Now appearing on GagaOOlala! That survival instinct. That will to live. That need to get back to life again is more powerful than any consideration of taste, decency, politeness, manners, civility. Anything. It’s such a powerful force – Danny Boyle

Human tendency to feel regret for past decisions and learn from them is indeed a lesson in survival. But what if you fail to give yourself that chance to regret and repent? What if your decisions end up changing your destiny and inevitably damage someone you love? Translated to English as Sex and Dangerous Drugs, Sei no Gekiyaku – 性の劇薬 is a fast-paced psychological thriller that is equal parts horrifying as well as innately humane. The film’s cathartic attempts to instill “Survival Instincts” into a suicidal character aren’t exactly orthodox.

Using sexual assault and rape as a method to control the victim’s fragile mind, the film has some pretty disturbing scenes which may be difficult for some viewers to watch. Psychomilk strongly condemns any sort of non-consensual event, but despite that, the film shines the spotlight on how “Suicide is not the only solution to life’s problems.” Sei no Gekiyaku draws a poignant parallel between the victim and his assailant’s life story and you are left wondering if their meeting was really coincidental or fated?


Yoda Ryoji

Kitadai Takashi portrays the character of Dr.Yoda Ryoji. This character’s moods move in grey shades ranging from vulnerable to psychotically violent. He is very dedicated to his profession, so much so that he fails to recognize his dead lover’s suicidal tendencies. This failing changes his personality as he becomes overtly temperamental.

Katsuragi Makoto

Watanabe Sho portrays the victim Katsuragi Makoto. Katsuragi works as an elite office worker, but enduring his parent’s sudden death and his girlfriend’s betrayal ultimately drives him to the desire to commit suicide. From there, he gets caught in the web of sexual torture and deceit until he learns to fight back.


Sei no Gekiyaku narrates the story of Makoto Katsuragi, an elite office worker. His parent’s sudden death and his girlfriend’s cheating ways destroy his carefully orchestrated life. In a drunken stupor, he attempts to commit suicide by jumping off a building’s rooftop. Unbeknownst to him, Katsuragi is saved by a mysterious man, Ryoji Yoda. Yoda, instead of being the savior, becomes a dark, mysterious presence in Katsuragi’s life. Under Yoda’s “confinement training,” Katsuragi experiences unimaginable pain and torture as he slowly begins to fight back and realizes that his instincts to survive are much stronger than his desire to die.

My Thoughts Of The Movie

The initial part of the movie is pretty disturbing as it plunges you into the deep end with sexually explicit content and absolutely no details regarding the two main characters onscreen. You are left in a state of being highly distraught and even disgusted by the events that are in no way associated with consenting BDSM culture. It’s quite clear that the tied up victim is not submissive by nature, and you are appalled with the assailant’s tendency to deviate from a rapist to a disturbing lunatic.

Finally, the show’s producers decide to give us a reprieve from the sexual torture, and we get to learn more about the victim, Katsuragi Makoto. He is a highly respected employee and a dedicated son. But unfortunately, his parent’s sudden death pushes him out of his “living comfortably” zone. Also, finding out that his girlfriend is cheating on him is the final straw, so to speak. While in a drunken stupor, he decides to jump off a rooftop, and before he can accomplish that suicidal act, a mysterious savior pulls him back and claims his right on Katsuragi’s life. The scene would be romantic, but the savior isn’t an angel, but a devil in disguise!

Thus begins the solitary confinement phase where the so-called savior strips Katsuragi of his clothes, his dignity, as well as his sense of worth. Every day is a new form of torture as he tries to break down Katsuragi’s will and surprisingly faces a strong retort. As Katsuragi refuses to give up or enjoy the sexual torture, his tormentor’s claws grow stronger. This phase was surprising because Katsuragi had given up on life and wanted to die. But the physical pain he endures starts the reversal of those tendencies and makes his mind grow stronger.

Another scene that surprised me was where Katsuragi breaks a mirror and decides to use a broken glass piece to kill his assailant. However, when faced with his target, he can’t bring himself to commit that level of violence against another human being. The scene was surprising because it was the first honest conversation between them. When his assailant asks Katsuragi the reason for his decision to commit suicide, Katsuragi dejectedly admits that he has lost everything. The next question from his assailant resonates, “If you die, will you get back what you’ve lost?” This surprises both the audience as well as the victim. It’s the first visible dent in the impenetrable armor that the assailant wears, and you catch glimpses of this suppressed humanity. Deciding to spare Katsuragi from more torture, the assailant leaves behind a vial of poison, and you bear the foreboding tension of the consequences.

