Imawa No Kuni No Alice

Alice Ryouhei will leave high school soon, but he's trying to avoid thinking about his future. Late one night, when he's hanging out with his tough friend Karube and his silly, girl-crazy friend Chota, they see fireworks. After one blindingly bright explosion, they find themselves waking up in a different world. In this 'Borderland,' people are forced to either participate in potentially deadly games or simply die. Will Chota, Karube, and Ryouhei be able to survive this dangerous new world, and is there a way they can get back to their original lives?
