Fifteen-year-old Yuna would rather stay home and obsessively play her favorite VRMMO than do anything else, including attending school. When a peculiar new update grants her a unique bear outfit equipped with overpowered abilities, Yuna is conflicted: the suit is unbearably cute, yet too embarrassing to wear in-game. However, she is suddenly transported into the game's world, where she must face real monsters and magic, and the bear suit turns out to be her best weapon!
