It's a bit boring, I'm afraid. I watched it because it's only three-minute episodes, but even so I found it a bit of a slog. I'd stall with only three episodes left, even though that's only about ten minutes. There's nothing obviously broken about it, but I didn't care about the characters or their adventures.
It's a spin-off of The Irresponsible Captain Tylor from 1993, which I'm not wild about. A bit like this spin-off, actually, it's okay but not something I'd go out of my way to watch. It's lampooning anime like Space Battleship Yamato and Legend of the Galactic Heroes, with a hero who saves the galaxy by being lazy and happy-go-lucky.
This sequel is set centuries later. Both the Holy Raalgon Empire and the United Planets Space Force have disappeared. There's no military at all, in fact, and everyone lives in peace. Banjo Ueki Tylor (presumably a descendant of the original's Justy) is a garbage collector on a siderial mega-structure like a dozen looped Ringworlds. His best friend is a robot called Yamamoto and he's basically relaxed about everything. He'll drift through this story without ever taking the initiative or doing anything you'll remember until the last episode, when he saves the villain. He's nice, but he's forgettable.
He meets Azalyn Goza the 168th, the teenage empress of the Holy Raalgon Empire. I presume that's the character of the same name from the original, perhaps cryogenically frozen or sucked into a time-warp. Azalyn refuses to accept that her empire is gone and tells Tylor that they're going to fly to the centre of the galaxy.
The good news is that there's quite a lot here. Tylor and Azalyn go all over the place, have adventures and meet people. You could expand this into a normal anime series, not just a short-form one. I particularly like the SF worldbuilding, which starts with that Dyson Floral Decoration thing and later gives us an underground drill rocket, a ghost guitarist, a villain, a pirate king with big boobs and a glass castle in a snowy wilderness. They're loading up with so many ideas, in fact, that the last episode can't take it and sinks. Here's a quote.
"That fluid is cleaning the space and time that are flowing out of it. That fluid will become a crystal that returns space and time to normal. The crystallisation effect that controls this space-time is the space-time magic that supports this sidereal megastructure. The space-time current that the real Tylor was caught in, one of the branches in it created Hitoshi Yashioma, you."
I mean... what? That's the kind of dialogue that has you pausing and rewinding, assuming you hadn't been paying attention because you must have missed something in the subtitles.
There's a mysterious being called Voyager that knows about multi-dimensional space-time events. I found myself remembering Doctor Who comic strips. (He also has a guitar.) The villain actually gets a decent amount to do and manages to earn his story role, which is impressive in a short-form serial like this. (Shame we can't say the same of Tylor.) There's plenty here, but I think these ingredients are often being undersold because they're just not getting enough screen time. Take the ghost guitarist in ep.7, for instance. Was he actually a ghost, or was it our first glimpse of Voyager? Dunno. Don't care. That's a spooky throwaway that could easily have been developed into something interesting, but unfortunately you'll be watching something else in three minutes' time and so it lacks impact.
Occasionally there's also questionable content. Cyborg JK the homosexual warrior is an old bloke in a schoolgirl's uniform. Tylor and Azalyn rescue Yamamoto from him and save their friend's chastity! Uh-huh. Ep.4 takes us to a land of busty women who'll strip you naked. I'm not sure that those improved the story.
It doesn't work, I think. There's a mildly amusing gag in ep.9 when Yamamoto's clinging to the outside of the ship, but I didn't laugh because the cast weren't strong enough to make the joke funny. This show has lots of ideas, lots of plot and lots of stuff being thrown at the wall... but its cast is a bit rubbish and I think you'd probably need to have seen (and enjoyed) The Irresponsible Captain Tylor to get anything from them. For me, somehow, it feels both busy and hollow.
