Plot... Miru!!

Plot . . . “Mirumo de Pon”

The main character, Katie Minami (Kaede Minami in the original Japanese versions), is a cheerful and energetic eighth grader who is shy around her male classmates, making it difficult for her to date. One day, on her way home from school, she walks into a mysterious shop and buys a blue cocoa mug. When she arrives at home, she peeks into the bottom of the mug and discovers an engraved note which says, "If you read this message aloud while pouring hot cocoa into the mug, a love fairy ("muglox") will appear and grant your every wish." The skeptical but curious Katie follows the directions and announces her wish to date Dylan Yuki (Setsu Yuuki in the Japanese versions), her crush. A love fairy named Mirmo (Mirumo) appears. At first she was afraid of him but later understood that he was a muglox. Katie soon finds out that Mirmo prefers eating chocolate and creating mischief over helping Katie.
It turns out Mirmo is prince of the muglox world. Horrified at the prospect of having to marry Rima (Rirumu), his princess bride-to-be, Mirmo escaped the muglox world. Hot on his heels, however, are Rima, Yatch (Yashichi) the bounty hunter, Murumo (Mirmo's brother), and many other muglox as well.
