The story of Deemo and little girl has come to an end!

From Cytus team, a world acclaimed music rhythm game.

Rayark brings you Deemo, a hybrid of music rhythm game and the story of urban fantasy, with hand-drawn art, story-telling gallery and real instrumental feedback of piano key sound.

Deemo is a mystic character who lives in solitude in a castle all by itself. A little girl falls from the sky, not knowing who she is, where she comes from. To help the little girl back to her world, Deemo comes to realize a tree keeps growing tall on top of the piano whenever it plays. What would Deemo do when it gets comfortable with the companionship it never had before? What if the little girl couldn't deal with the truth when her seemingly lost memories regained?!

"Never left without saying goodbye".
