Love Crumbles: They Want to Love Me to Death with a Single Blow

A younger sister, a childhood friend, classmates, clubmates, and a transfer student. A youthful romance between one boy and five girls, a carefree and cheerful school life, and pleasant times in the club... It's all just a facade. A malevolent god's deception, the world's collapse, a yandere's killing spree, depression and suicide, danger lurking beneath the calm. Is it love that's falling apart, or, at the end of all this destruction... is it still love?
