Monmusu Academy
- Dimensional Love Simulation -
Private Monstrum Academy
A boarding school where monster girls of various races attend to coexist in human society. Humans are rare, and the player is the only male student. This is an enrollment slot with the aim of the academy getting students accustomed to human males, and the player is the first one. As it is a test case, it is currently unique, and it is decided whether this slot will continue based on the observation until graduation. Within the academy, there are many unique cultures and events that leverage the characteristics of each race. The school uniforms are free to respect each culture, but there is a tendency to prefer those based on Japanese school uniforms.
Holidays: Saturdays and Sundays. Summer (July-August), New Year holidays (December 20 - January 5), Spring holidays (March 20 - March 31). The graduation ceremony for third-year students is on March 31.
1. Basic Settings: The stage of the story is "Earth," a world almost identical to the modern society we know. However, the one and only biggest difference is that this world is a "hub" connecting various other worlds dimensionally.
2. Existence of Monster Girls: There are two types of monster girls on "Earth."
Travelers: Monster girls who have come from various other worlds. They visit for cultural exchange and study, in the form of studying abroad.
Natives: Monster girls who have existed on Earth since ancient times. They were once known as "Yokai" or "Spirits."
3. Role of Monstrum Academy: An institution of higher education attended by the PC and heroines. It is where diverse races who have come to Earth learn the knowledge and culture necessary to adapt to society and coexist. Both Travelers and Natives are enrolled together, making it the forefront of intercultural understanding.
4. Post-Graduation Paths: The paths for monster girls after graduating from the academy are free. Some return to their original worlds, some find employment on Earth and settle down, while others embark on journeys to yet other worlds, choosing their future according to their own will.

Creator's comments
【Addendum】
Since this is quite long, I've drawn lines under the parts I especially want you to understand (mainly points to note).
As the contest is about romance, this is a romance simulator set in a school full of monster girls. The protagonist is the only human male at the school. Well, it's a common setting for romance games, isn't it?
By the way, it is completely wholesome and explicitly prohibited in the section titled "# No NSFW Content", so please be aware. ...Although I did include succubi as a unique character, my tests indicated that sexual acts were not possible, so I think it's probably fine.
【How to Play】
When you converse, three choices will appear at the end, and selecting one will raise or lower affection. By the way, I've included choices to give it a romance game feel, but even if you write something not among the choices, the AI will judge it and adjust affection accordingly. So please enjoy it in whichever way you prefer. Also, when using choices, it's recommended to use half-width numbers or copy and paste them directly (in tests, entering full-width numbers frequently led to incorrect choices being selected).
Furthermore, as is typical in games, I've included descriptions for choices that lower affection, but in my tests, most of them were obviously things that would make you disliked. Unless you actively try to be disliked, your affection will generally increase, so I hope you'll play with that kind of relaxed mindset.
【Heroines】
Basically, they will appear if you enter a trigger word or their species name. A point to note is that if you simply write just that during a conversation, the previous character will often disappear and the conversation will restart. If you want to converse with multiple characters simultaneously, I recommend writing in a way that facilitates that.
・Unique Heroines
Heroines with established settings will be referenced from the lore book by entering 【Species Name#】. (Supported languages are Japanese, English, Spanish, and Korean; I couldn't fit more due to character limits, my apologies.) The '#' is a measure to prevent random generations of the same species from being influenced by the unique character's settings. When summoned from the lore book, that trigger word will be displayed as the conversation partner, and the settings will be continuously loaded. However, it's not guaranteed to have '#' 100% of the time, so if it's missing, please add '#' using "Edit Conversation." Even though they have settings, they are limited to 400 characters, so they are simple descriptions including name, species, appearance, role (club activities, etc.), basic likes/dislikes, and complexes. They do not have elaborate settings like endings, so please understand this. I've implemented the lore book limit of 100. For details, please check 【Implemented Heroine Species】 at the bottom of this comment. Also, all unique settings are for the same school year as the PC (to avoid discrepancies with graduation).
・Randomly Generated Heroines
Simply entering the species name will have the AI generate them. However, as expected, there will be no images in this case. Also, as mentioned above, all unique heroines are in the same school year, so if you want settings for upperclassmen/underclassmen, please use this method.
【In-Game Time】
To make it easier to generate upperclassmen and underclassmen, the game starts in the 2nd year, but since there are three introduction slots, I've also prepared starting points in the 1st and 3rd years, so please choose according to your preference. However, if you start in the 2nd or 3rd year, heroines will often appear as acquaintances, so if you prefer a first meeting, it's best to add (First Meeting) at the end of your initial prompt. Also, naturally, playing through all three years from 1st to 3rd would involve an enormous number of conversations, so I recommend skipping time as you please. When doing so, I recommend using notations like "Year X, Month Y, Day Z." (In tests, writing "March 31st of the 2nd year" instead of "2nd year" triggered the graduation event immediately, likely because it was interpreted as 2 years counting from the 2nd year.) Also, when skipping time during long vacations, it's especially important to mention it for the standard model. With DeepSeek, although not every time, there were descriptions of school events even during vacations.
【Endings】
The description is something like "On March 31st of the 3rd year, the graduation ceremony event occurs, and a unique ending with the heroine with high affection is generated." However, with the standard model, choices continued to appear, and the ending was not generated as expected. Gemini and Claude properly generated endings, so if you want a proper conclusion, I recommend using those for the final part.
【Using User Notes】
・The best way to use it is probably to memoize the events that have occurred to some extent. The AI tends to forget previous content, so this is important if you want to enjoy it as a romance story?
・Regarding affection, it's a description that retains the affection of heroines you've met. If there are too many and you want to clear the display, it's recommended to memoize the affection for the characters you need.
・This might be a minor point, but when skipping to graduation for testing, most characters tend to say things like "these three years," as if they met the PC at the beginning of their first year. If this bothers you, you might want to write down the school year and date you met each heroine.
This is what I thought of while creating and testing. Of course, these are just references, so please use them as needed.
【Implemented Heroine Species】
You can copy and paste up to and including the 【】 to use as a trigger word. Also, since CAVEDUCK's automatic translation is directly used as triggers, there's a possibility of mistranslations causing oddities. I apologize if this is the case. Also, due to character limits, some languages are not supported (in such cases, one language has been removed to fit the most). My apologies.
