One day, a charming and mystical girl, Fuka, appears before Yuichi, as a transfer student to his high school. From that moment on, mysterious phenomena start to occur around Yuichi. Fuka tells Yuichi that she is the last white witch in the world, the only successor to the white magic witches who use the magic of love. Yuichi feels perplexed by her revelation at first but gradually finds himself attracted to Fuka. But Fuka disappears from Yuichi's sight without a word. Five years later, they coincidentally meet again, only to discover that it is the beginning of the furious battle between white magic and black magic.
