It's the fifth squad jam and Llen's valued at one hundred million credits. Thrown out into the fog, she's persisted in looking for other participants and finally managed to team up with someone. However, one hour after the start, the outside field starts to crumble until all that's left is a three-kilometer castle. Llen and friends just barely escape the crumble but Pitohui (?) dies from Shirley's(?) exploding ball. The end is nearing, but there's a newly added special rule.??

In the real world, college student Karen Kohiruimaki lived an unhappy life, self-conscious about her considerable height. But inside the VR game Gun Gale Online, her avatar is on the shorter side-just the way she likes it-and each new day brings something exciting! One day, she's invited by her in-game acquaintance Pitohui to join the Squad Jam, a team battle tournament, and after some hesitation, she decides to join, forming a team with M, one of Pito's friends. But when M betrays her, leaving her to fight alone, how will she fare against the final team...?

As the third Squad Jam begins to wind down, the "special rule" takes effect! "Your former comrades are now your enemies." Team LPFM, one of the favorites to win the competition, has been torn apart, and Pitohui couldn't be more delighted! Not looking forward to her rematch with the trigger-happy Pito, Llenn and her new teammates are escorted to the mysterious UNKNOWN area at the center of the sinking map, surrounded by a thick fog. As bullets of betrayal fly past former allies, the fog finally clears to reveal...a luxury cruise ship?!

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!

The Squad Jam is underway, and Llenn and M are already caught in the crossfire! 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?!

The Fifth Squad Jam is underway, and Llenn already has a bounty on her head! But this time, the target on her back is sanctioned by the very rules of the tournament! If she wants to have any hope of victory, she's going to need some allies. But with a one-hundred-million credit reward boosting the chances of betrayal to dizzying heights, she'll have to be extra careful with who she chooses to trust...

A month after the end of the third Squad Jam, a mysterious email is sent to former contestants all across the country. The email contains an invitation to brand-new game, and only the top contenders from the past three Squad Jams are allowed to participate! With objective of capturing bases as opposed to an all-out deathmatch, this new game mode has a completely different feel from Squad Jam. A fitting stage for the long-awaited rematch with SHINC!

After clearing the Five Ordeals, LPFM and SHINC scarcely have a moment to rest before the 5th Squad Jam is announced. And this time around, there's a new rule that's sure to disorient the participants: Players can swap gear with any of their teammates during the match. Naturally, Llenn and her squad resolve to take on the challenge and quickly get to strategizing. But soon they catch wind of an additional stipulation that will stack the odds against them: Whoever takes out Llenn in the tournament will receive a bounty of one hundred million credits!

A week has passed since the climactic 4th Squad Jam came to an end. Llenn and the rest of LPFM join forces with SHINC to take on the mysterious "Five Ordeals," a playerversus-monsters challenge that begins at the stroke of midnight! Yet as Llenn and her friends patrol the area, looking for opponents, the first thing they happen upon is... a cute little talking dog?!

Sparks fly as the fourth Squad Jam barrels towards its pulse-pounding conclusion. But are they the sparks of romance or high-grade explosives? With a marriage on the line, Fire is determined to win by any means necessary, and manages to win SHINC's assistance in overthrowing LPFM. Meanwhile, Llenn's team finally meets up with Boss's crew, but Fire's squad is there and ready to rumble as well! Who will emerge the victor?!

Llenn's stuck between a rock and a hard place! With a pesky marriage proposal on one side and her long-awaited rematch with SHINC on the other, the stakes are higher than ever in this fourth Squad Jam! The battle for first place--and Llenn's heart--continues!

With only two teams remaining in Squad Jam, Karen (a.k.a. Llenn) and M prepare to move in for their final kill...that is, until a sudden barrage of bullets stop them dead in their tracks! Will the two be able to pinpoint the enemy in time for a counterattack?!

"The real-world death of Pitohui." This was the sole motivator that pushed Llenn into entering the second Squad Jam. Accompanied by her best friend and ALO transplant, Fukaziroh, the two overcome wave after wave of enemy for the sake of achieving Llenn's ultimate goal. "In order to save Pitohui's life, I'll kill her myself!" This is no easy feat, however. Pitohui has the strength of a demon with the mentality to match. On top of that, Llenn isn't the only one hunting her! Will Llenn reach Pitohui in time? Or will one of the 79,408 bullets fired in the second Squad Jam beat P-Chan to the punch?!

The fact that Kohiruimaki Karen is 183 centimeters tall has always been something she's felt extremely self-conscious about as an introverted high school girl. But in the world of games, she can be whoever she wants to be! In the popular Gun Gale Online game, she's Ren, a short, all pink, P90 wielding bombshell who's aiming to win the next battle royale!

Old frenemies become staunch allies as the strongest team in the history of Gun Gale is born! This time, LPFM, named for Llenn, Pitohui, Fukaziroh, and M, will enter the third annual Squad Jam and overcome fierce competition and mysterious rules to uncover the mysteries of the UNKNOWN area that lies at the center of the map!
