Monster no Goshujin-sama (Novel)

So, get this – one day, all the kids in a high school get zapped into a whole new world! And guess what? Some of them come out of it with super cool powers. They split into two groups: the Stay Home Group for the power-less peeps, and the Exploration Group for those with powers. But uh-oh, when most of the Exploration Group is out exploring, things take a dark turn. The ones left behind start attacking and harming the Stay Home Group. Yikes!
