Theme glossary

The following is a list of approved themes.

Terms that lack definitions are regarded as self-explanatory.

Narrative

 * Minimal Narrative - Only a few sentences here and there are used to narrate the work's story.
 * No Narrative - There is no verbal explanation of the premise of the work's story.
 * Rich Narrative - The work's story is thoughtfully constructed, with coherently behaving characters and an engaging plot dynamic. Expressive writing is only one component of narrative, so rich narratives don't all necessarily resemble high literature. As a rule of thumb, this theme could apply to any memorable story. Do not apply this theme to every work that has more than just a "minimal" narrative; most works' narratives are somewhere between minimal and rich.

Location

 * Contemporary Fantasy - Modern day Earth, but with fantastic elements.
 * Contemporary Sci-Fi - Modern day Earth, but with science fiction elements.
 * Future Fantasy - Takes place in the near or distant future of Earth, with the presence of fantasy elements.
 * Future Sci-Fi - Takes place in the near or distant future of Earth, with the presence of science fiction elements.
 * Historical Japan - Pre-industrialized Japan, depicted in a way that isn't necessarily historically accurate. May include the presence of fantasy elements like youkai (monsters) or supernatural ninjutsu.
 * Medieval Fantasy World - A world that isn't Earth, with fantasy elements like magic or monsters, in which states are typically feudal monarchies, the industrial revolution apparently hasn't happened, and inventions like cars, telephones, and computers don't exist or are extremely rare. Society resembles a fictionalized version of the Middle Ages or the European Age.
 * Modern Day - Modern day Earth.
 * Modernized Fantasy World - A world that isn't Earth, with fantasy elements like magic or monsters, in which society's state resembles the 20th or 21st century with the presence of apparent industrialization and inventions like cars, telephones, or computers.

Plot elements

 * Combat Sports
 * Confinement - Imprisonment of characters is a central theme of the story.
 * Gekokujou - Refers to a plot where a female character whose position previously required her to follows the orders of another character (an employee to a boss, a maid to a master, a slave to an owner) instead plots to overturn the status quo and dominate that other character. This is a Japanese term that can be translated as "the lower rules the higher", and which is in use as a content tag on the Japanese erotic doujin store DLsite.
 * Hero and Demon Lord
 * Slavery - The plot heavily features people who engage in the slave trade, which may or may not actually be legal within the fictional setting. Should not be confused with lifestyle BDSM.

Protagonist
There are no single protagonist or male protagonist themes because those are considered the default assumptions.


 * Both Female and Male Protagonists
 * Multiple Protagonists
 * Protagonist Choice

Other

 * Free
 * In Development - Development of the work is considered to be ongoing, with future updates forthcoming. Note that if the work is categorized as "complete", that means the work is far enough into development that it already contains all major content and has a proper ending, so future updates would probably just add optional side content or other improvements.
 * Supporter-Only Updates - For in-development works, the case where the developer releases at least some of their work's updates only through private posts for paying subscribers on crowdfunding platforms like Patreon or Ci-en.

General

 * All [Fetish] - A specific fetish from the fetish glossary is present in every single femdom scene.
 * Consensual
 * Cohabitation
 * No Penetration by Male - No male characters sexually penetrate the anus, vagina. or mouth of any female characters.
 * Only A Single Penetration by Male - There is only a single sex scene in which a male character sexually penetrates the anus, vagina, or mouth of a female character.

Gameplay

 * Battle Fuck - Sex-based battles. To elaborate, the player character and enemy female characters engage in a battle system which doesn't involve physical violence, where they attempt to cause each other to orgasm by using sexual attacks that raise the other's arousal, with orgasms typically causing a reduction in sexual stamina, and reaching zero stamina being equated with loss of the battle. This is a Japanese term which is often abbreviated as "BF".
 * Game Over Rape - After the player character loses a battle against a female enemy, she sexually dominates them, which they are unable to resist due to having been incapacitated or weakened from their loss. After the sex scenes are over, the player finally receives a "Game Over" and must load an earlier save.
 * Game Over Rape (Bosses Only) - See the "Game Over Rape" theme. This is game over rape that only occurs when losing battles against "boss" enemies, which are specific female enemy characters, and does not occur for generic female enemies.
 * In-Battle Arousal Gauge - Refers to a battle system where the player character has a sexual arousal gauge in addition to their HP gauge while in combat with enemy female characters, which is raised by their sexual attacks, and having a high arousal gauge makes the player character more vulnerable to the enemy's attacks or induces the player's loss. Don't apply this theme to BF games, where it's already assumed that arousal can lead to loss in battle.
 * Loss Rape (Continue Playing After) - See the "Game Over Rape" theme. Game over rape in which instead of receiving a "Game Over" after the sex scenes, the player is able to continue the game normally. Often, this involves being brought to the nearest inn or having time reversed.
 * Victory Rape - In the case that the player character is female, after winning a battle against an enemy, she sexually dominates them, which they are unable to resist due to having been incapacitated or weakened from their loss.

 * Submissive Female Protagonist
 * Submissive Futanari Protagonist
