I think Mashima only mentioned "She's Erza" and "Natsu and Asuka". Makes me wonder if this is the Connells arc i talk about when i read both the Omakes. The character Mashima introduced kinda look like how Bisca was before she joined FT, maybe she is part of a group Bisca previously was affiliated with and for some reason they came to try and recruit Bisca to their side for a task like assassination since Bisca is the only skillful sniper they know of.
