Re:BirthStone ~誕生石物語~

Leave the Taskbar Mode window open and your birthstone envoys keep exploring and leveling up while you work or play something else. Open the main game and two opposing stories await: party battles on the God Side, tower defense and castle-town building on the Demon King Side.

The Developer Says...

Re:BirthStone is an RPG/strategy about raising 24 birthstone envoys across two opposing stories — the God Side and the Demon King Side.

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.
