The title is already a spoiler, and a lot of spoilers are there.
You know WALKING DEAD, the drama or comic. Many zombies all over the world, and people strugle to fight to live. All elements that it has attract us. If watching it, we are forced to think about “Can I live in the world where many zombies are around” “Where should I move to live safer?” “How do I get foods, weapons, materials?”
States is good at making dramas which is expressing the real world.
While in Japan, THIS.
The anime official site says to this anime
“Threre are four students living in the school as a “School–Live Club.”
Yuki; the life and soul of the club.
Though many ploblems, living with friends is much fun. “School-Live club” is working cheerfully every day.”

Kurumi killed her lover having tuerned to zombie, with a shovel . Ri-san is worrying about her little sister, and got sick. Mi-kun is a survivor who lived in a shopping-mall in a few weeks, and her only friend had gone somewhere. Megu-ne has also died, and she is living in only Yuki's imagination. All of them have problems. But facilities which their school has makes them alive. You can find that the explanation above is never saying about Megu-ne.
The anime is little difference from original manga. Manga is drowing more horrible things than anime.
