alphinaud's would be hina, alisaie would def be a mokou/marisa fan, yshtola i think... sakuya or maybe one of the mages like alice? yukari or eirin too (one of the Elder Ladies Council), urianger definitely likes one of the buddhists - maybe ichirin or byakuren, patchouli too of course, he might be the rare rinnosuke fan. thancred.............im not sure. maybe kasen, or reimu. g'raha tia Definitely marisa. estinien would be a reisen fan.
minfilia i feel would like sanae and byakuren as well. lyse/yda im leaning towards mamizou.. or shou. papalymo... idk. guy was there for like five minutes sorry
havent gotten to zero yet but Ryne (im counting her as a scion because i love her dearly)........ hmmm......!!!!!! fuck everything. Kogasa. or waka.
