It's Spring break for Karen, and as she returns from her hometown back to Tokyo, she gets a very unexpected guest.

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...

LLENN receives some unexpected help during her battle in the dome that results in a change of tactics as she continues towards team PM4. M is surprised to see team SHINC approaching, and Pitohui learns that her ruthlessness can have consequences.

At last, it’s the finale of the Second Squad Jam. LLENN and Pitohui’s one-on-one combat has begun. How will their fight end? Who will win the Second Squad Jam? And will LLENN be able to save Pitohui’s life?

Three months after LLENN won second place in the team battle, “Second Squad Jam” (SJ2), “Third Squad Jam” (SJ3), was announced. Soon after, news broke out that Pitohui, M, Fukaziroh, and LLENN formed “LPFM,” considered the strongest team in the game. Clarence is obsessed with LLENN, and Shirley ignites her fighting spirit to kill Pitohui. All members of SHINC hope to take revenge as they lost to LLENN in SJ1. A heated battle surpassing SJ2 is about to begin…!

The organizing team of the game announced a shocking, special rule to be implemented. One “betrayer” will be selected from the six remaining teams to form a new team. Pitohui is selected from LPFM, and the team leader of SHINC, Eva, also joins. With this new rule implemented, Pitohui is happy that she can fight against LLENN. Eva gracefully leaves her team, hoping to fight against LLENN, too. All of the "betrayers" meet up on a luxury cruise ship set up in UNKNOWN, forming a most intimidating team named "BTRY"!
