Having immersed herself in the VRMMO World Fantasy Online for nearly a year, the reclusive yet affluent 15-year-old Yuna is surprised when the game administrators gift her a bear costume. Despite its initial awkwardness, the costume proves to be a game-changer, enhancing her character's abilities significantly. Upon donning the bear outfit, Yuna is unexpectedly whisked away to a different in-game realm, cut off from reality. Lost and unable to log out, she embarks on a journey to navigate this unknown territory. After saving a girl named Fina from savage wolves, Yuna is led to the bustling city of Crimonia. Despite drawing attention with her peculiar bear garb, Yuna's combat prowess and unique appearance earn her the moniker 'Bloody Bear' as her fame spreads. Undaunted by the sudden turn of events, Yuna embraces her new identity as an adventurer, determined to relish every moment in this fantastical world.
