FIRST STAGEMeteor Shower Record
At Seisai Music School's Hinamise, the same script is always performed. A traditional first story that everyone knows. "Meteor Shower Record" (流星雨レコード).
On the night a meteor shower not seen in a hundred years is predicted, a man enters an old record store. Kanata, who claims to be a wizard born from a meteor. If he cannot engrave the most beautiful sound before the meteor shower ends, he will lose his magic and memories. And the store owner, Mio—has a song she buried long ago.
Six roles: Kanata · Mio · Shun · Yomi · Fuuka · Yurie. 🎵 Listen to the Representative Number

There is an old superstition at this school.
"The lead of Hinamise sits on the 'Hoshi no Za'."

STATISTICSStats
This simulator uses a total of four stats. Each stat can be raised up to 100, and the role in the currently ongoing performance is determined by the total sum.
By default, {{user}} will be assigned to the role they desire, but if their stats are too low, they may not be selected for a lead or supporting role. The required stat values for each performance are not disclosed, but you can proceed without issue by occasionally attending classes/practices as time and the narrative progress.

🎤 Vocal
A measure of pitch, volume, breath control, and the ability to deliver large musical numbers.
⚔ Physical
The overwhelming persuasive power of the body in dance, sword fights, waltzes, and group choreography.
📖 Interpretation
The ability to handle dialogue, the depth of emotional arcs, and understanding the director's hidden intentions.
✨ Presence
Star quality that forcibly immerses the audience, the ability to capture attention.
✦ Sub-Stats
• Condition (0~100): Decreases can cause stage accidents and injuries. If the value drops below 35 two weeks before a performance, or below 25 normally, you will receive a warning and be subject to Rakusei. Overwork increases stats but drastically lowers condition.
• Reputation (0~100): The trust level from faculty, audience, and peers. As it increases, so does the attention, but attention is always a double-edged sword.

GUIDEFOR PLAYERS
🤖 Recommended AI Model
Recommended to start with Gemini 2.5 or 3.5 Flash. Models other than Opus 4.6 may cause widget output errors or be unsuitable for the simulator on the first turn. Opus 4.6 has low output volume, so it is recommended to use it for important acting & performances rather than from the beginning. If user impersonation is allowed, level 1 is recommended; if not, level 0. If you want to become a stage sensation, level 1 is strongly recommended.
✦ One-line evaluation of tested models
Gemini 2.5, 3.5 Flash (mixed with 3.1 Pro): Most stable for the beginning and produces characters well. Occasional foolishness requires a reroll.
Opus 4.6: Most stable but low output. Given the simulator's characteristic of talkative characters, it's recommended only for crucial moments rather than daily life. 4.7 is a bit more strict, and 4.8 doesn't follow output instructions.
GPT 5.4: A model where daily life and performances are 극명하게 갈리는 (sharply divided). In daily life, the dialogue is too verbose, and all of it is uninteresting. The sensory descriptions during performances are beautiful.
DeepSeek V4 Pro: Decent. If used for a long time, widget errors and sentence collapse may occur, so switching is recommended.
Sonnet series & GLM 5 & Base models: Difficult...

🕹️ Play Guide
✦ Time Skip Recommended: Once you have sufficiently built up the narrative or stats for the week, please proceed to the next schedule. Of course, if you wish, you can enjoy delving into every single day.
✦ During practice times with no scheduled events?: If you don't know what to do, use the commands !class or !practice, or input one of the following: script reading / blocking check / costume check / stage rehearsal, and the AI will proceed appropriately!
✦ User Notes: Actively recommended for use. Recommended to record the roles each character takes in each performance / relationship changes / growth. Be sure to record any nicknames given by Gingga to {{user}} in your User Notes or Persona. Actively utilize the !summary command! The AI tends to forget script dialogue, so if there's a line you like during chat and want to quote throughout the performance, write it in your User Notes. You can delete it after the performance.
✦ Official Setting Errors: While we have tried to fix errors as much as possible, errors may still occur depending on the AI model's state, even if strongly prohibited. If an error occurs once, it tends to persist, so it's recommended to fix it immediately upon discovery!
A man appears!!!! / Meteor Shower Record becomes a script written by Tsubaki / Himawari suddenly becomes a senior student and becomes an older sister who has been cooking for a very long time / Everyone thought they were freshmen meeting for the first time, but why are they acting like they know each other? / The script seems strange (This is due to the lore book not being loaded properly. Please input the performance title and reroll.)
✦ What to bring: A mindset to enjoy

⌘ Command Guide
!class [Subject Name] You can take classes in dance, singing, acting, or directing. Each can raise Physical, Vocal, Presence, or Interpretation stats, respectively. (Other stats may increase depending on the class content or the character's development.)
!practice [Character Name] You can practice with the selected character. Random stats increase depending on the practice content. Relationship changes with the character also occur, sometimes leading to growth for {{user}} or the character.
!summary Summarizes the last 30 turns of conversation. It helps with memory by utilizing User Notes and overall narrative summaries. Since the volume of two years is large, characters often forget, so using User Notes is highly recommended!
!epilogue Post-graduation epilogue. After the graduation ceremony, use this command to output an epilogue in letter format. We have prepared an ending song, so listening to it along with the epilogue is recommended. 🎵Song (Click to go to YouTube)
※ Gemini 2.5 recommended for summary and epilogue commands

✦ When you can't think of how to play
{{user}}, who entered the school after being caught by someone important or a professor without knowing anything, {{user}} who knew someone among the NPCs in the past, try becoming a professor's favorite student, I was so jealous I tore up the script, get involved in a scandal with the person of the blue rose, try to film a love and war drama off-stage, Enjoy your youth!!

✎ Developer's Comment
Influenced by: Takarazuka Revue and Music School, Glass Mask (The person of the blue rose is an homage to Glass Mask!), Iwajima Opera School (Damdo Baekgyeong), Kageki Shojo!!, Jeanne d'Arc, Revue Starlight….
I've always wanted to create a simulator called 'Let's perform until I die' because I love the stage so much, but I knew I would never make it if not for this contest and the safety simulator. So I worked hard to make it. At first, I considered making male personas possible (a remnant of the playwriting and directing department...), but honestly, looking at the list of influences, it had to be a GL simulator. This is my first simulator, so I think I was too ambitious^^;> I feel like I spent the entire period fixing errors, but from the middle onwards, I realized that no matter how hard I tried, everything would depend on the AI's state and luck, so I let go a little…. I pray that the AI will do its best for all of you who play, and I'm entering prayer mode. If there are any serious errors that prevent progress, please leave a comment!
The most important thing I focused on when creating this was 'ensemble drama'! I love stories where {{user}} is the center, but the NPCs also interact with each other and show their individuality, so I worked hard on it, and I think it turned out as I intended. During the test play, I proceeded as a country girl who didn't know what acting was. I played a supporting role, helping characters grow, rather than a lead, and it was fun! The lore book only contains the synopsis + characters + lyrics of representative numbers, so everything else is the AI's creation. Just like countless stars, none of which are the same, please enjoy your own stage under the Seisai night sky^^7
+ I always prioritize immersion, so even if it's not perfect, I tried to create the atmosphere! I made the stage numbers using Suno, but since I couldn't create duet songs, I had to edit them by hand, so I couldn't match all of them to the time. I plan to upload all the assets (especially Tsubaki!!) and all performance numbers over the weekend. And after uploading, I realized I had written too much and it was suffocating, so I will organize the content neatly tooㅠ_ㅠ7
