Yuki Tanaka, a shut-in weeb, gets summoned to another world with the worst skill ever: "Delayed Imitation," which copies weaker versions of other people's powers. The kingdom decides she's useless, kicks her out with no gear, and wishes her luck (aka, certain death.) Teaming up with a knight who pities her, Yuki tries to avoid the Demon King, survive attacks from over-the-top enemies, It's less "epic hero journey" and more "how not to die in a ridiculous fantasy world."
