Fukai ni Nemuru Oujo no Abaddon The Animation

Fukai ni Nemuru Oujo no Abaddon The Animation (Sleeping Princess of Abaddon in a Rotten World) is an ONA by Peak Hunt. I watched this way back when it came out in early 2020, but held off on writing a review because I expected that more episodes would be released. However, considering it has been two years of absolutely nothing, I think it's safe to say that this anime has been cancelled. Which is unfortunate, because I was actually quite looking forward to what this studio had in store.

Unlike most other hentai, this particular ONA actually has a story worth talking about. ... In fact, this anime places so much emphasis on the story, that it actually gets more attention than the sexual scenes (of which there are only three). The story concerns a group of six people who become trapped in a haunted mansion while looking for a professor who disappeared while investigating it. Like in all horror stories they foolishly split up and shenanigans ensue. I actually quite like this haunted mansion scenario, since it require the writers to develop a singular location, and the characters all being stuck there creates an uneasy familiarity. One small gripe I do have however is that there seems to be no rules for the mansion, and scary stuff just happens whenever, although I suppose it could also be argued that this sort of randomness is a good thing for keeping the audience on their toes.

The characters in this story are also actually memorable enough for me to bother naming them. The main character of this anime is Homaru, and he mostly just moves the plot forward. He has a friend named Kippei, who joins a guy named Seijirou and a girl named Rikana to search part of the mansion. These three characters do petty much nothing in the story, and I suspect the writers were saving them for another episode which never came to fruition. That leaves the real stars of this anime, Mia and Yachika. Mia is a sweet innocent girl who seems to be in love with Homaru, while Yachika is an aggressive and jealous girl who is madly in love with Mia. I actually felt invested enough in the characters to root for Yachika, and she has some of the best moments in this anime.

Much like the story, the art and animation are fairly solid. The art style for this anime seems to be more reminiscent of a non-hentai anime, which I think actually works really well. It does however still look a little rough at certain points, and you can tell that the animation is struggling to stay fluid. The background art and the character designs are probably the best elements overall. Also, this anime has several gore-heavy scenes, that look a little simplistic and could have used some variety, instead of the wave-like gushes of blood that are frequently used. Lastly, while I usually don't do this, I do want to comment briefly on the sex scenes. There are three in total, but they are very short and two of them are quite frankly worthless. Only one scene (a yuri scene in particular), has any relevance to the story, and it is thankfully very sweet.

The sound design is also good. The voice acting is perfectly satisfactory, but is otherwise nothing to ride home about. The music on the other hand, while not rich in variety, is still very good. Not only is it pleasantly played, but it also contributes greatly to the mysterious atmosphere being portrayed.

Overall, I enjoyed Fukai ni Nemuru Oujo Abaddon quite a bit. It was a nice change of pace, and it reminds me in some ways of older eras of hentai. I only wish there were more episodes to truly test it's strengths. 7.5/10

I would definitely recommend this anime to any hentai fans, although be aware that it sadly lacks an ending. Who knows, perhaps if enough people enjoy it we will get a proper conclusion some day?
