Plot.
The first episode begins during a rainy night in a thunderstorm when Professor Goda is digging under a large tree in the school yard, when he breaks through a mysterious stone tablet he is attacked by a large tentacled monster and is suddenly infected. Later, millions of students are attending the opening ceremony of the Siren Academy's-(a prestigious boarding school for girls) freshmen welcome. It's at this point we discover that two young girls Sayaka and Atsuko are lesbian lovers who have dated and known each other since high school, are trying to hide their affair from Atsuko's older sister who is currently playing the organ. We then see Professor Goda, who is also attending the opening ceremonies, looking on the crowd of freshmen with evil eyes and a sinister smile on his face. After the ceremony has ended, five girls discover a goblin-looking creature in the background of one of their photo's after one of them got her picture taken; however due to its frighting appearance, they decide to get rid of it instead of keeping it.
The scene then shifts to an underground basement in the school's church in which Professor Goda and The Director are raping a freshman student who is tied up and gagged. The Director is dressed up in typical red S&M bondage gear while Goda is buck naked. Goda comments that he needs the extracts of younger women in order to provide food for an organism that he just discovered. The Director appears to be happily enjoying watching the torture and involves herself in the process by whipping the freshman with her riding crop until the freshman faints from shock.
The scene cuts to the dormitory where Sayaka and Atsuko are currently engaging in heavy petting and passionate kissing in their dorm room. The scene develops into a full sex scene until they are interrupted at the end of their lovemaking by a group of fellow students knocking at the door asking them to come to dinner. It's at this point there are clear signs that there is something wrong with the student population as all the girls are listless and uninterested in anything, including Atsuko's "impressions".
Yuko manages to get a little life out of them through her violin playing, but it is clear there is still something wrong. Professor Goda is in the church listening to the music when he is suddenly attacked by what appears to be a fairy, who we later find out is named Rom. The show then cuts to a montage of Sayaka and Atsuko's life at their new school, and Atsuko proves to be an apt athlete in lacrosse and a healthy eater, and is very popular with the other girls in the school, to the disapproval of Sayaka who wants Atsuko all for herself.
Production.
Considered soft porn, "Angel of Darkness"' attempts to merge the magical girl anime formula with the tentacle rape hentai genre. This was done in order to circumvent stringent Japanese censorship laws at the time that did not allow the animation of the pubic region and identifiable genitalia. As such, hentai films began using monsters with phallic tentacles to "rape" women in films.

Reception.
Patrick Drazen regards "Angel of Darkness" as being an example of the use of "horror to express sexual anxiety", and as an example of Gothic fiction. Chris Beveridge regards the hentai to be "neither the best nor the worst" that he had seen, but enjoyed the third episode over the last, as it was more plot-oriented.
