One day, something went wrong with Ein’s alchemy, causing him and dragon girls Lime and Sheena to be transported to the Far East. They were surprised to find themselves in an unfamiliar place and were invited to meet the castle lord. He sensed their dragon power and asked a favour of them: to rescue his daughter Kukuri-hime who was kidnapped last night. After successfully bringing her back, they return to search for a way to return to Erile.
