Himeko Nonohara

Himeko is the protagonist of the series. She progresses from being a tomboy at the beginning of the series to becoming a refined, feminine and mature girl by the series' end. Erika, her counterpart in the Land of Magic is an elegant princess, but warms to Hime-chan's playfulness which often lands them both in trouble with the King and Queen and Erika's magical broom, Chappy. Himeko had a childhood crush on the much older Hasekura-senpai, but she gradually grows to like Daichi instead. The name Himeko means "little princess". Hime-chan's motto is "Ike! Ike! Go! Go! Jump!". (Come on, Come on, go, go, jump)
