Right then, now to get to work on relationship proposals:
There are a lot of characters and I'm lazy, so I decided I'd only make relationship proposals for characters who would be similar enough or different enough. Those who are roughly neutral in the eyes of my characters will be left out for now.
Mayari
@Kythera As two members of the Fight Club, both who have increased strength, I think Medb and Mayari would have a kind of love-hate relationship going on. Each of them is the embodiment of what the other character despises, and I think they would constantly be butting heads trying to beat the other considering Medb's competitive nature.
@PastelChaos
Ebisu: I think Mayari would view Ebisu as one of those cute underclassmen types, despite being in the same year. They have similar enough personalities that I think they'd be on good terms with one another, but she'd secretly find his constant smiling a bit annoying, not to mention naive, so true friendship would probably be impossible.
Erebus: Considering Erebus's abilities, Mayari would view Erebus as somewhat of a training dummy. She'd mainly use him as a means to practice avoiding difficult magic without relying on Eclipse.
@chaosheart13
Nabu: I could see Mayari and Nabu getting along since they both share an appreciation of knowledge.
Hui: I reckon Mayari would have a lot of contempt for Hui, mostly because Hui hates being looked down on Mayari finds it hilarious that she can look down on him both physically as well as mentally.
Aaand now I'm bored of thinking, so I'll do the other ones later.
