School-Live!

School-Live! (がっこうぐらし！) is a 2012 manga about a group of high-school girls doing cute things in high school... or that's at least what one of them sees.

An apocalyptic zombie plague has spread over a city in Japan, and a small group of survivors try to survive inside their school. Yuki Takeya, one of these survivors, has suffered a mental breakdown and imagines her life like if everything was still normal, down to seeing people that are definitely dead and/or zombified. The manga follows her and her friends' almost hopeless struggle for survival.

The manga was written by Norimitsu Kaihou and illustrated by Sadoru Chiba. It was published in Japan in Houbunsha Manga Time Kirara Forward, and has been released in North America by Yen Press and in Poland by Waneko.

A twelve-episode anime adaptation was made in 2015; this has been released in North America by Sentai Filmworks.

Tropes used in School-Live! include:

Break the Cutie: Yuki's inability to deal with the desperate situation she's in puts her inside a imaginary world of her own while chaos surrounds her.
Cargo Ship: In-universe, Yuki asks Kurumi why she don't marries her favourite weapon, a shovel.
Curtains Match the Window: Yuki's hair and eye colour is pink.
Fan Service: We get to see young girls in panties sometimes.
Fingerless Gloves: Kurumi uses this kind of gloves and is pretty badass.
Rose-Haired Girl: Yuki has light pink hair and is a very cheerful girl.
Posthumous Character: It's pretty obvious from the first time the audience actually sees her that Megu-nee is already dead and is a part of Yuki's delusions, since nobody else can touch her and other than Yuki the group seems to ignore her.
Supporting Protagonist: Thanks to her condition, Yuki can't help the group in fighting the undead or getting resources, but the manga mostly follows her POV of things.
The Ophelia: Yuki certainly isn't very sane, and is also very cute.
Zettai Ryouiki: Yuuri Rikasa has a class A one.
