Youkai Ningen Bem

So you also like Universal Monsters and anime with that retro feeling? Then here is something for you!
I finally managed to watch this show many years after hearing about it for the first time - the opening song is just amazing is what first made me interesting, it's somehow really catchy!
I have now seen all 26 episodes. However, I could only find the show in Jap., no subtitles.
The story focuses on three youkai that can transform intro even more youkai. No matter which of the forms, they are the good guys and all they want is to helt humans in need.
The show is from ... 1968 and the animation style is anything you could expect from that era, with irregular animation and lack of fluidity etc. So no, the animation if not the top notch, but at least it's very, very charming!
The visuals make it the perfect show to have on in the background in October and during your Halloween party, with some quite disturbing/ scary visuals, already at the very end of the first episode!
I don't get what kind of world our youkai protagonist are supposed to live in, sometimes they are in present (1968) day Japan with Tokyo Tower and all, but most of the time it's some kind of medieval looking post-apocalypse European desert scenery, but I accept it and I like it.
I kept waiting for the first longer story arc to begin... but it never happened. In each episode, they end up in a new random adventures and meet cool looking side characters.
Ep 6 felt extra dark with Satan worshipping and chopped-off chicken heads And the show's cheerful ending theme made me laugh out loud, such a contrast!
The following episode, no 7, is one of the more memoroable ones, an episode that after a slow beginning becomes pirate themed!
A favourite episode of mine was ep 14 where the kid youkai gets tricked by a slightly older girl to go into a haunted forrest.
I could also recommend ep 12 (the one with the mermaid) och ep 13 (the one where a skeleton army takes human as slaves).
Actually, the only episode I disliked was the a-bit-too-Scooby-Doo-esque ep 17, even though even that episode started out quite promising!
The last few ep tended to be a bit less interesting for some reason.
But... I had actually hoped the story itself to be even more "weird", like a another "Chargeman Ken" I could laugh at. But Youkai Ningen is way... WAY too good for that!
