S01E01 Beginning
Yuki, Kurumi, Rii-san and Mi-kun are the happy members of the School Life Club. Their goal is to be in touch with the many things that one couldn't be exposed to if they'd only been...
A swim in the rooftop "lake" leaves Taromaru covered in nasty green algae, leaving Yuki to give him a bath and the rest of the club to take care of her equally dirty laundry. As the four stand under the sun watching the clothes dry, the conversation turns to "graduation" and their plans for the future. Later that night, a bout of insomnia leads Mii-kun and Rii-san to search for the lock to Megu-nee's secret key.
Yuki Takeya, Kurumi Ebisuzawa, Yuri Wakasa, and Miki Naoki decide to stay over at school. Along with the school adviser Megumi Sakura, they suddenly find themselves to be the final survivors of a zombie attack, and continue to live and survive at the school.
