Huh, the translation quality's gone down a bit. Some lines need a once-over for grammar, Wiesel becomes Wisel, and "I'm not a stranger" seems like it should be "I'm not someone suspicious, okay?" Because they haven't met, and so are strangers, and to tie in with Reid promoting her from "pretty sus" to "classmate"

Standard fare for an isekai so far. OP characters enter the school, some arrogant brat insists it's a fluke and can't be real but will inevitably have to be put in place. Dorky "fellow country bumpkin", and a teacher with a disregard for normalcy.
But the premise was at least a little novel, and even if it's all very by-the-books, I still am here for the Reid/Elria interactions.
