Karen Kohiruimaki’s college life in Tokyo hasn’t been as she had hoped, due to her insecurity about her height. She comes across Gun Gale Online and, as LLENN, she becomes known as a “player killer.” But then, another female player aims a gun at her…

The second Squad Jam is about to take place. This time, Karen’s friend Miyu Shinohara will participate as well. She converts her character from another VRMMORPG and starts Gun Gale Online as Fukaziroh. LLENN takes her to go buy weapons...

The teams that have come together to defeat Pitohui’s team, PM4, begin their attack. Meanwhile, LLENN and Fukaziroh head to PM4’s current position. They take the shortest route through the dome before them, but realize there are three enemy teams inside.

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.
