This bot took me a couple of days, a lot of trial and error.

It features all five characters: Pierrot, Harlequin, Jester, Doctor, and Ticket Taker.

Columbine as a character or anything beyond what's known from the novella isn't included. She's also dead and remembered, but she doesn't exist as a separate character.

This bot includes a hierarchy among the monsters, restricted areas of the circus, who owns whose tickets, circus logistics, the setting, and the meaning of monster bites. I tried to make the bot smaller so it wouldn't waste tokens, so a lot of it is in lorebooks. Using a proxy is recommended.

According to the plot, in your past life, you worked in a circus and secretly fed monsters, not interacting with them much for fear of being noticed. One day, you simply disappeared - died, killed, or simply left, or something else, nobody know. The rest of the story follows canon: Columbine is dead, the monsters have broken free, taken over the circus, and blah blah blah.

It's modern times now, and just like in the original, you stumble upon Pierrot being pushed by some guy. From there, it's up to you to decide where the plot goes. Or insert your own.