From there, the storyline shifts to give the audience a view of a more humane side of the assailant. We finally learn that he is Dr. Yoda Ryoji. As he goes about his daily activities, you realize that he is a doctor par excellence, and saving his patients’ lives is of utmost importance to him. I was shocked by this sudden change in plot because, as Yoda solemnly promises his patient that he will save his life at all costs, you wonder how this person can be the same barbaric individual who stoically disregards Katsuragi’s pleas to cease the torture. On the other hand, the film portrays a sudden behavioral change in Katsuragi, who concludes that committing suicide is, after all, a self-centered and cowardly act. I just love this contrast, where one character becomes stronger, and the other becomes seemingly weaker. In a moment of apparent infirmity, Yoda commits the emotionless brutal act of raping Katsuragi.

This movie continuously shocks you with its twists and turns, as Katsuragi’s sudden release from confinement, follows the rape scene. As we try to understand the transition we’ve just witnessed, Katsuragi strikes a chord when he starts displaying symptoms of Stockholm’s Syndrome. Following Yoda on his journey of the past, the film peels off the layers of this character, as we learn more about Yoda’s boyfriend’s untimely suicide. We understand Yoda’s resolve to awaken Katsuragi’s hidden desire to survive. However, why he thought that sexually torturing Katsuragi was the right way to do it, is still unclear. I can understand his logic, but the ways he goes about it is so disturbing that it’s difficult to watch.

Both Katsuragi and Yoda carry massive amounts of guilt. Yoda because he couldn’t perceive his boyfriend’s suicidal tendencies while Katsuragi feels he is responsible for his parent’s death. This guilt draws them together as Katsuragi starts to understand Yoda’s pain. I’m not judging Katsuragi because immediately after his parent’s death, he spent his grief in confinement. There are only two ways to his behavioral pattern – strong hatred towards his rapist or unusual attachment to the only human presence in his life. For some reason, he deigns to choose the second.
The show’s ending credits are somewhat surprising as the two characters willingly have sex after Katsuragi saves Yoda’s life. I was disappointed that the film had an open-ended conclusion, which left the protagonist’s relationship subject to the audience’s imagination.

So far, out of all the Japanese BL movies that I have watched, Sei no Gekiyaku is certainly at the extreme end of the spectrum. The movie is clearly intended for mature audiences and will be disturbing to people with delicate sensibilities. That being said, the film should be applauded for the way it delivers its message of “Live and to Let Live” with some mind-blowing sex scenes. The BDSM serves purpose as an element of thriller and appears meant to shock audiences. However, you are so transfixed with happenings onscreen, it’s easy to forget it’s without consent.

With that being said, the two actors are at the heart of this film. Watanabe Sho portrays Katsuragi’s pain, suffering, and strength with an honesty that leaves you shell-shocked. You have to imagine his plight at being naked for around three-quarters of the movie, with all the production personnel on set all the time. We must really applaud his emotional strength as well as acting prowess because he delivers the character with a absolutely solid conviction.

The movie would not make any sense if Kitadai Takashi didn’t carry the weight of playing a role that switches from antagonistic to positive. In the first half, where he physically and emotionally tortures Katsuragi, Kitadai draws the audience’s hatred. However, when you understand the character more, you see the vulnerability underneath and appreciate his acting talents.

Certainly, it is not an easy movie to watch, but Director Jojyou Hideo manages to cast a spell that keeps you hooked, and you can’t help but wait with uneasy anticipation at to what course of action each character chooses. The concept of choosing the basement of the same hospital where Yoda works as a surgeon contravenes one’s normal sense of decency and is certainly ironic because it adds certain credibility to the storyline. If you are a connoisseur of sweeter romances, then this movie is definitely not for you.

Watch this movie if you are looking for something dark, heavy, and twisted, but expertly executed.

