Fushigi no Kuni no Senichiya

From xkazemg: A slapstick/parody loosely based on One Thousand and One nights and other children’s fantasies. Princess Seblan was brought up as a prince to save her life… and she later turns into a real prince and lives happily ever after with his wife. Together with his sometimes-sarcastic magical horse Hendek, Seblan ventures out into the world of fairies, dragons, and other mystical creatures.
