will come back, and koewho even suspect that the Koto, a girl from the real world, can be the key to return to "mom».
