Takeya Yuki is in love with the school. For her, it's a wonderful place, where she enjoys her school activities, especially the activities of her club: School Life Club. The club has Rii-chan as the president, Kurumi-chan as another member, and the teacher, Megu-nee, always there for them. Yes, she is in love with her school. What follows is the adventures of their club, as they live on the school grounds and mooch off from its services for as long as possible!
... Yeah, right.
Unfortunately, the truth about the situation she and her friends are currently in is much less colorful and far more bleaker than Yuki can ever imagine. The beautiful school she enjoys so much is in reality in ruins, the School Life Club is more or less barricaded in a section of their school, and she and her friends Rii and Kurumi are the only living people likely left in a city that is overrun with zombies. Despite this, her friends try to let Yuki live as close to a normal school life as they could manage, and through these efforts find it within themselves to live, and not merely exist day-by-day in the hellish situation they're in.
Also known as School-Live!, Gakkou Gurashi! is what you get when you cross together some of the most unlikeliest of genres: Schoolgirl Series Slice of Life, and Zombie Apocalypse Survival Horror. Drawn by Chiba Sadoru and written by Kaihou Norimitsu of Nitro+ fame, and serialized in Manga Time Kirara Forward (which serialized, among other series, Puella Magi Kazumi Magica and Yumekui Merry), this story explores what exactly happens when the cute girls you'd normally find in the former get dumped into the setting of the latter.
