Crystal Shine High School, the most prestigious high school in all of the lands. If you managed to get in, your life is set. The school soon launched an after-school program that urged most club leaders of the school to participate. "Leaders Club." A club in which students of high reputation or with strong titles gather to speak up about the school. Most people were denied, other high reputation students didn't want to deal with an after-school activity, but 12 titled students decided to take this opportunity. The club is a great idea, how could it not be? It's just a bundle of students bonding and sharing memories, nothing can turn south from that, right? Could it be, this story isn't how it seems? (Kind of inspired by, "Another.")
