RBD-230 - The missing sister is in the Yakuza? A dangerous undercover mission for a dark-side beauty

I've always felt Yua Yoshikawa's films were a mess, but this is the first time I've actually liked her performance. I realized it's because she puts a massive amount of effort into the fellatio scenes. Kazahana is the same—neither her acting nor the actual sex scenes are amazing, but when it comes to fellatio, she uses her upper body muscles flexibly like a spring to swallow the guy's member deep down. Because she's using her physical strength and putting in the effort, the fellatio is worth watching and makes a good impression. The lesbian scene at the end wasn't bad either, likely because the actresses were active, interweaving tongues and rubbing chests. Bound scenes often result in the actresses just lying there like dead fish, so seeing such initiative was a plus. I can't rate it highly as a whole because the other parts were lackluster, but if you're a fan of 'slave-service' fellatio, it's worth a watch for the high quality of those specific scenes.

Yua Yoshikawa's performance is actually pretty good. But Kazahana is a total disaster. She's unattractive, flat-chested, and the tattoos are the worst. Previous entries in the 'Slave' series were generally decent, so this is a disappointment.

I haven't watched every single installment in this 'Slave' series, but this one... feels like a huge miss. As other reviews have noted, it can be polarizing, but beyond that, the acting is just... not good. I didn't feel any sense of pathos at all, which makes me feel like it completely loses the essence that makes this series what it is. The acting is a total failure both as a narrative piece and as an AV.

Compared to the masterpiece '10' featuring the golden duo Yukimi and Mashiro, this is an incredibly boring work. The sister's tattoos and the younger sister's amateur acting completely killed it for me. It's rare to see such a vast difference in quality under the same director. A total failure, especially since 10 was so good.

Incorporating tattoos into the plot is a first for the series, but it's likely to be divisive. Even though it's a 'sister' theme, the older sister isn't broken until the middle, so there's not much interaction between them. The younger sister is handled in the first half and the older in the second, and since the content is identical, it feels repetitive. On the other hand, you could argue it highlights the differences in their appeal.