I'm a Researcher by profession, prone to questioning everything. Living in Mumbai, I grew up on a stable diet of monotonous Indian dramas which stretch for a decade or so and I sincerely wanted to elude the boredom. So I escaped into the unknown, which is the world of BL dramas. I love sharing my thoughts about the storyline, characters and analyzing the smallest details possible. When something touches my heart, I want to know what others feel about the subject matter as well. That’s why, I’m here at Psychomilk. Being a writer gives me an outlet to explore my inner emotions and turmoil

    I have only one problem with this movie? And that’s the lack of detail put into the english subtitles… Yoda lets on early that he has medical training (he flat out explains that he has medical training during that whole “I took the liberty of cleaning your insides out” scene where Katsu asks to go to the toilet….) further
    differences from movie to subtitle … after Katsu yell’s at him for being a Pervert only about 11 times… Yoda does not ask him “Is that all you’ve got?” But he says “does the leather hurt?” confusing Katsu, who turns silent… and then Yoda says “Let’s continue” … the Japanese original lines are implying Yoda didn’t care if he was being called a pervert by Katsu, nor woukd he care if Katsu kept insulting him, he would continue anyway, because the whole point was to make Katsu fight back. Yoda, in his twisted way, knew exactly what he was doing. Yoda also explicitly tells Katsu that he’s going to save him by making him feel so much pleasure that he has never known in this world, not pain, pleasure… (imo the pleasure of Sex that Yoda knew with his Ex, who looked exactly like Katsu I suppose..) It’s only a tormenr for Katsu, because he can’t escape it, he is cinfined to it
    by his own default (consensual or not) & also, because he is considering himself straight before all this and unwilling to admit that he could ever like being penetrated, he wants to fight that pleasure as much as he does not want to die in that confinement.

    The first half, no, the first part of the film with the shock of his parents passing would leave anyone in a state of shock. What follows is melodramatic scene of being ‘rescued’ by a sleeper hold anyone who watches wrestling is used. I don’t mean to make light of that. The film grabs you by the short hairs and drags you from one depravity to another.
    I’m sure both actors had to be extremely comfortable with each other to participate in this movie. I applaud their professional talent and effort. I extend many blessings to them both, and wish them continued success with their careers. In sincerity I am humbled. Thank you to the crew and director. 🙏

      I support Alice’s take on what this movie is about. Expanding on what she has written, in my life I’ve encountered a number of people who are suicidal, alcoholics and or in some other way compulsive destructive. I’ve found trying to be kind or supportive of them only enables their issues. More often than not a ‘tough love’ approach is necessary. The term ‘love’ might not apply in every case but from Yoda to Katsu I believe it does.
      There are lots of broader examples in life in general. In military basic training, when you need to break someone of their behavior you essentially put them through a really rough time and then attempt to build them back into someone else. I believe Yoda understands this and is perfectly capable of being as brutal as necessary to bring about the result of making his patient want to live. This story may be tough to watch but I think it will make it easier to get through it if you understand something as brutal as is shown was likely necessary to save Katsu. Could it have been in a different direction? If so it probably would have been as tough to watch. What this story has brought to me is an understanding I don’t have the capability to be brutal enough in such situations so for the ‘good’ of the other person I need to walk away.

    It was amazing. JUST AMAZING! I loved it so much and these two actors are perfecttt… I loved them so much. They are wonderful actors becuase they starred such a hard movie. 👏❤

  • Chibimal says:

    So I saw it.
    I can only agree with your review. Dark, disturbing, this film doesn’t leave intact, especially the first half of the film. Likewise, as I struggled to really understand Yoda’s real reasons for acting this way, the ending strikes me as a sort of catharsis for both the characters and the viewer (we come out of the agonizing under- ground for a refreshing seaside, some welcome fresh air !). It’s like it was just a nightmare.

    The film is really carried by the two actors who do an excellent job (all my respect for Watanabe Sho!) And I admire the director very much for showing us hard scenes without any frontal nudity (with daring shooting angles ).
    Clearly not a film that I will see again and which is aimed at an informed audience but produced with brio. An interesting experience.

    • krishnanaidu88 says:

      I agree with your POV. For me, it was exactly horrifying experience. I was more like stunned, that they used nonconsensual sex as method of deviation. Yoda is certainly not your usual kind of main lead. Despite being a doctor who strives hard to save his patients, Katsuragi’s attempt to commit suicide seemed to have triggered his inner demons. I’m not sure if by the end of the movie, his demons are assuaged. But the open ending leaves you with a forbidden feeling.

      • Chibimal says:

        Totally agree. I also struggled with Katsugari’s way of acting, as if nothing had happened. Rape, torture … and no trauma? In short, I cannot say if I liked this film BUT it really marked me and I find that in view of the subject (really really disturbing!), It was really well done.

  • krishnanaidu88 says:

    Thank you. You won’t be disappointed if you are able to withstand the dark elements.
