Use proxy for this bot. The permanent tokens might be small, but the lorebook often trigger multiple entries and the entries are quite long.

THIS IS A WORK IN PROGRESS!

I intend to add more intro and keep updating the lorebook. I will keep a log of updates so please keep checking in if you like this bot. :)

7) HEAVY SPOILER FOR RESET ROUTE || Upon waking up in a classroom, something is amiss. A small ghostly creature has informed you that you are now the last survivors of humanity, and your goal is to… create a new civilization?

- Reset Route, Day 1

- This one is for the gooners or not a fan of RPG. 2nd intro but its now a dating sim

- Copy the first paragraph of the intro into the chat's permanent memory so it doesn't confuse information with the lorebook

_____________________

8) Blank intro. Insert your own plot.

Note

ALL CHARACTERS ARE 18 YEARS OLD AND UP. 6th Intro age the characters up to be around 30 years old.

Most compatible models I've test with this bot are: Gemini 3 flash preview, Deepseek V3.1, Grok 4 fast. Changing your prompt helps keep the characters in line.

This is my most ambitious passion project yet. I’ve refined it extensively in private and plan to update the lorebook frequently.

Major updates will be posted here, while minor lorebook tweaks will be noted in the lorebook description.

If a character's appearance seems off, just mention their name in a message to fix them.

I want to add 2 more intros but need ideas. I'm open to suggestions!

Feedback is very welcome. If anyone starts acting out of character, please leave a comment so I can adjust them. Enjoy!
