Anyway, after her various misdemeanours during the course of the series so far, I suppose it was only a matter of time before the various factions who have something of a dislike for Kuniko would go out to take her back into their custody, and that's exactly what happens at the very start of this episode. Quite why arresting a teenager needs the use of armoured trains and a veritable army is beyond me, even with Kuniko's abilities in mind, but better to be safe than sorry I suppose. However, this time she doesn't go to jail alone, as her friend Tomoka goes with her after slapping one of the men sent to arrest her - An act she commits for reasons we learn later in the episode, and which relate to Kuniko's last period of incarceration.

While Kuniko is expecting another easy ride in jail, it seems that plenty has changed since her last stay - Not least the frankly bizarre and entirely ridiculous introduction of Lady Ryoko as the prison warder, who I assume must have decided to take some time off being a company president to do some kind of job swap. If that isn't bad enough, Ryoko has obviously been watching too many bad war movies, and spends the entire episode dressed as some kind of Nazi prison warder - Only Shangri-la could do this kind of thing with a straight face.
So, the rest of the episode is all about Kuniko's prison hardships through to a shocking conclusion, while in the meantime her Metal Age friends have decided to rescue her from jail. By digging a tunnel. Using a couple of shovels. Jesus Christ you guys, she's going to be 400 years old by the time you've dug far enough to rescue her! Again, it appears that The Great Escape has been playing entirely too many times on Japanese TV, to the detriment of this series.
Really, I simply don't know what to say about this series beyond Ryoko in a Nazi prison warder uniform and Metal Age digging a tunnel to rescue Kuniko - Two items which could have come straight out of the cheesiest, most stupid Saturay morning cartoons imaginable, and two plot points which make light work of destroying any semblance of serious scripting or portraying the severity of Kuniko's situation. It's almost like this series wants to be some kind of laughing stock, but I fear that the truth is probably a pure and simple lack of imagination of the script writes and animation teams part, and it's really starting to show in a big way, further sacrificing what could have been an interesting series and story to the God of Cheap Stupidity.
