Aftkrator have ordered Galopoula to make Border stuck, so Galopoula's Expeditionary Force tries to break into Border HQ to destroy the ship for the expedition. Hyuse goes to meet them secretly in order to go back to his homeland.

Inside the Border HQ, the battles begin: Gatlin and Ratarikov v. 4 strong attackers near the dock, Wen So v. Nasu and Kumagai in a hall. Outside the HQ, the teams struggle with some drones that move like humans. Meanwhile, Jin is surprised that Yotaro follows Hyuse with Raijinmaru.

Border and Galopoula's Expeditionary Force play mind games reading each other's thoughts while fighting. Reghindetz is frustrated that his diversionary plan is not working.

Border fights off the enemy one by one, but Gatlin and Ratarikov have no intention of giving up on completing their mission. Hyuse talks to Reghindetz, and Yotaro finally catches up with him.

About the time Jin brought Hyuse into Border HQ, Tamakoma Second started the match against Katori Unit and Kakizaki Unit. Osamu and Chika support Yuma with their new techniques, and try to create momentum.

Chika starts destroying buildings outside the area where Osamu has set the trap. When Yuma puts Kakizaki Unit in a corner, Kakizaki remembers his past and tries to fight back against Yuma with strong will.

Fumika Teruya prioritizes getting to Chika. Yoko Katori recalls the day her and Hana's fate changed as she fights against Osamu.

The match was over. A party is held at the Tamakoma branch to celebrate their victory, and then Hyuse offers himself to join their team as the second attacker until he arrives in Aftkrator. Tamakoma Second accepts his proposal and Osamu begins negotiation with the higher-ups of Border.

Osamu negotiates with higher-ups to get permission to include Hyuse in his team. Instead of allowing it, Commander Kido tells them that he is going to let Chika join the expedition force, regardless of their rank in the rank battles.

Tamakoma Second fights in a match against Oji Unit and Ikoma Unit. They have only three matches left, and need to be in the top two. Meanwhile, Hyuse attends the Border enlistment ceremony.

Yuma, Oji and Ikoma fight each other fiercely while the battle between the snipers comes to an end. Later, Hyuse shows Border agents that he is highly skilled in the use of sword to be considered a rookie.
