[[caption-width-right:300:The retelling of a boy involving change with magical girls.]]

''[[https://www.fanfiction.net/s/10389851/1/Guilty-Crown-The-Lost-Kingdoms Guilty Crown: The Lost Kingdoms]]'' is a retelling of the ''Anime/GuiltyCrown'' series with the five magical girls from ''Anime/PuellaMagiMadokaMagica'' as AU guests. It somehow averts the tropes use in typical crossovers, and serve as a movie fic with nine chapters.

The setting is also a stand-alone AU of a notorious fanfic franchise called Fanfic/YuYuGiDigiMoon, in which the outbreak of Lost Christmas (taking place in December 2012 instead of 2028 to coincide real-life predictions) wiped out most of Japan’s heroes. This serves as a background and new plot twists unlike the show for the characters to interact in dark times.
