Takeya Yuki is a cheerful high school girl who highly enjoys her school, which is, to her, a wonderful place. She's a member of the School Life Club, along with Wakasa Yuuri, who serves as club president, Ebisuzawa Kurumi, and Naoki Miki, and her club is, to her, a great source of fun. Yet, her club mates and their club adviser Sakura Megumi aren't having such a great time; after all, their most important duty is letting Yuki safely live out her delusion of tranquility while they are all forced to live confined to a barricaded part of the school building and a zombie outbreak has turned next to everybody else into the undead. — written by Hinoe
