If You Won't Back Down, Fight: Let Loose in the Apocalypse

The apocalypse arrives, and resources are running out.

To stay safe with her grandmother in a cellar, an ordinary girl named Liu Sheng ventures alone to a bizarre town of paper offerings in search of supplies.

She barely survives, but when she returns to the cellar, she finds everyone inside dead. Her grandmother is nowhere among the bodies. Beneath the covers, she finds only a note: If you want to save her, come to Peru City!

Along the way, she meets Su Zhi, a girl raised by whales, and Pei Yulu, the head of an orphanage living in the sewers, among others. For the first time in her life, she finds affection from people other than her grandmother, and her world begins to gain color.

Together, they fight against Peru City, unaware that the adventure is only just beginning.

A journey through the universe, and the truth behind the apocalypse.
