A theatrical tale of two girls who have lost their memories, set on a beautiful, eerie, and sorrowful stage, with secrets hidden within the theater awaiting you.

Prepare the Stage with Dynamic Actions



The gems scattered throughout the map are broken musical notes. Use Aleph’s abilities to tune the broken notes, restore the stage props, play the music, and get ready to open the curtains!

Complete the Performance on the Prepared Stage



Musicals featuring tales such as The Wizard of Oz, Cinderella, and The Legend of King Arthur! As Liora successfully completes her performances, the theater will regain its vitality.

And Uncover the Truth Behind It All…

""Aleph"" and ""Liora"", having lost their memories, take on the roles of stage director and actress. Together, they delve into the secrets hidden within the theater through their performances.

Your choices will determine their fate.
