Who Must You Defeat—the Demon King, or God?

One day, a voice from nowhere calls to you, drawing you into the story of girls who bear the names of birthstones. On nights of the full moon, you are 《God》. On nights of the new moon, you are the 《Demon King》. Move freely between both sides, and awaken the true power of the girls divided between light and darkness.

A World That Grows While You Play

Keep a lightweight companion open beside your taskbar and check in between work—or another game. The God-side companion follows your pilgrimage and idle exploration, while the Demon-side companion tracks castle production and development. You do not need to stay glued to the screen. Collect what has accumulated, set your next direction, and return to your day. When you want a more active session, open the full game for 4v4 battles, story chapters, and tower defense.

A God at the Full Moon. A Demon King at the New Moon.

Two parcels arrive from a prize campaign he does not remember entering. Inside: two birthstones and a QR code. On the night of the full moon, an ordinary young man is pulled into another world as a bodiless God. He resonates with the birthstone heroines, sharing their senses and awakening powers neither could wield alone. At the new moon, the same protagonist is called to a second role: the Demon King. Are light and darkness truly the same as good and evil? The God meant to save the world enters the Demon Castle and orders construction instead of destruction. Even the “enemy” has a home worth protecting.

God Side — Raise the Twelve Envoys for 4v4 Battles

Recruit the Twelve Birthstone Envoys and shape their growth through levels, equipment, skills, and awakening. Build a team whose roles work together, then lead them into 4v4 battles.

Demon Side — Build a Realm Worth Defending

Gather nine resources, construct facilities, and develop the castle town. Your Demon Castle is more than a battlefield: it is a living realm with homes to protect and a future to build.

Twelve Birthstones. Two Faces of Fate.

Under the full moon stand the Twelve Envoys of Light. Under the new moon wait the Twelve Generals of Darkness. The same birthstones reveal different faces when their loyalties and destinies change. Keep it small on busy days. Dive deep when you have time. Re:BirthStone is designed as two worlds that keep growing beside your everyday life.
