About the Game
Re:BirthStone is an RPG/strategy about raising 24 birthstone envoys across two opposing stories — the God Side and the Demon King Side.The game features both Japanese and English voice audio.
Leave the Window Open and the Adventure Keeps Going
In Taskbar Mode, a small window keeps your envoys exploring and growing in real time. Resize it however you like, and as long as you leave it open you can close the main game entirely. Work, play something else — your envoys keep fighting and leveling up. Come back to collect what they earned, then jump straight into the main game.24 Birthstone Envoys
Twelve envoys on the God Side, twelve on the Demon King Side. Raise your favorites, build out their equipment, skills, and costumes, and form a party that is entirely your own.Two Sides, Two Ways to Play
On the God Side, take a hand-picked party of four into battle. On the Demon King Side, command tower defense against the invasion, build the Demon King's Castle, and grow the castle town around it. One world, two completely different ways to play.So Who Do You Bring Down — the Demon King, or the Gods?
Neither side is willing to give up what it stands for. Follow the ties between the birthstone envoys and close in on the truth behind the two opposing sides.Explore 3D Fields
Explore supported areas as 3D fields. Some envoys appear as 3D models; envoys without a supported 3D model use 2D visuals.This is an Early Access version; available content and game balance may change with updates.
