I have very little to say about Masahiro Shirako's Rain of March: Devilish Delights because the work inspires very little. A side story in the multi-installment Rain of March series, this entry sees teacher Kouta Futagawa and his former student and romantic partner Miyako Ootsuka exploring BDSM influenced intimacy. The big issue with this doujin — outside of Miyako not getting Kouta's express consent for this kind of intercourse, though, is that this is very much a kink-inspired story written for vanilla people.
Hentai is a medium that lends itself well to the exploration of just about any sexual idea or fantasy. A work can depict extreme, ridiculous, or even unethical situations without issue because these are ultimately drawings of cartoon characters meant to elicit an intended response in the reader. A creator can fill a blank page with anything, and there is an almost unlimited amount of inspiration to draw from in the world of kink.
Devilish Delights decides to call it a day with just a blindfold, some (cheap) handcuffs, and some edging play.
I know that to people more vanilla than me, this work might seem daring. I also know that people less sexually explored or adventurous than myself need onramps to this space as well. However, the subject matter that Devilish Delights chooses to focus on feels downright basic to me, and I can't recommend that anyone spend their time or money reading it.
Further queuing me into the boilerplate plot is the equally safe artwork. While perfectly proficient and inoffensive, Miyako feels like a composition of recently popular waifu design aesthetics and feels generic as a result. As far as writing twists and turns go, Kouta breaking out of the handcuffs Miyako placed him in to reassert his dominance in their dynamic felt both overly telegraphed and like a betrayal of what makes a side story like this appealing. Plenty of entries in this work have Kouta topping, and it'd be more fun to have the roles completely reversed throughout this doujin instead of getting a last-minute reinforcement of traditional gender norms.
The best compliment I can give Devilish Delights is that the translation is at least having fun. Chad O. has characters express less common words and phrases like “yipes,” and that variance of understandable language, and seeing these deliberate choices pop up made the work feel more human and less typical. Still, I'm probably going to forget this work exists after I finish this review, and I think anyone who reads it will have it fade from their memory similarly quickly.

I feel like this book was cheating by the time I got to the end of it. For the most part, Rain of March is a short story that follows a couple indulging in a very specific sexual act. The girl in the relationship thinks that her boyfriend is into dominating women and so does everything she can to fulfill that fantasy. However, she teases him to a breaking point, and he ends up flipping the script on her. This happens a lot in these types of stories that will sometimes not fully commit to one particular fetish for the sake of showcasing a bunch in a single scene in order to create a broader appeal. That makes sense, but that is very distracting when literally the impetus for the sex scene in the first place is to explore that very particular fetish. The story tries to make up for that by establishing that a lot of the situation was just one big misunderstanding, so you can understand my frustration a little bit when I say it felt like the book was cheating because that misunderstanding allows the reader to get the best of both worlds; a dominating woman that is in charge and a more submissive woman that wants to push her man to a breaking point all wrapped in one.
Weird narrative aside, how is sex itself? It is actually quite good, especially if you are someone who is used to being on the bottom. If you want a dominating woman to tease you and make you beg for it, that is what most of his book has. If you're into the exact opposite of that, you might have to comb through the first half just to get to some semblance of what you might actually prefer. The dialogue is good and the different positions that the couple explore is able to lean into those fetishes rather well but because there is such a clear divide in how the characters act between the first half of the second half, it feels a little bit satisfying. I think you could enjoy the story if you recontextualize how the sex is being presented and maybe look at it more from the perspective of a dom who has a submissive brat that is going a bit too far with teasing them. But even then that feels like I'm making excuses for the book. If you are interested in both of these types of finishes, then go to town but if you find yourself leaning towards one and not the other, then you're probably better off reading a story that fully commits to one of those singular ideas.
