Squad Jam will be held on Gun Gale Online's Japanese server. LLENN wants to participate, but her favorite artist has a concert the same day. But when she can't get a ticket, she joins the tournament. She and her new partner, M head for the battlefield.

Almost one hour has passed since the team battle royale, Squad Jam, began. LLENN and M are still going strong on the battlefield. Being in a favorable situation, LLENN lowers her guard, which is when an enemy team launches a surprise attack.

The second Squad Jam has begun. LLENN and Fukaziroh’s starting point is the most northwestern area on the map. LLENN looks for Pitohui and M, but their location is far, far away. LLENN and Fukaziroh begin their advance towards Pito’s team, PM4.

The climax of the second Squad Jam begins. With the defeated rival team members and the audience watching, the confrontation between Llenn, Pitohui and M starts.
