I'd agree. If Mashima did not put a big stonking warning on the last page of the previous chapter that he was going to do two side stories. If you missed that, you only have yourself to blame and lose any rights to bitch.
Olololo..Bitch? Hardly, but considering that the Festival is the main plot I thought Kagura's past and reasons could be considered as "side-story"
