Both are based on reverse harem visual novels.
Heroine starts living in a "different world" full of pretty boys with magical abilities, though in Kamigami no Asobi these abilities are more related with mythology since that's the main theme there, but is very much the same with the heroine discovering a little bit about each characters and about herself every episode.
The boys also seems to have lots of troubles and dark pasts, so the heroine will start to find out about this and help them in the end.
