Re: Stuff similar to Urotsukidoji - Legend of the Overfiend
Heh, this brings me back... 20+ years back, when tentacle rape/monster porn were in their heyday.
First, I'd recommend more anime based on Toshio Maeda's works* (he's the author of the Urotsukidoji manga). These include, by approximate order of interest:
-Demon Beast Invasion (similar to Urotsukidoji in tone, but more sci-fi-ish, at the start anyway; exactly what it says on the tin otherwise. Pretty gory, but I doubt you mind)
-La Blue Girl (more comedic, sex-ninjas VS sex demons, gore usually limited to monsters)
-Adventure Kid (often said to be a companion piece to Urotsukidoji; rather confusing plot, involving alternate dimensions and time-travel because Evil Nazi Computer; haven't seen myself, may not contain actual tentacles but probably has a scene or two)
-Nightmare Campus (kinda a ripoff of the earlier arcs of Urotsukidoji, which is funny due it being self-ripoff; seen at least the first ep but I don't remember much)
-Demon Warrior Kouji (haven't seen it or heard much about it, but it is by the same dude)
*Note: This is mostly very old stuff, late '90's at the latest, and often even has an '80's-ish vibe. OP likely will consider it either a non-factor or a bonus, but caveat emptor for others who may find the style jarring. Also, plots are often confusing, bordering on the nonsensical and sometimes even ending up contradicting themselves; but let's face it, it's probably not your main incentive to watch
Gotta go, but next I'll try and cover similar stuff that isn't from Maeda. Kinda an amateur semi-expert on that stuff.
