Lukatastrophe?

Konata is a total fangirl of the Vocaloid Megurine Luka, and Kagami, Konata's real girlfriend, feels a bit neglected by this. What happens when Kagami by-chance ends up running into THE Megurine Luka, and not only that, Luka wants Kagami to be her master! Miku and Teto will also come in eventually. Eventual yuri. Extremely random idea just popped in my head one day.
