Oh, thanks :)
Its an isekai manga with a black hair (ponytail) female mc, if i remember correctly her whole class got isekai'd (not sure if its the whole class or just a few) i also remembered that she found a teacher in the forest and the fact that she was obsessed with getting stronger ( if i'm not wrong she was trained in close combat)
