Violina, a girl polarized by love and loathing, finds herself thrown into a post-apocalyptic world with mankind on the brink of extinction. Discovering the means to travel back in time, she sets out to save the world by preventing the events leading up to the apocalypse. But as her quest advances, she becomes increasingly disgusted by the evil inherent to humanity and seeks lethal justice against all who wrong her—a list that grows exponentially until it encompasses all of mankind.What was it that gave people the right to live? Was it simply being born? No. Everyone is born to no credit of their own. It’s the choices people make that determine whether they deserve their lives, and by that standard, everyone Violina knew deserved to die—everyone except for Lux.
