where'd do you think an american gensokyo au would be set
ngl my au is set in the north midwestern US just because that’s where i live. the town wherein marisa works is based on naperville, illinois. the city where reimu goes to school is based vaguely on lansing, michigan as well as grand rapids. the forest behind marisa’s house is based on the forest behind an ex’s house. the midwest in general is very Strange so that kind of works.
however a sort of american gensokyo would imo be set either in like, the forgotten underground beneath a city, or out in the middle of nowhere in the southwest, probably. something like that at any rate.
