Buttering up NPCs, you say? That sounds like something Yotsuyu would get up to...if that ends up earning Purifeul some Colormarch points, that's just cream!

I think her secondary focus would be studying, though at this moment I am not sure what she'd see as the best magical option to concentrate on. I know her House specialty is Modification, and she'd study Discovery as a "know your enemy (rival, really)" sort of thing. And possibly Sundering, since that's what got her here...
