めいどいんばに～

Just when Elena and Galu heard the alarm, a Succubus as well as the mysterious lady popped out of nowhere wanting to hold Prince Galu captive. Elena tries to defend the prince but fails. Galu decides to give in since he doesn't want to see Elena get hurt. The succubus then carries Elena in the air and flew out of the castle to get rid of the maid. A slip in the hand made Elena free fall into the ground from the air.

In the meantime, Revea, a royal magician who lives outside the castle sees the invasion of the Dark race. She tells her student Yuri the white mage, to go and find the legendary hero and save the kingdom. Yuri leaves and finds Elena climbing up from the ground where she fell from the sky. At the same time a bunch of monsters popped out of nowhere. When asked by Yuri if she has any weapon, the only thing Elena has is a feather duster. Yuri then uses his magic to enlarge Elena's duster, making her be able to slap the monsters and destroy them. With this enlarged duster as her weapon, Elena along with Yuri have to find a way to get back into the castle (which is now protected by a force field) and save Prince Galu.
