When the bumbling Himeko Tsubaki was late for tennis practice one day, she had no idea that she'd stumble, literally, into becoming royalty! After accidentally donning a magical crown that was stolen by the thieves Karen and Leslie, Himeko finds her status upgraded to hime-sama - a queen! Many desire the crown, such as the thieves themselves and a gibberish-speaking little girl; but the worst thing of all is that Himeko is unable to remove the crown from her head!
Satoshi and Arumi have been friends since early childhood, but now Arumi's family is moving to Hokkaido, deeply upsetting her long-time friend. However, when Arumi's grandfather accidentally breaks the pelican statue atop his restaurant, the duo find their world turned upside down and not quite as they left it. From a fairy tale kingdom, to kung fu China, to the prehistoric age and everything in between, Arumi and Satoshi can't quite seem to figure out where they are, or better yet, how they can manage to get home to their own Abenobashi Shoutengai!
