Character's and OTP's

In the guild called Fairy tail four new members joined in and their names were Lilac,Luna,Carlos and Luke.They were all dragon slayers and they each have exeeds
But as time went by Mirajane found some new OTP's to help out so she called her friends for help to put together a plan.
(you will find out the OTP'S later as well)
Will Mirajane succeed in her plan....or will her plan be disrupted?
I do not own Fairy Tail, Hiro Mashima does
