Mirmo de Pon! (2002)

Katie(Kaede) Minami is a cheerful and energetic eighth grader. Katie is shy around her male classmates, so it is difficult for her to date.

One day, on her way home from school, Katie walks into a mysterious shop and buys a blue cocoa mug. When she arrives at home, she casually 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 Kaede follows the directions and announces her wish to date Dylan (Setsu) Yuki, the class heartthrob. 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.

Mirmo, it seems, is prince of the muglox world. Horrified at the prospect of having to marry Rima (Rirumu), his princess bride-to-be, Mirmo has escaped the muglox world. Hot on his heels, however, are Rima, Yatch the bounty hunter, and a cast of hundreds of muglox ranging from good to bad to nutty. The muglox see to it that school life for Katie and her friends is never the same.
