A survival story that's not entirely about survival. The apocalypse arrives, and the whole city mutates. Ling Yu, an ordinary office worker in Nandu, scrapes by in his rented apartment with the help of what he has learned online about surviving the apocalypse and a homemade spear.
One day, a summoning interface from another world pops up on his computer. But the Valkyries he summons, once invincible on the battlefield, are now so hungry they can only eat canned food and instant noodles. The shipgirls who once operated warships can now do little more than organize and repair tools. Faced with hordes of monsters outside the door, these fallen girls can only struggle to survive alongside Ling Yu.
"Ling Yu, I think... I've recovered just a tiny bit of my old power."
"No! Don't go bringing anything terrifying here!"
