Erza wasn’t that desperate, thank you very much.
He didn’t see her as an equal in any sense and would only help her if she gave him something in return. Hell would freeze over before Laxus lent her a hand. She had never even properly met Mystogan, let alone knew how to contact the eccentric recluse. Mirajane warned her of how many mages failed to complete the task alone and advised that she should get some help from fellow S class mages. Her task was to eliminate a terrifying monster that had laid siege to a small kingdom for ten years. She had been on an S-rank mission that lasted for four days. It was just the perfect end to her rotten day. It would be her luck that she couldn’t get any shut eye. Sleep for whatever reason decided not to claim her. The scarlet knight had been tossing and turning in her bed for about an hour now. Normally she wasn’t the type to mutter obscenities so freely. Erza may seem a little slutty in this, but I always saw Erza as a bit of a tease in canon. I was going to use Jellal, but decided to shake it up a bit by having Natsu instead.
