Sail Girl

The release date for Sail Girl is July 22, 2026, for PC. Developed by HKSTTNT and published by Nutaku Publishing, this idle RPG centers on building a fleet of more than 70 anime crewmates to hunt for the legendary Blue Pearl. It blends automatic progression with gacha collection and social systems designed to strengthen your squad through character interaction.

The loop moves between seafaring voyages and minigames like horse racing and puzzles, but the real focus is on managing your roster and unlocking individual stories through hot spring dates and bonding events. As an idle title, the emphasis is on the long-term recruitment grind and the steady growth of your crew's power rather than active mechanical skill. This is a dedicated choice for collectors who want a low-maintenance maritime adventure with heavy dating-sim elements. Pick this up if you want a casual, waifu-driven progression game for your library.
