It was just a normal day at Fairy Tail... that is until a little girl is carried in claiming to be Lucy's daughter. The only thing she remembers about her Father is that he's strong and has a fairy on his body, that narrows it down to every male in Fairy Tail... hold on she said strong, maybe about half the males then. What's Fairy Tail to do now?

The Fairy Tail mages are in a predicament! On the other hand, some Sabertooth mages are off to Magnolia on a job to...babysit some mages? Who are they babysitting? Why does this spell trouble all over?
