Apocalypse Survival: From the Start, I Get a Sweet Girl

On a sunny afternoon, Ling Yun has just woken up from his nap when he discovers that the campus has been turned upside down. The whole place is in ruins, and man-eating monsters are rampaging freely across it.

As if that weren't enough, his friend's sister turns out to be a yandere. And somehow, she's the one who awakens this trait in him?
