Well this has been sitting on my PC for ages, so I suppose I ought to post it.
This was adapted into the Evil Town OAV, which makes sense as it’s a fairly stand alone arc, I think it only ties into one later arc (Beast King) and that’s only by sharing some characters. Luckily this arc has been scanlated so I can properly tell what’s going on, though ironically this is probably one where it’s least needed.
The character this arc shares with Beast King is Aira Mu, who is the first imported character for this arc. She is from God Mazinger, Go Nagai’s Mazinger flavoured take on Daimajin. The TV version can be considered a failure, getting cancelled before it completed it’s tale. There is however the manga version which is complete, as well as novelisations. Considering what a massive snooze its theme is, the failure of the anime comes as no surprise.
Aila here resembles her manga incarnation, a traditional Nagai heroine rather than the Satoshi Hirayama designed red-headed appearance she had in the anime.
The second imported character is Ricki, the former female pro-wrestler and sidekick/protector of Jiro Shutendo in Shuten-Doji (1976-78). She features in the sections before it goes completely insane with time-slips, spaceships and cyborgs.
Here she is in Violence Jack in one of the rare panels where she isn’t topless pickaxing.
And here she is in Shuten-Doji:
