Fifteen-year-old Yuna prefers staying home and obsessively playing her favorite VRMMO to doing anything else, including going to school. When a strange new update gives her a one-of-a-kind bear outfit that comes with overpowered abilities, Yuna is torn: the outfit is unbearably cute, but too embarrassing to wear in-game. But then she suddenly finds herself transported into the world of the game, facing down monsters and magic for real, and the bear suit becomes the best weapon she has!
Natsuki Subaru, an ordinary high school student, is on his way home from the convenience store when he finds himself transported to another world. As he's lost and confused in a new world where he doesn't even know left from right, the only person to reach out to him was a beautiful girl with silver hair. Determined to repay her somehow for saving him from his own despair, Subaru agrees to help the girl find something she's looking for.
While the perfect getaway for most girls her age might be a fancy vacation with their loved ones, Rin Shima's ideal way of spending her days off is camping alone at the base of Mount Fuji. From pitching her tent to gathering firewood, she has always done everything by herself, and has no plans of leaving her little solitary world.
However, what starts off as one of Rin's usual camping sessions somehow ends up as a surprise get-together for two when the lost Nadeshiko Kagamihara is forced to take refuge at her campsite. Originally intending to see the picturesque view of Mount Fuji for herself, Nadeshiko's plans are disrupted when she ends up falling asleep partway to her destination. Alone and with no other choice, she seeks help from the only other person nearby. Despite their hasty introductions, the two girls nevertheless enjoy the chilly night together, eating ramen and conversing while the campfire keeps them warm. And even after Nadeshiko's sister finally picks her up later that night, both girls silently ponder the possibility of another camping trip together.
