Ah, a bullet-proof vest. That explains. In any case, the plot has been skyrocketing forward in the past few episodes. Already in the first five minutes of this one, Akai’s cover is blown, and he’s unmasked as a traitor. Hiraga Gennai gives the explanation as to how he managed to survive for more than a hundred years (some kind of immortality-potion?). His meddling also manages to make sure that everyone managed to escape from Torii, who also showed up afterwards. The only casualty is one eye, which gets ripped out by Blue Monster from the Sky.
The rest of the episode focuses on Tetsuju. I’m not sure exactly how it happened, though one of his smaller bear-companions brainwashed him and made him think that the Third Blue Monster from the sky was his Kaguya-hime. Later, we see it dig up a humongous spaceship. I’m not sure where that one came from, actually. Was it the one used by Blue Monster from the Sky to get to earth? Then why was she so interested in Seikichi’s gunpowder?
My favourite character in this episode was yet again Akai. Not only does his secret go out, he’s also accused of cosplaying. And despite the rather cold relationship the two of them have been having for the past episodes, it was really cute to see both Akai and Blue Monster from the Sky together, when they’re both in trouble. Later in the episode, we also see another fight between Akai and Ginjiro, and it was as great as always. ^_^
The thing is that there are still 7 episodes left, while the story could be resolved in two of them. What are the creators planning for a finale? So far, Ooedo Rocket has been definitely entertaining, but nothing extraordinary has happened yet. Could this have been saved for the final episodes? I do hope so!
