Ryoko’s Guide to the Yokai Realms

Conceived as a love letter to Japanese folklore and mythology, the book draws inspiration from iconic works such as Avatar: The Last Airbender, Princess Mononoke, Sekiro: Shadows Die Twice, and Monster Hunter.

Designed as a complete "Eastern Fantasy" experience, the book overhauls high-stakes combat through several brand-new systems:

• The SuperGargantuan Kaiju System, a full framework for battling city-sized monsters by targeting vulnerabilities, scaling creatures, and managing their rampage phases.
• Combo Attacks, a cooperative combat system letting players chain their turns together for cinematic, high-damage team-up moves.
• Ninja Prostheses, inspired by Sekiro, customizable with grapples, hidden blades, and other gadgets.
• Dynamic Crafting, allowing players to harvest parts from defeated Yokai and Kaiju to forge unique magic items.

On the character side, the book introduces the brand-new Bender class with its four elemental disciplines, 16 new races drawn from Japanese folklore (Kitsune, Tengu, Enkoh, Tatsumi, and more), as well as 14 new subclasses, dozens of spells, feats, and magic items.

Finally, a rich bestiary of over 60 creatures — traditional Yokai and towering Kaiju alike — rounds out the Game Master's toolbox.

An essential supplement for tables looking to explore an epic, spectacular adventure deeply rooted in Japanese culture.
