Yuna, a wealthy, socially withdrawn teenager who lives for her favorite VRMMO World Fantasy Online, gets a new bear-costume item with stats far beyond anything else in the game, and finds it mortifying to wear. That embarrassment becomes irrelevant once she's pulled physically into the game world, starting at level one with only the bear suit standing between her and its monsters. She wants an unremarkable life inside this new reality, but the suit's overwhelming strength keeps making that impossible. This light novel is the source for the manga adaptation.
