Kingdom of Passion is an adult role-playing adventure by Siren, made with RPGM and shown through animated 2D CG. You play a young Prince adjusting to life in Valencia, a lively kingdom full of beautiful women. A strange force drains affection from residents, so you and your new ally Aphrodite work to restore it. The game mixes relationship building, castle exploration, and puzzle solving, and it serves as a prequel to Town of Passion. Core themes include fantasy, adventure, and corruption.
Beta v0.10.5, released August 10, 2026, shows development is ongoing. It runs on Windows and Android in English, uncensored. This build adds bath towel and bath robe outfits for Queen Eliza and Lydia, plus new bath house scenes for them. Side quests now grant Premium Bath Tickets tied to those characters. After finishing Lydia’s main story and opening Alexandria’s jousting tournaments, the Soapy Cup appears, a scantily clad contest where taking hits hurts more. Unlocking Goddess Slice also expands the hidden underground area west of Sophie’s Chapel, and a Bunny Girl is preparing another special game.

Queen Eliza - Bath Towel

This update includes new sidequest activities that reward special new Premium Bath Tickets; exclusively for Queen Eliza and Lydia!
After completing Lydia's main storyline, as well as unlocking the jousting tournaments from Alexandria's storyline, a new jousting tournament will be available.
The Soapy Cup features a hardly-dressed tournament against a bunch of babes. Being vulnerable means you'll take more damage from hits so be careful!
Additionally, when you've unlocked Goddess Slice from the main storyline, the hidden underground area just to the west of Sophie's Chapel has a newly expanded area.
A Bunny Girl has been working on a new special game called Treasure Hop. Hop across the stones in time to find the rare treasure!
Both of these new activities will reward you with Lydia's Premium ticket and Eliza's Premium ticket which can be redeemed in Lydia's bathhouse.
These special events also unlock outfits for both Lydia & Eliza to change in to!
== Relationship Menu ==
A new pause menu option is available! You can now view your current relationship status with all of the main progression girls. This is a convenient way to check
if you have 1, 2, or 3 hearts with each of the girls. Eventually, you'll want to make sure this screen is maxed out in order to progress through the main storyline!

OILER]
This update features a brand new sidequest storyline for Penny! The Pretty Patissier!
In order to begin the new story content, you'll need to work at least two shifts
at the bakery. Previous save files were not tracked so you'll still need to work the two shifts even if you already have in previous updates. From there, talking to her will begin the new story content!
While the Prince isn't the handiest helper in the bakery, his swift & agile form makes him the perfect candidate for fetching Penny's ingredients!
You'll need to dodge Goblins, ghosts, and other perils to help Penny with her desserts!
