StoneHead Productions made One Piece: Passion on the Grand Line as a Ren'Py adult visual novel and adventure game with animated 3DCG scenes. It uses a One Piece-inspired setting while following an original story. You play Renji, Shanks' son, raised in Sunnyland, a peaceful island populated by familiar figures and hidden secrets. He wants to become a pirate and sail like his father, but first must handle relationships, challenges, and his personal legacy. The game includes multiple choices and a sandbox feel, with parody elements and harem relationships.
The current build is v0.4.0, released May 31, 2026, and development is ongoing. It is available for Windows, Linux, Mac, and Android, with English, Spanish, and French language options, and it is uncensored. The latest update adds new Hina, Midou, and Makino scenes and events, reworks Alvida, expands dialogue and interactions for several characters, introduces a naval combat system, redesigns enemy combat, adds locations and story progression, and includes upgraded visuals, fresh renders, and convenience improvements. The creator describes this as the start of planned East Blue arc content.

v0.4.0
Highlights of Version 0.4.0
New scenes and events for Hina, Midou, and Makino
Completely reworked Alvida
Expanded dialogue and interactions for several characters
New Naval Combat System
Completely redesigned enemy combat system
New locations and story progression
Various visual upgrades, new renders, and quality-of-life improvements
This update is only the beginning of what I have planned for the East Blue arc. The story will continue in future updates, and I genuinely believe some of the best content in the game is still ahead of us.
v0.3.3
Changes & Fixes
Updated backgrounds for:
Alvida’s room
Interior of Nefertari Vivi’s ship
Vivi’s room
Added ambient NPCs to improve immersion in:
Tavern
Plaza
Port
Beach
When a pirate visits the island, their crew will now also appear, causing chaos around the area and making the world feel more alive and dynamic.
Fixed grammar issues
where female characters were incorrectly referred to using male pronouns
Fixed the Midou bath scene, where some images were displayed incorrectly or cropped
Replaced invisible navigation zones with discreet arrow indicators, improving the sandbox experience — especially for Android users who couldn’t see hover-based navigation
v0.3.2
Major Fixes & Improvements
First of all, I’ve fixed the beginning of the game. Seriously… I didn’t realize how broken it was, with several major visual bugs and inconsistencies. I sincerely apologize for that.
Another important improvement is that we’ve also updated the walkthrough system, making it much easier and more intuitive to follow, so progressing through the story should now feel smoother and more user-friendly.
Hina Rework
Hina has been fully reworked, including her 3D model and all her animations. She is now much more faithful to the anime, and all her scenes have been rebuilt to match the quality of the newer content.
Updated Hina animations include:
Handjob (morning, at the command zone)
Blowjob (night, in Hina’s quarters)
Cowgirl (night, in Hina’s quarters)
Reverse Cowgirl (morning, waking up together)
Doggystyle (on Hina’s ship)
Other Character Updates
The Midou NTR scene with Jack has been remastered
Kana has been completely rebuilt from scratch, with a new model and fully new night scenes at the port
Alvida has also received an updated model, and all of her sexual animations have been remastered as well.
The 3D models of Koby and Umi have also been updated, improving their overall visual quality and making them fit much better with the current standard of the game
Background & Visual Improvements
Several backgrounds have been updated to improve the visual consistency of the game, including:
Port
Plaza
Command Zone
Courtyard
Tavern
The Nefertari Vivi ship button has also been completely redesigned. This ship is now called Vanguard Karoo, and has been designed by none other than Franky himself.
Midou Bath Scene Update
The Midou bath scene has also been updated using Coral’s new foot mod. I also decided to remove some of the more “dream-like” or overly magical feeling it had before. Now it feels much more grounded and realistic — just as it should be, since it’s meant to be a real intimate bath moment with Midou, not a fantasy sequence.
v0.3.1

talking to Yui and Ran at night.
Fixed the issue that
