Ushiromiya Battler was on his way to Rokkenjima in the Izu Islands to attend the annual family conference, a day later than his relatives because of his school schedule. Battler, who is not interested in the conference, is looking forward to meeting his close relatives. When he arrives on the island, the first people he encounters are people who are not supposed to be there...

Long, long ago, there existed a world of magic and science. God, afraid of man's potential, split the world in to the world of science, Elde, and the world of magic, Fandavale. One day in Fandavale, a terrible witch named Cendrillon (Cinderella) revives. Cendrillon plots to rule both worlds, and searches for the "key" which holds tremendous power. A young boy from Elde by the name of Sōta meets a mysterious girl from Fandavale, Akazukin, and her talking wolf companion, Val. Sōta learns that he is the key Cendrillon is searching for. Now it is up to Akazukin, Val, and the other Fairy Musketeers to protect Sōta from Cendrillon and her Nightmarelians who wish to obtain the power he mysteriously possesses.
