Jirou is a member of the Warumo Gang. He was a millionaire celebrity before joining the Warumo Gang. He is considered the brains of the group.

Kaede is a cheerful and energetic eighth grader. When it comes to boys, however, she is hopelessly shy. 
One day, on her way home from school, Kaede walks into a mysterious shop and buys a colorful cocoa mug. When she reaches 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 Yuuki, the class heartthrob. Suddenly, the adorable blue Mirumo appears! We soon find out, however, that this cute little muglox would rather eat chocolate and create mischief than help Kaede. 
Mirumo, it seems, is prince of the muglox world. Horrified at the prospect of having to marry Rirumu, his princess bride-to-be, Mirumo has escaped the muglox world. Hot on his heels, however, are Rirumu, Yashichi the bounty hunter, and a cast of hundreds of muglox ranging from the good to the bad to the nutty. This gang of adorable troublemakers will see to it that school life for Kaede and her friends is never the same...

One day, Kaede and Milmo met a strange creature. It was not a human or a fairly, but it was Tacos, an octopus-type robot. He said, I'm looking for the seven crystals dispersed in human and fairly worlds. I've been looking for them all over the world, and I finally found they were around here. But I got tired... Will you help me search for them? This is between us, but if you collect all the seven crystals, they will grant you any wish. 
Because it was too absurd, they wouldn't listen to him. But he was eagerly to ask them, and Kaede and Milmo decided to look for the crystals for him. Tacos turned her fairly call into a fairly call crystal in return. Fairly call crystal has a function to detect a crystal, and it can cast a session magic by combining their forces. 
What is the real purpose of Tacos? What is the true role of the crystal?
