RBD-321 - Slave Investigator Side Story: Miho, The Beast's Toy

This work focuses on the victims who are usually just handled via narration in the intro of investigator-themed films, or those who are already 'trained' and just lying around naked (the actresses who are usually credited as 'co-starring: XX' separately from the lead). I've never seen a film where someone stays completely naked with just a collar on for over two hours out of a 190-minute runtime. Content-wise, it's definitely a spin-off of the female investigator series, but the investigator herself never appears... They could have just put some random actress in that ridiculous cat suit. There's gang-bang, deep kissing, no reliance on toys, the heroine isn't fully broken, and the story isn't a total mess, so I gave it 5 stars... though the 190-minute runtime and the bad ending might be polarizing. I personally appreciated those aspects, though lol.

Ashina-san is the best. Being collared, hands tied behind her back, getting creampied and covered in semen—she has such a beautiful body. Seeing a pretty woman turned into an oral slave is top-tier. There are plenty of scenes to jerk off to, so be careful!

In this setting, the Samejima syndicate is as powerful as an American mafia organization, attacking the special investigation unit's headquarters and killing three detectives. It's not an impossible scenario since people often turn themselves in as scapegoats. For AV enthusiasts, the Attackers 'Slave' series, 'Slave Soap,' 'Stage of Slave Colors,' and this series' main focus, 'Sexual Slaves of Beasts,' are must-watches. I plan to collect all three new releases. The training scenes here are very orthodox; they don't leave scars or drug the women, preserving the 'slave's' value. The specific instructions, like telling Miho-chan to 'tighten your vagina' when she's about to climax during the cowgirl position, are a huge draw for fans of the genre. Fans who were disappointed by the lack of training scenes in the 'Slave Island' series will definitely enjoy this one.

There's no sense of the protagonist falling into slavery at all. I expected some tension about the husband showing up to save her, but that never happens. There's no feeling of masochism in her acting lewd in front of her husband, nor any sense of the husband's anguish as his wife is violated right before his eyes. Even the final treatment she receives from her husband is too casual, leaving no sense of despair. As for the acts, while there are some distinct scenes like her being fully naked from the start, doing M-spread masturbation with a dildo, or 69, there are too many repetitive scenes like standard missionary or standing oral sex just with different partners, making the runtime drag on. It's really just a work where you watch the beautiful Miho Ashina from various angles.

*My only impression after watching it was that I was tired. Although the story is simple, the same scenes flow one after the other, and I think the 120-minute duration was enough for the film to be completed. Therefore, I don't feel like I gained anything in terms of cost performance. As several people have pointed out, I think the title character ``The Investigator'' is also strange, and it seems more like a work in which the lead character has fallen into the trap and become a sex slave, rather than one in which he is constantly being exploited. I'll give it an average rating considering the actress's hard work.
