I read a manga a while back and from what i remember it goes like this: He gets a detention or doing the home room after school cleaning with two girls. They teleport to a new world. The other two girls been there already. Hes a villager. The other two girls are mage and warrior tank. They beat the boss. And must fullfill the quest to get back to normal world. When he upgraded and ranked up he had a chef then they fought a centepide? Thanks a bunch this has been on my mind for months and months now.
