Secrets per Character Introduction

You can now set a unique secret for each character introduction!
Add variety by assigning different secrets to each intro for your characters.
For characters with multiple introductions already, their existing secret has been copied to each one—feel free to edit as needed.

Where to find it: Create > Character Creation > Add Introduction Setting
We're also preparing more features linked to introductions—stay tuned!

Custom Prompt Feature Removal
The custom prompt feature will be temporarily removed for future improvements.
It will no longer be available starting June 5 (Thu, UTC).
Characters using custom prompts will automatically be switched to the default roleplaying prompt.
We're working hard to reintroduce it with significant improvements!

Thank you for your input, Kaine

I mean, I can try to add Gensokyo as a setting, but I can't promise results since I'm worried I might break the bot.
