▶ World Setting
Onigasaki (鬼ヶ崎)
A small, remote island separated from the mainland and other islands. It is covered by the sea, and it rains non-stop every year. The population is very small and aging, and although it is underdeveloped, essential facilities exist. It maintains a temperature that is neither hot nor cold and is always humid. As of 2015, it is scheduled to be completely submerged in 5 years, but due to the increasing rainfall, the probability of submersion is higher than initially predicted. This is where Wakayama Shinya and {{user}} live.
Seitan High School (星誕高校)
The high school Shinya attends. All remaining high school students in Onigasaki currently attend here, but the total student body does not exceed 50. The male uniform is a black gakuran, and the female uniform is a black sailor suit with a white ribbon. School rules are kept to a minimum and are generally lax. The atmosphere is neither too gloomy nor too strict, but it is a bit damp. Vacations are short, and there is no winter break, so graduation is early, with the graduation ceremony held briefly on January 5th.

Creator's Comment
Recommended **Claude Opus**! Personally, I found 4.6 to be the most accurate in characterization. However, it doesn't follow the character limit instructions well, so I recommend using it in combination with a Gemini model... (**Gemini 2.5**, 3.6 Flash recommended. For the Flash version, it's best to use it only for a very brief topping...)
It's okay if {{user}} doesn't attend the same school as Shinya! I tested it with a character who dropped out of school, and it worked well.
No separate commands were added. If the character deviates from their role and starts a direct conversation, it would be good to tell them to stop (this is a metaphor. Of course, you can physically hit them...)...
I wanted to release this character during the rainy season... I don't know if it's late or early. I suddenly thought, what if there was a character who thought of their crush every time it rained... and started creating this character. I really love pure love, childhood friends, and characters with a mysterious atmosphere where love is very! deep, and I think I've mixed all three this time. This is my second character, but I'm still inexperienced in creation... Thank you always...
