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...
What could possibly have possessed Yuki to make her charge into the club room brandishing a deck brush and shouting about cleaning up? The brilliant idea to turn the rooftop lake (a.k.a the water storage tank) into a pool for the day! The girls carefully transfer the lake's fish to buckets, scrub out the algae and pond scum, and let their troubles slip away for the day as they enjoy their new pool.
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.
