SCHOOL-LIVE!

Why would anyone form a School Living Club? Could four girls, their advisor, and a puppy really love their school so much that they’d want to live in it? Or is there another reason, something that lurks behind the façade of their comfortable existence? Something that waits outside their school’s doors. Something that has already robbed one girl of her sanity? While the others try to come to grips with a dark new reality, the rest of the world falls to ruin at the hands of a ravenous force, and insanity may be the last hope for survival. Shocks, heartbreak and stunning revelations await as the twisted tale unfolds. (Source: Sentai Filmworks) — Description from AniList community (anilist.co).
