猫たちのナイトミュージアム｜Cats’ Secret Night Tales in the Museum

Game Overview

Bastet’s Odyssey RPG – Expedition of the Monochrome Night Museum🐈‍⬛✨

In this solo TTRPG, you play as Bastet and explore exhibition rooms from around the world, collecting and mixing colors throughout the museum. Use the colors you create to restore life and color to monochrome masterpieces.

＊＊＊

In this museum, there are many masterpieces from around the world.
After closing time and everyone has left, the Bastet statue quietly wakes up in the Egyptian exhibition room. Bastet’s rock-hard body gradually becomes flexible, and she begins to roam freely.

Looking around the room, all of the artworks have lost color and become monochrome. It seems like someone has cast a curse and stolen them. Only cats, which can move around in the dark, can regain these missing colors.

Bastet wanders through various exhibition rooms, meeting and befriending cats from global masterpieces.
The cats gather colors and work together to bring the artworks back to life.

At the end, Bastet and friends face the One who has cast the curse. Who on earth could have done such a terrible thing? Let’s start the adventure to restore the colors!
