がっこうぐらし! [Gakkō Gurashi!]

Following a group of high school girls who live at their school, this manga from Houbunsha (2012–2020) slowly peels back a cheerful surface to reveal a world overrun by the undead. Writer Norimitsu Kaihō and artist Sadoru Chiba craft a poignant genre blend, contrasting slice-of-life warmth with survival horror. Its twelve-issue run is notable for its emotional depth and the way it subverts expectations, making it a quietly influential work in the school-life horror subgenre.
