Superstar Variable Venus

Superstar Variable Venus (スーパースターバリアブルビーナス) is a 2004 platforming adventure spinoff video game developed and published by Gamesoft. Set in a different locale from the main Superstar series, it focuses on a group of females who are tasked with protecting the Scarlet Skyland from the invading Plasmarians. The game play introduced new elements to the Superstar franchise including the ability to lock on enemies and run up walls. It was released exclusively for the Game Boy Advance.

Plot
The game is set in the Scarlet Skyland, a floating world that is a complete knockoff of the oh-so-superior Land of the Sky. Scarlet Skyland is also inhabited with humans and monsters co-existing in sexual harmony. Penny Dots and her monster friend Pufftop Cakester were researchers of sexual activity. Their research tends to be a failure because nobody would give them the D. However, their lives changed when they encounter an actual alien fucking some monster fags somewhere in the premises. After nearly being raped by this alien, they meet with L’arc Coilina, a human/Mechaking hybrid who works as a hentai expert, who grants them some...explicit weapons for giving these aliens the whatfor, known as Plasmarians. Also joining the team is Gabby Leecha, the town slut of the Scarlet Skyland who knows the floating city’s men, be it human, monster, or even Mechaking, and Kenn Scarecrow, the NTR mentor-figure of the heroines. Now with the ability to become sluts and create sex toys from their enemies' sperm, the heroines enter the fray to save the Scarlet Skyland from the raping aliens.

Characters

 * Penny Dots: One of the four heroines of the game. Living in a rural part of the Scarlet Skyland, Penny is a ditzy and studious bitch who works as a sex researcher alongside Pufftop. When the Plasmarians arrived and almost impregnated her and Pufftop, she met with L’arc and became a slut to castrate the aliens. Penny’s primary weapon is the Pierce Raygun.
 * Pufftop Cakester: A cake monster who has been Penny’s partner in sexual research (wink wink, nudge nudge). She often gets enraged when they are not given the D. But when she noticed the Plasmarians in the city of Scarlet Skyland tossing salad, she and Penny meet L’arc, who gave her some sex gear to drive these Plasmarians away from this Christian server. Pufftop’s primary weapon is the Fetus Hammer.
 * L’arc Coilina: A human-Mechaking hybrid who once faced a lethal illness (not AIDS, that's for sure /s). She was converted into a Mechaking cyborg before she had any chance of doing it. As the daughter of a hentai artist, she has access to the gear based on some hentai that will soon be used to stop the Plasmarians from claiming Scarlet Skyland's babes (and dudes) as their own. L’arc can switch between her human and Mechaking forms, complete with some oddly-shaped tentacles.
 * Gabby Leecha: The town slut of the Scarlet Skyland. She knows the men of the floating land after taking several D's in the past. She joined Penny, Pufftop, and L’arc after the invasion of the sex-driven Plasmarians began, which led her to become a slut to fuck them. Gabby’s primary weapon is the Ti-T Whip.
 * Kenn Scarecrow: A scarecrow monster that acts as a mentor to the heroines. Aside from that, he claims to be incompetent in sex, likely because of his cuck status.
 * Shun: The main antagonist of the game. Shun was an inmate of Beldora Prison, where he was sent to after committing inappropriate sex experiments on both humans and monsters (to both genders, no less!). To get his revenge, he built a signal that attracted the Plasmarians to the Scarlet Skyland, thus beginning their version of the Rape of Nanking, except not as brutal.
