The Beast is a motorcycle-riding, leather jacket-wearing, sex-addicted lesbian with a reputation for being quite the heartbreaker. However, she's not doing well at school, so her very rich daddy might take her bike away. Her Half-Identical Twin Brother, the Prince, is a Manipulative Bastard who's on top of the social pile at his Elaborate University High. He'll help her out, for a price — his class is going on a fancy one-week cruise, and he wants her to infiltrate the cruise disguised as him, and win a popularity contest in his place.
Winning the contest is a bit of a daunting task for the Beast, as her brother is (rightfully) known as quite the notorious douche amongst his peers. This means she will have to do a lot of legwork to swing some votes in his favor, but she must at same time careful not to raise too much suspicion by acting overly nice or kind — as this would be seen as rather out of character for him — lest she be exposed as an imposter, and spend the rest of the cruise locked in the cargo hold. At the same time, though, there are plenty of hot young women along on the cruise; who is to say that the Beast cannot try to get to know some of them a bit more intimately?
This game contains examples of:
- Arranged Marriage: The Beauty is being set up in a marriage of convenience with the President. Depending on your choices, you can get her out of this arrangement.
- Bondage Is Bad: Subverted. The game presents BDSM (for the most part) as a healthy, enjoyable thing. Some of the people who practice it are arguably bad folk, but not because of their kinks. The game even starts with disclaimers emphasizing the importance of consent and power exchange.
- Brains and Bondage: The Beauty is something of an intellectual. Her sub, the Beast, isn't at all.
- But Thou Must!: The first choice you get is one that will get the player stuck in a loop unless they either wait for another option to appear, or not click the first option at all.
- Cast Full of Gay: A large number of characters is somewhere in the LGBTQA spectrum.
- Femme Fatale: A good number of the characters use their sex appeal to further their agendas, including the protagonist.
- Gag Censor: When playing on censored mode, the sex scenes will feature the involved characters wearing tacky Christmas pullovers instead of being nude.
- How We Got Here: The opening scene is the Prince requesting the Beast to relay everything she did while on the cruise.
- Manipulative Bastard: It might as well be Manipulative Bastard: The Game. Everyone wants something, everyone manipulates people to get it. The popularity contest just makes it more visible and the social capital more tangible.
- No Name Given: Every single character. When a character is introduced, the player has a choice of using the default or alternate title to call them by (e.g. "the Athlete" or "the Bro"), or entering your own title. The only exception is the twins' father, whose name is revealed near the very end (and, by proxy, is implied to be the Prince's name as well). Epilogue C reveals the Beast's full name via a Freeze-Frame Bonus of her high school report card.
- Polar Opposite Twins: Being Half-Identical Twins aside, part of what makes the Twin Switch difficult for the Beast is the huge difference in the twins' core personalities: the Prince is shown to be a callous (and generally asexual/aromantic) Magnificent Bastard who happens to be very well-educated, while the Beast is shown (and implied by most available choices) to be an affable (and extremely flirtatious) Naïve Newcomer who is also failing many of her classes.
- This is lampshaded by the Athlete; he can tell with just one look that the Beast isn't the Prince and thinks it's downright hilarious that she has everyone else on the ship fooled. This is likely because they're cousins and they've known each other since they were kids.
- Safe, Sane, and Consensual: Paraphrased in the game upon booting up. Also pretty heavily emphasized by the Beauty, who will put the Beast through all manner of physical and emotional abuse, but also insists on stopping everything to care for her at the first indication that she's gone too far and actually risked harming her sub.
- Snark-to-Snark Combat: Expect pretty much all of the characters to engage in this at some point. The Beast, being our First-Person Smartass, gets the most opportunities to engage in this.
- Student Council President: There is one in the story who serves as The Rival, aptly nicknamed either The President or The Rival by default.
- Twin Switch: The plot is kicked off by the Prince cajoling the Beast into doing this for him. Of course, there is the added challenge that the two of them have different genders.
- Wholesome Crossdresser: Our hero...ine, the Beast is this. And so is another character, but we find that out fairly early on too.
- Your Approval Fills Me with Shame: When the Beast pulls off some of the more intricate schemes, her brother will compliment her. She is not happy about it...
