Karen Kohiruimaki always felt out of place in the real world. Due to her extreme height, she found it hard to make friends with other girls her age. Everything changes when she's introduced to VR and Gun Gale Online. In GGO, Karen is free to play the cute, chibi avatar of her dreams! Can Karen find friendship in this bullet-ridden MMO...?

Karen is living her best life, getting to play as her cute chibi avatar Llenn in the VR game Gun Gale Online. She becomes fast friends with mysterious woman Pitohui, who invites her to an in-game event called the Squad Jam. But Karen won't be teamed up with her new friend-instead she gets paired with the stern and silent M. Not 10 minutes into the event, they get surrounded by a hail of gunfire! Will they be able to hold their own as a two-man team against squads with actual military training...? Hey, wasn't this supposed to be just a game?!

Though the official announcement of the second Squad Jam has come out, Karen Kohiruimaki barely shows any interest at all, despite being the champion of the first ferocious battle royale. Or at least, that was true right up to the moment she receives a cryptic message from a creepy stalker who informs her that on the night of the next Squad Jam, someone will die. Now, LLENN needs to take up arms and cut through her inexplicable anguish to prevent her worst fears from coming true!

After a surprise attack leaves the pink chibi Llenn and her trusty partner, M, scrambling, the pair flee to the wasteland. Once fully healed, the two devise a strategy to eliminate their trigger-happy pursuers and seize the Squad Jam victory. With only a minute until the next scan, Llenn decides to bet on luck to overcome the unknown dangers ahead...the first of which is none other than her buddy M?!

A BRAND-NEW BATTLEFIELD AWAITS! ​Just a week after the ferocious Squad Jam 4, Llenn and LPFM face a devastating new challenge—with SHINC at their side! In a drastic departure from GGO’s usual player versus player tournaments, the latest event, The Five Ordeals, is all about fending off deadly computer-controlled enemies. That doesn’t mean the competition is any less fierce, though; the squad that clears the quest the fastest will come away with loot up to their eyeballs. But when the LPFM-SHINC alliance takes to the battleground, the first thing they encounter is…a talking dog?!

A brand-new battlefield awaits! One month after the third Squad Jam, Karen Kohiruimaki is starting to consider her options outside of GGO...but fate won't let that happen! Out of the blue, past prizewinning SJ teams receive invitations to playtest a GGO game mode with an all-new objective: capture a base defended by hyperadvanced AI NPCs. As Llenn reluctantly agrees to participate in the hopes of fulfilling her promise of a rematch with SHINC, she can't help but wonder: Just how challenging can these AI NPCs possibly be?

A brand-new battlefield awaits! As the third Squad Jam begins to wind down, the special rule takes effect. One player from each group is chosen to become a part of the new Team Betrayers and fight against their friends! LPFM-one of the favorites to win it all-has lost a crucial member, and Pitohui couldn't be happier to have been picked. Not looking forward to her rematch with the trigger-happy lunatic, Llenn is forced to watch as Pito gets escorted to the mysterious Unknown area at the center of the sinking map, which is surrounded by a thick fog. As bullets of betrayal fly past former allies, the fog finally clears to reveal...a luxury cruise ship?!
