So how did Akira end up seeing this state of the empire? Simple, he ended up in peeping in some cut, causing him to be transported to Tube after he reported his teammates about hearing underground screams. Since this is an Akira focused episode, it is no surprise that it will feature a lot of great out of suit fights. Even if you pause the scene and watch this episode frame by frame, you can barely see any stunt doubles doing the stunts for the actor. With that in mind, I salute Akira's actor for doing his own stunts.
The biggest surprise is not Akira's reaction about it being heartless, but it is coming from Prince Igam who saw this project for the first time. Even though he is a member of the royal family, he is not aware of what is happening to the empire he is serving. His reaction made me realize that the empire is quite big that even Igam himself might not be aware about other stuff related to the empire. Also, his reaction about Emperor Zeba being quite heartless is kinda priceless.
After seeing some more great fight scenes courtesy of Akira being awesome as always, the kids, to be more specific, Mirai is trying to convince the other working class citizens to leave the empire with them. The reaction of the citizens is something I already expected; they are persecuted by their masters and have no guts to escape from them. The sad part about it is that their parents, who are supposed to support them don't want to escape with their kids! If I consider Tube's resources from the previous episodes, they can easily find them and kill them. It didn't help that they are wearing slave clothes.
Back to Akira, their exit in the underground world is now destroyed thanks to Oyobu and friends. Now that they have no means of escape, Akira has no choice but to fight them, that is until his teammates arrived just in time. Just like Akira, they arrived the same way like he did. After seeing a couple more of those great out of suit action scenes, Takeru finally figured out what Commander Sugata is trying to say about the light and him playing with the strings. After throwing the string to Akira and applying his Aura Power in it as Blue Mask, the string transformed into a rope ladder that they used to escape the underground world.
After defeating the MOTW who is basically responsible in transporting humans who peeped in the crevice of one rock to the underground empire, it is time for the giant fight. The giant fight in this episode is interesting. It's interesting in a sense that that the Great Five didn't start with punching the MOTW, but using the Gyro Cutter as a weapon, something the machine rarely does. After doing some slashes with the Gyro Cutter, they finally finished the MOTW with the finishing move.
