Wish there was an explanation, not just thrown into the deep end to try and find the answers as we go. Like no explanation on how Orcs appeared, how the entire school and mountain just appeared in another world, or the fact we're just randomly in another world? Granted, the summary told you the "whole school" was transported, but we didn't realize it meant the buildings as well as the people. Normally a series will break this news to you as you read the first chapter, but no you're just tossed in a murky pool of the unknown to learn as we go...
Would have liked a little info, but it's fine... it's gonna def be a harem -_- if there's only been 2 guys we've seen that were alive since chapter 1 even though we don't see the bully again beyond his walkaway before the "earthquake" that apparently was when the entire school, buildings, people, and hill the school was on was shifted to another world.
Poor girls, that's gonna be some trauma hell for them to get past after surviving that hell.
