Plot
Season 1
The fairy protagonist is a love fairy named Mirmo (Mirumo in the Japanese version). Katie Minami (Kaede Minami in the Japanese version) is the human protagonist and a cheerful and energetic eighth-grader who is shy around her male classmates, which makes 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 Kaede follows the directions and announces her wish to date Dylan Yuki (Setsu Yuuki in the Japanese version), her crush. Mirmo arrives. At first, she is afraid of him but later understands that he is a muglox. Kaede soon finds out that Mirmo prefers eating chocolate and creating mischief over helping Katie.
Mirumo is a prince of the muglox world. Horrified at the prospect of having to marry Rima (Rirumu in the Japanese version), his princess bride-to-be, Mirmo escaped the muglox world. Hot on his heels, however, are Rima, Yatch (Yashichi in the Japanese version) the bounty hunter, Mulu (Murumo; Mirmo's brother), and many other muglox as well. The villains of the first season are the Warumo gang, a gang of criminals who plan to overthrow the Marumo kingdom. Though they are villains, they actually aren't evil; they just pull childish pranks and faint after hearing an evil plan. At the end of the season, Akumi gives Warumo Gang a time sphere, which they play around with and accidentally smash, causing the muglox world to freeze. Mirmo, Mulu, Rima, Yatch and their partners save the muglox world by having the fairies dance in front of a magical door (which allows it to open) and having the partners find the magic time bird which flew into the door to escape being captured by them.
Season 2
In this season, a new transfer student named Saori comes to Katie's school. The villain Darkman, created by the darkness in human hearts, tries to resurrect himself. He influences the minds of Akumi and the Warumo gang. Session magic is introduced for two-person magic, with each person combo producing different magic. Darkman controls Saori and uses her flute to control peoples' emotions. He is then defeated by Golden Mirmo, the outcome of three person session magic. With the help of Nezumi/Rato, he is resurrected until the muglox's four-person session magic gives Saori the power to defeat Darkman. The two worlds are separated until reunited by the muglox and their partners' friendship. Saori goes to Germany to study music with Akumi as her new partner.
Season 3
In this season, a robot octopus, Tako, convinces the gang to look for the legendary seven crystals which are drawn out by different emotions. After all are collected, the gang faces seven trials. Mirmo must pass these tests for the crystals to unite and form a pendant. Tako steals it to save his girlfriend and his land. In the end, they succeed and Tako becomes king of crystal land.
