From Yen Press:
Meet the members of the School Living Club! There's the shovel-loving(?) Kurumi Ebisuzawa, the big-sister figure Yuuri Wakasa, club advisor Megumi Sakura, and last but not least, the ever-optimistic Yuki Takeya. The School Living Club is just your average after-school organization where the girls hang out, have fun...and live at school as the sole survivors of a zombie apocalypse. NBD.
