[Frontier]

What's the next step in the Troopers' journey to be able to use the Armor of the Supreme Emperor? Why, mastering their Supreme Arts of course! And luckily Kaito memorized their attack names.

But before the team can focus on that, they have to address a traitor in their midst...Nasti!? Who has been working with Ramaga this whole time!? In her desperation to get Ryo and her boys back, she stayed in contact with Ramaga and even sold out Shion and Ryusei's team to fulfill Ramaga's objective of weakening the Sword of Domination. But just like the mirror and sword have corrupted others, so did the amulet on Nasti. How else could she keep going along with Ramaga after seeing all the people who have been killed in the process?

10 Warriors shower scene! Even if it's a tense conversation among the warriors as they recognize that Ramaga is going to sacrifice the rest of the last-namers, Kakei and Mochizuki, who are the only ones left to be former humans consigned to become demons for their crimes.

Just shouting out attack names isn't going to help them master their Supreme Arts, especially when team morale is so low. Shion especially just isn't feeling it, especially when Gai tells him he saw what really happened to his and Ryusei's team: Shion, so consumed by the Sword of Domination, ACTUALLY KILLED HIS TEAM. Poor guy.

Well, points to Kakei and Mochizuki for putting up a fight rather than get sacrificed...even if Ramaga just fuses them together into one giant monster to fight the Troopers anyways.

Nasti is obviously compromised so that leaves Mirei in charge! Even if no one other than Yamato takes her seriously! But she wants her boys to make it back safely!

If it's not the Kakei/Mochizuki fusion, it's having to battle Shion's original team now revived as zombies, and he can't bear to fight them...so Gai will slay them for him. He's not about to lose one of his own teammates, even if that also means making Shion kill him if the Sword of Domination makes him go crazy.

RIP Kakei and Mochizuki. To the bitter end you tried to protect the rest of your 10 Braves from suffering for Ramaga's plans.

Shion isn't about to lose another teammate, or kill them, so he uses his teams' armors to protect himself enough to save Gai! Cue triumphant fist bump!

Oh no, is Sasuske about to kidnap Mirei? Her Heroine status betrayed her! They even actually use footage for the next episode preview for once!
