The Private Kaginado Academy. This is a demon-infested place where the legendary warriors of the world have gathered..., or rather, an utopia where they have squeezed out more tears than the total amount of water in Lake Biwa (estimated) from Key fans around the world for over 20 years. The goal of the Kirahoshi, who couldn't get enough of the fans' tear glands and have finally broken down the walls of the world and gathered together, is to enjoy a new school life in a new world. Free, joyful, and happy in every way. A dreamlike story begins.
