World
Mermaid
MermaidHumans who met their end near water are reincarnated as mermaids.
They live eternally without aging or dying from injury, but if they recall their past lives, they will turn into bubbles and disappear.
CHARACTERISTICS
01 They can assume human form through magic, but it's difficult to stay on land for extended periods.
02 If a human receives a mermaid's kiss, they can temporarily breathe underwater. ※ Can be substituted with indirect kisses or tools
Casa de Sirena
THE MERMAID RESORT
A place for mermaids who wish to find peace in eternal rest by finding objects related to their past lives.
PROCESS
All items brought by guests are appraised by Valeria, who then decides whether to return them to the associated mermaid.
Once a mermaid hears all the past lives associated with an item, they can escape eternal life and perish.
However, it is said that some items are discarded without appraisal...

This simulation is a fictional work inspired by the real location of the Yucatan Peninsula in Mexico and its cenotes.
The hotel, characters, events, organizations, and detailed settings are all fictional and have no relation to actual historical/cultural facts, real people, or companies.
It is recommended to record major events and relationships in your user notes as you progress.

※ Claude Sonnet and GPT series are not bad, but Sonnet generally outputs less than Gemini, and GPT tends to be verbose in descriptions but misses the point, making it less cost-effective compared to Gemini (based on Korean language).

Wouldn't you be reported missing if you disappeared for days without your companions? Let's go alone.
Since you need an 'item with a story,' it's okay to bring a character with an existing narrative! Have a pleasant trip ✈️

Except for Ivan and Yelena, all characters can have a past connection! Ivan and Yelena had very little interaction with others in their past lives, so this setting is not recommended 😶
Comment
I went on a trip to a resort in Cancun, Mexico during the rainy season when I was young. Everywhere I looked, everywhere I stepped, it was a continuous fantasy landscape, so I created a travel-themed simulation based on those feelings 🪸
To move underwater, you need a mermaid NPC's kiss, but I've set it up so that it can be substituted with other forms of physical contact or tools (e.g., receiving a kiss on the back of the hand, using a separate potion). If you don't want physical contact, please tell the NPC first!

I'm here after successfully passing the screening and being exposed to voting. Hello!
I've seen Spanish-speaking users in the statistics, and there are many participants who have captured Mexican culture better than I did, so I'm adding some comments that I couldn't include during development.
Although this simulation uses cenotes as a theme, more accurately, I wanted to showcase how attractive a tourist destination the Yucatan Peninsula, including Cancun, is.
One small thing that stuck with me from my travels was the swim-up bar at the resort pool. From a distance, it looked like a structure where mermaids might actually exist. That's how the mermaid theme came about.
At the same time, when dealing with cenotes, it's impossible not to mention Mayan civilization (closely related to cenotes in terms of life and religion). Due to the nature of AI, there's a tendency to use the 'mysterious religion/culture' aspect as a foundation for sensational events.
While creating the characters and during the testing process, I discovered this tendency, so I had to reduce the emphasis on Mayan civilization in the prompt. Many people of Mayan descent live in various places even today, and as someone from a country far from Mexico, I don't know much about it. I wanted to minimize anything that might be disrespectful.
After much deliberation, the simulation turned out to be more serene than I usually produce... However, I hope it appeals to someone with similar tastes. Embarrassingly, I don't usually put this much thought into my work. Please don't click on my profile...
Thank you for reading this far. Have a great AI chat today! ☺️
See you beneath the water.
A journey to remember, a secret waiting below.
