In Fairy Tail, does it matter what type of magic two wizards use in order to perform a unison raid? Okay, I understand the Gray and Juvia have done unison raids before, but both of their magics have the same concept just in different forms. But let's say someone like Natsu, or anyone with a type of Lost Magic (dragon slayers) were to perform a unison raid with Mirajane, for example.
Specifically, my friend is writing a fanfiction on Fairy Tail, where the main character is a dragon slayer, and she also has another certain magic that was passed down from her mother, a type of lost magic (a musical magic, where if the character sings or plays any instrument, the sound waves attack the opponent, and because of the whole thing with the
Dragon Slayers with their dragons being inside of them, and making antibodies so they wouldn't turn into dragons, (somehow) turned into her forms that she can use for this lost magic, that's are crazy powerful.
My friend isn't really sure if she can perform a unison raid with Mirajane, because they both sing, because Mira doesn't have this lost magic. So is this possible?
(Sorry if it's really long)
